See obligatory diagram.
i can home today to find that my neighbour has put a new fence up and taken part of my garden. The blue area is my garden, grey is neighbours and the red part has now been fenced off.
the area is definitely mine. I’ve even shown a copy of the plans from when the house was built to the neighbour and his response was “anyone could have drawn that”. It’s a document that is signed and stamped FGS.
neighbour moved in 8 years ago so doesn’t have an adverse possession claim. There was previously a hedge there which was removed before neighbour moved in. 2/3 of the garden is a fence. Neighbour has extended that fence in a straight line rather than the boundary. We both own in case relevant.
where do I go from here?
