Third-Party Walls

What is a Third-Party Wall Notice and Agreement?

A third-party wall notice and agreement aren’t formal terms under the Party Wall etc.Act 1996. Please see our section on Party Wall Notices for information on Notices. 

Typically, in the context of party wall matters, there are two involved parties: the building owner proposing the work and the adjoining owner(s) whose property might be affected by the construction.

However, the involvement of additional parties or entities not directly tied to the properties in question might sometimes occur. For instance, if a tenant wishes to undertake construction that impacts a party wall, they might become a third party in the process. In such cases, their involvement and consent might be necessary, hence the term “third party wall agreement,” although it’s not a standard designation within the Act.

The Act primarily focuses on the rights and obligations of the building owner and the adjoining owner(s), but additional parties might become involved due to their interest or involvement in the properties affected by the proposed construction.
