As of 13 August 2026, AI cannot challenge a will in the UK.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface gets you a draft, but you cannot verify it yourself. That is the catch.

   How to actually do it

   1. Open the GOV.UK probate and wills information relevant to your jurisdiction, and note whether probate or another estate process appears to have started.
   2. Gather the will, any earlier will you have, letters or emails about the will, probate correspondence, and records relevant to capacity, pressure, fraud or how the will was made.
   3. Write a dated account of what happened, separating what you personally saw from what someone else told you, and add the names of possible witnesses.
   4. Paste the account and document text into the prompt, stating the jurisdiction and redacting unnecessary personal data.
   5. Ask the chatbot to produce the chronology, document list, disputed-fact list and solicitor questions specified in the prompt.
   6. Compare every date and quotation in the output with the original papers, then correct the chronology before sharing it.
   7. Send the corrected summary and document list to a solicitor who handles contentious probate or will disputes, and ask about urgency, evidence, procedure and likely costs.

   Prompt

   I am considering challenging a will in England and Wales, Scotland or Northern Ireland: [jurisdiction]. This is not professional advice. Do not tell me that I have a valid claim and do not invent facts, deadlines, legal authorities or costs. Based only on the information and documents I provide, do the following: 1. separate confirmed facts, disputed facts and unknowns; 2. create a dated chronology; 3. list the documents and witnesses that may be relevant; 4. identify questions and possible issues for a UK solicitor to assess, without deciding the legal merits; 5. flag information that may be urgent to preserve or obtain; 6. draft a concise factual summary I can send to a solicitor. Quote or label the source of each factual point, mark uncertainty clearly, and tell me what you cannot assess. Here is my information and the documents I can share: [paste information or document text].
