I own an end of terrace house, there are just 3 houses in the block, i'm on the left, my mate is on the right and a middle aged Lady has the middle house. The Lady in the middle has access to her rear garden via a small alleyway accross the rear of my garden, i never took much notice of this when we moved in 10mths ago, but, looking at the Land Registry plans the alleyway is not mentioned or even drawn in! Looking at other blocks of 3 along the road, no other middle house has any rear access. So according to the plans can i claim back what i deem to be mine, ie; about a metre of rear garden?
