Challenging a Will in Queensland: Grounds for Contesting and the Legal Process

General Information Only: This article is general information, not legal advice. For advice specific to your circumstances, consult a qualified Queensland estate lawyer.

Quick Answer

In Queensland, you can challenge a will’s validity on grounds such as lack of testamentary capacity, undue influence, fraud or forgery, or improper execution, and you can separately contest a will through a family provision claim if it fails to adequately provide for you. Family provision proceedings must generally be instituted within 9 months of the date of death (Succession Act 1981 (Qld) s 41(8)), and it is standard practice to give the executor written notice within 6 months so that the protection in s 44 does not let the personal representative distribute early without regard to your claim. Most disputes resolve through mediation rather than a full trial, and legal costs are often — but not always — paid from the estate.

Whether you fall into one of these categories — and therefore have standing to act — is the threshold question in any challenge. See our guide on who can contest a will for the full list of eligible parties.

Disputes about wills are more common than many people realise. In Queensland, certain family members and other eligible parties can contest or challenge a will if they believe the will is invalid, was not properly made, or fails to make adequate provision for an eligible spouse, child or dependant. This article outlines the reasons someone might contest a will, who has legal standing to do so, the grounds the court recognises, and the legal process under Queensland law.

Why Wills Can Be Contested

A will is meant to reflect the testator’s wishes regarding how their assets and estate should be distributed. Sometimes, a beneficiary or potential claimant feels the will:

Modern estates increasingly include online accounts, cryptocurrency and other online property that can be easy to overlook. Our guide to digital assets in Queensland wills explains why recording these clearly can help reduce later disputes.

• Fails to account for them properly or at all.
• May have been executed under suspicious circumstances (e.g., undue influence).
• Might be invalid due to formal or mental capacity issues.

Queensland’s legal system aims to protect both testamentary freedom and the legitimate interests of eligible dependants. So while courts strive to honour the deceased’s intentions, they also provide routes to challenge a will if genuine concerns exist.

Key Grounds for Contesting a Will in Queensland

Below is a table summarising common grounds for challenging a will, each recognised under Queensland law:

Lack of Testamentary Capacity

For a will to be valid, the testator must understand what assets they own, who might expect to inherit, and the will’s effect. If mental capacity is compromised — through illnesses like dementia or severe cognitive impairment — beneficiaries can argue the testator lacked capacity.

Undue Influence

Undue influence arises if someone exerts coercion or intimidation on the testator to direct assets in ways not of the testator’s own free volition. Unlike lifetime gifts, there is no presumption of undue influence in the will-making context — the person alleging it bears the onus of proving actual coercion that overbore the testator’s free will, which is a high bar without documentation or independent witnesses.

Fraud or Forgery

A will can be challenged if it was forged, tampered with, or if the testator was deceived about the nature of the document they were signing (for example, being told they were signing something else entirely). These claims turn on evidence such as handwriting analysis, witness accounts, and the circumstances surrounding execution.

Improper Execution

Under s 10 of the Succession Act 1981 (Qld), a will must be in writing, signed by the testator (or by someone else in the testator’s presence and at their direction), with that signature made or acknowledged in the presence of two or more witnesses present at the same time, and at least two witnesses must attest and sign in the testator’s presence. If these formalities are not met, the will may be challenged as improperly executed — though Queensland courts have a dispensing power to admit an informal will if satisfied it reflects the deceased’s genuine testamentary intentions.

Informal wills (s 18): Even where a document does not meet the formal signing and witnessing requirements, the Supreme Court may admit it under section 18 of the Succession Act 1981 (Qld) if satisfied the deceased intended it to form their will. These applications are evidence-heavy and can be costly, which cuts both ways: an improperly executed will is not automatically invalid, so a challenge based only on a technical execution defect may fail if the court is satisfied of testamentary intention.

Knowledge and Approval

A will can also be challenged on the basis that the testator did not know and approve of its contents, even where capacity and execution formalities appear satisfied. This ground is most often raised in suspicious circumstances — for example, a will made suddenly late in life, a significant departure from earlier wills, a beneficiary who was involved in preparing the will, or concerns about the testator’s literacy, language or cognitive decline at the time.

Family Provision Claims (Inadequate Provision)

Under s 41 of the Succession Act 1981 (Qld), close relatives — spouse (including de facto), children, and certain dependants — can claim the will (or an intestacy) fails to provide them with adequate support. The court considers whether adequate provision has been made for the applicant’s proper maintenance and support, weighing matters such as the size of the estate, the applicant’s needs and resources, any competing claims, the relationship history, and any provision already made.

Who Can Contest a Will in Queensland?

Standing to challenge a will depends on which type of claim you’re making:

• Family provision claims: Under s 40 and s 41 of the Succession Act 1981 (Qld), an eligible applicant is the deceased’s spouse (including a de facto partner), a child (including a stepchild under s 40A, provided the step-relationship had not ended before death, or an adopted child), or a dependant — meaning a person who was wholly or substantially maintained or supported by the deceased at the time of death, and who is either a parent of the deceased, the parent of the deceased’s surviving child under 18, or a person under 18. The maintenance requirement applies to all three categories: a parent of the deceased is only an eligible dependant if they were actually being financially maintained by the deceased — being a parent alone is not enough.
• Validity challenges (capacity, undue influence, fraud, improper execution): standing is broader and generally extends to anyone with a genuine financial interest in the outcome — for example, a beneficiary under an earlier will, or a next of kin who would benefit if the will were set aside and the estate passed under intestacy rules.

Being eligible to apply does not guarantee success — the court still weighs the merits, the size of the estate, and competing claims from other beneficiaries.

Time Limit to Contest a Will in Queensland

Time limits differ depending on the type of challenge:

• Family provision claims: proceedings must generally be instituted within 9 months of the date of death (s 41(8)) — not from the date probate is granted. The court can extend this time, but only on application, and an applicant relies on the court’s leave rather than a right.
• Notice to the executor: giving written notice of an intended claim within 6 months of death protects your position, because s 44 otherwise allows the personal representative to make a proper distribution not earlier than 6 months after death if it has not received written notice of a family provision application or intended application. If written notice has been received, that protection may instead apply to a proper distribution made not earlier than 9 months after death, unless the representative receives written notice that proceedings have been commenced or is served with the application.
• Validity challenges: there is no fixed statutory limitation period, but practically a challenge is far easier to bring before a grant of probate issues (see caveats, below) — after a grant, the challenger must apply to revoke it, a more complex proceeding.

Where a family provision claim is filed late, the court considers factors including the sufficiency of the explanation for the delay, the strength of the claim, prejudice to the beneficiaries, whether the estate has already been distributed, and any unconscionable conduct — a late applicant must also show a substantial case on the merits (see, e.g., Mortimer v Lusink [2017] QCA 1). A solicitor should confirm how these factors apply to your circumstances before relying on a late application.

Validity Challenge vs. Family Provision Claim: Key Differences

People often use “challenging” and “contesting” a will interchangeably, but they describe two legally distinct pathways:

Legal Process for Challenging a Will

Step 1: Seek Preliminary Advice

If you suspect grounds exist to contest a will — lack of capacity, undue influence, or inadequate provision — contact a solicitor experienced in Queensland wills and estate disputes. They can help gather medical records, witness statements, or financial evidence.

Step 2: File a Caveat (If Needed)

A caveat is a formal notice to the Supreme Court of Queensland preventing a grant of probate (or letters of administration) from being made without notifying the caveator. This can pause the estate’s administration temporarily, giving the challenger time to prepare their case. A caveat is not permanent — it generally lapses after around 6 months unless renewed, and if the caveator does not then take steps to have the will proved in solemn form, the executor can move to have it removed. (The court can set aside a caveat under UCPR r 626 if the evidence does not raise a genuine doubt about the grant; a caveat used tactically may attract costs consequences.) If no caveat is lodged and probate is granted, contesting the will’s validity becomes more difficult — the challenger must instead apply to revoke the grant, a more complex proceeding — though not impossible. Important: a caveat is a tool for validity/grant concerns only; a family provision claim is made against the estate itself and does not require a caveat. Lodging one without a proper basis can expose you to a costs or compensation claim.

Step 3: Lodge Court Documents

The exact process varies depending on the ground:

• Inadequate Provision Claim: The applicant files an application under Part 4 (s 41) of the Succession Act 1981, detailing why they deserve greater provision. Proceedings generally must be instituted within 9 months of the date of death (s 41(8)), and it is standard practice to give the executor written notice within 6 months — because s 44 may protect a personal representative who makes a proper distribution not earlier than 6 months after death without notice of a claim (or not earlier than 9 months where notice was given, unless proceedings have been commenced or served).
• Validity Challenges: The claimant applies to the court to revoke or refuse probate, citing undue influence, capacity issues, fraud, or improper execution.

Step 4: Court Considerations & Mediation

Mediation is generally a required step before a family provision claim proceeds to trial, under Supreme Court of Queensland Practice Direction 14 of 2023 (Wills and estates list), which builds mediation into the standard directions for family provision applications, and most claims settle at this stage rather than running to judgment. If mediation does not resolve the dispute, the matter proceeds to a trial, where a judge examines:

• Evidence of the deceased’s condition or influences at the will’s signing.
• The claimant’s financial position and the estate’s total value (for family provision).
• Whether formalities under s 10 were satisfied (two witnesses, the testator’s signature, etc.).

Step 5: Court Ruling & Possible Outcomes

The Supreme Court might:

• Uphold the existing will.
• Modify it, granting the claimant additional provision.
• Declare the will (or certain clauses) invalid, potentially reverting to a prior will or intestacy.
• Issue cost orders, often drawn from the estate, though the claimant might bear their own costs if the case is weak or frivolous.

Checklist: First Steps If You’re Considering a Challenge

• Get the will and any earlier wills. Under s 33Z of the Succession Act 1981 (Qld), an “entitled person” (including a spouse, child, anyone named in the current or an earlier will, and anyone who may bring a family provision claim) has a statutory right to inspect the will or obtain a certified copy — the holder cannot refuse, though you pay the reasonable cost of the copy. See Notifying Beneficiaries: What an Executor Must Tell Them and When.
• Note the date of death. Both the 6-month notice guideline and the 9-month filing deadline for family provision claims run from this date, not from when probate is granted.
• Gather supporting evidence early. Medical records, correspondence, and witness accounts are hardest to obtain the longer you wait.
• Check whether probate has been applied for. If not, and you have validity concerns, a caveat may be appropriate.
• Get advice on standing and merits before committing. Not every grievance amounts to a legal ground, and costs risk applies to weak claims.
• Consider mediation early. Most Queensland will disputes settle without a trial.

Practical Example: Family Provision Claim

Suppose a widowed father left most of his estate to a charity, giving minimal sums to two adult children. One child — recently unemployed and with health issues — believes the father owed them support. That child might file a family provision claim, demonstrating financial need and minimal inheritance. The court weighs:

• The father’s reasons for excluding or limiting that child’s share.
• The child’s current resources and dependants.
• The overall estate size.

If the court deems it fair, it can alter the distribution so the child receives a greater portion.

Costs of Contesting a Will

Costs depend heavily on the type of claim and how far it progresses:

• Family provision claims: If reasonably arguable, a successful applicant’s costs are often paid from the estate. An unsuccessful or unreasonably pursued claim can leave the applicant paying their own costs, and in some cases the other side’s.
• Validity challenges: Courts sometimes allow the costs of a genuine, reasonably based challenge to be paid from the estate on the basis that the deceased’s true intentions needed testing — but a challenge brought without a proper basis carries real personal costs risk for the person bringing it.
• Mediation: Typically far cheaper than a Supreme Court trial, and the majority of Queensland will disputes resolve at this stage.

Even when costs are ultimately paid from the estate, this reduces the pool available for all beneficiaries — a real consideration when weighing whether to bring or defend a claim. Because costs outcomes are discretionary and fact-specific, get a costs estimate and an honest view on merits from a solicitor before commencing a claim.

Not every dispute is a validity challenge or a family provision claim. Some disputes involve neither invalidity nor inadequate provision: they turn on construing ambiguous wording in the will, rectifying a drafting error so the will reflects what the testator actually intended, or determining whether a gift has failed. These are separate court processes that need tailored advice, and forcing such a problem into the wrong pathway can waste time and costs.

No-Contest (In Terrorem) Clauses

Some wills include a clause stating that a beneficiary who challenges the will forfeits their gift. In Queensland, these clauses do not prevent a person from bringing a genuine family provision claim, and their enforceability more broadly is limited. See No-Contest Clauses in Queensland Wills: Are They Enforceable? for a full discussion.

Frequently Asked Questions

1. How long do I have to contest a will in Queensland?
For a family provision claim, you generally have 9 months from the date of death to institute proceedings (s 41(8)). However, contacting a solicitor sooner is advisable, since a written notice within 6 months protects your position against early distribution (s 44).

2. Is it costly to challenge a will?
Disputes can be expensive and time-consuming, especially if they proceed to trial. Some matters settle via mediation. Costs often come from the estate, but claimants might incur their own fees if the court finds their claim unfounded.

3. Does having a strong moral claim guarantee success in a family provision application?
Not necessarily. Courts also evaluate the estate’s size, other beneficiaries, and the testator’s reasons for their distribution. Each case is distinct.

4. Can siblings use undue influence claims if they simply disagree with the will’s contents?
No. Disliking a will is insufficient. Proving undue influence requires showing someone actively overrode the testator’s free will, usually with strong, clear evidence.

5. What if the will is missing or suspected to be lost or forged?
You might seek an order from the court to prove a lost will, or challenge authenticity if you have evidence of forgery. Courts rely on statutory rules and witness testimony to determine if the will is valid.

6. What is the difference between contesting and challenging a will in Queensland?
Challenging a will disputes its validity (for example, capacity, undue influence, or forgery), which can render the whole will void. Contesting a will — through a family provision claim — accepts the will is valid but asks the court for a larger share because adequate provision was not made.

7. Who is eligible to contest a will in Queensland?
Under ss 40–41 of the Succession Act 1981 (Qld), a deceased person’s spouse or de facto partner, children (including adopted and stepchildren), and certain dependants may apply for family provision. A dependant must have been wholly or substantially maintained by the deceased — for example, a parent of the deceased is only eligible if they were financially dependent on their child, not simply by virtue of being a parent. Eligibility does not guarantee an award — the court weighs need, the size of the estate, and the applicant’s relationship with the deceased.

8. How long does it take to resolve a will dispute in Queensland?
Straightforward matters settled at mediation can conclude within a few months, while contested claims that proceed to a Supreme Court hearing may take 12 to 24 months. Acting quickly to obtain advice and meet the 9-month family provision deadline is the single biggest factor in avoiding delay.

9. Does contesting a will stop probate being granted?
Only if you lodge a caveat. Without one, probate can be granted while you prepare a family provision claim (the claim itself isn’t affected, since it’s made against the estate rather than against the grant), but validity challenges are far harder to run once assets have already been distributed.

10. Can a no-contest clause stop me from making a claim?
No. A clause purporting to disinherit a beneficiary for bringing a family provision claim does not override your statutory right to apply under the Succession Act 1981 (Qld).

11. Can a caveat permanently stop probate?
No. A caveat only pauses matters temporarily — it generally lapses after around 6 months unless renewed, and if the caveator does not take steps to have the will proved in solemn form, the executor can move to have it removed and probate granted.

12. Do I have a right to see the will?
Yes. Under s 33Z of the Succession Act 1981 (Qld), an “entitled person” — including anyone named in the current or an earlier will, a spouse, child, or someone who may bring a family provision claim — can require the person holding the will to allow inspection or provide a certified copy, on payment of the reasonable cost of the copy.

Conclusion

By recognising the acceptable grounds and legal steps for contesting or challenging a will, individuals can better evaluate the merits of their claim. If you suspect an unjust or invalid will, seeking prompt legal advice ensures you meet deadlines and comply with Queensland’s procedural rules.

Key Takeaways & Summary

Challenging a will in Queensland involves specific grounds — like lack of capacity, undue influence, fraud, or inadequate provision under the Succession Act. The legal process often includes lodging caveats, applying to court, and possible mediation, culminating in a judicial decision if disputes aren’t resolved earlier.

• Grounds: Valid reasons include mental incapacity at execution, undue influence, fraud/forgery, improper execution, or insufficient provision to eligible family (s 41).
• Standing: Family provision claims are limited to a spouse, child, or dependant who was actually maintained by the deceased (ss 40–41) — a parent is not automatically eligible; validity challenges have broader standing.
• Time Limits: Family provision proceedings generally must be instituted within 9 months of death (s 41(8)); notify the executor within 6 months to protect your position (s 44).
• Court’s Role: The Supreme Court of Queensland weighs evidence, testamentary freedom, and fairness to claimants.
• Costs & Complexity: Contests can be lengthy; some settle via mediation. Seek a solicitor’s advice to understand viability and manage potential costs risk.
