I don't think there is an answer to this but it's worrying me.
We live in a small cul de sac of a handful of detached houses. We have a shared courtyard setting where we are all jointly responsible for the upkeep of the driveway should it ever need repairs.
The value of the houses at present is around £650K. A couple of years ago, the original owners of the house nearest the entrance from the road moved and a new family moved in. They take very little care of the outside of their house ( weeds, dirty garage door) and last year their 6 ft high fence which is runs half the length of the shared courtyard/ driveway almost blew over, so they have propped it up. It looks a mess.
We are worried that when we sell at some point, the fence will put buyers off as makes the small development look tatty.
Legally, it's not on shared land but on the boundary.
can we ever drop hints to them?
