Neighbour wants me to pay his legal fees

Thank you all once again for your sound advice. Now I can think rationally again I will try to negotiate and pony up the cash if I fail. Experience teaches me acting in haste or anger is the worst thing I can do. I'll let you know the outcome, but it may take a while...

Thank you all again for your advice, it was very helpful.

When I had calmed down I asked my neighbour what was going on, and he genuinely didn't know. It seems his solicitor suggested this (as it is not an unusual arrangement) and he probably didn't hear as he is a little deaf. After considering the issue for a few days he called by and said he would pay his own fees, to my huge relief.

Which only goes to prove a little faith and goodwill goes a long way. I am so happy we did not end up in dispute with each other.

Thanks again!

Great to hear it all work out in the end and thanks for letting us know the outcome
