Survey finding
Party wall matters flagged in your survey
Party wall issues often come up in conveyancing rather than a structural survey, but surveyors can flag visible works that should have had formal notices. This page explains what to ask and where the conversation belongs.

Finding
Party wall matters
What this usually means
Party wall matters arise when works affect a wall or structure shared with a neighbouring property. Under the Party Wall etc. Act 1996, certain works (extending, excavating near, or altering a party wall or boundary) require serving formal notice on adjoining owners. If an agreement was not obtained when works were done, the buyer may inherit the liability.
Why it matters
Unauthorised notifiable works can create legal exposure, complaints from neighbours, and complications on resale. Solicitors typically raise party wall on the standard forms, but a surveyor may flag it if works are visible. It is mainly a conveyancing and neighbourly issue rather than a structural one.
Ask your surveyor
- Check:Are there visible signs of extension or alteration works that would have required party wall notices, and did the seller produce any party wall awards or agreements?
- Check:Is there evidence of works affecting shared or boundary walls that look recent or undocumented?
Ask the seller
- Check:Did you carry out any works that required a party wall notice under the 1996 Act, and do you have a party wall award, if so?
- Check:Have you received any complaints or notices from neighbouring properties about your works?
Next steps
- •Raise the party wall question explicitly with your solicitor, who can review the seller's form answers and request documents.
- •If no party wall award exists for notifiable works, take legal advice on whether retrospective consent or indemnity insurance is appropriate.
