As of 13 August 2026, AI cannot value a property for probate.
This still needs a person who signs their name to it.

What the alternative costsA professional valuation by a suitably qualified property valuer is the alternative; no price is stated here.
If this goes wrong, the estate may use an unsupported figure in its probate or tax administration and need professional correction later.
What to actually do
Hand it to a person
The route this page recommends
Someone with a licence or accountable authority has to sign this before it counts.

Second choiceDo it yourself
The distant thirdA chat interface gets you a draft, but you cannot verify it yourself. That is the catch.
How to actually do it
- Open a document or note and gather the property address or area, property type, approximate size, rooms, tenure, lease information, known defects and any planning or restriction documents.
- Collect photographs showing the outside, every room, the garden or land, outbuildings, visible defects and any unfinished work, without including unnecessary personal information.
- Paste the prompt and the gathered facts into a chatbot, asking it to prepare a valuation brief and evidence checklist rather than a final probate figure.
- Compare every factual item in the chatbot's brief against the documents and photographs, deleting anything it has guessed or cannot trace to your material.
- Ask a RICS-qualified surveyor or suitably qualified probate property valuer to assess the property at the relevant valuation date and provide the figure needed for the estate.
- Give the valuer the checked brief, photographs, documents and any comparable-sale leads, then use the professional report for the probate and tax administration.
Prompt
Help me prepare information for a UK probate property valuation, but do not give me a final valuation and do not present an estimate as suitable for HMRC, probate or any legal filing. Using only the information I provide, create: 1. a concise property brief; 2. a list of missing facts that could affect the value; 3. a table of comparable-sale evidence, clearly separating verified facts from assumptions; 4. questions to ask a RICS-qualified valuer or other suitably qualified probate property valuer; and 5. a checklist of documents and photographs to gather. Flag anything that needs an on-site inspection, local market knowledge or professional judgement. Do not invent facts, comparable sales, dates, prices or legal requirements. Property details: [address or area, without unnecessary personal data]. Property type: [type]. Approximate size: [size]. Bedrooms and bathrooms: [details]. Condition: [details]. Tenure: [freehold or leasehold, if known]. Lease details: [details, if applicable]. Known defects or restrictions: [details]. Photographs or documents available: [list]. Relevant valuation date: [date of death or other required date].

What it gets wrong
- AI cannot inspect the property or see defects, alterations and location factors that are absent from your material.
- AI cannot establish a defensible open market value at the relevant valuation date.
- AI cannot take responsibility for a figure submitted in probate or to HMRC.
- AI cannot replace the local market judgement and professional evidence behind a formal valuation.
- A polished estimate can look authoritative even when its comparable evidence is incomplete or invented.
What makes this a NO: legal accountability, verification cost and stakes of error.

FAQ
- Can ChatGPT value a house for probate?
- No, not reliably or with responsibility for the figure. This is not professional advice. It can organise your property information and help you prepare questions, but a serious case needs a RICS-qualified surveyor or suitably qualified probate property valuer.
- Do I need a professional valuation for probate?
- You need appropriate professional evidence where the property value is uncertain, disputed, unusual or material to the estate. A qualified valuer can assess the property and provide a report that you can use in the relevant administration.
- Can AI estimate the value of an inherited property?
- AI can produce a preliminary estimate from information and comparable sales that you supply, but it can miss condition, location and valuation-date issues. Treat it as preparation only, not as the figure for probate or HMRC.
- What information does a probate property valuer need?
- Gather the address or area, property type, size, room details, tenure, lease information, condition, defects, alterations, photographs and relevant documents. Tell the valuer the valuation date and disclose anything that could affect market value.
