§ 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.
