Short answer
Prepare the disputed will, earlier wills, probate status, caveat papers, solicitor file if available, medical and care records, relationship history, evidence of pressure or isolation, estate summary and a clear chronology.
Quick checklist
Start with these
Start With The Will And Probate Position
Put the disputed will, any codicils, earlier wills and probate position at the front of the pack. The first review should show whether a grant has been applied for, stopped by caveat, issued or challenged in proceedings.
If there is a caveat, warning, appearance or probate claim, include those papers and all dates.
- Disputed will, codicils and earlier wills.
- Grant, probate application, caveat, warning or appearance papers.
- Estate summary, asset information and family tree.
- Solicitor file, will instructions or attendance notes if available.
- Existing claim, letter before action, mediation or court order.
Evidence About Pressure And Circumstances
Undue influence allegations are serious and fact-sensitive. A useful pack identifies who is alleged to have applied pressure, what happened, when it happened and how it affected the will-making process.
Keep first-hand evidence separate from second-hand concern. Include names of potential witnesses and explain how each person is connected to the deceased.
- Messages, letters, diary entries or notes about pressure or control.
- Evidence of isolation, dependency, care arrangements or financial control.
- Witness details for family, carers, friends, professionals or neighbours.
- Medical, capacity, medication and care records where relevant.
- Evidence explaining any major change from previous wills or lifetime promises.
Ask For A Defined Probate Review
A barrister may be asked to advise on evidence, merits, caveat response, pleadings, mediation preparation, settlement risk or representation at a defined hearing.
Some probate disputes need solicitor support for estate administration, issuing proceedings, service, disclosure, correspondence, asset preservation or ongoing litigation conduct.
Important Cautions
This guide is general information only. It is not advice that a will is invalid or that a probate step should be taken.
Probate disputes can create costs risk and urgent grant or estate administration issues. Deadlines and court papers should be checked promptly.
Source/review note: checked against GOV.UK probate caveat guidance and BSB Public Access materials in September 2026. Undue influence, capacity, knowledge and approval, limitation, caveats, costs and estate administration issues need specialist probate review before publication.

Undue Influence Will Dispute Barrister Evidence Guide FAQs
Is suspicion enough to challenge a will?
No. A barrister will usually need documents and witness evidence that explain the concern. This guide does not assess whether a challenge has merit.
Should I enter a caveat?
This needs case-specific advice. Caveats can affect probate and may lead to legal action and costs, so the grant position and urgency should be checked promptly.
Can a barrister help without a solicitor?
A probate barrister may advise, draft or represent in a defined task where Direct Access is suitable. Complex estate administration or litigation conduct may require solicitor support.
