Party walls selection of the third surveyor
In party wall procedures, the third surveyor has a powerful but rarely used role. One of the first duties of the appointed surveyors is to select a third surveyor, but current protocol does not require the third surveyor to be notified of this appointment as in most cases he or she will not be required.
Either of the surveyors or the parties may call upon the third surveyor to determine disputed matters. The third surveyor can either act with one of the other two surveyors to make the award or, where a specific matter in dispute is referred to him or her, may make his or her own award.
This document is a sample letter for proposing the selection of a third surveyor.
