Contesting a Will in the UK: Your Complete Guide

Discovering you've been left out of a will—or that a loved one's final wishes seem suspicious—is distressing. But challenging a will is a serious step with specific legal requirements.

Two Types of Challenge

There are two distinct ways to challenge a will in the UK:

1. Contesting validity: Arguing the will itself isn't legally valid
2. Financial provision claims: Seeking reasonable provision under the Inheritance Act, even if the will is valid

These have different requirements, time limits, and implications.

Contesting the Validity of a Will

A will can be challenged on several grounds:

1. Lack of Testamentary Capacity

The person making the will must have understood:

• That they were making a will and its effects
• The extent of their property
• Who might reasonably expect to benefit
• That they were not suffering from any "disorder of the mind" affecting these matters

This is commonly disputed when someone had dementia, mental illness, or was very unwell when the will was made.

2. Undue Influence

If someone pressured or coerced the will-maker, the will may be invalid. This is difficult to prove—you must show actual coercion, not just persuasion or advice.

Warning signs include:

• Sudden changes to benefit a new person
• Isolation of the will-maker from family
• A person controlling access or information
• The will-maker being in a vulnerable state

3. Lack of Knowledge and Approval

The will-maker must have known and approved the contents. Suspicions arise when:

• Someone else prepared the will and benefits significantly
• The will-maker couldn't read the will (vision problems, language barriers)
• The will contains surprising or unusual provisions

4. Improper Execution

Strict formalities apply. A will is invalid if:

• It wasn't signed by the will-maker (or someone at their direction)
• Two witnesses weren't present when the signature was made or acknowledged
• Witnesses didn't sign in the will-maker's presence
• A witness or their spouse is a beneficiary (their gift fails, but the will remains valid)

5. Fraud or Forgery

If the will itself is forged, or if someone obtained the will through deliberate deception.

6. Later Will or Codicil

A later valid will or codicil may revoke or alter an earlier one.

Inheritance Act Claims

Even if a will is perfectly valid, certain people can claim they haven't received "reasonable financial provision." This is under the Inheritance (Provision for Family and Dependants) Act 1975.

Who Can Claim?

• Spouse or civil partner
• Former spouse (who hasn't remarried)
• Cohabitant of at least 2 years
• Children (including adult children)
• Anyone treated as a child of the family
• Anyone being maintained by the deceased

What the Court Considers

The court looks at:

• Financial needs and resources of the claimant and beneficiaries
• Size of the estate
• Physical or mental disability of the claimant
• Conduct of the parties
• Any obligations of the deceased to the claimant
• Any other relevant matter

Spouses are assessed differently—they're entitled to the provision a spouse would receive on divorce, not just maintenance.

Time Limits

Inheritance Act Claims

You must start proceedings within 6 months of the grant of probate. Courts rarely extend this, so act quickly.

Validity Challenges

There's no fixed time limit, but:

• Enter a caveat at the Probate Registry to prevent probate being granted while you investigate
• Delay makes gathering evidence harder
• Once assets are distributed, recovery is difficult

The Process

Initial Steps

1. Gather evidence: Obtain copies of the will, medical records, witness statements
2. Enter a caveat: Prevents probate being granted (lasts 6 months, can be extended)
3. Get legal advice: Essential for understanding your chances and options
4. Attempt mediation: Many disputes settle without court proceedings

Court Proceedings

If negotiation fails:

1. Issue a claim in the relevant court
2. Exchange evidence and witness statements
3. Attend case management hearings
4. Trial (if no settlement)

Most cases settle before trial, often at a mediation stage.

Costs and Funding

Will disputes can be expensive:

• Legal fees can run into tens of thousands of pounds
• If you lose, you may pay the other side's costs
• The estate pays its own legal costs, reducing what's available

Funding Options

• No win, no fee: Available for some Inheritance Act claims
• Legal expenses insurance: Check if you have cover
• After the event insurance: Protects against paying opponent's costs
• Litigation funding: Third parties fund cases in return for a share

What Are the Chances of Success?

Success depends heavily on the circumstances:

Stronger Cases

• Clear evidence of incapacity (medical records, witness statements)
• Obvious undue influence with evidence
• Technical execution failures
• Inheritance Act claims by spouses or minor children
• Claimants with genuine financial need

Weaker Cases

• Adult children claiming they were "unfairly" excluded
• Suspicion without evidence of undue influence
• Claims primarily motivated by family grievance rather than financial need
• Well-drafted wills by solicitors with capacity assessments

Alternatives to Court

Family Mediation

A neutral mediator helps family members reach agreement. Cheaper and preserves relationships better than litigation.

Negotiated Settlement

Beneficiaries can agree to vary the estate distribution without court involvement if all adult beneficiaries consent.

Deeds of Variation

Within 2 years of death, beneficiaries can redirect their inheritance. Sometimes used to avoid litigation by giving something to those left out.

Protecting Your Will From Challenge

If you're making a will and want to reduce challenge risk:

• Use a solicitor who keeps detailed attendance notes
• Get a medical capacity assessment if there's any doubt
• Explain your reasoning in a letter stored with the will
• Consider involving an independent witness
• Ensure proper execution with witnesses who'll be available to give evidence

Getting Legal Advice

Will disputes are complex and emotionally charged. Seek specialist advice early if:

• You believe a will is invalid
• You've been unexpectedly excluded or received less than expected
• You're an executor facing a challenge
• You're a beneficiary whose inheritance is being disputed

Many solicitors offer free initial consultations to assess your case.
