This comprehensive guide explains how to contest a will in England and Wales. It clarifies the legal grounds for challenging a will, relevant time limits, the procedural options including negotiation and court claims, practical steps to take, risks involved, and answers to common questions. The article uses UK‑specific terminology - such as probate, Grant of Representation, Inheritance (Provision for Family and Dependants) Act 1975, intestacy, claim, court, solicitors, and tribunals - to make complex legal concepts accessible to novices while remaining credible for solicitors.
When Might a Will Be Challenged?
A will sets out how a person (the testator) wants their estates and assets distributed after their death. Normally, a validly executed will should be respected. However, there are legal circumstances in which a will can be contested - that is, formally challenged in court or through negotiation - either because the will is invalid or because the provision it makes is legally insufficient for someone with demonstrable financial need. Understanding when and how this can be done is crucial for anyone concerned about their rights following a testator's death.
Grounds for Contesting a Will
There are distinct legal reasons - or grounds - for challenging a will. These fall into two broad categories: validity challenges and financial provision challenges.
Validity Challenges
These arguments assert that the will itself is legally invalid and should be set aside or corrected by a court. Common grounds include:
1. Lack of Testamentary Capacity - The testator did not have the mental capacity to understand the nature and effect of the will at the time it was made. Medical evidence and witness statements may be required to support this.
2. Undue Influence or Duress - Someone exerted improper pressure on the testator to make or change the will in a way that does not reflect their true wishes.
3. Lack of Knowledge and Approval - The testator did not understand, or was not aware of, the contents of the document they signed.
4. Lack of Proper Execution - Wills must be written, signed by the testator, and witnessed properly under section 9 of the Wills Act 1837; failure to comply can invalidate the will.
5. Fraud or Forgery - The will (or signature) is forged or otherwise fraudulent.
If a validity challenge succeeds, the will may be declared invalid in whole or in part, potentially reverting the estate to a previous will or to the rules of intestacy.
Financial Provision Challenges (Inheritance Act Claims)
If the will is valid but fails to make reasonable financial provision for someone who has a legally recognised claim on the estate, that person may apply to the court under the Inheritance (Provision for Family and Dependants) Act 1975 (commonly known as the 1975 Act). This does not invalidate the will per se, but asks the court to adjust the distribution of the estate so that the claimant receives appropriate provision. Categories of potential claimants include:
- A spouse or civil partner of the deceased;
- A former spouse or civil partner (not remarried or in a new civil partnership in certain circumstances);
- A child of the deceased (including adopted, foster, or step‑children in some cases);
- A cohabitee who lived with the deceased for at least two years immediately before death;
- Anyone who was being financially maintained by the deceased.
The court assesses whether the estate's distribution makes reasonable financial provision for the claimant's needs compared with those of the beneficiaries.
When and How to Contest a Will
Before Probate Is Granted: Caveats
If you think you might contest a will and probate (also called a Grant of Representation) has not yet been issued, you may lodge a caveat at the Probate Registry to temporarily prevent the grant being made for six months. This gives you time to investigate and prepare your case. A caveat can be extended if necessary.
Time Limits
Different forms of will challenges have different time constraints:
- Inheritance Act claims must be issued within six months of the date of the Grant of Probate or Letters of Administration.
- For validity challenges based on lack of capacity, undue influence, lack of execution or fraud, there is no fixed statutory time limit, but acting promptly is strongly advisable because delay can weaken evidence and complicate recovery of distributed assets.
If you miss the six‑month deadline for an Inheritance Act claim, you must apply for the court's permission to proceed out of time, demonstrating good reasons for the delay.
Preparing Your Claim
- Gather Evidence - Assemble all relevant documents: the will, prior wills if available, medical records (for capacity), correspondence, and details of financial dependence or need.
- Establish Grounds - Determine whether you are pursuing a validity challenge, an Inheritance Act claim, or both.
- Seek Legal Advice - Specialist solicitors in contentious probate can assess merits, advise on procedure, and help prepare your claim.
- Issue a Claim - Validity challenges or Inheritance Act claims are commenced by issuing a claim in the High Court or County Court at Probate Registry as appropriate, following Civil Procedure Rules.
- Consider Alternative Dispute Resolution - Early negotiation or mediation can resolve disputes without costly court proceedings.
The Court Process
Most disputes start with letters before claim and, where possible, informal negotiations or mediation. If no agreement is reached:
- A court application is prepared and filed.
- The court will consider evidence and legal arguments from both sides.
- Hearings may be held, and witnesses may give testimony.
- The judge issues a decision.
In Inheritance Act cases, the court assesses financial needs against estate resources and the needs of beneficiaries. In validity challenges, the factual and legal issues focus on capacity, influence, execution, or fraud.
Claims may settle at any stage, including before trial. Professional solicitors or mediators often help negotiate settlements that reflect reasonable provision for claimants or confirm the will's validity.
Risks and Practical Considerations
Costs and Financial Risk
Contesting a will can be expensive, especially if a case goes to full trial. Legal costs may be awarded against the unsuccessful party, meaning you could be ordered to pay the other side's costs in addition to your own. Cost risks vary with complexity and length of proceedings.
Evidence Challenges
Validity challenges - particularly those based on mental capacity or undue influence - rely heavily on credible evidence such as medical records or witness statements. Delay in gathering evidence can weaken your claim.
Distribution of Assets
If assets have already been distributed following probate, even a successful challenge may make recovery more difficult, particularly if beneficiaries have spent or transferred assets. Acting early - ideally before probate or soon after - reduces this risk.
Common Questions
Can any relative contest a will?
Only certain categories have clear legal standing. Inheritance Act claims are limited to defined classes (spouses, children, dependants). Other challenges (capacity, formalities) generally require a legal interest in the estate and compelling grounds.
Is there always a six‑month deadline?
The six‑month limit applies to Inheritance Act claims. There is no statutory deadline for some validity challenges, but acting promptly is essential.
Is contesting a will the same as disputing an inheritance?
Not always. A contest based on the will's validity aims to set the will aside or correct it, whereas an Inheritance Act claim seeks financial provision without invalidating the will itself.
Key Takeaways
Contesting a will in England and Wales requires understanding the legal grounds and the procedural context:
- Validity challenges focus on issues like capacity, undue influence, lack of execution or fraud.
- Inheritance Act 1975 claims seek reasonable financial provision and must be issued within six months of a Grant of Probate.
- Acting promptly, gathering robust evidence, and seeking specialist legal advice improves your chances of a successful outcome.

Understanding your rights and the legal pathways available ensures you can consider appropriate practical actions when disputing a contested will.
