People across Cumbria have been receiving letters from landowners laying claim to historic mineral rights under their homes.
Typically these claims are being made by successors to a Lord of the Manor title, which dates back to medieval times.
Descendants can still claim rights to hunt, shoot or fish and claim mineral rights on property that was once part of a manor.
However, due to a change in law, landowners now have to register these interests. The result is hundreds of homeowners are being surprised and shocked by the letters.
In this exclusive report, Hannah McNulty has been looking at what it all means.
