Sorry this is a long one. TLDR: Essentially we were gifted land from ex-neighbour when they died. New neighbours who bought her house has told us we must sell it to them.
A bit more backstorey. Our elderly neighbour lived next to us until they died in late December. She had a side bit of garden like an allotment that we used to help her with (hatched area on diagram). Unbeknownst to us she gifted us that area of land in her will. The rest of the house and land was to be sold and the money given to charity.
After the will reading we have had the land registry changed to confirm we now own the land. The house was put up for sale late January. In mid February we received a letter from a solicitor asking that we sell the land to the potential buyer of the house. We emailed back saying no we won't sell. We then heard nothing more from any solicitors. House was then sold during lockdown.
The new neighbours moved in on Monday. Yesterday they came to our door asking for the name of our solicitor so the land purchase can take place. We told them we were not planning on selling the land and that we told their solicitor that. The new neighbours didn't take it well. Apparently they only bought the house on the provision that they could buy the land and this was agreed with us via their solicitors.
The new neighbours got quite loud and angry about us apparently misleading them and left to speak to their solicitor. They seem to think we legally need to sell them the land as there was a written (email) contract between them and their solicitor who confirmed to them by email prior to the sale of the house that we would sell the land.
Aibu to a) not sell the land even though we technically didn't buy it and b) that the fact their solicitor has mislead them is not our problem?
Neighbours land is in red.
Our land is in black and the hatched area is the land they expect to buy.
