We're using an off-the-peg loft conversion company to do an L-shaped conversion to our mid-terrace house.
We have served notice of this to both neighbours, but only have the contact details of one neighbour's brother (he helped her do it up and now she rents it out), who immediately demanded that we pay a £1,500 "donation" to use the wall they built for their loft conversion, otherwise he will "make it very difficult for us to proceed" by appointing surveyors etc. We would obviously rather not get into double/triple surveyor territory but he has us over a barrel as costs could spiral far beyond his named price. Especially galling as our builder (and surveyor helpline) said the wall in question wouldn't have cost more than £1,000 to build from scratch so we shouldn't pay more than 50% of that...
Anyway, we managed to get him down to a £1,000 donation, but he is now saying we need to pay the money direct to him rather than his sister as she is abroad and 'offline'. The whole thing seems really dodgy. How can we make sure this money is going to the legal owner of the house without him throwing his weight around and making things difficult for us? Is there any legal framework within which we can award the money (would obv also like him to pay tax on it!)? And is he allowed to sign the party wall agreement on his sister's behalf?
Thanks and sorry if it doesn't make sense. I'm seething and all rational thought is jumbled.
