As of 13 August 2026, AI cannot check your UK commercial lease.

This still needs a person who signs their name to it.

What the alternative costsA solicitor's review is the relevant alternative; no price is provided in the available tool information.

If this goes wrong, you may sign a lease with an overlooked repairing, break, rent review, alienation or liability provision and discover the cost only after you are committed.

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 complete lease, including every schedule, plan, side letter, guarantee and licence referred to in it, and make sure the pages and clause numbers are visible.
    2. Gather the heads of terms, agreed rent and incentives, intended business use, proposed alterations, repair condition, break date, and whether you are the tenant or landlord.
    3. Paste or attach the lease and supporting documents to an AI tool, then paste the prompt above with your role, intended use and specific concerns filled in.
    4. Ask the tool to produce the clause-referenced summary, issue table and solicitor questions without making assumptions about missing documents.
    5. Compare every quoted clause and page reference against the original lease, and mark any missed schedule, incorrect quotation or unsupported assumption.
    6. Send the checked issue table, the full lease and the heads of terms to a UK commercial property solicitor, asking them to confirm the legal effect, risks and changes before you sign.

    Prompt

    Review the UK commercial lease pasted or attached below as a document-review assistant, not as a solicitor. Do not give definitive legal advice or say that any clause is enforceable. First summarise the lease in plain English, including the parties, premises, term, rent, deposit, service charge, insurance, repairs, alterations, use restrictions, assignment and subletting, break rights, renewal position, rent reviews, guarantor obligations, termination rights, dilapidations, compliance duties, indemnities, disputes and costs. For every point, quote the relevant wording or give a precise page and clause reference. Then produce a table with: clause reference, what it appears to do, why it may matter to the tenant or landlord, questions or risks to raise, and information needed to assess it. Flag apparent inconsistencies, missing schedules, undefined terms, unusual obligations and provisions that should be checked against the heads of terms. Separate text that is clearly present from assumptions and questions. Do not invent facts, legal rules, market practice or financial figures. End with a short list of questions for a UK commercial property solicitor. Lease: [PASTE OR ATTACH LEASE]. My role: [TENANT OR LANDLORD]. Intended use: [BUSINESS USE]. Agreed commercial points or heads of terms: [PASTE IF AVAILABLE]. Specific concerns: [LIST THEM].

FAQ

Can ChatGPT review my commercial lease?
It can summarise the document, quote clauses and produce an issue list. It cannot reliably confirm the legal effect or commercial suitability of the lease, so a serious review needs a UK commercial property solicitor. This is not professional advice.
Is it safe to use AI to check a commercial lease?
Use it for document extraction and to prepare questions, not as the final check before signing. A missed break condition, repair obligation or liability provision can create a costly commitment that you may not discover until later.
What can AI find in a commercial lease?
It can identify and organise items such as rent, term, service charge, repairs, insurance, assignment, subletting, break rights and termination provisions. You still need a solicitor to assess whether the drafting works legally and whether the terms are acceptable.
Do I need a solicitor to review a commercial lease?
For a lease you may sign, renew, assign or materially change, you should use a UK commercial property solicitor. AI can make that review more efficient by preparing a clause-referenced summary and a list of questions, but it does not carry the legal responsibility.
