At war with my neighbours AIBU to think it' may not be resolvable?

[neighbourwars]

So we've all fallen out with one of our neighbours. When I say "we" I mean my family who live one side, the neighbours the other side, the family that back onto his back garden and two other families in our l terrace of 5 house.
I can't say too much because it very outing, and if I put it in writing I doubt you'd believe me but I think its fair to say that amongst other things he is very quick to threaten legal action against all of us for fairly trivial things e.g. feeding the birds and that this upsets people.
Anyway we now largely ignore him. But one of my other neighbour is now deeply embroiled in a war with him. Now the police are involved. It's beginning to make everyone rather tense especially with this lockdown, we iive in village and it's just not possible to not see him.
Has anyone ever managed to successfully resolve a conflict with their neighbour? If so how? I don't want to be his best friend but this is becoming silly.

I would say definitely mental health issues. I would go to the police and make a detailed statement. It will help your other neighbors as well and police may take the whole situation more seriously. Even the vague details you mention would really frighten me.

look on the bright side; all those letters for solicitors (if they really are) will be cost him a bomb

@yellowfishes
If all the relevant details are "too outing" I'm not sure how you expect anyone to advise you
Was just thinking the same.
How are any of us supposed to know if YABU or YANBU with such a vague book post?!

I used to date a lawyer who did a lot of neighbourhood dispute work.

Totally anecdotally, it seemed once a dispute got to a certain level (and that level was before lawyers were involved) it would never be resolved. Even ones that went to court with a judge deciding, left residual bad feeling.

He will have to disclose the issues with neighbours when he tries to sell. Hopefully he will eventually move because the ramifications for the rest of you are probably worse. Any of the neighbours would need to disclose the issues in order to sell and as no one is immune there is a strong likelihood that anyone buying a house neighbouring him would also become embroiled. You all therefore have a vested interest in trying to get along or resolve in one way shape or form or the financial implications could be huge.
