Proper witnessing is essential for your will to be legally valid in Australia. A will that fails witnessing requirements can be declared invalid, causing your estate to be distributed under intestacy laws instead of your wishes. This guide explains exactly who can witness your will and the correct witnessing process across all Australian states and territories.
This article is part of WillBuddy's Knowledge Centre, created to help Australians understand will witnessing requirements across all states.
Quick Answer
Will witnesses in Australia must be at least 18 years old, have mental capacity, and cannot be beneficiaries in the will or married to a beneficiary. You need two independent witnesses who watch you sign and then sign themselves in your presence and each other's presence, all at the same time.
- Who qualifies: Adults with mental capacity who receive nothing under the will, neighbours, colleagues, or non-beneficiary family.
- All present together: You and both witnesses must be in the same room, signing in one session.
- Beneficiary-witness risk: In NSW and QLD a beneficiary-witness loses their gift, though Victoria is an exception (s11 Wills Act 1997).
- Get it wrong and: The will can be invalid or a gift voided, forcing an expensive court application under the dispensing power.
Who Can Witness Your Will?
Key point
You need two independent witnesses who are at least 18, have mental capacity, and receive nothing under the will. All three of you must sign in the same session, each in the presence of the others.
Will witnesses must meet these requirements in all Australian states:
| Requirement | Details |
|---|---|
| Age | Must be at least 18 years old |
| Mental capacity | Must understand they are witnessing a will signing |
| Independence | Cannot be a beneficiary named in the will |
| Relationship | Cannot be married to or in a de facto relationship with any beneficiary |
| Presence | Must physically see the will-maker sign (or acknowledge their signature) |
Good Witness Choices
- Neighbours or friends who are not receiving anything under your will
- Work colleagues who are not beneficiaries
- Family members who are not receiving gifts (e.g., a sibling when only your spouse and children inherit)
- Professionals such as your accountant, doctor, or bank manager
- Solicitors or justice of the peace (though not legally required)
Who Should NOT Witness Your Will
- Anyone named as a beneficiary in your will
- The spouse or de facto partner of any beneficiary
- Anyone under 18 years old
- Anyone who lacks mental capacity
- Your executor can technically witness, but it's best practice to use independent witnesses
State-by-State Witnessing Requirements
Key point
If a beneficiary witnesses the will, the outcome depends on your state. In NSW and QLD the gift to that beneficiary-witness is void, while Victoria (s11 Wills Act 1997) is an exception where the gift is not void. Using independent witnesses avoids the question everywhere.
Each state has its own succession legislation governing will execution. While requirements are similar, there are important differences:
New South Wales (Succession Act 2006)
| Requirement | NSW Rule |
|---|---|
| Number of witnesses | Two witnesses required |
| Witness presence | Both must be present at the same time |
| Beneficiary as witness | Gift to beneficiary-witness is void (s10), unless a court exception applies |
| Remote witnessing | Permanently allowed under s8A (as of 2022) with audio-visual link |
| Signature location | Must sign at the foot or end of the will |
Note: During the COVID-19 period, temporary laws in several states allowed witnessing by audio-visual link. Most of these measures have since been made permanent or replaced, so always check your state's current remote-witnessing rules.
Victoria (Wills Act 1997)
| Requirement | VIC Rule |
|---|---|
| Number of witnesses | Two witnesses required |
| Witness presence | Must witness in presence of each other and the testator |
| Beneficiary as witness | Gift to beneficiary-witness is NOT void (s11, Wills Act 1997); independent witnesses still recommended |
| Remote witnessing | Temporary COVID provisions expired; in-person generally required |
| Signature location | Should appear at the end of the will |
Key case law: Nichol v Nichol [2017] QSC 220 (applies generally) – Informal documents can be admitted under dispensing power if intention is clear.
Queensland (Succession Act 1981)
| Requirement | QLD Rule |
|---|---|
| Number of witnesses | Two witnesses required |
| Witness presence | Must witness in presence of each other and the testator |
| Beneficiary as witness | Gift to beneficiary-witness is void (s11), unless court orders otherwise |
| Remote witnessing | Temporary COVID provisions expired; check current QLD Justice guidance |
| Signature location | Signature generally at the foot/end of the will |
Key case law: Nichol v Nichol [2017] QSC 220, where the QLD Supreme Court used the dispensing power to validate an unsent text message because the deceased's intention was clear.
South Australia (Succession Act 2023)
| Requirement | SA Rule |
|---|---|
| Number of witnesses | Two witnesses required |
| Witness presence | Must witness in presence of each other and the testator |
| Beneficiary as witness | Gift to beneficiary-witness is NOT void (s13, Succession Act 2023); independent witnesses still recommended |
| Remote witnessing | Rules vary and change over time; check current state rules |

The Correct Witnessing Process: Step-by-Step
Follow this exact process to ensure your will is properly witnessed:
Step 1: Prepare the Document
- Print your completed will (do not sign yet)
- Ensure all pages are numbered (e.g., "Page 1 of 4")
- Have both witnesses present with you
Step 2: Sign in the Presence of Both Witnesses
- Sign the will at the end while both witnesses watch
- Use your normal signature (the one on official documents)
- Sign in permanent ink (black or blue recommended)
Step 3: Witnesses Sign Immediately After
- Each witness signs the will immediately after you
- They must sign in your presence and in each other's presence
- Witnesses should print their name, address, and occupation below their signature
Step 4: Initial Each Page (Recommended)
- You and both witnesses initial each page in the margin
- This is not legally required but prevents disputes about missing pages
Step 5: Store Safely
- Keep the original will in a secure, fireproof location
- Tell your executor where it is stored
- Never staple, clip, or bind additional documents to the executed will
What Happens If Witnessing Requirements Are Not Met?
| Problem | Consequence | Can It Be Fixed? |
|---|---|---|
| Only one witness | Will is invalid | Courts may admit under dispensing power if intention is clear |
| Beneficiary witnessed | Their gift is void (but will is otherwise valid) | Court may grant relief in some states |
| Witnesses not present together | Will may be invalid | Depends on substantial compliance; may require court application |
| Signature not at end of will | May affect validity | Courts look at intent; position matters less if clear intention |
| Witnesses signed on different days | Will likely invalid | Strong evidence of intent needed for dispensing power |
The Dispensing Power
All Australian states have a "dispensing power" allowing courts to admit documents that don't strictly comply with execution requirements if there is clear evidence of testamentary intention. However, this involves:
- Expensive court applications (often $5,000–$20,000+)
- Delays of 6–12 months or more
- No guarantee of success
Bottom line: Proper witnessing from the start avoids these complications entirely.
Witness Capacity: Who Genuinely Qualifies to Attest
Key point
A valid witness must be an adult of sound mind who can actually see and confirm the will-maker putting pen to paper. A beneficiary (or their spouse or partner) should never witness, and an executor who inherits nothing under the will can witness, though independent witnesses remain the safer choice.
The age and capacity rules in the table above set the floor, but it helps to understand the practical reasoning behind them. A witness is not just a spare signature on the page. Their job is to be able to swear, if ever asked, that they saw the will-maker sign the document freely and willingly. That single function explains who can and cannot do the job.
Adults with mental capacity: A witness must understand what they are doing, namely watching someone sign a will. Someone who is heavily intoxicated, seriously cognitively impaired, or too young to grasp the occasion cannot give that confirmation reliably, which is why the law requires an adult of sound mind.
Not a beneficiary, and not a beneficiary's spouse or partner: Because a witness is meant to be neutral, a person who stands to gain under the will is the wrong choice. In most states a gift to a beneficiary who witnesses (or whose husband, wife, or de facto partner witnesses) is voided, even though the rest of the will survives. Victoria and South Australia are the well-known exceptions, but the safe rule everywhere is simply to keep beneficiaries and their partners away from the witness line.
An executor who is not a beneficiary can witness: Being named as executor does not, by itself, give a person any gift under the will. So an executor who receives nothing can validly witness. That said, using genuinely independent witnesses removes any later argument about influence, so it is still the better practice.
A person who cannot see the signing cannot witness: A witness has to actually observe the will-maker sign or acknowledge the signature. A blind person cannot perform that role, because they cannot attest to seeing the pen meet the page, no matter how willing or capable they otherwise are.

The Signing Ceremony, and Why Strict Compliance Beats the Court
Key point
Treat the signing as one short ceremony: the will-maker and both witnesses together at the same table, the will-maker signing or acknowledging first, then each witness signing while everyone watches. Getting this right the first time is far cheaper and more certain than asking a court to rescue an informal will later.
The earlier step list tells you what to do. This section explains the order and the logic so nothing goes wrong on the day.
Run it as a single occasion
The cleanest signing happens as one continuous event with all three people in the same room from start to finish:
Everyone is present before anyone signs. The will-maker and both witnesses gather together. Nobody steps out until all signatures are complete.
The will-maker signs or acknowledges first. The will-maker either signs the will in front of both witnesses, or, if already signed, clearly acknowledges to both witnesses that the signature on the page is theirs. Both witnesses must see this happen.
Both witnesses then sign in the will-maker's presence and each other's presence. After the will-maker, each witness signs while the will-maker and the other witness watch. The witnesses do not need to read the will or know its contents. They are confirming the act of signing, not the gifts inside.
Use the same pen and the same sitting, and date it. Signing with one pen in one session, and dating the will on the day, makes it obvious that everyone signed together. Splitting the signing across rooms, days, or pens is exactly what creates later doubt.
Why strict compliance is worth the small effort
Every Australian state gives its court a dispensing power, a discretion to admit a document that does not strictly meet the execution rules when there is clear proof the person intended it to be their will. It is a genuine safety net, but it is a poor substitute for doing things properly:
It is not automatic. The court has to be persuaded, with evidence, that the document really was meant to be the will. There is no guarantee it will agree.
It is slow and costly. Rather than a simple grant of probate, the estate faces a contested-style application, with legal fees and delay falling on the very people the will-maker wanted to help.
Strict compliance sidesteps all of it. A will signed and witnessed correctly the first time needs no rescue. The few minutes spent getting the ceremony right are the cheapest insurance in estate planning.
In short, the dispensing power exists for emergencies, not as a plan. A properly witnessed will keeps your estate out of the courtroom and gives your executor a clean document to act on. For the steps that follow signing, see how to update or change a will.
Common Witnessing Mistakes That Invalidate Wills
Mistake 1: Beneficiary Acting as Witness
The problem: A son who inherits half the estate witnesses his mother's will. The consequence: The son's gift is void, he receives nothing. The will otherwise remains valid. How to avoid: Only use witnesses who receive nothing under the will.
Mistake 2: Witnesses Not Present Together
The problem: Wife signs will, Witness 1 signs immediately, but Witness 2 signs the next day. The consequence: The will may be invalid, all three signatures must occur together. How to avoid: Complete all signing in one session with everyone present.
Mistake 3: Signing Before the Will is Finalised
The problem: Will-maker signs a draft, then makes changes and doesn't re-sign. The consequence: The executed version doesn't reflect final intentions; changes may be ignored. How to avoid: Only sign the final, complete version of your will.
Mistake 4: Writing on the Will After Execution
The problem: Will-maker crosses out a gift or writes a note after signing. The consequence: Alterations made after signing are not valid unless separately witnessed. How to avoid: Make changes through a codicil or new will with fresh witnessing.
Frequently Asked Questions
Can my executor also witness my will?
Technically yes, executors who are not also beneficiaries can witness. However, best practice is to use completely independent witnesses to avoid any perception of undue influence.
What if I can't find two suitable witnesses?
Consider: neighbours, work colleagues, professionals you deal with (accountant, doctor, bank manager), or family members not receiving gifts. Libraries, post offices, and community centres sometimes offer witnessing services.
Do witnesses need to read my will?
No. Witnesses only need to see you sign and confirm they are witnessing your signature on a will. They do not need to read the contents.
Can witnesses be overseas or interstate?
Witnesses must be physically present when you sign. If you relocate, you may need to find new witnesses or travel to execute your will.
