No. its something to do with, if you build on a picec of land, and the bulding is clearly visiable, and no one objects or the counicl finds otu abotu it for 5 years or something, its all leagel and everything. there was a program on ITV about it i think, someone bulit this awfull house in teh cotsworlds, and hid it behind hay bails for a few years.
there is somthing about, if say you rented some land of the council, an then you stopped renting it, but it remaind at say, the bottom of your garden, and you kept using it even though you didnt rent it, and the council didnt say anything for 12 years, leagally it is yours. as long as you have been using it for 12 years and the councill have not noticed.
