A party wall dispute surveyor is a specialist party wall surveyor with expertise in resolving disputes that arise under the Party Wall etc. Act 1996. While most party wall matters are handled amicably by a single agreed surveyor or two appointed surveyors working cooperatively, disputes can arise over the terms of a party wall award, alleged damage caused by building works, the scope of notifiable works, or the level of compensation. In these circumstances a party wall surveyor with specific dispute resolution experience is needed - including, in the most contested cases, appointment as the Third Surveyor whose decision is binding on both parties.
What they do
- Advise on disputed party wall notices and counter-notices
- Prepare contested party wall awards on behalf of one party
- Investigate disputed damage claims and prepare damage reports
- Act as Third Surveyor when two appointed surveyors cannot agree
- Advise on and handle retrospective party wall disputes
- Assist with appeals against party wall awards in the county court
- Provide expert witness reports in party wall litigation
- Advise on enforcement of party wall awards
When you need one
A party wall dispute specialist is needed when a party wall matter has become or is likely to become contested - whether over the terms of works, damage caused, or a procedural dispute under the Act.

Qualifications to look for
The Faculty of Party Wall Surveyors is the specialist professional body for party wall surveyors and is the primary quality indicator for party wall dispute expertise. FPWS members have demonstrated specialist knowledge of the Party Wall etc. Act 1996 beyond general RICS membership. For dispute work, look for surveyors with specific Third Surveyor experience. Check membership at fpws.org.uk.
All party wall surveyors should be RICS-chartered (MRICS or FRICS). RICS membership provides the professional framework, PII requirements and disciplinary standards that underpin party wall practice. Many party wall dispute surveyors are building surveying or general practice RICS members with additional party wall specialism.
How to find a reputable party wall dispute surveyor
Frequently asked questions
What happens if my neighbour refuses to appoint a surveyor?
If the adjoining owner dissents from a party wall notice but fails to appoint a surveyor within 10 days of the building owner's request to do so, the building owner may appoint a second surveyor on the adjoining owner's behalf. The two appointed surveyors then attempt to agree a party wall award. If they cannot agree, they refer the matter to the Third Surveyor (agreed in advance when the two surveyors were appointed) whose decision is binding.
Can a party wall award be appealed?
Yes. Either party may appeal a party wall award to the county court within 14 days of service of the award. The court may rescind or modify the award. Appeals must be made promptly - the 14-day time limit is strict. Given the short time limit it is important to take legal advice quickly if you believe a party wall award is wrong.
What is a Third Surveyor?
The Third Surveyor is agreed (not appointed) by the two party wall surveyors at the beginning of the process - typically when each surveyor accepts their appointment. The Third Surveyor acts as an arbitrator when the two surveyors cannot agree on any matter that falls to them. The Third Surveyor's decision on the referred matter is binding. In practice the mere existence of the Third Surveyor mechanism often encourages the two surveyors to reach agreement.
