This article is part of WillBuddy's Knowledge Centre, created to help Australians understand divorce and separation impacts on wills.

Quick Answer

In Australia, divorce automatically affects your will but separation does not. After divorce, gifts to your ex-spouse and their appointments as executor, trustee, or guardian are revoked, while the rest of your will stays valid.

  • Separation = no change: Your current will continues unchanged on separation, so a separated spouse can still inherit everything until you make a new will.
  • Divorce revokes ex-spouse provisions: Gifts to your former spouse are treated as if they predeceased you, and the remainder of the will remains operative.
  • Super isn't automatic: Divorce does not change your binding super nomination or life insurance, you must update these yourself.
  • Act immediately: Make a new will on day one of separation and review powers of attorney and beneficiary nominations.

Divorce vs Separation: Critical Differences

Key point

Divorce automatically affects your will (gifts and appointments to your ex-spouse are revoked), but separation has no automatic effect, so a separated spouse can still inherit everything until you make a new will.

The most important distinction in estate planning:

Event Effect on Will Effect on Super Effect on Property
Separation ❌ NO automatic effect ❌ NO automatic effect ❌ NO automatic effect
Divorce ✅ Affects ex-spouse provisions ❌ NO automatic effect May trigger property settlement
Death of spouse ❌ Will remains valid Paid per nomination Passes per will/intestacy

Critical warning: Separation does NOT change your will. If you separate but don't make a new will, your separated spouse could still inherit your entire estate.

How Divorce Affects Your Will

Automatic Changes After Divorce

When your divorce becomes final (not when you separate), these changes occur automatically by law:

Provision Effect After Divorce
Gifts to ex-spouse Treated as if ex-spouse predeceased you (gift fails)
Ex-spouse as executor Appointment revoked
Ex-spouse as trustee Appointment revoked
Ex-spouse as guardian Appointment revoked
Gifts to ex-spouse's relatives Usually remain valid (state-dependent)
Rest of will Remains valid and operative

What Happens to Failed Gifts?

When a gift to your ex-spouse fails, it typically:

  1. Passes to substitute beneficiary (if named in your will)
  2. Falls into residue (if no substitute named)
  3. Passes by intestacy (if it was the residuary gift)

Example: Your will leaves "my home to my spouse, or if they predecease me, to my children equally." After divorce, the gift to your ex-spouse fails, but your children inherit the home as substitute beneficiaries.

State-by-State Legislation

New South Wales

Aspect NSW Rules
Legislation Succession Act 2006 (NSW), s13
Divorce effect Ex-spouse treated as having predeceased
Separation effect No automatic effect
De facto separation No automatic effect
Family provision claims Ex-spouse eligible under s57
Claim time limit 12 months from death

Key point: Even where divorce revokes gifts to a former spouse, that ex-spouse may still qualify as an eligible person to bring a family provision claim against the estate, so divorce does not always end their potential interest.

Victoria

Aspect VIC Rules
Legislation Wills Act 1997 (Vic), s14
Divorce effect Ex-spouse's appointments and gifts revoked
Separation effect No automatic effect
De facto separation No automatic effect
Family provision claims Ex-spouse eligible under Part IV Administration and Probate Act 1958
Claim time limit 6 months from grant of probate

Queensland

Aspect QLD Rules
Legislation Succession Act 1981 (Qld), s15
Divorce effect Ex-spouse treated as having predeceased
Separation effect No automatic effect
De facto separation No automatic effect
Family provision claims Ex-spouse eligible under Part 4
Claim time limit 9 months from death (6 months from grant if later)

Other States

State Legislation Divorce Effect
Western Australia Wills Act 1970 (WA), s14A Ex-spouse provisions revoked
South Australia Succession Act 2023 (SA) Ex-spouse provisions revoked
Tasmania Wills Act 2008 (Tas), s17 Ex-spouse provisions revoked
ACT Wills Act 1968 (ACT), s20A Ex-spouse provisions revoked
Northern Territory Wills Act 2000 (NT), s15 Ex-spouse provisions revoked

Separation: Why Immediate Action is Essential

Key point

During separation, your current will remains fully valid and all gifts to your spouse still take effect, so make a new will on Day 1 of separation.

The Separation Risk

During separation (before divorce is finalised):

  • Your current will remains fully valid
  • All gifts to your spouse will take effect if you die
  • Your spouse may still be your executor
  • Intestacy rules favour your spouse if you have no will

Separation Timeline

Period Risk Level Action Required
Day 1 of separation HIGH Make new will immediately
First 12 months HIGH Review all estate planning documents
Property settlement MEDIUM Update will to reflect new assets
Divorce finalised LOWER Automatic revocation takes effect
Post-divorce ONGOING Make new will reflecting final situation

Case Study: The Separation Risk

John and Mary separated after 20 years of marriage. John intended to update his will but died in a car accident 6 months later, before their divorce was finalised. His will left everything to Mary. Because they were only separated, not divorced, Mary inherited John's entire $800,000 estate, despite John having told his children he intended to leave them his assets.

Lesson: Make a new will on Day 1 of separation.

Superannuation and Life Insurance

Superannuation Death Benefit Nominations

Critical: Divorce does NOT automatically change your super beneficiary nominations.

Nomination Type Effect After Divorce
Binding nomination Remains valid, ex-spouse will receive benefits
Non-binding nomination Trustee has discretion, may consider current situation
Reversionary pension Remains valid unless specifically changed
No nomination Trustee decides based on dependants and legal representatives

Steps to Update Superannuation

  1. Contact your super fund(s) immediately
  2. Request new nomination forms
  3. Complete new binding death benefit nominations
  4. Name your intended beneficiaries (children, estate, new partner)
  5. Ensure nominations are valid and witnessed
  6. Confirm receipt with your super fund

Life Insurance

Policy Type Divorce Effect
Policy owned by you, ex-spouse beneficiary No automatic change, update required
Policy owned through super Follows super nomination rules
Policy owned by ex-spouse on your life Ex-spouse retains ownership and benefits
Joint policy May need to be split or cancelled

Property Settlement Considerations

Property Settlement and Your Will

Property settlements during divorce affect what assets you have to leave:

Situation Estate Planning Action
Pending settlement Make interim will covering current assets
Settlement complete Make final will reflecting new asset position
Superannuation split Update nominations for remaining balance
Business interests divided Update business succession planning
Family home transferred Update will accordingly

Binding Financial Agreements (BFAs)

Binding Financial Agreements (often called "prenups" or "postnups") can affect estate claims:

BFA Type Effect on Estate Claims
Pre-marriage BFA May limit ex-spouse's family provision claims
During marriage BFA May define property division and limit claims
Separation BFA May finalise entitlements and bar claims
No BFA Ex-spouse retains full right to claim

Note: Even with a BFA, courts can set them aside in certain circumstances. Legal advice is essential.

Family Provision Claims by Ex-Spouses

Can My Ex-Spouse Claim Against My Estate?

Yes. In all Australian states, a former spouse can make a family provision claim if:

  • They demonstrate financial need
  • The will doesn't make adequate provision for them
  • They file within the time limit

Factors Courts Consider

Factor Relevance
Length of marriage Longer marriages may strengthen claims
Financial contributions What did each party contribute?
Current financial position Does ex-spouse have need?
Property settlement Was there a fair settlement?
Other beneficiaries' needs Competing claims from children etc.
Testator's reasons Why was ex-spouse excluded?
Time since divorce Generally weakens over time

Reducing Claim Risk

Strategy How It Helps
Complete property settlement Fair settlement reduces need-based claims
Binding Financial Agreement May bar or limit claims
Document reasons Explain your distribution rationale
Small specific gift Acknowledge the relationship
Professional drafting Ensure will is defensible

De Facto Relationships

Separation from De Facto Partner

De facto separation has the same effect as married separation, NO automatic change to your will.

Situation Your Will
De facto relationship ends Will remains unchanged
De facto partner still named They inherit as per will
De facto partner was executor They remain executor

De Facto Partner's Rights

State De Facto Recognition for Family Provision
NSW 2 years cohabitation or child together
VIC 2 years cohabitation (registered or unregistered)
QLD 2 years cohabitation or child together
WA 2 years cohabitation
SA 3 years cohabitation or child together

Blended Family Estate Planning

After Divorce: New Relationships

When you form a new relationship after divorce, estate planning becomes complex:

Consideration Planning Strategy
Current partner vs ex-partner Clearly define who receives what
Children from first marriage Testamentary trusts protect their interests
Children from new relationship Equal or different treatment?
Step-children No automatic inheritance rights, must be named
New partner's children Consider mutual wills or binding agreements

Testamentary Trust Strategies

Structure How It Works
Life interest trust New spouse can live in/use asset, then passes to children
Income trust New spouse receives income, capital to children
Discretionary trust Trustee decides distributions among beneficiaries
Protective trust Protects vulnerable beneficiaries

Example: Life Interest for New Spouse

"I give my home to my Trustees to hold on trust to allow my spouse [Name] to live in the property during their lifetime, and upon their death or earlier departure, to distribute to my children [Names] in equal shares."

This balances providing for a new spouse while protecting children's inheritance.

Powers of Attorney and Guardianship

Enduring Powers of Attorney

Divorce may affect your powers of attorney differently than your will:

Document Effect of Divorce (NSW) Effect of Separation
Enduring Power of Attorney Not automatically revoked Not affected
Appointment of Enduring Guardian Not automatically revoked Not affected

Action required: Revoke existing powers and appoint new attorneys/guardians.

Steps to Update Powers of Attorney

  1. Make new Enduring Power of Attorney appointing trusted person
  2. Make new Appointment of Enduring Guardian
  3. Formally revoke old documents
  4. Notify relevant institutions
  5. Provide copies to new attorneys

Executor Considerations After Divorce

Choosing a New Executor

Your ex-spouse's appointment as executor is automatically revoked by divorce. Consider:

Option Pros Cons
Adult child Knows family, no cost May have conflicts with siblings
Trusted friend Neutral, capable May predecease you
Professional executor Expert, impartial Fees 1%–5% of estate
Public Trustee Government backed, impartial Can be slow, fees apply
Co-executors Checks and balances May disagree

Avoiding Executor Conflicts in Blended Families

  • Consider a professional executor for neutrality
  • Appoint co-executors (e.g., one child from each relationship)
  • Provide detailed guidance in your will and letter of wishes
  • Consider separate executors for different assets

Common Mistakes to Avoid

Mistake 1: Assuming Separation Changes Your Will

Problem: Your separated spouse can still inherit everything. Solution: Make a new will immediately upon separation.

Mistake 2: Forgetting Superannuation

Problem: Super can be your largest asset and isn't affected by divorce. Solution: Update nominations with every super fund.

Mistake 3: Not Updating Powers of Attorney

Problem: Ex-spouse may still make decisions for you if incapacitated. Solution: Revoke old powers and appoint new attorneys.

Mistake 4: Ignoring Family Provision Claim Risk

Problem: Ex-spouse can challenge your will. Solution: Complete fair property settlement, consider BFA, document reasons.

Mistake 5: Forgetting Step-Children

Problem: Step-children have no automatic inheritance rights. Solution: Specifically name them if you want them to inherit.
