Thanks for your question.
In order to claim the land you would have to apply to have it registered in your name at the Land Registry by proving what is called "adverse possession"
If the land in question is unregistered then you must have been using it continuously for 12 years in order to claim possession of it and be registered as the registered propreitor at the Land Registry If the land is registered then you need only have been using it continuously for 10 years in order to apply for adverse possession at the Land Registry. Notice of the application will be sent to the current registered proprietor of the land, who is obviously at liberty to object. It is therefore more difficult to claim adverse possession of land that is registered.If you do not know whether the land is registered then you can check using the Lan Registry's online service by downloading a copy of the register of the title (if any) for the property:-https://www.landregistry.gov.uk/wps/portal/Property_Search
In both cases, the application would be made to the Land Registry by using their Form ADV1 and the owner of the land has the right to raise objections to your applications.
