We live in an upstairs maisonette. Our garden is accessed through a shared use path. A small part of it is paved and has a (low) fence around it. This area is used to store wheelie bins and recycling boxes and bags, by us and our downstairs neighbour. This arrangement was already in place when we bought the house last year. We now want to put up a fence along the path, to give us more privacy and improve security. Seeing as the bin storage area is technically part of our garden, we want to remove the fences around it and incorporate the area (this would also make it easier to build the fence as there would be fewer corners). Can we just inform our neighbour of our plans (and that she'll have to keep her bins elsewhere) and crack on, or does the fact that the bin storage area has been there for a while mean that she can now claim she has a right to use it? We don't get on with her at all so I want to make sure I know exactly where I stand before I speak to her. I know I shouldn't take legal advice from randoms on the internet, so it would be great if you could tell me the terminology and area of law I need to look into and then I can do my own research😊
