Will Dispute Letter: Free Template and What to Include

If you need to challenge validity of will citing lack of capacity or undue influence, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong will dispute letter should include.

What this letter needs to cover

• State the grounds for the challenge (lack of testamentary capacity, undue influence, fraud, or failure to comply with formalities)
• Reference the specific evidence supporting the challenge
• Put the executor on notice that a probate caveat may be entered
• Request a meeting to discuss the matter before legal proceedings are issued

Grounds for challenging a will's validity

Challenging a will is a serious step, generally based on specific legal grounds — lack of testamentary capacity at the time it was made, undue influence by another party, lack of proper knowledge and approval of the contents, or improper execution (not signed and witnessed correctly).

What to include before you send it

• Which specific ground you're relying on to challenge the will
• Any evidence supporting your concern — medical records for capacity issues, or circumstances suggesting undue influence
• A request that the estate not be distributed while this matter is resolved
• Confirmation of your intention to pursue this formally if not resolved

Why acting quickly matters enormously here

Once an estate has been distributed, unwinding this becomes far more complicated and costly — raising a genuine concern about a will's validity as early as possible, ideally before probate is granted or the estate distributed, significantly protects your position.

Frequently Asked Questions

What's the difference between challenging a will and making an Inheritance Act claim?
Challenging validity argues the will itself isn't legally valid; an Inheritance Act claim accepts the will's validity but argues it doesn't make reasonable financial provision for you — these are different claims with different tests.

Do I need a solicitor to challenge a will?
Given the complexity and evidential requirements involved, professional legal advice is strongly recommended for will validity challenges specifically.

Dear [Name],

Subject: Challenge to the will of [Name of Deceased]

I am writing about the estate of [Name of Deceased], who died on [Date of Death]. I understand you are acting, or plan to act, as personal representative.

I am challenging the validity of the will dated [Date of Will] because [choose: the deceased did not have the mental capacity to make a will when it was signed / the deceased did not know and approve its contents / the deceased was put under undue influence by another person / the will is the result of fraud / the will was not signed or witnessed correctly].

My evidence: [e.g. medical records showing a dementia diagnosis in [year] / the will was made shortly after [person] moved in and took control of the deceased's affairs].

Please:
• do not distribute any assets while this is resolved;
• send me a full copy of the will and any earlier wills; and
• give me the contact details of whoever prepared and witnessed the will.

[England, Wales and Northern Ireland: I may enter a caveat to stop a grant of probate being issued while this is resolved.]

I would like to meet to discuss this before any court proceedings. Please reply within 14 days.

Yours sincerely,

[Your Signature]
