My new neighbour has moved in and immediately changed the boundary fence between our houses. In the deeds it's their responsibility, nothing was wrong with the old one but they wanted to raise the height, fair enough.
However, they have removed the top and bottom 'shared' posts at the ends of their boundary fence (which form part of front and rear fences), detached the brackets from my adjoining fence and replaced the wooden posts with concrete posts that only they can use. My front fence and rear fence are now 'loose' with no post to attach to.
I believe that as the shared posts formed part of the front and back fences they should have left them (see diagram). They could have left or simply replaced these posts and reattached my fence as previously. They are refusing to do this or anything to resolve amicably.
Fwiw I also can't put in an adjacent fence post to secure my existing fence as their new posts are concrete not wood, therefore the 'footing' underneath prevents another post being close.
As it stands my only option without their cooperation would be to move my front and rear fences a couple of feet forward or back, which is costly and will look stupid as we will no longer have a symmetrical fence line.
'T's on diagram denote who maintains each fence, orange dot is one of the two previously shared fence posts now replaced.
NB due to the central shared posts being removed my garden gate has also collapsed and my garden obviously not secure, my fence now flaps in the wind. I've been nothing but nice to them, so quite upset about their behaviour here.
