511 – Adverse Possession Under Written Instrument or Judgment.

§  511. Adverse possession under written instrument or judgment. Where
  the occupant or those under whom the occupant claims  entered  into  the
  possession  of the premises under claim of right, exclusive of any other
  right, founding  the  claim  upon  a  written  instrument,  as  being  a
  conveyance  of  the premises in question, or upon the decree or judgment
  of a competent court, and there has  been  a  continued  occupation  and
  possession  of  the  premises  included  in  the  instrument,  decree or
  judgment, or of some part thereof, for ten years, under the same  claim,
  the  premises so included are deemed to have been held adversely; except
  that when they consist of a tract divided into lots, the  possession  of
  one lot is not deemed a possession of any other lot.
