Does anybody know the rules on exactly what you have to pay for if your neighbour appoints a party wall surveyor in respect of your project? I believe costs have to be "reasonable" and you can challenge if they aren't, but I can't find an answer on when the liability to pay for their surveyor ends....
Our neighbour has appointed their own surveyor which is their prerogative and we will pay their costs for the party wall award as is required. However, they have been making things quite difficult/delaying and they are now directing lots of questions to our surveyor through their surveyor even after the Award has been finalised and signed.
My presumption was that we are liable for their surveyor's costs for the award and if there are any disputes. But I didn't think we would be liable for day-to-day queries during the build (it's a big project - probably 6-7 month build). I'm worried they are going to deliberately rack up their surveyor's costs as a way of punishing us for doing the works (they're not at all happy about the project and objected to planning but there is a back story as our house used to be owned by one of their family members).
We have good builders with solid insurance and they are under strict instructions to do everything they can to minimise disruption etc to the neighbours as I know building works aren't fun for anyone. But I don't want to pay for them to have a chat with their surveyor every week because they're annoyed that we're building an extension!
TIA!
