For the fence that runs along the back of a house backing on to our garden. The fence is partially down but we don't encroach on the path that runs along their north wall. In face before I was here full time the house which gad been for sale for ages had been purchased and improved by a Bulgarian woman and they had installed and internal bathroom with the waste pipe coming out of the north wall and into the ground on the path. So I'm assuming that as long as they can access the back of the house we or at the moment I don't need to renew the fence.
