Locus standi in probate is the legal concept that defines who has the right to bring a claim, lodge a caveat, or participate in proceedings concerning a deceased estate in Australian courts. The Latin phrase translates literally to “place of standing,” and in the probate context it means you must hold a recognised legal interest in the estate before a court will hear you. Without it, your claim will not get off the ground. Understanding what is locus standi probate, and whether you satisfy the threshold, is the first question any solicitor will ask before advising you to take action. Simons George Legal works with clients across Sydney to assess standing early, saving time and cost before a single document is filed.
What is locus standi in probate, and why does it matter?
Locus standi is defined as the legal capacity to bring or defend proceedings in a court. In probate law, this capacity depends on whether you hold a genuine interest that would be affected by the grant of probate or the administration of the estate. A general sense of unfairness about a will is not enough. Courts require a concrete legal stake.
The concept matters because probate proceedings carry real consequences for estate assets, beneficiaries, and creditors. Australian courts apply locus standi requirements under legislation including the Succession Act 2006 (NSW) and the Administration and Probate Act 1958 (Vic). These statutes set out who qualifies as an eligible person and what interests attract standing. Getting this wrong at the outset can result in a dismissed claim and an adverse costs order against you.

Locus standi also shapes the procedural steps available to you. A person with standing can lodge a probate caveat, commence proceedings to challenge will validity, or file a family provision claim. Each pathway has its own standing test, and they are not interchangeable.
Who has locus standi in probate cases?
The categories of people recognised as having probate standing requirements differ depending on the type of claim. The two main pathways are will validity challenges and family provision claims, and each draws its eligible persons from a different pool.
For will validity challenges, standing is relatively broad. The following people typically qualify:
- Beneficiaries named in an earlier will who would receive more if the later will were set aside
- People entitled to inherit on intestacy if no valid will exists
- Executors named in a competing will
- Creditors of the estate with a direct financial interest
- Anyone whose legal rights are directly affected by the grant of probate
For family provision claims, the pool is narrower. Legislation in each state defines “eligible persons” by reference to their relationship with the deceased. In NSW under the Succession Act 2006, eligible persons include spouses, de facto partners, children, former spouses in certain circumstances, and people who were wholly or partly dependent on the deceased. Standing requires showing a genuine legal interest affected by the grant of probate, not merely disappointment with the outcome.
The distinction matters practically. A niece who receives nothing under a will may have standing to challenge its validity if she was a beneficiary under an earlier will. She may not, however, have standing to bring a family provision claim if she does not fall within the statutory definition of an eligible person under the relevant state legislation.

Pro Tip: Before lodging any claim or caveat, confirm which category of standing applies to your situation. Mixing up the two pathways is one of the most common and costly mistakes in contested estate matters.
How does locus standi differ between will validity challenges and family provision claims?
Distinguishing these two claim types is vital for a claim’s success. They serve different purposes, attract different standing tests, and produce different outcomes if successful.
A will validity challenge attacks the legal integrity of the will itself. Common grounds include lack of testamentary capacity, undue influence, fraud, or failure to comply with execution requirements. You can read more about the grounds for contesting a will in detail. If the challenge succeeds, the will is declared invalid and the estate passes under an earlier valid will or on intestacy.
A family provision claim does not attack the will’s validity. It accepts the will as legally sound but argues that the deceased failed to make adequate provision for the claimant’s maintenance, education, or advancement in life. If successful, the court orders a redistribution of estate assets in the claimant’s favour.
The procedural steps for each differ in the following ways:
- Identify your standing category. Determine whether you are challenging validity or seeking provision. The answer dictates which legislation applies and which court you file in.
- Gather the right evidence. Validity challenges require medical records, witness statements, and testamentary documents. Family provision claims require financial evidence showing your needs and the deceased’s obligations toward you.
- File within the correct time limit. Each claim type carries its own limitation period, which varies by state.
- Serve the correct parties. Validity challenges typically require service on the executor and all beneficiaries. Family provision claims require service on the legal personal representative.
Misclassifying claims often leads to dismissal, which wastes time and money. Getting the classification right from the start is not optional.
Pro Tip: If you are unsure which type of claim applies to your circumstances, seek legal advice before filing anything. An incorrectly filed claim can prejudice your position in subsequent proceedings.
What are the time limits for locus standi claims across Australian states?
Time limits are among the most unforgiving aspects of probate standing. Missing a deadline can extinguish a valid claim entirely, regardless of how strong the underlying case is.
Family provision claims must be commenced within the statutory time even if the claimant was unaware of the will’s contents earlier. Late knowledge of estate details does not automatically extend the deadline.
| State | Family provision claim limit | Will validity challenge |
|---|---|---|
| NSW | 12 months from date of death | No fixed statutory limit; delay may prejudice claim |
| Victoria | 6 months from grant of probate | No fixed statutory limit; promptness expected |
| Queensland | 9 months from date of death | No fixed statutory limit |
| South Australia | 6 months from grant of probate | No fixed statutory limit |
| Western Australia | 6 months from grant of probate | No fixed statutory limit |
Limitation periods differ by state: NSW requires family provision claims within 12 months of death, while Victoria allows 6 months from the grant of probate. That difference of several months can be decisive if you are slow to act after a loved one’s death.
Courts can grant extensions in limited circumstances, but the bar is high. You must demonstrate a compelling reason for the delay and show that granting an extension would not cause undue prejudice to the estate or other beneficiaries. Courts do not treat ignorance of the law as a sufficient reason. Acting promptly after a death, and seeking legal advice within weeks rather than months, is the only reliable way to protect your position.
What evidence and procedural steps establish locus standi in probate disputes?
Courts do not accept bare assertions of standing. You must demonstrate your interest with concrete evidence before proceedings can advance.
The key evidential and procedural considerations include:
- Proof of your legal interest. This means producing the relevant will naming you as a beneficiary, evidence of your relationship to the deceased, or documentation showing your entitlement on intestacy.
- Prior testamentary documents. If you rely on an earlier will to establish standing, you must produce that document and show it was valid at the time of execution.
- Financial evidence for family provision claims. Courts assess your current financial position, your future needs, and the size of the estate. Bank statements, tax returns, and medical reports are commonly required.
- Caveat procedure. A probate caveat prevents the grant of probate from issuing while a dispute is examined. It is a protective step, not a determination of validity. Once lodged, the executor can issue a warning, requiring you to file an appearance and state your interest. Failure to file an appearance results in removal of the caveat.
- Character and conduct. Courts consider the claimant’s conduct when deciding family provision applications. Dishonesty, violence, or abandonment can disentitle an applicant regardless of their statutory standing.
Filing a caveat without a genuine legal interest risks immediate removal and adverse cost orders against the caveator. Courts treat improper caveats as vexatious filings and respond accordingly. The evidential threshold is real, and courts enforce it.
Pro Tip: Gather all relevant documents, including prior wills, correspondence with the deceased, and financial records, before lodging a caveat or commencing proceedings. Courts expect you to have a substantive basis ready, not a placeholder.
How does understanding locus standi assist you in an inheritance dispute?
Knowing your standing position before you act is the single most useful thing you can do in a contested estate matter. It shapes every decision that follows.
Understanding probate case standing allows you to assess your rights early and avoid filing claims that courts will dismiss. A dismissed claim wastes legal costs and can prejudice your credibility in any subsequent proceedings. It also gives you a clear basis for communicating with the executor and other beneficiaries, which can open the door to negotiated settlements without court involvement.
For executors, understanding who has locus standi helps you respond appropriately to caveats and claims. Not every person who contacts you with a grievance has legal standing. Knowing the threshold means you can seek removal of improper caveats efficiently and protect the estate from unnecessary delay. You can review the estate administration steps to understand your obligations as executor alongside any disputes.
Strategic decision-making in inheritance disputes depends on an accurate assessment of standing. If you have standing, you can negotiate from a position of strength. If your standing is uncertain, you can take steps to strengthen it before committing to litigation. Either way, clarity about locus standi is the foundation of a sound legal strategy.

What I have learned about locus standi after years in probate disputes
The question I hear most often from clients is: “Can I contest this will?” My answer is always the same. Before we talk about whether you should, we need to establish whether you legally can.
The most common mistake I see is people lodging caveats or threatening proceedings without any clear basis for standing. They are upset, which is understandable. Grief and a sense of injustice are powerful motivators. But courts are not moved by emotion. They require a legal interest, and if you cannot articulate one, your filing will be removed and you will likely face a costs order on top of your grief.
The second mistake is conflating a validity challenge with a family provision claim. These are fundamentally different proceedings with different standing tests, different evidence requirements, and different outcomes. I have seen clients spend months pursuing the wrong type of claim before realising their error. By that point, time limits on the correct claim may have expired.
My advice is this: seek legal advice within weeks of a death if you think there is a dispute. Do not wait until you have read the will, spoken to the executor, or decided you are definitely going to act. The earlier you get advice, the more options you have. Locus standi is not a technicality to be dealt with later. It is the first question, and the answer determines everything else.

FAQ
What does locus standi mean in probate?
Locus standi in probate means having the legal right to bring a claim or participate in proceedings concerning a deceased estate. A court will not hear your matter unless you hold a recognised interest in the estate, such as beneficiary status or entitlement on intestacy.
Who has locus standi to contest a will in Australia?
Beneficiaries under a prior will, people entitled on intestacy, and competing executors typically have standing to challenge will validity. Family provision claims are limited to eligible persons defined by statute, such as spouses, children, and dependants of the deceased.
What happens if you lodge a caveat without proper standing?
A caveat filed without a genuine legal interest will be removed by the court. The caveator also risks an adverse costs order, meaning they may be required to pay the legal costs of other parties caused by the improper filing.
Are time limits the same in every Australian state?
No. In NSW, family provision claims must be filed within 12 months of the date of death. In Victoria, the limit is 6 months from the grant of probate. Other states apply their own periods, and courts rarely grant extensions without compelling justification.
Can character or conduct affect locus standi?
Statutory standing and character are separate issues, but conduct can affect the outcome of a family provision claim. Courts may refuse an application where the claimant’s past behaviour, such as violence or abandonment of the deceased, disentitles them despite their technical eligibility.
