Hello, I am a solicitor with over 15 years experience. Ii will try to answer this.
I need more information you will need to tell me when the last person who gave you permission to use the land sold it?
Sorry I have misread that. The important thing is how long you have been using the land as if it were your own without permission from anyone. If this is only 5 years or so you will not have acquired any right to the land.
