Wayleaves are well understood and are as stated in the link given by Harley. However, cat's situation is not a wayleave. A stay has somehow become installed on their land. The Board have not asserted a right to the land, have volunteered that it can be moved and have asked for the trivial sum of �290. It is the bargain of a lifetime. The Board could quite easily claim adverse possession and leave cat to start the legals, which will cost not less than I have said with outcome uncertain. If cat does nothing or upsets the Board, one day they will claim the land, which will be not less than 200mm each side of the wire and not less than 200mm beyond the furthest point of the anchor. The wisest course of action is to phone the Board and get a date for the work against their offer, and then to accept including the date and pre-payment. That way cat will have turned the tables by having a contract by which cat can sue the Board with certainty of success and no costs if the Board do not perform.
