Almost any competent adult can witness a will. Your witnesses do not need to be lawyers, they do not need to be justices of the peace, and they do not need to read a word of what they are signing. What they must not be is someone who inherits from you — and that single mistake is one of the most common reasons Australian wills end up in front of a court.
This is the part almost everyone misunderstands, and understanding it makes every other rule obvious.
A witness to a will is confirming one narrow fact: that they personally watched you sign this document. That is the whole job. They are not confirming that they agree with your decisions. They are not confirming that they understand what the document says. They are not confirming that your wishes are sensible, or fair, or legally effective. They are certainly not confirming that they know who inherits.
They are eyewitnesses to an event. Nothing more.
Once you see witnessing that way, the rules stop feeling arbitrary. A witness must be able to see you sign, so they must be able to see. A witness may one day have to give evidence about what they saw, so they should be an adult of sound mind who can be found later. And a witness must be believable when they say the signing was free and voluntary — which is exactly why someone who stands to gain from the will is the wrong choice.
The bar is genuinely low. A valid witness needs to be:
Notice what is not on that list. No professional qualification. No relationship test. No citizenship or residency requirement. No fee.
There is really one serious prohibition, and then a short list of poor choices.
This is the big one, and it is where Australia splits into two camps.
In New South Wales, Queensland, Tasmania and the Northern Territory, a gift to someone who witnessed the will is void by default. The will itself usually survives — but the gift to that witness fails, and the property falls into the rest of the estate. There are limited saving provisions: typically that at least two other witnesses were not beneficiaries, that everyone who would benefit from the gift failing consents in writing, or that the court is satisfied the will-maker knew about and freely approved the gift. Those are escape hatches, not a plan.
In Victoria, South Australia, Western Australia and the Australian Capital Territory, that rule has been abolished. A gift to a witness stands, and the witness keeps their inheritance.
So does that mean it is safe in half the country? No — and this is the point most articles miss. Abolishing the automatic voiding rule removed a technical trap. It did not remove the evidential one. If the person who stood over you while you signed is also the person who did unusually well out of the document, you have handed a disappointed relative the easiest undue-influence argument available. The gift is not automatically void; it is merely contestable, at the estate's expense.
The practical rule is the same in all eight jurisdictions: do not let a beneficiary witness your will. Check your own state's consequence on the state pages if you want the specific provision.
Several jurisdictions extend the interested-witness rule to a beneficiary's husband, wife or domestic partner. Even where they do not, the same evidential problem applies. If your son inherits the house, do not use your daughter-in-law as a witness.
Legally, they usually can. Practically, do not. Your spouse or partner is nearly always a beneficiary, which drops you straight back into the problem above. This is such a common instinct — the person nearest to you when you sign — that it is worth stating plainly: use someone who inherits nothing.
Slightly different, and more nuanced. An executor who receives no gift under the will is generally not an "interested" witness, because appointment as executor is an office rather than an inheritance. Many wills are validly witnessed by an executor. But if your executor also inherits — which is very common, since people often appoint the adult child who is also a main beneficiary — then they are a beneficiary, and the rule bites.
If you cannot sign yourself and direct another person to sign for you, that person is performing your signature. They should not also be one of your witnesses.
There is a persistent myth that family members cannot witness a will. There is no such rule anywhere in Australia. A brother, an adult grandchild, a cousin, a parent — all can witness a will perfectly validly.
The confusion arises because family members are so often beneficiaries. It is not the blood relationship that causes the problem, it is the inheritance. A nephew who gets nothing under the will is an unremarkable witness. A nephew who gets $50,000 is a problem.
The cleanest approach, and the one we recommend to everyone: pick two people who have no possible interest in your estate. Two neighbours. Two colleagues. Two friends from the golf club. It removes every argument at once.
Worth being explicit, because these misconceptions cause real anxiety:
Australia has no requirement for a will to be notarised, and there is no register you must lodge it with. This trips up people who have seen American films, or who have lived in a civil-law country where a notary is central to estate planning.
You do not need a justice of the peace. You do not need a stamp. You do not need to file the will with a court while you are alive. A will that is in writing, signed by you, and witnessed by two adults who watched you sign, is a valid will — whether it was prepared by a top-tier firm or written at your kitchen table.
Some state trustees offer will storage, and some people leave the original with their solicitor. That is about safekeeping, not validity. What matters legally is that the original signed document can be found after your death.
No. There is no legal requirement anywhere in Australia for a solicitor to be present when a will is signed. Two independent adult witnesses is what the law asks for.
A solicitor's real value is upstream of the signing: working out whether what you have written actually achieves what you intend, spotting that your superannuation will not pass under the will at all, noticing that leaving "the house" to one child and "the savings" to another will end in a fight when the house triples in value. That is judgement work. Watching you sign is not.
This is exactly the gap eQUILL is built for. You answer plain-English questions, the document is prepared properly, and it is reviewed by an Australian solicitor before it comes back to you — for $139 once, with no subscription. Then you sign it in front of two witnesses, at your own kitchen table, on your own schedule.
Everything above is the same across Australia. Three things are not, and they are worth checking for your own state:
Pick your state on the wills by state hub for the specific provisions, section numbers and consequences. If you want the mechanics of the signing itself — order, pages, dates, changes — that is covered in how to sign a will correctly.
No. Your witnesses do not need to read a single word of your will, and you are entitled to keep its contents completely private from them. A witness is confirming one narrow fact: that they watched you sign this document. They are not confirming that they agree with it, that they understand it, or that they know who inherits.
Yes. There is no rule anywhere in Australia against a relative witnessing your will. A sibling, adult child, cousin or parent can all witness perfectly validly. The problem is not the relationship, it is the inheritance. If that relative is also receiving something under the will, they should not witness it.
Avoid it. In New South Wales, Queensland, Tasmania and the Northern Territory a gift to a person who witnessed the will is void by default, subject to limited saving provisions. In Victoria, South Australia, Western Australia and the ACT that rule has been abolished and the gift stands. But even where the gift survives, a beneficiary witness invites a challenge on the basis of undue influence.
Legally they usually can, but practically you should not let them. Your spouse or partner is almost always a beneficiary, which puts you straight into the interested witness problem. Use two neighbours, two colleagues or two friends who inherit nothing.
No. There is no register you must lodge your will with, and it does not need a notary, a justice of the peace or a stamp to be valid. Australia has no requirement for a will to be notarised. What makes a will valid is that it is in writing, signed by you, and witnessed correctly.
No. There is no legal requirement for a solicitor to be present at the signing of a will anywhere in Australia. Two independent adult witnesses are what the law asks for. A solicitor adds value in reviewing whether the will does what you intend, not in watching you sign it.
A witness should be at least 18. The legislation is generally framed around competence rather than a fixed witness age, but a witness may one day need to give evidence about the signing, and a court will treat an adult witness as far more reliable. Never use a child.
No. A witness must be able to see you sign, because that is the entire substance of what they are attesting to. A person who cannot see the signature being made cannot perform the function the law requires of a witness.
