Quick answer

A codicil amends your existing will, while a new will replaces it entirely. For most changes a new will is the safer, clearer choice, but both must be executed with the same formalities to be valid.

  • Use a codicil for: Single, minor changes such as updating an address or adding a small gift.
  • Make a new will for: Multiple changes, significant alterations, or if you already have codicils.
  • Same execution either way: Signed by you in front of two witnesses present together (ideally independent adults).
  • A clean replacement: New wills should include a revocation clause, and old wills should be destroyed.

When your circumstances change, you need to update your will. The question is whether to add a codicil to your existing will or create an entirely new one. Making the wrong choice can lead to confusion, disputes, or even an invalid document.

The Cost of Getting It Wrong

Will disputes can arise from improperly amended wills, from estates where multiple codicils created confusion, and from handwritten alterations on a signed will. Contested estates can take a long time to resolve, and legal costs are often paid out of the estate, reducing what your beneficiaries receive.

Why This Decision Matters

Situation Wrong Choice Consequence
Multiple codicils Creates "document chain" confusion leading to disputes
Major changes via codicil Higher challenge risk, courts scrutinize significant codicil changes more
No revocation clause Both wills may apply, causing executor nightmare
Not destroying old will Wrong will may be submitted to probate
Writing on existing will Generally not a valid change; may lead to a court dispute about what you intended

Why This Matters

A will can fall out of date after marriage, separation, new children or new assets. Keeping your will current matters as much as making one.

What Is a Codicil?

Definition

A codicil is a separate legal document that makes specific amendments to an existing will without replacing the entire will. Think of it as an "addendum" or "amendment" to your original will.

The word "codicil" comes from the Latin codicillus, meaning "a short writing" or "little book." In modern Australian succession law, a codicil must be executed with the same formalities as a will to be legally valid.

Historical Context

Before digital document creation became widespread, codicils were the practical solution for making minor changes. Creating an entirely new will meant rewriting everything by hand or paying for complete re-drafting. Today, with word processing and online will platforms, creating a new will is often just as easy, and usually safer.

How Codicils Work

Aspect Details
Purpose Amends specific provisions in existing will
Legal status Becomes part of your will, read together
Execution Same requirements as a will (signed, two witnesses)
Storage Must be stored with the original will
Number allowed Multiple codicils possible (but strongly not recommended)
Legal reference Various state Succession/Wills Acts
Interpretation Later codicil prevails over earlier will where inconsistent
Revocation Revoking will also revokes all codicils to it

How Courts Interpret Codicils

Principle Explanation
Reading together Will and codicil(s) are read as a single document
Later prevails Where inconsistent, the later-dated document prevails
Specific prevails Specific provisions override general ones
Presumption of validity Courts try to give effect to both documents where possible
Testator's intention Overall goal is to give effect to what the will-maker intended

Example Codicil Wording

"This is the First Codicil to my Will dated [date].

I revoke the appointment of [old executor] as Executor and Trustee and appoint [new executor] in their place.

In all other respects I confirm my said Will.

Signed by me on [date]."

Alternative Codicil Formats

Format 1: Adding a Beneficiary

"This is the First Codicil to my Will dated [date].

I give the sum of $10,000 to my nephew, James Robert Smith of [address], free of all duties.

In all other respects I confirm my said Will."

Format 2: Changing a Specific Gift

"This is the First Codicil to my Will dated [date].

I revoke clause 4 of my said Will and substitute the following:

'I give my piano to my granddaughter Emily Jane Brown.'

In all other respects I confirm my said Will."

Format 3: Updating Contact Details

"This is the First Codicil to my Will dated [date].

The address of my Executor, John Smith, referred to in my said Will is now [new address].

In all other respects I confirm my said Will."

Legal Standing of Codicils in Australia

All Australian states and territories recognise codicils under their succession legislation:

State/Territory Legislation Execution requirements
NSW Succession Act 2006 s 6
VIC Wills Act 1997 s 7
QLD Succession Act 1981 s 10
SA Succession Act 2023 (SA) s 8
WA Wills Act 1970 s 8
TAS Wills Act 2008 s 8
ACT Wills Act 1968 s 9
NT Wills Act 2000 s 8

When to Use a Codicil

Key point

A codicil is only suitable when ALL conditions hold: a single minor or administrative change, a will less than 3 years old, no existing codicils, and no effect on major distributions. For anything else, make a new will instead.

The Reality: Codicils Are Rarely the Best Choice

While codicils are legally valid, modern estate planning practice generally favours creating new wills for anything beyond a minor change.

Why? Because the marginal cost savings of a codicil are usually outweighed by:

  • Increased risk of document chain confusion
  • Higher probability of probate delays
  • Greater likelihood of challenges
  • Storage and location issues (codicil must stay with will)

Appropriate Uses for Codicils

Change Type Example Codicil Suitable? Risk Level
Address update Executor moved house ✓ Yes Low
Name correction Beneficiary's legal name changed ✓ Yes Low
Small gift addition Adding $5,000 to a charity ✓ Possibly Medium
Executor address Updating contact details ✓ Yes Low
Minor clarification Specifying which "John Smith" ✓ Yes Low
Single small bequest change Changing $10,000 gift amount ⚠ Consider new will Medium
Correcting typo Misspelled name ✓ Yes Low

When a Codicil Is Genuinely Appropriate

A codicil may be appropriate when:

Scenario Why Codicil Works Example
Truly minor administrative change Not worth full will review Updating executor's phone number
Very recent will Will is less than 1 year old and otherwise perfect Will made 6 months ago, executor moved
Single isolated correction One small thing to fix Typo in beneficiary's surname
No material change to distributions No one's inheritance changes Clarifying asset description
Clear, simple original will Original will is straightforward Simple will with few provisions

Codicil Suitability Checklist

Use a codicil only if ALL of these apply:

  • You're making only ONE change
  • The change is minor/administrative
  • Your existing will is recent (less than 3 years old)
  • Your existing will is clear and well-drafted
  • You have NO existing codicils
  • The change doesn't affect major distributions
  • The change doesn't create any inconsistencies
  • The change doesn't involve significant assets
  • All parties named in will are still alive
  • Your family circumstances haven't changed
  • You haven't had a major life event

If any of these don't apply, make a new will instead.

The "One Codicil Rule"

Estate planning professionals generally follow the "one codicil rule":

Rule Explanation
First codicil Acceptable for minor administrative changes
Second codicil Almost never recommended, make a new will
Third+ codicils Never appropriate, always make new will
Any significant change Skip codicil, make new will

Hypothetical Example: When a Codicil Works

Situation: Suppose someone made a clear, recent will and the only change since is that their executor has moved interstate.

Appropriate Action: A single codicil updating the executor's address.

Why This Works:

  • Will is recent and clear
  • Single administrative change
  • No change to distributions
  • No existing codicils
  • Same executor (just a different address)

When to Make a New Will

The Default Recommendation: New Will

For most situations requiring will changes, a new will is the recommended approach. The marginal extra cost is almost always justified by the reduced risk and increased clarity.

Situations Requiring a New Will

Situation Why New Will Required Challenge Risk if Codicil Used
Multiple changes needed Creates clearer single document High
Major beneficiary changes Reduces challenge risk significantly Very High
Adding/removing executor Better stated in fresh will High
Marriage Marriage generally revokes previous wills anyway N/A (automatic, exceptions vary by state)
Divorce Fresh start reflects new circumstances High
Existing codicil(s) Prevents document chain confusion Very High
Will is 5+ years old Complete review warranted Medium
Adding trusts Complex provisions need clean document Very High
Structural changes New distribution scheme Very High
Major life event Children, death of beneficiary, inheritance High
Significant asset changes New property, business, superannuation High
Relocation interstate Different state laws may apply Medium
Beneficiary dies Need to reallocate their share High
Family dispute arises Clear fresh document reduces challenge Very High

The Document Chain Problem

Consider this scenario:

Documents Problems Created
Will (2015) Original document
Codicil 1 (2017) Changes executor
Codicil 2 (2020) Adds gift to charity
Codicil 3 (2023) Changes residue distribution

What happens at probate:

  • Executor must locate and read all 4 documents
  • Risk of inconsistencies between documents
  • Increased chance of errors or misinterpretation
  • Higher likelihood of challenges
  • More complex probate process
  • Higher legal fees for executor
  • Longer administration timeline
  • Greater chance of court rectification applications

Solution: A single new will in 2023 would be clearer and safer.

Hypothetical Example: The Document Chain Problem

A hypothetical illustration, not a real case.

Suppose a will-maker adds four codicils over the years: one changing the executor, one adding a gift to a church, one changing the residue split between the children, and a last one removing an estranged child.

What can go wrong:

  • Two codicils both deal with the residue but use different language
  • One codicil is not stored with the will and turns up separately
  • An earlier executor appointment conflicts with wording in a later codicil
  • A family member argues that the last codicil was made under undue influence

The likely result: delay, legal costs paid from the estate, family conflict, and a court having to work out what the will-maker intended.

Prevention: A single new will incorporating all the changes would have avoided the document chain entirely.

Hypothetical Example: The Hidden Codicil

A hypothetical illustration, not a real case.

Suppose a parent's will leaves everything equally to three children, and a later codicil leaves the home to the daughter who cared for them. The codicil is kept in personal papers, not with the will, so the executor finds only the will and applies for probate on it.

If the codicil turns up later:

  • The estate may already be partly distributed
  • Legal steps may be needed to correct the distribution
  • Beneficiaries may have to return money already received

Prevention: A new will (a single, clear document), or at least keeping the codicil with the will, would have prevented this.

Life Events That Always Require a New Will

Life Event Why New Will Required Consequence of Not Acting
Marriage Previous will generally revoked (all states and territories; exceptions vary) Die wholly or partly intestate despite having a will
Divorce Gifts to ex-spouse and their role as executor generally removed (in WA the whole will is generally revoked) Unintended distributions or executor issues
New child Child needs to be included Child may have family provision claim
Child dies Their share needs reallocation Gifts may fail, going to residue
Executor dies Need new executor Court may appoint administrator
Major inheritance New assets need addressing Assets may not pass as intended
New business Business succession needs planning Business may need to be sold to satisfy estate
Interstate move Different state laws apply Will may not be optimally drafted for new state
Buying property New assets to distribute Property may pass outside will through joint ownership
Superannuation changes Death benefit nominations need review Super may not align with will

The "5-Year Rule" for New Wills

Estate planning professionals recommend reviewing your will at least every 5 years, even if no major changes have occurred. This is because:

Factor Why Regular Review Matters
Asset values change A $50,000 gift in 2015 may be disproportionate to 2025 estate
Laws change Tax laws, succession laws, superannuation rules all evolve
Relationships evolve People named may no longer be appropriate
Executors age Your 60-year-old executor is now 65, still appropriate?
Witness availability Key witnesses may have died, moved, or become untraceable
Memory fades You may have forgotten details of your own will
Digital assets accumulate Cryptocurrency, online accounts, digital subscriptions
Family circumstances Grandchildren born, adult children's situations change

Comparison Table: Codicil vs New Will

At-a-Glance Comparison

Factor Codicil New Will
Best for Single minor change Multiple or significant changes
Cost (online) $30-$80 $39-$200
Cost (lawyer) $100-$300 $300-$800+
Execution requirements Same as will Same as will
Witnesses needed Two (adults best) Two (adults best)
Creates multiple documents Yes No (single document)
Risk of confusion Higher with multiples Lower
Challenge risk Higher with multiples Lower
Old will handling Keep with codicil Destroy after new signed
Recommended approach Rarely Usually
Probate complexity Increases with each codicil Single document review

Detailed Cost-Benefit Analysis

Scenario Codicil Cost New Will Cost Recommendation
Update executor address $50-$150 $150-$500 Codicil acceptable
Add a small charity gift $75-$200 $150-$500 Consider new will
Change main beneficiary N/A $200-$600 New will only
Add testamentary trust N/A $500-$1,500 New will only
Remove estranged child N/A $300-$800 New will + legal advice
Update after divorce N/A $300-$800 New will always

Document costs are indicative only and vary by provider and complexity. If an estate is disputed, legal costs can far exceed the cost of the document.

Long-Term Cost Analysis

Over a 20-year period with periodic changes:

Approach Individual Cost 20-Year Total Risk Assessment
New will every 5 years $150-$500 each $600-$2,000 Low dispute risk
Multiple codicils $50-$150 each $200-$600 (4 codicils) High dispute risk
Mixed approach Varies $400-$1,200 Medium dispute risk
No updates $0 $0 Very high dispute risk + intestacy issues

The Reality: The "savings" from using codicils can disappear when you factor in:

  • Higher probate fees for multiple documents
  • Increased executor time and complexity
  • Higher professional fees during administration
  • Substantially higher litigation risk

Time Investment Comparison

Task Codicil New Will
Initial drafting 15-30 minutes 45-90 minutes
Review of existing will Required Part of process
Execution ceremony Identical Identical
Storing documents Must store with will Single location
Explaining to executor More complex Straightforward
Probate submission Multiple documents Single document
Court review time Longer Shorter

Proper Execution Requirements

Key point

A codicil requires exactly the same formalities as a will: you must sign it in front of two witnesses present together, who then sign in your presence. Best practice: sign at the end, use adult witnesses who are not beneficiaries, and have everyone stay together while all three sign.

Why Execution Matters

A will or codicil that is not signed and witnessed correctly may not be accepted for probate without extra evidence or a court application. Improper execution is a common source of problems with will validity.

Codicil Execution

A codicil requires exactly the same formalities as a will:

Requirement Details Common Mistake
In writing Typed or handwritten (typed preferred) Verbal amendments don't count
Signed by you At the end of the codicil (best practice; required in the ACT) Signing elsewhere invites doubt
Two witnesses Ideally independent adults, not beneficiaries (no Act sets a minimum age) Using beneficiary as witness
Witnesses present together Both there when you sign Sequential witnessing fails
Witnesses sign In your presence (each other's presence is best practice, required in the ACT) Witness signing out of your sight
Reference to will Should identify the will it amends Vague reference creates confusion
Dated Date clearly stated Undated codicils create interpretation issues

New Will Execution

Requirement Details Common Mistake
In writing Typed document Verbal wills (only valid in rare circumstances)
Revocation clause "I revoke all previous wills and codicils" Forgetting to include, creating multiple valid wills
Signed by you At the end of the will Signing first page only
Two witnesses Ideally independent adults, not beneficiaries (no Act sets a minimum age) Using family members who benefit
Witnesses present together Both there when you sign "Round-robin" witnessing
Witnesses sign In your presence (and ideally each other's; required in the ACT) Witness going outside to sign
Attestation clause Witnesses confirm correct execution Missing attestation clause
Initialling pages Each page initialled by will-maker and witnesses Unsigned pages

Witnessing Procedure: Step-by-Step

Step What Happens Critical Detail
1 You, and both witnesses, gather in same room Best to stay together throughout (the ACT requires witnesses to sign in each other's presence)
2 You acknowledge this is your will/codicil Can be verbal acknowledgment
3 You sign the document while both witnesses watch Sign at the end, after all provisions
4 First witness signs while you and second witness watch Best practice: all three remain together
5 Second witness signs while you and first witness watch Best practice: no one leaves the room
6 Witnesses add their names, addresses, occupations Printed clearly under signatures
7 Date added if not already present Same date for all signatures

Who Should NOT Be a Witness

Avoid Reason Risk Level
Beneficiaries Gift to them can fail (NSW, QLD, TAS, NT) Critical
Spouse/partner of beneficiary Undermines independence (best avoided) Medium
Anyone under 18 No Act sets a minimum age, but an adult can better explain later what happened Medium
Someone lacking capacity May invalidate document High
Spouse of will-maker Creates presumption issues in some states Medium
Someone who can't see you sign Blind witnesses problematic Medium
Executors who are also beneficiaries Complex, generally okay but creates scrutiny Low
Anyone with interest in estate Creates appearance of undue influence Medium

Ideal Witness Characteristics

Characteristic Why It Matters
Adult (18+) Best practice (no Act sets a minimum age)
No benefit under will Prevents gift failure
Independent of family Reduces challenge risk
Good health Available if needed later
Younger than will-maker Available to testify if will challenged
Known, locatable Can be found if questions arise
Professional if possible Lawyers, accountants, JPs ideal

Hypothetical Example: The Witness Problem

A hypothetical illustration, not a real case.

Suppose a will-maker signs a codicil leaving a cash gift to a neighbour, and the witnesses are the will-maker's spouse and daughter. The daughter is also the residuary beneficiary, so the new gift reduces her share.

What can go wrong:

  • The family may assume the neighbour's gift fails because a beneficiary witnessed the codicil
  • In fact the interested-witness rules only put a gift to the witness at risk (for example, s10 Succession Act 2006 (NSW)), and in VIC, SA, WA and the ACT even that gift is not void
  • The neighbour's gift was always payable, but the estate may spend money and time establishing this

Prevention: Use two independent witnesses with no interest in the estate.

State-Specific Execution Requirements

All states require the same basic formalities, but courts have different approaches to fixing defects:

State Informal Will Provision Likely to Fix Defects?
NSW Yes (s 8 Succession Act 2006) More likely
VIC Yes (s 9 Wills Act 1997) More likely
QLD Yes (s 18 Succession Act 1981) More likely
SA Yes (s 11 Succession Act 2023 (SA)) More likely
WA Yes (s 32 Wills Act 1970) More likely
TAS Yes (s 10 Wills Act 2008; the court must be satisfied beyond reasonable doubt) Higher bar
ACT Yes (s 11A Wills Act 1968) More likely
NT Yes (s 10 Wills Act 2000) More likely

Important: While courts can validate informally executed wills, this requires a court application, which adds cost and delays probate. Always execute properly to avoid this.

How to Properly Revoke a Will

The Critical Importance of Proper Revocation

Improper revocation can leave your family unsure which document applies. Common problems:

  • Multiple wills found with no clear revocation
  • Destroyed wills where no replacement exists
  • Partial destruction creating ambiguity
  • Revocation without valid replacement (dying intestate)

Valid Revocation Methods

Method How It Works Recommended? Risk Level
New will with revocation clause Explicitly states all prior wills revoked ✓ Yes, Always Lowest
Physical destruction Burn, tear, shred with intent to revoke With caution Medium
Marriage Generally revokes prior wills Automatic (all states and territories; exceptions vary) N/A
Written declaration A document that says you cancel your will, signed and witnessed the same way as a will Rarely used Medium

Revocation by New Will: The Gold Standard

The revocation clause in your new will should read:

"I revoke all former wills and codicils and declare this to be my last will."

This is the safest revocation method because:

Advantage Explanation
Clear and explicit No ambiguity about intention
Documented Evidence of revocation is in a witnessed document
Simultaneous Old will revoked at exact moment new will takes effect
Comprehensive Catches all previous wills and codicils

What Does NOT Revoke a Will

Action Why It Fails What Happens
Crossing out text Not a reliable form of revocation Court may have to decide what you intended
Writing "cancelled" Ambiguous, may cause disputes Court must interpret intention
New will without revocation clause Both wills may apply where consistent Multiple documents to interpret
Verbal statement Must be in writing Ignored by courts
Losing the will Lost will can still be proved Estate administered under lost will
Giving will to someone Custody change ≠ revocation Will still valid
Tearing slightly Intent unclear May or may not be revoked
Deleting electronic copy Original paper will controls No effect on validity

Revocation by Destruction: Getting It Right

If you choose to revoke by destruction (not recommended as sole method):

Requirement Details
Intent to revoke Must intend to cancel the will permanently
Actual destruction Must be substantially destroyed (not just marked)
By you or in your presence Someone else can destroy if you direct and watch
Original document Destroying copies doesn't revoke the will
All parts Must destroy entire will, not just signature page

Hypothetical Example: The Incomplete Destruction

A hypothetical illustration, not a real case.

Suppose a will-maker's will leaves everything to their spouse, with their brother as the backup beneficiary. After a divorce, the will-maker tears the will in half but never makes a new one.

What can go wrong:

  • The torn pieces are found in their papers after death
  • The brother argues the will still stands, because the tearing might have been accidental or half-hearted
  • The children argue it was torn with the intention of revoking it, which would leave the estate to pass under intestacy

The likely result:

  • A court dispute over one question: intent
  • If intent to revoke is proved, the whole will is revoked and the estate passes under the intestacy rules
  • If it is not proved, the will stands (with gifts to the former spouse cancelled by the divorce)

Prevention: Make a new will with a revocation clause after divorce.

Marriage and Revocation

Marriage generally revokes previous wills in every Australian state and territory, subject to exceptions that vary by state:

State Effect of Marriage on Previous Will
NSW Revokes previous will (s 12 Succession Act 2006)
VIC Revokes previous will (s 13 Wills Act 1997)
QLD Revokes previous will (s 14 Succession Act 1981)
SA Revokes previous will (s 18 Succession Act 2023 (SA))
WA Revokes previous will (s 14 Wills Act 1970)
TAS Revokes previous will (s 16 Wills Act 2008)
ACT Revokes previous will (s 20 Wills Act 1968)
NT Revokes previous will (s 14 Wills Act 2000)

Exception: A will made "in contemplation of" a particular marriage is generally not revoked by that marriage. In NSW, VIC, QLD, TAS and NT this can apply even if the will does not say so; in WA the will must say so or other evidence must show it; in SA and the ACT the will must be expressed to be made in contemplation of it, so it is safest to state it expressly. In NSW, VIC, QLD, TAS and NT, gifts to and appointments of the person you are married to when you die also survive. Check the guide for your state, for example How to Make a Will in South Australia.

Divorce and Revocation

In most states divorce does NOT revoke your whole will, but it does affect certain provisions. Western Australia is the exception: divorce generally revokes the whole will (How to Make a Will in Western Australia):

State Effect of Divorce on Will
NSW Gifts to ex-spouse fail; ex loses executor role (s 13)
VIC Gifts to ex-spouse fail; ex loses executor role (s 14)
QLD Gifts to ex-spouse fail; ex loses executor role (s 15)
SA Gifts to ex-spouse fail; ex loses executor role (s 19)
WA Whole will generally revoked, unless a contrary intention appears (s 14A)
TAS Gifts to ex-spouse fail; ex loses executor role (s 17)
ACT Gifts to ex-spouse fail; ex loses executor role (s 20A)
NT Gifts to ex-spouse fail; ex loses executor role (s 15)

Critical Warning: Even though the law provides some protection, always make a new will after divorce. The automatic provisions are a backstop, not a complete solution.

Best Practice Revocation Process

Step Action Why It Matters
1 Execute new will with clear revocation clause Creates clear, documented revocation
2 Ensure new will is properly witnessed New will must be valid to take effect
3 Store new will safely Executor must be able to find it
4 Physically destroy old will (tear into pieces or burn) Prevents old will being found and used
5 Destroy or mark all copies "REVOKED - [date]" Eliminates confusion over copies
6 Notify executor of new will location Ensures correct will is found
7 Update any will registry if applicable Keeps records current
8 Consider storing with lawyer or trustee company Professional safekeeping available

What to Do with Old Will Copies

Location Action Notes
Your safe Shred original Keep only current will
Lawyer's file Request destruction Get confirmation in writing
Family member Retrieve and destroy Don't leave copies with family
Safe deposit box Retrieve and destroy Update box contents
Online backup Delete Digital copies can cause confusion
Unknown locations Mark new will clearly "This replaces all previous wills"

State-Specific Rules

Understanding state-specific rules is important because while the core principles are similar across Australia, there are variations in:

  • Legislation references
  • Court discretion to save gifts
  • Specific revocation provisions
  • Filing and probate procedures

New South Wales

Aspect NSW Rule
Legislation Succession Act 2006
Codicil requirements Same as will (ss 6-10)
Revocation methods s11 - later will, a document that says you cancel it (signed and witnessed the same way as a will), or destruction; s12 - marriage
Witness beneficiary Gift generally void unless an exception applies (s10)
Court can save gift Yes, if satisfied you knew and approved of the gift and made it freely and voluntarily (s10)
Informal will provision s8 - court can validate document showing testamentary intention
Probate Registry Supreme Court of NSW, Probate and Estate Administration
Typical codicil probate fee Included in will probate fee (based on estate value)

NSW-Specific Considerations:

  • NSW courts are relatively willing to validate informal documents
  • Family provision claims must be filed within 12 months of death
  • Signing can be witnessed by audio visual link under the Electronic Transactions Act 2000 (NSW) Part 2B (s14G), but every step must be followed

  • Will challenges must be brought in Supreme Court

Queensland

Aspect QLD Rule
Legislation Succession Act 1981
Codicil requirements Same as will (ss 10-17)

Court can save gift Yes, on application
Informal will provision s18 - court may dispense with execution requirements
Probate Registry Supreme Court of Queensland, Probate Registry
Typical codicil probate fee Included in will probate fee (based on estate value)

  • Specific provisions for agricultural estates

Western Australia

Aspect WA Rule
Legislation Wills Act 1970
Codicil requirements Same as will (ss 8-12)
Revocation methods ss 14-15 - new will, a document that says you cancel it (signed and witnessed the same way as a will), destruction, marriage

  • Family provision claims generally within 6 months from when the executor or administrator becomes entitled to administer the estate (Family Provision Act 1972 (WA) s7(2))
  • More formal approach to will execution
  • Specific rules for remote and Indigenous communities

Tasmania

Aspect TAS Rule
Legislation Wills Act 2008
Codicil requirements Same as will (ss 8-12)
Revocation methods ss 15-17 - new will, a document that says you cancel it (signed and witnessed the same way as a will), destruction, marriage

Common Mistakes to Avoid

Many problems with contested estates could have been avoided with proper will update procedures. The following mistakes are among the most common.

Codicil-Specific Mistakes

Mistake Problem Solution
Writing on original will Generally not a valid change; may cause a dispute Use separate codicil document
Not referencing will Unclear which will amended Specify date of original will
Vague language Ambiguous instructions Use precise legal terminology
Not storing together Codicil may be missed Keep the codicil with the will (e.g. in the same envelope), without stapling or clipping it to the will
Multiple codicils Creates confusion Make new will instead
Contradictory provisions Unclear testator intent Review entire will before adding
Informal execution Invalid codicil Follow strict execution rules

Hypothetical Example: The Written Amendment

A hypothetical illustration, not a real case.

Background: Suppose a will-maker in Victoria writes in pencil on their signed will: "I now want to leave my car to James instead of Peter."

What can go wrong:

  • Peter says the pencil note is not a valid amendment
  • James says it shows the will-maker's final intention
  • A court may have to decide whether the note operates as part of the will

The likely result:

  • A court may admit an informal document under its dispensing power (s9 of Victoria's Wills Act), but it must be satisfied the will-maker intended the note to operate as part of their will; this takes an application and is never guaranteed
  • Legal costs and delay that a proper codicil would have avoided

Lesson: Even simple changes require formal execution to avoid costly disputes.

New Will Mistakes

Mistake Problem Solution
No revocation clause Both wills may apply Include explicit revocation
Not destroying old will Confusion over which applies Destroy after new signed
Same witnesses as beneficiaries Gifts to witnesses may fail Use independent witnesses
Not telling executor Old location checked first Notify of new will
Keeping old copies May be mistaken for valid Destroy or clearly mark
Inconsistent with codicil Conflict between documents Start completely fresh
Rushed execution Procedural defects Follow checklist carefully

Hypothetical Example: The Undestroyed Will

A hypothetical illustration, not a real case.

Background: Suppose a will-maker makes a new will, lodged with their solicitor, but keeps the earlier will at home "just in case."

What can go wrong:

  • After death, family find the earlier will in a desk drawer
  • The earlier will favours different family members
  • Some family members argue the will-maker meant the earlier will to apply

The likely result:

  • A later, properly executed will with a revocation clause will generally prevail, but the dispute can still cost the estate time and money
  • Family relationships can be damaged

Lesson: Old wills should be physically destroyed to prevent claims about testamentary intent.

Prevention Checklist

Before Making Any Changes:

  • Review your current will completely (not just the section to change)
  • List all changes you want to make
  • Consider if a new will would be simpler
  • Check if you already have any codicils
  • Verify your will is less than 5 years old

During the Update:

  • Use proper legal language (not casual notes)
  • Reference original will by date
  • Ensure complete consistency with existing provisions
  • Follow all execution requirements
  • Use two independent adult witnesses

After the Update:

  • Store codicil with original will
  • Notify executor of changes
  • Destroy any old documents that might cause confusion
  • Keep a record of what you changed and why
  • Consider a professional review if changes are significant

Decision Guide: Codicil or New Will?

Making the right choice between a codicil and new will can help avoid unnecessary cost and family conflict. Use these decision tools to determine the best approach for your situation.

The New Will Rule

In most cases, a new will is the better choice. The situations where a codicil is genuinely appropriate are quite narrow:

Codicil Appropriate New Will Required
Single administrative change Any substantive change
Address update only Multiple changes (even small ones)
Minor spelling correction Already have 1+ codicils
First and only change Will over 5 years old
Simple, uncontested estate Complex family dynamics

The "Hidden Cost" Analysis

When comparing costs, consider more than the upfront price. A codicil may cost less to prepare, but if it creates confusion or a dispute, the legal costs are usually paid from the estate and can far exceed the cost of a new will.

Key insight: Even when a codicil costs less upfront, a single clear new will is often the more economical choice once you allow for the risk of a dispute.

Scenario-Based Recommendations

Scenario 1: Simple Address Update

Situation: Your executor moved interstate. Nothing else needs changing.

Factor Status
First change? ✓ Yes
Single change? ✓ Yes
Will age ✓ Under 5 years
Administrative only? ✓ Yes
Asset distribution affected? ✓ No

Recommendation: Codicil suitable Cost: $50-$150 for codicil vs $200-$400 for new will Risk: Low

Scenario 2: Add a Small Gift

Situation: Want to add a $10,000 gift to your nephew.

Factor Status
First change? Depends on history
Single change? ✓ Yes
Will age Check
Administrative only? ✗ No, affects distribution
Asset distribution affected? ✓ Yes

Recommendation: New will preferred Why: Any change to distribution increases dispute risk Cost difference: A new will usually costs a little more than a codicil

Scenario 3: Post-Divorce Update

Situation: Recently divorced, need to remove ex-spouse as beneficiary.

Factor Status
Major life event? ✓ Yes
Single change? ✗ No, affects multiple provisions
Dispute potential? Very high
Comprehensive review needed? ✓ Absolutely

Recommendation: New will essential Why: Divorce affects superannuation, insurance, and trusts beyond the will Cost: $400-$800 for comprehensive new will Risk of codicil: Extremely high dispute probability

Scenario 4: Multiple Small Changes

Situation: Want to update executor's address, add a charity gift, and correct a name spelling.

Factor Status
Single change? ✗ No, three changes
Codicil appropriate? Never for multiple changes
Clarity concern? High

Recommendation: New will required Why: Multiple codicils or complex single codicil creates confusion Cost: $200-$500 for new will

Professional Guidance Triggers

Always consult a solicitor before deciding if:

  • Your estate exceeds $500,000
  • You have a blended family
  • There's any history of family conflict
  • You have business interests
  • You own property in multiple states
  • Any beneficiary has a disability
  • You're considering a testamentary trust
  • You've had a major life event (divorce, new child, illness)
  • Anyone might contest your will

Cost Comparison

Solicitor and online fees for codicils and new wills vary by provider, location and complexity. Major city solicitors typically charge more than regional practitioners, so ask for a quote before you start.

After Making Changes

The work doesn't end when you sign your codicil or new will. Proper post-execution steps matter: good document management after signing helps your executor find the right documents and avoids confusion.

Codicil Completion Checklist

Immediately After Signing:

  • Verify codicil properly drafted and complete
  • Confirm it references original will by exact date (e.g., "my Will dated 15 March 2021")
  • Ensure you signed in the presence of both witnesses
  • Confirm both witnesses signed in your presence and each other's presence
  • Verify witnesses printed their names and addresses legibly
  • Check no beneficiary under the codicil acted as a witness

Within 24 Hours:

  • Keep the codicil with the original will (e.g. in the same envelope); do not staple or clip anything to the original will
  • Store both documents in the same secure location
  • Make a note of the storage location

Within 1 Week:

  • Notify your executor of the codicil and its contents
  • Provide executor with storage location details

  • Tear into small pieces that cannot be reassembled
  • Burn completely (preferred if safe)
  • Shred using a cross-cut shredder
  • Destroy all copies of the old will

Within 1 Week:

  • Notify your executor of the new will
  • Inform executor of the old will's destruction
  • Provide executor with new will's storage location
  • Update any will registry entries
  • Notify your solicitor if they held the old will
  • Consider providing executor with a copy (clearly marked "COPY - ORIGINAL HELD AT [LOCATION]")

Within 1 Month:

  • Consider lodging or registering your new will where your state offers a will storage or registry service (optional)
  • Update your personal records with new will details
  • Review and update any binding death benefit nominations for superannuation
  • Consider reviewing insurance beneficiaries

Old Document Destruction Protocol

Critical: Improper disposal of old wills can lead to probate disputes.

Destruction Method Effectiveness Risk of Recovery Recommendation
Burning Excellent None Preferred method
Cross-cut shredding Very Good Very Low Acceptable
Strip shredding Poor High NOT recommended
Tearing Good Medium Use in combination
Marking "REVOKED" Poor N/A NOT sufficient alone
Throwing away Poor High NEVER do this

For copies held by others:

Who Holds Copy Action Required
Solicitor Request written confirmation of destruction
Bank safe deposit Retrieve and destroy personally
Family member Collect and destroy
Will registry Update registration
Executor Provide new document, request return of old

Notification Template

Use this template when notifying your executor of changes:

Dear [Executor Name],

I am writing to inform you that I have [made a codicil to / replaced] my Will.

[FOR CODICIL:]
On [date], I executed a Codicil to my Will dated [original will date].
This Codicil [briefly describe changes, e.g., "updates your address" or
"adds a gift to [charity name]"].

The Codicil is stored with my original Will at [location].

[FOR NEW WILL:]
On [date], I executed a new Will which revokes all previous Wills and Codicils.

My previous Will dated [date] has been destroyed. Please destroy any
copies you may hold.

My new Will is stored at [location].

Please acknowledge receipt of this notification.

Yours sincerely,
[Your name]

Storage Options Comparison

Storage Method Security Accessibility Cost Recommendation
Home safe Medium High $200-$500 once Good for most
Bank safe deposit High Medium $50-$200/year Complex estates
Solicitor's safe High Medium Often free Professional management
Public Trustee Very High Low Varies Government option
Will registry Medium Medium $30-$100 once Supplementary
With executor Low High Free NOT recommended
Filing cabinet Very Low Very High Free NOT recommended

Best practice: Primary storage in a home safe or with a solicitor, plus lodgement with a will storage service where your state offers one.

Practical Examples

These hypothetical scenarios help illustrate when to use a codicil versus making a new will. The people in them are invented. Each example includes the decision analysis, recommended action, and sample wording where appropriate.

Example 1: Simple Address Update (Codicil Appropriate)

Situation: Jennifer (52, NSW) made her will in 2022. Her executor, her brother Michael, recently moved from Sydney to Brisbane. His role remains the same.

Analysis:

Factor Assessment
First change to this will? ✓ Yes
Single change only? ✓ Yes
Will less than 5 years old? ✓ Yes (2 years)
Administrative change only? ✓ Yes
Distribution affected? ✓ No

Decision: Codicil appropriate

Sample Codicil Wording:

CODICIL TO THE WILL OF JENNIFER ANNE SMITH

I, JENNIFER ANNE SMITH of 45 George Street, Sydney NSW 2000,
DECLARE this to be the First Codicil to my Will dated 15 March 2022.

1. I hereby amend Clause 3 of my said Will to update the address of
 my Executor MICHAEL JAMES SMITH from "23 Harbour Road, Sydney NSW 2000"
 to "156 Brisbane Road, Fortitude Valley QLD 4006".

2. In all other respects I confirm my said Will dated 15 March 2022.

SIGNED by me on this [date] day of [month] [year]

_______________________
JENNIFER ANNE SMITH

SIGNED by the Testator in our joint presence and then by us in hers:

Witness 1: Witness 2:
Signature: ________________ Signature: ________________
Name: ____________________ Name: ____________________
Address: __________________ Address: __________________
Occupation: _______________ Occupation: _______________

Cost: Approximately $80-$150 if using a solicitor; free if DIY (but professional review recommended)

Example 2: Adding a Charity Gift (New Will Preferred)

Situation: Robert (68, Victoria) wants to add a $15,000 gift to a charity. His will is 3 years old with no previous changes.

Analysis:

Factor Assessment
First change to this will? ✓ Yes
Single change only? ✓ Yes
Will less than 5 years old? ✓ Yes
Administrative change only? ✗ No, affects distribution
Distribution affected? ✗ Yes

Decision: New will preferred (though codicil technically possible)

Why new will is better:

  • Any change to distribution increases dispute risk
  • This is an opportunity to review entire will
  • Cost difference is minimal ($150-$200 more)
  • Provides single, clear document

Sample New Will Clause (instead of codicil):

SPECIFIC GIFTS

I give the following gifts free of all duties and taxes:

(a) The sum of FIFTEEN THOUSAND DOLLARS ($15,000.00) to
 [charity's full legal name] (ABN [number]) for its
 general charitable purposes.

[Existing gifts continue...]

Example 3: Post-Divorce Update (New Will Essential)

Situation: Sandra (45, Queensland) divorced 6 months ago. Her will names her ex-husband as executor and primary beneficiary.

Analysis:

Factor Assessment
Major life event? ✓ Yes, divorce
Single change only? ✗ No, multiple provisions affected
Dispute potential? Very high
Comprehensive review needed? ✓ Absolutely

Decision: New will essential

Why codicil is completely inappropriate:

  • Divorce generally revokes gifts to the ex-spouse and their appointment as executor, but not every related provision, and the will may not reflect current wishes
  • Multiple clauses affected
  • Very high contest risk from ex-spouse
  • Need comprehensive review of all provisions
  • Superannuation and insurance need separate review

Action checklist for Sandra:

  • Make entirely new will
  • Appoint new executor
  • Review all beneficiaries
  • Update superannuation binding death benefit nomination
  • Review insurance beneficiaries
  • Consider children's arrangements
  • Destroy old will completely

Cost: $400-$800 for comprehensive new will (essential investment)

Example 4: Multiple Small Changes (New Will Required)

Situation: David (59, SA) wants to update his executor's phone number, add a $5,000 gift to his nephew, and correct his daughter's married name.

Analysis:

Factor Assessment
Single change only? ✗ No, three changes
Creates complexity? ✓ Yes
Clarity concern? High

Decision: New will required

Why:

  • Multiple changes in one codicil creates confusion
  • Multiple codicils even worse
  • Three changes = significant review opportunity
  • Cost of new will similar to complex codicil

What NOT to do:

❌ WRONG: Making a codicil with multiple amendments

CODICIL TO THE WILL OF DAVID JOHN BROWN

1. I amend Clause 2 to update the phone number...
2. I add a new clause 4A to provide...
3. I amend Clause 5 to change the name from... to...

[This creates confusion and increases contest risk]

Correct approach: A new will that includes every change in one document

Example 5: Second Codicil Needed? (New Will Required)

Situation: Margaret (72, WA) made a codicil to her will 2 years ago to update her executor's address. Now she wants to make another small change, adding her great-nephew as a $10,000 beneficiary.

Analysis:

Factor Assessment
Already has codicil? ✗ Yes, one existing codicil
Change is small? ✓ Yes
"One Codicil Rule"? Applies

Decision: New will required

Why:

  • "One Codicil Rule", never have more than one codicil
  • Second codicil creates document chain problem
  • Probate complexity increases significantly
  • Contest risk multiplies with each additional document

What this would look like: If Margaret made a second codicil:

At probate, the executor must present:
1. Original Will (2018)
2. First Codicil (2022)
3. Second Codicil (2024)

Each document must be proven authentic.
Each creates additional contest opportunity.
Court costs increase with document complexity.

Better approach: New will in 2024 that:

  • Incorporates executor address change
  • Adds gift to great-nephew
  • Provides single clear document
  • Cost: $300-$500 (less than potential dispute)

Example 6: Will Over 5 Years Old (New Will Required)

Situation: Thomas (61, NT) made his will in 2017. He wants to update his superannuation beneficiary nomination in the will to include his new partner.

Analysis:

Factor Assessment
Will age? ✗ 7 years old
"5-Year Rule"? Applies
Laws may have changed? ✓ Yes
Life circumstances? ✓ Likely changed

Decision: New will required

Why:

  • Will is over 5 years old
  • Laws and circumstances likely changed
  • Adding partner suggests significant life change
  • Comprehensive review essential
  • Note: Superannuation nominations in wills don't directly bind super funds, separate binding nomination needed

Additional actions for Thomas:

  • Make new will
  • Review all beneficiaries
  • Complete new binding death benefit nomination with super fund
  • Consider partner's entitlements
  • Review all insurance policies
  • Ensure will reflects current asset position

Example 7: Blended Family Change (New Will + Professional Advice)

Situation: Amanda (55, ACT) married a widower with two adult children 3 years ago. Her will, made 5 years ago, leaves everything to her own two children. She now wants to include her stepchildren.

Analysis:

Factor Assessment
Blended family? ✓ Yes
Family provision risk? Very high
Complexity? High
Professional advice needed? ✓ Absolutely

Decision: New will with professional estate planning advice

Why codicil is dangerous:

  • Blended families are more exposed to family provision claims
  • Complex balancing of interests required
  • May need testamentary trust provisions
  • Stepchildren provisions must be carefully drafted
  • Potential conflict between spouse and children from prior relationship

Recommended approach:

  1. Consult estate planning solicitor
  2. Consider whether to:
  • Leave percentage to stepchildren
  • Create life interest for spouse
  • Use testamentary discretionary trust
  • Make specific gifts vs residue sharing
  1. Ensure binding nominations coordinate with will
  2. Consider mutual wills with new spouse (with caution)

Cost: $600-$1,500 for comprehensive blended family will (essential investment given complexity)

Summary: Quick Reference Table

Scenario Codicil OK? New Will? Professional Advice?
Address update only ✓ Optional Optional
Name spelling correction ✓ Optional Optional
Small gift to charity Caution ✓ Preferred Recommended
Change beneficiary ✗ ✓ Required Recommended
Multiple changes ✗ ✓ Required Recommended
Second codicil needed ✗ ✓ Required Recommended
Will over 5 years old ✗ ✓ Required Recommended
Post-divorce ✗ ✓ Essential Strongly recommended
Blended family ✗ ✓ Essential Essential
Business interests ✗ ✓ Essential Essential
Significant assets ($500k+) ✗ ✓ Essential Strongly recommended

Key Takeaways

Before you decide between a codicil and a new will, remember these essential points:

The Core Principles

Principle What It Means
The New Will Rule In most cases, a new will is the better choice
The One Codicil Rule Never have more than one codicil, make a new will instead
The 5-Year Rule If your will is over 5 years old, make a new will regardless of how minor the change
The Administrative Test Codicils are only appropriate for purely administrative changes (addresses, spelling)
The Distribution Test Any change affecting who gets what = new will required

When Codicils Are Appropriate (Rare)

✓ Single administrative change (address update, name spelling) ✓ First and only change to this will ✓ Will less than 5 years old ✓ Simple family situation ✓ No prior codicils

When New Wills Are Required

✗ Any change to beneficiaries or distribution ✗ Already have one or more codicils ✗ Will over 5 years old ✗ Multiple changes needed (even small ones) ✗ Major life event (divorce, marriage, children) ✗ Blended family situation ✗ Business interests or significant assets

The Hidden Cost Reality

A codicil can be cheaper to prepare, but if it creates confusion or a dispute, the legal costs are usually paid from the estate.

Bottom line: The cheapest upfront option is often the most expensive in total.

Critical Execution Requirements

Every codicil and new will must be:

  • Signed by you in the presence of two witnesses
  • Witnessed by two adults who are NOT beneficiaries (best practice)
  • Signed by both witnesses in your presence (and, as best practice, each other's presence)
  • Stored securely (ideally with original will for codicils)

After Making Changes

For Codicils:

  • Keep with the original will (e.g. in the same envelope), without stapling or clipping it to the will
  • Notify executor
  • Never add another codicil

For New Wills:

  • Include revocation clause
  • Destroy old will completely
  • Notify executor of location
  • Update will registry if registered

Legislation and Official Resources

Will-making in Australia is governed by each state and territory's own succession legislation. The core statutes include:

When to Seek Professional Help

While WillBuddy handles most straightforward will situations, we recommend consulting a solicitor if you have:

  • A blended family with potential disputes
  • Business succession requirements
  • Significant overseas assets
  • Complex trust structures
  • Likely family provision claims

This guide is general information, not legal advice. For advice about your situation, see a qualified solicitor in your state or territory.

For the one who keeps the family covered

WillBuddy writes a new will from plain questions about the family you have now, for your state. Once it's signed and witnessed, it replaces your old will, so include everything you still want. Read every word free, with no card. You pay only if you want to print it.
