Contesting a Will in Australia: Family Provision Claims Explained

Nothing divides a family quite like a will. The funeral is barely over, the document is read, and someone discovers they have been left out, left short, or left a pointed token while a sibling takes the house. Grief curdles into grievance with remarkable speed, and the question arrives at a lawyer's desk — or, increasingly, a search bar — in the same words almost every time: can I contest this?

In Australia, more often than people expect, the answer is yes. Every state and territory has family provision legislation that lets a court override a will — not because the will is forged or the testator lacked capacity, but simply because it fails to make adequate provision for someone the deceased ought to have provided for. This is the workhorse of Australian estate litigation. Genuine validity challenges — dementia, undue influence, a suspicious second will — are comparatively rare. Family provision claims are filed in large numbers every year, and the great majority of them settle at mediation before a judge ever hears evidence.

This guide explains the difference between attacking a will's validity and claiming provision from a valid one, who is eligible to claim, the strict and state-specific time limits, what courts actually weigh, the New South Wales rules that reach assets given away before death, and the costs realities that both claimants and executors misunderstand — usually in opposite directions.

Two different fights: validity and provision

People say "contesting a will" to mean two legally distinct things, and the distinction controls everything that follows.

A validity challenge says the document is not the deceased's true will at all. The classic grounds are lack of testamentary capacity — the test still traces to Banks v Goodfellow (1870) LR 5 QB 549, which asks in substance whether the testator understood what a will does, what they owned, and who had claims on them, free of a disorder of the mind poisoning those judgments — together with undue influence, lack of knowledge and approval of the will's contents, improper execution, and outright forgery. If a validity challenge succeeds, the will falls entirely, and the estate passes under an earlier valid will or under the intestacy rules. These are probate proceedings: evidence-heavy, expensive, and hard to win, because the law presumes a rational-looking, duly executed will is valid. If your real complaint is that the will is unfair rather than not genuine, a validity challenge is usually the wrong tool.

A family provision claim concedes that the will is valid and says something different: that it fails to make adequate provision for the claimant's proper maintenance, education and advancement in life. The court is given a statutory power to order provision out of the estate despite what the will says. It is not a fairness audit and it does not rewrite the will wholesale — but it is a genuine judicial override of the testator's wishes, and it is the main way wills are contested in Australia. The rest of this article is about these claims.

Who can claim: eligibility varies by state

Family provision is state law, and each state and territory defines its own list of eligible applicants. The common core is everywhere the same: a spouse, a de facto partner, and the deceased's children can apply in every Australian jurisdiction. Beyond that core, the lists diverge.

In New South Wales, the Succession Act 2006 (NSW) extends eligibility to former spouses, to persons who were wholly or partly dependent on the deceased and were either grandchildren or members of the deceased's household at some point, and to a person who was living in a close personal relationship with the deceased at death. Some of these additional categories must also persuade the court that there are factors warranting the making of the application at all — an extra threshold the core categories do not face.

Victoria runs a tighter regime. Amendments to the Administration and Probate Act 1958 (Vic) that commenced in 2015 replaced a broad "responsibility" test with a defined list of eligible persons — spouses and domestic partners, children and stepchildren, certain former spouses, registered caring partners, and certain grandchildren and household members — with several categories required to show dependency on the deceased. The reform was a deliberate legislative brake on speculative claims.

Two practical points follow. First, eligibility is a threshold, not a victory: being on the list gets you through the door, nothing more. Second, never assume your state's list from an article about another state — a carer eligible in one jurisdiction may have no standing across the border.

The clock: strict, and different in every state

Family provision time limits are short, they differ by state, and — the trap — they do not all run from the same event.

New South Wales: an application must be made within 12 months of the date of death under the Succession Act 2006 (NSW).
Victoria: the application must be made within six months of the grant of probate (or letters of administration) under the Administration and Probate Act 1958 (Vic).
Elsewhere: the other states and territories each set their own period — some running from death, some from the grant, some shorter than six months, and some pairing the filing deadline with an even earlier expectation of written notice to the executor. Check the current rule for your state before you do anything else.

Courts have power to extend time, but the discretion is real, not routine: you must explain the delay, and an extension becomes progressively harder — and eventually pointless — once the estate has been lawfully distributed. An executor who distributes after the limitation period has expired, without notice of any claim, is generally protected, and the assets are gone.

The practical move for any would-be claimant is simple and free: put the executor on written notice immediately. An executor with notice of an intended claim distributes at their own risk, so early notice effectively freezes the estate while you take advice. Silence, by contrast, lets the clock and the distribution both run against you.

What the court actually weighs

The High Court's decision in Singer v Berghouse (1994) 181 CLR 201 established the two-stage approach that still frames every claim. First, was the provision made for the applicant (which may be nothing) inadequate for their proper maintenance, education and advancement in life, judged against their financial position, the size of the estate, and the competing claims on it? Second, if so, what provision ought now to be made? In Vigolo v Bostin (2005) 221 CLR 191 the High Court revisited the older language of "moral duty" and "moral claims" — useful shorthand, the judges variously thought, but the statutory question remains adequacy of provision, not a free-floating inquiry into what a good parent would have done.

In practice, courts weigh a familiar cluster of factors:

Need. The applicant's financial resources, earning capacity, age, health and obligations — including those of anyone they support. Need is the engine of most successful claims.
The size and nature of the estate. A large estate can accommodate generosity; a small one concentrates the competition. Claims against modest estates fail more often, and cost more than they recover.
The relationship. Its length, closeness and character. Estrangement matters but does not automatically defeat a claim — courts regularly ask who caused the rift and whether the deceased's response to it was disproportionate.
Contributions. Work in a family business, care in the final years, money put into the house — contributions to the estate or to the deceased's welfare strengthen a claim.
Conduct. Disentitling conduct by the applicant can reduce or defeat provision, though the bar is high.
Competing claimants. Every dollar ordered for the applicant comes from someone else the deceased chose. The beneficiaries' own needs and claims are weighed, not ignored.
Provision already made. Lifetime gifts, the family home transferred years earlier, superannuation nominated directly — what the applicant already received counts.

Two recurring scenarios deserve a note. Adult, able-bodied children face a harder road than widows or minor children, but "harder" is not "hopeless" — need, contribution and a modest estate share can still ground an award. And a testator's written explanation for excluding someone is admissible and considered, but it is not a veto: a will-maker cannot legislate their way out of the statute by reciting reasons.

Notional estate: the New South Wales long arm

Ordinarily a family provision order can only reach assets actually in the estate at death. That creates an obvious avoidance strategy: give everything away first, or hold it in forms that pass outside the will. In most of Australia, that strategy substantially works.

New South Wales is the exception. Its notional estate provisions in the Succession Act 2006 (NSW) allow the court to designate certain property that has left the estate — or never formed part of it — as notional estate, and to make provision orders against it. Broadly, the regime can reach transactions entered into within three years of death with the relevant intention of defeating a provision claim, transactions within a year of death made while the deceased had a moral obligation to make provision and without full consideration, and transactions taking effect on death itself — which is how jointly held property passing by survivorship and superannuation death benefits paid outside the estate can be pulled back within reach.

The consequence is stark: in New South Wales, an estate emptied before death is not necessarily safe from a claim; everywhere else in Australia, it very largely is. This single difference drives real behaviour in estate planning, and it is the first thing to check when an estate looks suspiciously thin.

Mediation: where most claims actually end

Family provision litigation has a distinctive shape: almost every claim passes through court-ordered mediation, and most never come out the other side. In New South Wales the Supreme Court's standard case management of family provision claims sends them to mediation as a matter of course, and the other states follow the same pattern in substance. Judges know these cases are ruinous to run and corrosive to families, and the process is built to settle them.

Settlement rates are high for structural reasons. Both sides face genuine risk, because the discretionary, multi-factor test makes outcomes hard to predict. Costs accumulate against a fixed and often modest asset pool, so every month of litigation shrinks the thing being fought over. Executors have a practical duty to compromise sensibly. And the parties are usually relatives who will attend the same weddings and funerals for decades.

Approach mediation as the main event, not a box to tick: prepare your evidence of need or of competing claims as if for trial, and make and respond to offers seriously — a well-judged written settlement offer, made on the correct without prejudice basis, can transform the costs position later if the matter does fight on. Our guide to without prejudice communications explains how those protections and exceptions work.

Costs: the myth that the estate always pays

The most dangerous sentence in this field is "the estate pays the costs anyway." It was once close to true, and it is now reliably false.

The old indulgence — that a family provision claimant would get costs out of the estate win or lose, because the testator's own dispositions invited the litigation — has been deliberately dismantled. The modern position is that costs follow the ordinary rules: a successful claimant will usually recover costs from the estate, but an unsuccessful claimant can expect to bear their own costs and faces a real risk of being ordered to pay the estate's as well. Courts have grown pointedly intolerant of disproportionate claims against small estates, and case management in some jurisdictions includes costs-capping tools for exactly that scenario. The general machinery is the same as in any civil litigation — see our guide to costs orders — and it cuts both ways: an executor who defends unreasonably can be exposed personally too.

The proportionality arithmetic should be done before filing, not after. A claim seeking a modest additional share of a small estate can be economically irrational even if it is legally respectable: legal costs on both sides come out of the same pool the claimant is trying to enlarge.

If you are the executor

A provision claim, or a credible threat of one, changes an executor's job immediately.

Do not distribute. Once on notice of a claim or intended claim — and in any event within the limitation period — distribution is at your personal risk. Hold the estate until the position is resolved.
Understand your role. In a family provision claim the executor's duty is to uphold the will and represent the interests of the beneficiaries taking under it — but that duty includes compromising sensibly where the claim has substance. Fighting to the last dollar of a small estate is not fidelity to the testator; it is a breach of practical duty that costs orders can punish.
Disclose properly. The court will expect a full and frank account of the estate's assets and liabilities. Attempting to starve the claimant of information prolongs the case and antagonises the judge.
Gather the evidence that matters. The testator's reasons for the dispositions, any lifetime provision made for the claimant, the competing needs of the beneficiaries, and the true state of the relationship — these are the defence.
Take advice early and mediate seriously. An early, well-pitched offer is often the cheapest loyalty to the will that an executor can show.

Practical guidance for claimants

If you believe a will has left you without adequate provision, sequence your first steps in this order. Confirm you are an eligible person under the statute of the state where the deceased lived and the assets sit. Diarise the time limit — from death in New South Wales, from the grant in Victoria, and check locally elsewhere — and treat it as immovable. Notify the executor in writing at once, so the estate cannot be quietly distributed. Then assemble the evidence that actually decides these cases: a sober picture of your financial position and needs, your relationship with the deceased, and anything you contributed to their assets or care. Be honest with yourself about estate size, competing claims and proportionality. Many strong claims resolve with a single well-supported letter and a mediation; the self-represented can and do run them, and our guide to representing yourself in court covers the general discipline involved.

Above all, keep the two fights distinct in your own thinking. If the will is a fraud or the product of a failing mind, that is a validity challenge with its own rules and its own proof. If the will is real but wrong — if it simply failed to do what the law says a will-maker in that position ought to have done — then family provision is the remedy, the clock is already running, and the sooner the executor knows you are coming, the more of the estate there will be left to argue about.
