Introduction: Understanding Will Challenges in the UK

Wills are essential documents that allow individuals to set out how they want their assets distributed after death. But what happens when a will is challenged? In the UK, disputes over wills—whether due to family conflict, suspicions of undue influence, or concerns over legal validity—are becoming increasingly common.

In this guide, we’ll break down:

  • Why wills are contested
  • Who can challenge a will and on what grounds
  • The legal process of disputing a will
  • What happens to the estate while a dispute is ongoing
  • How to avoid will disputes in the first place

Whether you’re considering contesting a will or you’re an executor defending one, this article will help you understand your rights and what to expect.


1. Can a Will Be Challenged in the UK?

Yes, a will can be challenged in the UK. This process is commonly referred to as “contesting a will” or launching a will dispute. However, there are strict rules and time limits governing how and when a will can be challenged.


2. Who Can Contest a Will?

The following people typically have legal standing to contest a will:

  • Close family members (e.g. spouse, child, stepchild, cohabiting partner)
  • Beneficiaries of previous wills
  • Individuals who were financially dependent on the deceased
  • People who would benefit under intestacy rules if the will were invalid

3. Legal Grounds for Contesting a Will

To challenge a will successfully, one or more of the following legal grounds must be established:

a. Lack of Testamentary Capacity

The deceased was not of sound mind at the time of making the will.

b. Lack of Proper Formalities

The will was not signed and witnessed in accordance with the Wills Act 1837.

c. Undue Influence

Someone pressured or coerced the deceased into making the will.

d. Fraud or Forgery

The will is fake or the signature was forged.

e. Lack of Knowledge and Approval

The deceased didn’t understand or approve of the contents of the will.

f. Inheritance Act 1975 Claims

If someone was financially dependent on the deceased and has been unfairly excluded or inadequately provided for.



4. Time Limits for Challenging a Will

Each type of claim has a different time limit:

Claim TypeTime Limit
Inheritance Act (1975)6 months from probate
Fraud or forgeryNo time limit
Contesting validity (e.g., undue influence)As soon as possible
Beneficiary disputesDepends on nature of claim

⏰ Top tip: Act quickly. If probate has already been granted, the estate may begin to be distributed.


5. The Process of Challenging a Will in the UK

Here’s what happens if someone decides to dispute a will:

Step 1: Entering a Caveat

A caveat is filed at the Probate Registry to stop the grant of probate while the challenge is investigated. This lasts for 6 months but can be extended.

Step 2: Legal Advice and Mediation

Solicitors typically encourage early resolution through negotiation or mediation.

Step 3: Evidence Gathering

This may include medical records, witness statements, and previous versions of the will.

Step 4: Court Proceedings (If Required)

If no agreement can be reached, the case proceeds to court for a judge to decide.


6. What Happens to the Estate While a Will Is Contested?

If a caveat is in place:

  • Probate is delayed
  • Assets cannot be distributed
  • Executors must pause administration
  • Costs and legal fees can reduce the value of the estate

Executors have a duty to remain neutral during disputes and act in the estate’s best interest.


7. Real-Life Scenario: A Will Dispute Over Undue Influence

Case study (fictionalised for educational purposes):

Mr. Evans, a widower in his late 80s, left the majority of his estate to a neighbour who helped him with shopping. His two adult children were shocked, as previous wills had split the estate between them. Suspecting undue influence, they challenged the latest will.

After gathering medical records and neighbour testimonies, it was found Mr. Evans had early-stage dementia and likely did not understand the implications of the new will. The court ruled in favour of the children and reinstated an earlier valid will.
