Party Wall Guide for Adjoining Owners

Identify the building owner, the property, the proposed operation, the notice category and the intended start. Ask for clear drawings where the work or excavation relationship is difficult to understand.

Check whether all relevant owners have been addressed, particularly for leasehold buildings or multiple flats. A boundary uncertainty or unclear ownership can require legal advice in addition to party wall surveying. Keep the notice and record when it was received.

Written consent may be reasonable where the proposal is understood and concerns have been addressed. It should not be confused with planning permission or an agreement to give up unrelated rights.

Consider a recorded schedule of condition and clear contact arrangements even where you consent. Do not sign a document you do not understand, or assume an absence of reply gives you indefinite extra time.

For a dispute under the Act, both owners can appoint one agreed surveyor, who must act impartially in the statutory role. Alternatively, each owner can appoint their own surveyor, with the statutory arrangements for resolving matters between them.

The agreed-surveyor route may reduce duplication, but both owners need confidence in the appointment. Separate appointments may be appropriate for a complex case. Ask about competence, scope, communications and fees rather than assuming one option is always better.

The surveyor can address matters within the Act such as construction details, reasonable protection, working arrangements and access. A schedule of condition can provide an agreed baseline for later assessment of alleged damage.

The process does not replace the council's planning assessment and is not a general veto over development. Concerns about noise nuisance, trespass, boundaries or dangerous work may need separate routes and advice.

Keep records of communications and report suspected damage promptly through the agreed channels. Photograph the concern without entering an unsafe site. Let the appointed surveyor assess disputed matters rather than accepting an informal on-the-spot settlement under pressure.

If work begins without a required procedure, seek appropriate professional advice promptly. Do not assume the existence of planning permission resolves the issue or that a late informal document necessarily fixes it.
