Who Can Contest a Will in NSW? Eligibility and Time Limits Explained

Feeling left out of a will doesn't automatically mean you can contest it. Here's who the law recognises as an eligible person in NSW, what courts actually weigh up, and the time limit that matters most.

Discovering you’ve been left out of a will, or received far less than expected, is difficult on its own. Understanding whether you can actually do anything about it is a separate question — and the answer depends on specific legal criteria, not just how unfair the outcome feels.

What “Contesting a Will” Actually Means

In NSW, most challenges to a Will take the form of a family provision claim, an application to the Supreme Court asking for a share, or a larger share, of a deceased person’s estate. This is different to disputing that a Will is valid in the first place (for example, on the basis of undue influence or lack of capacity), which is a separate kind of claim.

Who Is an “Eligible Person”

Under the Succession Act 2006 (NSW), only certain people can bring a family provision claim: a spouse of the deceased, a person who was in a de facto or close personal relationship with the deceased, a child of the deceased (including adult children), a former spouse, and, in more limited circumstances, a grandchild or a person who was a member of the deceased’s household, in either case where they were wholly or partly dependent on the deceased. Being disappointed by a Will, on its own, isn’t enough; you need to fit within one of these categories.

What the Court Actually Considers

Even an eligible person doesn’t automatically succeed. The Court looks at the nature and duration of the applicant’s relationship with the deceased, the applicant’s financial resources and needs (present and future), the size and nature of the estate, any financial or other contributions the applicant made, whether the applicant was being maintained by the deceased, and the applicant’s character and conduct. The outcome depends on all of these factors together, not on any single one.

The Time Limit That Catches People Out

A family provision claim is subject to a strict 12-month time limit from the date of death. The Court can extend this only in limited circumstances, and that’s not something to rely on. If you’re considering a claim, or you’re an executor concerned one might be made, getting advice early matters far more than it might seem to at first.

If You’re an Executor Facing a Claim

Executors aren’t expected to fight every claim on principle, sometimes a negotiated outcome protects the estate better than prolonged litigation. Executors do need to be cautious about distributing the estate too early, since distributing before the 12-month window (or a known claim) has passed can create personal risk.

FAQ
Who Can Contest a Will in NSW? Eligibility and Time Limits Explained
Can anyone contest a Will in NSW? +

No. Only people who fall within the categories of "eligible person" under the Succession Act 2006 (NSW) — broadly, a spouse, de facto or close personal partner, child, former spouse, or certain dependent grandchildren or household members can bring a family provision claim.

What's the time limit to contest a Will? +

A strict 12 months from the date of death. The Court can extend this only in limited circumstances, and it shouldn't be relied on.

Does being an adult child guarantee I can make a successful claim? +

Adult children are generally eligible to apply, but eligibility isn't the same as success — the Court weighs a range of factors, including your relationship with the deceased and your financial position.

What's the difference between contesting a Will's validity and making a family provision claim? +

Disputing validity challenges whether the will itself is legally sound (for example, due to lack of capacity or undue influence). A family provision claim accepts the Will is valid but asks the Court for a share, or larger share, of the estate.

I'm an executor and someone has told me they intend to contest the Will — what should I do? +

Get legal advice early, and be cautious about distributing the estate until the position is clearer, given the personal liability risk if you distribute too soon.
