That's how we came to own our half of the ransom strip retained by developer the between our property and our neighbour. No dispute, but they'll have to pay to get vehicular access from the planned retirement bungalow in a corner of their large garden, into our cul-de-sac. Our fee will be quite reasonable, starting at 5 figures....
Yeah, I was a bit worried about that but I checked the details and for her to claim adverse possession she'd have to make a formal claim with the land registry and they'd have to inform us and, unless there were some exceptional circumstances, any objection from the land owner would result in her claim being rejected.
I phoned the Citizens Advice Bureau and they told me that "the title deeds are the be all and end all" and she has no legal way to stop us putting the fence where we like as long as it doesn't cross the boundary. They suggested giving her some compensation to make things a little less acrimonious and also save on legal bills.
