Has anyone ever done an adverse possession claim and got any tips or idea how much it will cost to do through a solicitor? The garden behind our house has been fenced off and used solely by the owners of our house for the last 20 years at least. I have signed declarations (statement of truth) from the last two owners stating this covering up to 2005. The land is unregistered and we haven’t been able to find out who owns it. We have owned the house and used the garden for the last year. Thanks for any help and tips.
