Challenging a Will in Queensland — Grounds, Evidence & Procedure

Grounds for challenging a will in Queensland

Under Queensland law, a will may be challenged on one or more of the following grounds. Each ground has distinct legal elements that must be proved. Challenges are often brought on multiple grounds in the alternative — for example, alleging both lack of capacity and undue influence. The Succession Act 1981 (QLD) governs these challenges, supplemented by the common law as developed through the Supreme Court of Queensland and the Uniform Civil Procedure Rules 1999 (QLD) Chapter 15.

Lack of Testamentary Capacity

The testator did not have the mental capacity required to make a valid will at the time of execution. Queensland Courts apply the Banks v Goodfellow (1870) test: the testator must understand the nature of making a will, the extent of their property, the claims of those who might expect to benefit, and be free from any disorder of the mind that would poison their affections. Medical evidence — particularly contemporaneous records — is central to capacity challenges in QLD.

Undue Influence

The testator's free will was overborne by coercion such that the will does not represent their true intentions. Undue influence is not mere persuasion, advice, or family pressure. It requires proof that the testator was not a free agent. In Queensland, the person alleging undue influence bears the onus of proof and must produce evidence that is clear, cogent, and precise — the Briginshaw standard applies commensurate with the seriousness of the allegation.

Fraud or Forgery

The will is not genuine — it was forged, altered after execution, or procured by fraudulent misrepresentation. This is the most serious allegation in probate law. In Queensland, will forgery also carries criminal consequences: under s 488 of the Criminal Code 1899 (QLD), a person who forges a will with intent to defraud is liable to imprisonment for 14 years. Evidence may include forensic document examination, handwriting analysis, and testimony from witnesses and the drafting solicitor.

Suspicious Circumstances

Where circumstances surrounding the will's preparation and execution arouse the Court's suspicion, the evidential burden shifts to the propounder to prove the testator knew and approved the will's contents. Suspicious circumstances in QLD may include: the will being prepared by a major beneficiary, the testator being isolated from independent advice, radical departures from longstanding intentions, or execution in unusual circumstances including signature position issues under s 10(2) of the Succession Act 1981.

Want of Knowledge and Approval

The testator did not know or approve the contents of the will they signed. This is distinct from capacity — a person may have capacity but not understand what a particular document says because it was not read to them or explained properly. Where suspicious circumstances exist, the propounder must affirmatively prove knowledge and approval. In QLD, this ground often arises alongside questions about the testator's understanding of the document they signed.

Defective Execution & the s 18 Dispensing Power

Under s 18 of the Succession Act 1981 (QLD), the Court may admit to probate a document that does not comply with formal execution requirements if satisfied the deceased intended it to form their will. This is particularly relevant in QLD because of the strict s 10(2) positional signature rule requiring the signature to be at the foot or end of the will. A party opposing an informally executed document must scrutinise the evidence of intention carefully.

Checklist: Does your situation support a QLD will challenge?

The will was made when the deceased was very elderly, unwell, or heavily medicated
The deceased had a dementia diagnosis or cognitive impairment at the relevant time
The will was changed suddenly after years of consistent estate planning
A person who previously received little now receives the bulk of the estate
The main beneficiary arranged the solicitor or was present when instructions were given
The deceased was isolated from family and long-standing advisors
The signature appears irregular, in an unusual position, or unlike the deceased's known signature
Earlier wills have disappeared or cannot be located (consider the s 24(2) lost will presumption)
The will was made in hospital, a nursing home, or shortly before death
The witnesses to the will are the beneficiaries or their close associates
The will does not comply with s 10(2) QLD signature position requirements
There is evidence an attorney under an EPOA pressured the deceased about the will

If you have ticked several boxes

You should seek legal advice promptly. Multiple red flags warrant thorough investigation. Evidence — particularly medical records, solicitor files, and the original will itself — should be secured now. In QLD, a Notice of Intention to Oppose may need to be filed with the Supreme Court registry. Request urgent QLD advice →

Time limits and QLD procedure

There is no fixed limitation period for challenging a will on grounds of validity in Queensland. However, this does not mean you can delay:

Probate may be granted — once probate is granted by the Supreme Court of Queensland, the executor can distribute the estate. Recovering distributed assets is difficult and may require tracing proceedings.
File a Notice of Intention to Oppose — this is the QLD equivalent of a caveat. It must be filed with the Supreme Court registry and set out your grounds of opposition. Once filed, the Court will not proceed with a grant without notice to you.
Evidence degrades — witnesses' memories fade, records become harder to obtain, and documents may be lost. Early investigation is critical.
Delay weakens your position — the Court may refuse relief if you have delayed unreasonably and third-party rights have intervened. The doctrine of laches applies.
Family provision claims have their own limits — if your claim is for further provision from the estate (rather than challenging validity), different time limits apply under Part 4 of the Succession Act 1981 (QLD).

QLD Supreme Court probate procedure

The Supreme Court of Queensland exercises probate jurisdiction throughout the state. The procedure for challenging a will in QLD typically follows these stages:

Examine the Will

Review the will for formal validity, including s 10(2) signature position compliance and s 18 dispensing power considerations.

File Notice of Intention to Oppose

Lodge the Notice with the Supreme Court registry setting out your grounds of opposition before probate is granted.

Gather & Secure Evidence

Obtain medical records, solicitor files, witness statements, and forensic evidence to support each ground.

Commence Proceedings

File an Originating Application in the Supreme Court of Queensland under UCPR Chapter 15 seeking the relief appropriate to your grounds.

Trial or Mediation

Many QLD probate disputes resolve through mediation ordered by the Court. Contested matters proceed to a solemn form trial before a judge.

Note: In QLD, grants of probate in common form (uncontested) may be made by a registrar. Contested grants require a judge in solemn form. A Notice of Intention to Oppose converts a common form application into a contested matter that will be listed before a judge. The s 10(2) positional signature rule is unique to QLD and can invalidate an otherwise regular will — always check the signature position.

What to do first if you suspect grounds exist

Do not alert the suspected wrongdoer. If you suspect fraud, undue influence, or forgery, avoid confronting the person who may have procured the will. They may destroy evidence.
Secure a copy of the will. Obtain the will from the executor, the solicitor who holds it, or the Supreme Court registry if probate has been applied for. In QLD, you may be entitled to inspect the Court file once proceedings are commenced.
Secure medical and solicitor records. These are often the most critical evidence. Request them promptly — ideally before the solicitor file is destroyed under document retention policies.
Obtain legal advice immediately. QLD probate law has unique features — including the s 10(2) positional signature rule, s 18 dispensing power, s 24 lost will presumption, and the Criminal Code s 488 forgery offence — that require specialist knowledge.
Consider filing a Notice of Intention to Oppose. If probate has not been granted, this prevents the Court from sealing a grant without notice to you. This must be done with legal advice — an improperly filed Notice may result in adverse costs orders.
Document everything. Prepare a detailed chronology of events, gather correspondence, and identify potential witnesses while memories are fresh.

Common mistakes in QLD will challenges

Assuming unfairness = grounds for challenge

Many people believe a will can be challenged simply because it is unfair or because they were left out. This is incorrect. A will's validity can only be challenged on recognised legal grounds such as lack of capacity, undue influence, fraud, or want of knowledge and approval. If you have been left out of a valid will, your remedy may be a family provision claim under Part 4 of the Succession Act 1981 — a different type of claim with strict time limits.

Delaying action after death

Delay is the enemy of a successful will challenge. Once probate is granted and the estate is distributed, recovering assets becomes vastly more difficult. Evidence deteriorates with time. In QLD, you should file a Notice of Intention to Oppose as soon as concerns arise. Waiting to see what happens almost always disadvantages your position.

Ignoring QLD-specific provisions

Queensland succession law has unique features that do not exist in other states. The s 10(2) positional signature rule can invalidate a will where the signature is not at the foot or end of the document. The s 24(2) lost will presumption operates differently in QLD. Practitioners from other jurisdictions may miss these nuances. Always ensure your adviser is familiar with QLD-specific succession law.

Filing a Notice without proper grounds

A Notice of Intention to Oppose is a serious procedural step. Filing one without proper grounds, or as a tactical device to pressure the executor, can result in the Court ordering you to pay the other parties' costs on an indemnity basis. Only file a Notice on legal advice and with a genuine basis for opposition.

Assess your QLD will challenge

Challenging a will in Queensland requires understanding of the Succession Act 1981, the common law principles applied by the Supreme Court, and the unique QLD provisions — including s 10(2) signature position, s 18 dispensing power, s 24 lost will presumption, and s 488 Criminal Code forgery consequences. We can assess your grounds, identify the evidence needed, and give you a candid assessment of prospects before you commit to litigation.

Frequently asked questions — QLD will challenges

No. Queensland succession law does not recognise unfairness as a ground for challenging a will's validity. A will may be challenged only on specific legal grounds: lack of testamentary capacity, undue influence, fraud or forgery, suspicious circumstances, or want of knowledge and approval. If you believe you have been unfairly left out of a valid will, you may have a family provision claim under Part 4 of the Succession Act 1981 (QLD). This is a different type of claim and carries its own time limits — you should seek legal advice promptly as delay can prejudice such claims.

A Notice of Intention to Oppose is the QLD equivalent of a caveat in other jurisdictions. It is a document filed with the Supreme Court of Queensland registry that notifies the Court you intend to oppose a grant of probate or letters of administration. Once filed, the Court will not seal a grant without giving you notice and an opportunity to be heard. You should file a Notice of Intention to Oppose as soon as you form a genuine concern about the validity of a will — before probate is granted. The Notice must set out the grounds on which you oppose the grant. Filing a Notice is a serious step that should only be taken with legal advice. An improperly filed or tactical Notice may result in adverse costs orders against you. If the matter is resolved, you can withdraw the Notice by consent or with leave of the Court.

Section 10(2) of the Succession Act 1981 (QLD) requires that the testator's signature — or the signature of the person signing at the testator's direction — must be placed at the foot or end of the will. This is stricter than in other Australian jurisdictions. If the signature appears in the margin, on a separate page, or higher up the document, the will may be invalid on its face. This can be a powerful ground for challenge, but it is also a defect that may be cured by the s 18 dispensing power if the propounder can satisfy the Court the document expresses the deceased's testamentary intentions. When examining a QLD will for potential challenge, the signature position should always be checked. Conversely, if you are propounding a will with a signature position issue, you should prepare a s 18 application as part of your probate strategy.

Under s 488 of the Criminal Code 1899 (QLD), a person who forges a will, codicil, or other testamentary instrument — or utters or offers a document known to be forged — with intent to defraud is guilty of a crime and liable to imprisonment for 14 years. This is one of the most serious penalties for will-related fraud in Australia. The existence of criminal consequences means that allegations of forgery in QLD must be approached with particular care. If you suspect forgery, your legal team will need to consider whether to refer the matter to the Queensland Police Service. A criminal investigation may run in parallel with civil probate proceedings. Evidence gathered in one forum may be relevant in the other. The criminal dimension also heightens the evidentiary standard expected in civil proceedings — the Court will require clear, cogent, and precise evidence before making findings consistent with criminal conduct.
