As of 13 August 2026, AI can only partly calculate the value of your estate for UK probate.

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, chat-fluent skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open the GOV.UK guidance on applying for probate and create a folder for the estate documents, keeping the date of death and the deceased person's full name on the folder.
   2. Gather bank and building society statements, investment statements, property information, vehicle details, insurance and pension correspondence, business records, relevant gift records, foreign asset documents, funeral invoices and evidence of debts.
   3. For each asset or liability, record the owner, account or reference, source document, relevant date and the figure shown, without replacing a missing figure with an estimate.
   4. Obtain current written valuations for property, valuable personal possessions, vehicles, businesses or other assets that cannot be supported by a statement, and keep each valuation with its source and date.
   5. Paste the inventory and document text into the copyable prompt, replacing the bracketed slots, and ask the chatbot to produce the worksheet and arithmetic.
   6. Compare every total and source figure in the response with the original statements and valuations, correct transcription errors, and mark every missing or uncertain item instead of accepting an estimate.
   7. Send the completed worksheet and the flagged questions to a solicitor or probate professional before using the figures in the probate application or any inheritance tax process.

   Prompt

   Help me prepare a UK probate estate valuation worksheet from the information below. This is not professional advice and you must not make legal, tax or valuation decisions for me.
   
   Use only the facts and documents I provide. Do not invent, estimate or fill gaps with typical values. Keep the figures as at the date of death: [DATE OF DEATH]. Record the source and date for every figure.
   
   Create a table with these columns: asset or liability, owner, description, source document, value at the date of death in pounds, confidence or missing information, and questions for a solicitor or probate professional. Separate:
   1. property and land;
   2. bank and savings accounts;
   3. investments and shares;
   4. pensions and insurance policies;
   5. vehicles and personal possessions;
   6. business interests;
   7. debts and funeral expenses;
   8. jointly owned assets;
   9. gifts or transfers that may need professional review;
   10. foreign assets, trusts or other unusual items.
   
   Calculate, showing the arithmetic, the gross total of assets, the total of liabilities, and the net estate total using only confirmed figures. Do not decide which assets belong in the probate value, which are exempt, or whether inheritance tax is due. Instead, flag those points for a solicitor, probate professional or HMRC process. Identify duplicate entries, conflicting figures, missing statements and figures that need an independent valuation. End with a short document checklist and a list of specific questions to take to the professional handling the estate.
