You essentially have two options when replying to a party wall notice: consent or dissent. If you choose the former, then your neighbour proceeds with the works and no surveyors are appointed under the Act. However, if it is the latter, then you can appoint your own surveyor or both neighbours jointly appoint an agreed surveyor (who acts on behalf of both parties) for an award to be drafted and served. All surveyors in the party wall process are required to be impartial with the role of resolving disputes. This is because their appointment is statutory. In terms of consent and dissent, this is completely up to you. You will have to weigh up how much you trust your neighbours and whether you require the extra protection of an award.
