Comprehensive guide on how to contest a will in England and Wales, covering legal grounds such as lack of capacity or undue influence, Inheritance Act claims, procedural steps like caveats and warnings, time limits including the six‑month deadline for financial provision claims, and practical considerations for challenging a will.

Contesting a will involves challenging the document that distributes a deceased person's estate. In England and Wales, this process is governed by specific legal principles and statutory rules. People may contest a will because they believe it is invalid, that it unfairly excludes them, or that the testator lacked capacity when making it. Successfully challenging a will can lead to it being altered, set aside or a court‑ordered award of financial provision. This article explains when and how a will can be contested, the legal grounds involved, procedural steps, time limits and practical considerations for anyone considering a challenge.
When Can You Contest a Will?
A will is a person's legally binding instructions for distributing their assets after death. It can generally be contested after the testator's death and often after probate has been granted, although acting early is crucial. The dispute may arise for different reasons, and the type of challenge influences the legal process and deadlines.
Before Probate
Where there are serious concerns about a will's validity, a person can enter a caveat at the Probate Registry. A caveat is a formal notice that stops the grant of probate for up to six months, giving time to investigate and prepare a challenge. Caveats can often be extended if necessary.
After Probate
It is possible to contest a will after probate has been granted, but the executor may have already begun distributing assets, which can complicate recovery. Acting promptly reduces this risk and helps preserve evidence and estate value.
Legal Grounds for Contesting a Will
Will contests in England and Wales generally fall into two main categories: validity challenges and provision claims. There are also specialised claims such as rectification or proprietary estoppel in limited cases.
1. Lack of Testamentary Capacity
To make a valid will, the testator must have had legal testamentary capacity - understanding the nature and effect of the document, the extent of their estate and the claims of potential beneficiaries. A challenge may be made if evidence suggests the testator lacked capacity when the will was made due to illness, cognitive impairment or other incapacity.
2. Undue Influence and Coercion
A will may be contested if someone exerted undue influence over the testator, such that the document reflects another person's wishes rather than the testator's own intentions. Undue influence involves pressure or manipulation that overcomes an individual's free will. Evidence can include controlling behaviour or isolation of the testator.
3. Lack of Knowledge and Approval
A testator must know and approve the contents of their will. A challenge can arise where there is evidence that the testator did not fully understand the document they were signing or was unaware of its terms at the time of execution.
4. Lack of Valid Execution
The Wills Act 1837 sets out strict formalities for executing a valid will. If these requirements were not met - for example, if the will was not signed in the presence of two independent witnesses - the will may be challenged as improperly executed or invalid.
5. Fraud, Forgery and Clerical Errors
Claims can be brought where a will is forged, fraudulently altered, or contains clerical errors that misrepresent the testator's instructions. Separate claims for rectification can be made under the Administration of Justice Act 1982 when a will fails to reflect the testator's true intentions due to drafting mistakes.
6. Lack of Reasonable Financial Provision
Even if a will is valid, certain individuals can challenge it on financial grounds if they have not been reasonably provided for. Under the Inheritance (Provision for Family and Dependants) Act 1975, eligible claimants (such as spouses, children, former spouses in some circumstances, and financially dependent cohabitants) can seek court‑ordered provision from the estate. The court may order lump sums, specific assets or ongoing payments.
Who Can Contest a Will?
Not everyone has standing to challenge a will. The rights depend on the type of claim:
- Validity challenges (such as lack of capacity, execution or undue influence) can be brought by anyone with a sufficient interest in the estate, including beneficiaries, close relatives or persons affected by the will's terms.
- Inheritance Act claims are limited to specific categories - spouses, civil partners, children, former spouses (in limited circumstances), cohabitants with two years' cohabitation and other financial dependants.
The Legal Process
1. Seek Early Advice and Evidence
Contesting a will often involves gathering evidence such as medical records, witness statements and contemporaneous documentation showing capacity, influence or intent. Early legal advice helps shape the claim and identify pertinent documents before assets are distributed. Delay can weaken a case.
2. Enter a Caveat or File a Warning
To prevent probate being granted before a claim is prepared, a caveat can be lodged. If probate has already been applied for or granted, a warning or “appearance” can indicate a challenge to the court and other parties.
3. Claim Under the Appropriate Legal Framework
Depending on the grounds, a claim is issued in the appropriate court:
- Inheritance Act claims are brought within six months of the grant of probate or letters of administration. Courts may exceptionally extend this timeframe where justified.
- Validity challenges (capacity, undue influence, execution) have no strict statutory deadline, but delay is strongly discouraged because it can prejudice evidence and distribution.
4. Alternative Dispute Resolution and Negotiation
Before or during litigation, parties may attempt mediation or negotiation to resolve disputes without a contested hearing. This can reduce costs and preserve family relationships where possible.
5. Court Proceedings and Orders
If the dispute proceeds to the courts, a judge assesses the evidence and determines outcomes:
- Declaring all or part of a will invalid.
- Ordering rectification or construction of the will.
- Making provision under the Inheritance Act, which may alter how the estate is distributed.
Successful claims can lead to redistribution of assets or financial awards from the estate.
Time Limits and Limitation Rules
Different challenges have different timeframes:
- Inheritance Act claims: Must be made within six months of the grant of probate. Extensions are rare and granted only in exceptional cases.
- Validity challenges (capacity, undue influence, execution): No strict statutory deadline, but claims should be brought promptly to avoid disputes with estate distribution and loss of evidence.
- Rectification claims: Normally must be brought within six months of the grant of probate.
If assets have already been distributed, a claimant may seek recovery from beneficiaries, but such claims are more complex and fact‑specific. Acting early remains important.
Practical Considerations and Risks
Challenging a will can be expensive and emotionally demanding. Courts follow the general principle that costs follow the event - the losing party may be ordered to pay the winner's legal costs unless otherwise agreed. Settlements or negotiated agreements sometimes resolve disputes without full litigation. Specialist legal advice is essential when considering a challenge.
Common Questions
Can I contest a will if I am not mentioned?
Yes, but your eligibility depends on the grounds. For financial provision claims under the Inheritance Act, only certain categories of people (such as spouses, children and dependants) may bring a claim. For validity challenges, anyone with sufficient interest and evidence may proceed.
Is there a strict deadline to contest a will?
For Inheritance Act claims, the deadline is generally six months from the grant of probate. Other claims do not have strict statutory deadlines, but delay weakens a case.
What if the executor has already distributed assets?
Contesting a will after assets have been distributed is more complex. You may need to pursue orders to recover assets from beneficiaries, which can be difficult and depends on the circumstances. Early action, such as entering a caveat or warning, is usually recommended.
Key Takeaways
Contesting a will in England and Wales involves specific legal grounds, procedures and time limits. Challenges can be based on the will's validity - including lack of capacity, undue influence or improper execution - or on financial provision under the Inheritance (Provision for Family and Dependants) Act 1975 when the will fails to make reasonable provision for an eligible claimant. Early legal advice, timely action and careful evidence gathering are critical to a successful claim. Courts can order changes to the distribution of an estate, but disputes are often complex, emotionally charged and costly, requiring specialist guidance and informed decision‑making.
