I have a very difficult problem that I'm trying to sort out. We had sold our house and the sale was progressing but then the buyer's solicitor came up with Land Registry document stating that we did not own a piece of land to the front of the house. This stopped the sale. I have been in touch with the National grid and UK Power Networks - both of which say they don't own the land. The land did have an Electrical substation on it but I don't have any paperwork stating when this was removed and by whom. Any help would be greatly appreciated. Thank you in advance.
