Adverse Possession and the State
http://www.appeal-democrat.com/news/property-122093-land-owners.html
The notion that simply because one uses land which is State owned for a long enough time will create adverse possession is not necessarily true. Each State has its own statutes and Court decision, frequently finding that the State is the owner even though it exercises no possessory right to property. For years it would be otherwise barred by the adverse possession statute. Each State follows its own process, so one must closely view how adverse possession against the governmental agency is treated in the owner’s respective State.
