Contesting a will in NSW is the legal process of applying to a court to vary how a deceased person’s estate is distributed, and only an eligible person can do it. Under the Succession Act 2006 (NSW), this process is formally known as a family provision claim, and it is not about whether a will is fair in a general sense. It is about whether the deceased made adequate provision for your proper maintenance, education, or advancement in life. The Supreme Court of NSW has jurisdiction over these claims, and a strict 12-month deadline from the date of death applies. If you are considering contesting a will in NSW, understanding your eligibility and acting promptly are the two most critical steps.
How to contest a will in NSW: who qualifies as an eligible person?
Eligibility under section 57 of the Succession Act 2006 (NSW) is the mandatory gateway to any family provision claim. Without it, no claim can proceed, regardless of how unfair the will may appear. Practitioners consistently emphasise that early eligibility evaluation avoids wasted effort on evidence gathering before the threshold question is even answered.
The categories of eligible persons under section 57 are:
- Spouse or de facto partner of the deceased at the time of death
- Children of the deceased, including adopted children and, in some circumstances, stepchildren
- Former spouses or former de facto partners
- Grandchildren who were wholly or partly dependent on the deceased
- Members of the household who were wholly or partly dependent on the deceased
- Persons in a close personal relationship with the deceased at the time of death
Conditional eligibility applies to stepchildren, former partners, and persons in close personal relationships. These claimants must demonstrate additional facts, such as dependency or the nature of the relationship, before the court will treat them as eligible. Estranged family members face particular scrutiny, as courts weigh the quality and duration of the relationship against the claim.
Pro Tip: If you are unsure whether you qualify, do not assume you do not. Stepchildren and long-term household members are frequently surprised to learn they have standing. Get a legal assessment before ruling yourself out.
What are the time limits to contest a will in NSW?
The 12-month deadline from the date of death is the single most important procedural fact in any NSW will dispute. This deadline comes from section 58(2) of the Succession Act 2006 and does not run from when you discovered the will, when probate was granted, or when you first sought legal advice. It runs from the day the deceased died.
The court holds a discretion to allow late applications where an applicant demonstrates “sufficient cause,” but extensions are genuinely difficult to obtain and are not granted as a matter of course. The time limit encourages claimants to act swiftly even when full estate details are not yet known, which is precisely why early legal advice matters so much.
The procedural steps to commence a claim are:
- Obtain the will and death certificate as soon as possible after the death.
- Seek legal advice to confirm eligibility and assess the merits of your claim.
- Consider lodging a caveat if probate has not yet been granted, to prevent premature distribution of the estate.
- File a Summons and affidavit in the Supreme Court of NSW, naming the executor or administrator as respondent.
- Participate in case management, which typically includes directions hearings and referral to alternative dispute resolution.
- Attend mediation before any final hearing, as the court actively encourages resolution at this stage.
- Proceed to a final hearing if mediation does not resolve the dispute.
Pro Tip: Filing within the 12-month window preserves your legal rights and gives you time to gather evidence and attempt mediation. Missing the deadline does not automatically end your claim, but it makes everything significantly harder and more expensive.
How does the court decide a family provision claim?
The court does not ask whether the will was fair. It asks whether the deceased made adequate provision for the claimant’s proper maintenance, education, or advancement in life. This is a specific legal test, and the distinction matters. A will can be entirely valid and still fail this test.
The court applies the factors set out in section 60(2) of the Succession Act 2006 (NSW), which include:
- The nature and duration of the relationship between the claimant and the deceased
- The claimant’s current and future financial needs and resources
- The size and nature of the estate
- Any contributions the claimant made to the deceased’s welfare or property
- The conduct of the claimant, both before and after the death
- The competing claims of other beneficiaries
Evidence is the foundation of any successful claim. Useful documents include the current will and any previous wills, the deceased’s solicitor files, medical records, financial statements, bank records, and witness statements from people who can speak to the relationship. Courts respond to specificity. Vague assertions about a close relationship carry far less weight than documented evidence of financial dependency or regular caregiving.
A common pitfall is underestimating how much evidence is needed even when settlement seems likely. Alternative dispute resolution through mediation regularly resolves family provision claims before a final hearing, but a well-evidenced claim produces a far better mediation outcome than a poorly prepared one.
Contesting a will vs. challenging its validity: what is the difference?
These two processes are frequently confused, and the distinction has real consequences for legal strategy, evidence requirements, and court procedure.
| Feature | Family provision claim (contesting) | Validity challenge (challenging) |
|---|---|---|
| Legal basis | Succession Act 2006 (NSW), s 57 | Common law and equity |
| Core question | Was adequate provision made? | Is the will legally valid? |
| Grounds | Inadequate provision for eligible person | Lack of capacity, undue influence, fraud, improper execution |
| Who can bring it | Eligible persons only | Any interested party |
| Typical evidence | Financial records, relationship history | Medical records, witness testimony, solicitor notes |
| Outcome if successful | Court orders additional provision from estate | Will declared invalid; prior will or intestacy rules apply |
A validity challenge is the appropriate path when you believe the will does not reflect the deceased’s genuine intentions, for example because they lacked testamentary capacity due to dementia, or because another person exerted undue influence over them. This is a separate legal action with different grounds and different evidence. Some claimants pursue both simultaneously, which requires careful legal coordination.
What practical steps should eligible persons take right now?
Acting early is not just good advice. It is a legal necessity given the 12-month deadline. The following steps give you the best chance of protecting your rights and achieving a fair outcome.
Gather documents immediately. Obtain the will, the death certificate, any correspondence with the deceased about inheritance, and your own financial records. Courts require detailed evidence of your financial position, so start compiling this early.
Seek legal advice before doing anything else. Eligibility is a critical gateway requirement, and a lawyer can assess your standing and the merits of your claim in a single consultation. Acting on assumptions about eligibility is one of the most common and costly mistakes claimants make.
Consider lodging a caveat if probate has not been granted. A caveat prevents the court from issuing a grant of probate without notifying you, which gives you time to take action before the estate is distributed and potentially depleted.
Understand mediation as a genuine resolution pathway. The Supreme Court of NSW actively facilitates mediation in family provision matters, and most claims settle at this stage. A negotiated outcome is typically faster, cheaper, and less emotionally taxing than a contested hearing.
Pro Tip: Do not wait until you have all the information before contacting a lawyer. The 12-month clock does not pause while you gather documents. A lawyer can file a protective claim and continue building the evidence base in parallel.

What I have learned from contested estate matters in NSW
From my experience working on family provision claims across Sydney, the single biggest mistake I see is people waiting. They wait until they have read the will carefully, until they have spoken to other family members, until they have “figured out” whether they have a case. By the time they come to us, three, four, sometimes eight months have already passed. The 12-month window sounds generous until you account for the time needed to gather evidence, instruct a lawyer, draft an affidavit, and file in the Supreme Court of NSW.
The second thing I have noticed is that people dramatically underestimate the importance of evidence at mediation. Most family provision claims in NSW do settle before a final hearing, which is genuinely good news. But the settlement you achieve at mediation is almost entirely determined by the strength of your evidence file. A claimant with detailed financial records, a clear account of their relationship with the deceased, and documented contributions to the estate will consistently achieve a better outcome than someone who arrives at mediation with a general sense of grievance and little else.
My honest view is that the emotional weight of these disputes often works against claimants. Grief, family conflict, and the sense of betrayal that comes with being left out of a will can make it hard to think clearly about strategy. The best thing you can do is separate the emotional from the legal as early as possible. Get advice, understand your position, and let the process do its work. Mediation, in particular, gives families a way to resolve these disputes without the full adversarial weight of a court hearing, and I have seen it produce genuinely fair outcomes in matters that looked intractable at the outset.
