i'm pretty sure you own your side of HER fence because it faces your property you are required to maintain it ....... anyone else heard of this??? not sure if you find this interesting but my elderly neighbor was sold an 8ft 8 inches high!!!! green metal security fence to replace his existing 3ft wooden fence. salesman used heavy persuasion and scare tactics, crime going up, had many break ins round here? etc.. etc.. and got £3000 plus for a 1 day job. my garden looks like a industrial estate now! Climar colourfence - avoid them like the plague. even if this was just a rogue salesman, the fence is higher than any planning permission could ever be granted for it, the 2 guys who put it up must have known that!
