The three response options
For this Section 3 notice, within fourteen days of receiving it the adjoining owner can consent in writing; dissent and propose an agreed surveyor jointly with you; or dissent and appoint their own surveyor. No written consent within that period can give rise to a deemed dispute. Section 1 astride-boundary work has a different written-consent rule.
Appointment of surveyors
On dissent the matter enters the statutory surveyor process. There are two routes. The agreed-surveyor route uses one surveyor jointly appointed by both owners. The two-surveyor route appoints one for each owner, plus a Third Surveyor selected to resolve any disagreement. Fees depend on the scope, location and complexity, so request written estimates.
The Schedule of Condition
Before works commence the appointed surveyor(s) may inspect the AO's property and prepare a Schedule of Condition — a written and photographic record of its current state that can provide evidence if damage is alleged later.
The Party Wall Award
The Award is a legally binding document setting out the scope of works, working hours, access arrangements, methods, indemnities, and the responsibility for fees. Once served, it cannot be unilaterally changed. Either owner can appeal to the County Court within fourteen days.
Who pays?
The building owner ordinarily pays the AO's surveyor's reasonable fees, as well as their own. The Award itself sets out the apportionment.
