I shared a gate with my neighbour in our terrace to access our car parking area. Each of the houses in the terrace of four owns a car parking spaces adjacent to our gardens. My use of the gate shared by me and my immediate neighbour meant me crossing 30cms of that neighbour's garden. This arrangement has existed for about 17 years when the current garden/parking area configuration was created by an adjoining development being built. When I bought my property 13 years back my solicitor did flag up that no RoW was currently on my title (titles only registered in 2002 as individual plots in the terrace) but I was in a hurry to complete so didn't address this then (dumb, never do this!). My neighbour has now built a fence that does not include a gate so I can no longer access my parking space without a 5 min detour along a public road. I have tried to resolve this with the neighbour as i believe if we can reach an agreement (she currently uses a bit of my land to access her car parking space) we can just register with the Land Reg. The previous owner of my property used the shared gate which means that it has been used for over 20 years but not by the same occupants. Can that combined usage constitute an easement? Any advice please?
