How to organise the first pack
- Put the disputed will and probate status first.
- Add earlier wills and documents showing changed intentions.
- Separate capacity, execution, influence and fraud-related evidence.
- Include caveat, warning, claim or court papers if any.
- Explain the outcome being considered and the work needed.
Start With The Will And Probate Status
The first pack should include the disputed will, any codicils, earlier wills and a short note explaining why validity is questioned. The reason may involve capacity, execution, knowledge and approval, undue influence, fraud, revocation or another issue.
The enquiry should also say whether probate has been applied for, granted, stopped by a caveat, warned off or already disputed in proceedings.
Documents To Gather
A barrister will usually need documents showing how the will was made, what the testator understood and what changed from earlier estate plans.
- Disputed will, codicils, earlier wills and letters of wishes.
- Solicitor or will-writer file, attendance notes and draft documents if available.
- Medical, care, capacity, medication and dependency evidence where relevant.
- Witness details, family correspondence, messages and notes about instructions.
- Estate summary, asset list, executor details and beneficiary positions.
- Caveat, warning, appearance, claim, order or probate registry documents if any.
How A Barrister May Help
A probate barrister may advise on evidence, merits, pleadings, mediation preparation, settlement, caveat response or representation at a defined hearing.
Some probate disputes need solicitor support for estate administration, issuing proceedings, service, disclosure, correspondence, preserving assets or ongoing litigation conduct.
Review Notes For Sensitive Evidence
This guide is general preparation information only. It does not decide whether a will is valid, whether a caveat should be entered or whether proceedings should be started.
Will validity disputes can carry costs risk and may need urgent review if a grant, distribution or court deadline is approaching.
Avoid delays
What not to send first
- Sending allegations without the will and earlier estate documents.
- Leaving out probate status, caveat papers or grant information.
- Assuming family disagreement is enough to invalidate a will.
- Ignoring costs, limitation, distribution or court-order deadlines.
Source/review note: checked against GOV.UK probate caveat guidance and BSB Public Access guidance in August 2026. Testamentary capacity, execution, knowledge and approval, undue influence, limitation and costs issues need specialist probate review before publication.

Will Validity Barrister Evidence Guide FAQs
What evidence matters in a will validity dispute?
The will, earlier wills, instructions file, execution evidence, medical records, witness accounts and estate chronology are usually central.
Should I enter a caveat before asking for advice?
This guide cannot answer that. Caveats can affect probate and costs, so get case-specific advice quickly if a grant or deadline is approaching.
Can a barrister advise executors and beneficiaries?
A barrister may advise executors, beneficiaries or potential claimants where there is no conflict and the work is suitable for Direct Access.
