IMO, you are closed minded because despite surveyors, lawyers and just plain old regular people telling you to the contrary and trying to show you the opposite side of the coin.. you are steadfastly refusing to give an inch. which might serve you brilliantly as a lawyer, but as a neighbour, it is not going to get you very far
there are 400 messages on this thread, and they all agree with each other, not with you. so at the end of the day, it might be wise to take a step back and wonder if maybe, , just maybe, this is not quite how you are seeing it?
that maybe, this neighbour , who is a litigator, and already pissed off , is not going to roll over and play dead
there has been a lot of helpful and sound advice, from at least one lawyer and a chartered surveyor
lots of links have been posted to relevant legal info
yet you persist in ignoring it all
perhaps you dont; class the advice on this thread as useful or helpful because it does not agree with your opinion
so on all of those things, i say you are closed minded.
i am sorry that you witnessed an assualt, that must have been very upsetting.
