A clear, authoritative guide to how to challenge a will in England and Wales, explaining legal grounds, procedures, time limits, caveats, evidence, mediation, court claims and practical steps for contested probate and Inheritance Act claims.

Challenging a will involves legally questioning whether a person's testamentary document is valid, or whether it makes reasonable financial provision for certain family members or dependants. In England and Wales, there are defined legal routes for contesting a will, which depend on the grounds you rely on and the outcome you are seeking. This guide explains the legal framework, procedures, time limits, and practical steps for challenging a will, drawing on up‑to‑date UK law and authoritative sources.
When and Why You Might Challenge a Will
A will challenge (also known as a contested probate matter) occurs when someone disputes all or part of the testamentary document submitted for probate after a person's death. People challenge wills for two broad reasons:
- Validity issues, where there are legal concerns about how the will was made; and
- Financial provision issues, where the will does not make reasonable provision for certain family members or dependants.
Both types of challenge can lead to court proceedings if they cannot be resolved through negotiation or alternative dispute resolution.
Legal Grounds for Challenging a Will
You cannot challenge a will simply because you disagree with its contents. There must be recognised legal grounds:
1. Lack of Testamentary Capacity
The person who made the will (the testator) must have had the required mental capacity at the time the will was signed. This means understanding the nature of the document, the extent of their estate, and the effect of the provisions. Evidence such as medical records may be used to support a claim that capacity was lacking.
2. Undue Influence or Coercion
If someone exerted pressure on the testator to make or change the will in a way that does not reflect their true intentions, this can form a basis for challenge. Influence must be significant enough to undermine free will.
3. Lack of Knowledge and Approval
A valid will requires that the testator knew and approved its contents. If they were unaware of what they signed (for example, because they could not read and were not properly assisted), this may be challenged.
4. Improper Execution
The Wills Act 1837 sets out strict rules for execution: the testator must sign the will, and two independent witnesses must also sign in the testator's presence. If these formalities were not met, the will may be invalid.
5. Fraud or Forgery
A will (or part of it) that has been fraudulently altered, forged, or created without the testator's consent is invalid. There is no fixed time limit for bringing claims based on fraud, but delay can weaken evidence and practical prospects of success.
6. Rectification and Construction Claims
Under the Administration of Justice Act 1982, certain errors in drafting that do not reflect the testator's intention may be corrected by the court. These claims typically must be brought within six months of the grant of probate.
Route for Financial Provision Challenges
A separate legal route exists under the Inheritance (Provision for Family and Dependants) Act 1975 for those who believe the will (or the intestacy rules if there is no will) does not make reasonable financial provision for them. Eligible claimants include spouses, civil partners, former spouses (who haven't remarried), cohabitants of at least two years, children, and other dependants.
This route is not about invalidating the will but about adjusting what the estate provides for the claimant. The court can order lump‑sum payments, asset transfers, or other appropriate remedies to ensure reasonable provision.
Step‑by‑Step Process to Challenge a Will
Step 1: Assess Your Grounds and Eligibility
Determine whether your concern relates to validity or financial provision. Validity challenges require evidence specific to the legal ground invoked. Financial provision claims require that you fall within the categories under the Inheritance Act.
Step 2: Seek Legal Advice Early
A solicitor experienced in contentious probate can help evaluate your case, suggest the appropriate claim route, and advise on evidence and procedure. Early advice increases the likelihood of protecting your rights and meeting deadlines.
Step 3: Lodge a Caveat (If Probate Is Not Yet Granted)
A caveat is a notice with the Probate Registry to prevent the grant of probate or letters of administration for six months. It gives you time to investigate your concerns and gather evidence before the estate is distributed. A caveat can often be renewed.
Step 4: Gather Evidence
Collect all relevant documents, including:
- Medical records relating to capacity
- Witness statements
- Drafts or previous wills
- Correspondence regarding the will's preparation
- Executor records
Your solicitor can request a copy of the will file from the drafting solicitor, which often reveals important context and the testator's instructions.
Step 5: Attempt Negotiation or Mediation
Many inheritance disputes settle before litigation. Mediation allows parties to negotiate with the help of an independent mediator, often saving time and reducing legal costs.
Step 6: Issue Court Proceedings
If negotiation fails, your solicitor will prepare and issue proceedings in the appropriate court. The claimant must clearly state their grounds, evidence, and the remedy sought. Proceedings will involve disclosure of documents, exchange of witness statements, and possibly a trial.
Step 7: Judgment and Implementation
The court may:
- Declare the will invalid (in whole or in part), meaning distribution follows an earlier valid will or intestacy;
- Order rectification of the will's terms;
- Award financial provision under the Inheritance Act; or
- Dismiss the claim.
Implementation of a successful claim may involve recovering or redistributing assets.
Time Limits and Practical Considerations
Inheritance Act Claims
Claims under the Inheritance Act must usually be commenced within six months of the grant of probate or letters of administration. Courts have limited discretion to allow claims outside this period in exceptional circumstances.
Validity Challenges
There is no strict statutory time limit for challenging a will on grounds such as lack of capacity, undue influence, or improper execution. However, acting promptly is essential because:
- Delay reduces the availability and quality of evidence;
- Executors may have already distributed assets; and
- Courts are less likely to be sympathetic to late claims.
Caveat Period
A caveat prevents probate for six months, which can be extended if necessary. This provides crucial time to prepare your claim and notify interested parties.
Risks and Costs of Challenging a Will
Contesting a will can be expensive and stressful. Court proceedings involve legal fees, expert evidence costs, and possibly adverse costs if your claim fails. Negotiation or mediation may reduce these risks, but litigation remains costly and uncertain.
Common Questions About Challenging a Will
Can Anyone Challenge a Will?
No. Only individuals with a legitimate interest - such as beneficiaries or those eligible under the Inheritance Act - can bring claims. For validity challenges, you need evidence of a recognised ground. For financial provision, you must fall within the statutory categories.
Can a Will Be Challenged After Probate Is Granted?
Yes, but it's more difficult. If assets have been distributed, the court may need to address recovery and account for what beneficiaries have already received.
What Happens if My Claim Succeeds?
For validity challenges, the will may be set aside or partially invalidated. For financial provision claims, the court can order adjustments to the estate to provide reasonable support.
Key Takeaways
Challenging a will in England and Wales is a structured legal process involving specific grounds and procedures. Validity challenges can be based on lack of capacity, undue influence, improper execution, fraud, or errors. Financial provision claims under the Inheritance Act allow eligible claimants to seek reasonable provision when the estate does not meet their needs. Time limits apply to some claims, notably the six‑month window for Inheritance Act claims. Early legal advice, careful evidence gathering, and consideration of alternative dispute resolution are key practical steps. Court proceedings are often the last resort and may be complex and costly.
