Article 5 - (501 - 551) ADVERSE POSSESSION
531 - Adverse possession, how affected by relation of landlord and tenant.

 
    §  531.  Adverse  possession, how affected by relation of landlord and
  tenant. Where the relation of  landlord  and  tenant  has  existed,  the
  possession  of the tenant is deemed the possession of the landlord until
  the expiration of ten years after the termination of  the  tenancy;  or,
  where there has been no written lease, until the expiration of ten years
  after  the  last  payment  of  rent; notwithstanding that the tenant has
  acquired another title or has claimed to hold adversely to his landlord.
  But this presumption shall cease after the periods  prescribed  in  this
  section  and  such  tenant  may  then  commence to hold adversely to his
  landlord.
