10(4) Party Wall Surveyor Appointments
There are often scenarios where a homeowner (known as the building owner under the Party Wall etc Act 1996) would like to carry out construction works within their home. If the building owner undertakes construction works to their property that fall within the remit of the Party Wall etc Act 1996, they have a legal duty to serve a Party Wall Notice on the adjoining owner notifying them of these works. For example, excavation works can interfere with soil movement and possibly the foundations beneath. As a result, any such works may cause the adjoining owner to have structural or decorative damage to their property.
- Consenting to the works (with or without a Schedule of Condition Report).
- Dissenting to works and appointing their own Party Wall Surveyor.
- Dissenting to works and agreeing in the appointment of an ‘Agreed Surveyor’. An Agreed Surveyor means that one Surveyor acts on behalf of the Building Owner and the Adjoining Owner mutually and impartially.
If at this point no response is received, then the Building Owner or the Party Wall Surveyor acting on their behalf can serve a ‘10(4) Party Wall Notice’ under the Party Wall etc Act 1996 which is an additional Notice allowing the adjoining owner a final and further 10 days to respond to the Party Wall Notice. Within the 10(4) Notice it will usually state the date the original Party Wall Notice was served and further describe the works that will be taking place in the Building Owner’s property.
If a 10(4) Party Wall Notice has been served and there still isn’t a response form the Adjoining Owner, the Building Owner or Party Wall Surveyor acting on their behalf can now legally proceed with the appointment of Surveyor under Section 10(4) of the Party Wall etc Act 1996, which allows the Building Owner to appoint a Surveyor on behalf of the non-responsive Adjoining Owner(s).
The appointed 10(4) Party Wall Surveyor will act impartially and help agree the Party Wall Award on behalf of the non-responsive Adjoining Owner. The Surveyor will attempt to make contact with the non-responsive owner. If they do begin communication at this stage, then the procedure would follow a similar route to if the non-responsive Adjoining Owner had chosen to dissent and appoint their own Party Wall Surveyor.
If however, the Adjoining Owner still fails to communicate with the appointed 10(4) Party Wall Surveyor , then the Building Owner’s Surveyor and the appointed 10(4) Party Wall Surveyor will work together to carry out an external Schedule of Condition Report, then agree and serve a Party Wall Award which will govern the works the building owner is proposing to carry out.
