Neighbour is chopping down trees in picture to make room for a fence. They told us they are planning on attaching it to the wooden posts of our parking space. This would leave us unable to open car doors once in there. They said they think we would have enough room, I disagree.
We are planning on moving the metal shed in the picture so the green car would be further back and the silver car door would need to open between he first and second posts.
Also the land on the right is not theirs but communal land so I'm not sure they even are able to erect a fence there - I think they are planning on edging it with fencing and making it into their garden as nobody else uses it.
Legally, are the posts ours and can we say no? Our deeds say the whole space is ours and the posts are on our concrete section. I'm so worried about it. I have issues associated with hyper mobility which means I cannot twist out in a small gap and also have car seats to contend with.
Any advice would be greatly appreciated
