My neighbours have just served me a party wall notice. It's a single story extension; I have seen the plans and have no objections. But... the letter I have received asks me whether, in the event of a dispute, I would be willing to agree to the appointment of an agreed surveyor. Details of agreed surveyor to be advised if a dispute arises.
This has surprised me. I thought the party wall surveyor was meant to be appointed as a matter or course, before – not after – any disputes arose. Isn't the idea that they come and take pictures of my property etc before the work starts? Otherwise if a dispute arose because of damage to my property, how would I prove that there was no sign of the damage before the building works?
