Open ditches or drains between tenements are also considered as common if there be no title or sign proving the contrary.\nThere is a sign contrary to ownership in common when the earth or dirt removed to open or clean the ditch is only on one side thereof, in which case the ownership of the ditch shall be vested exclusively in the owner of the tenement having this exterior sign on its side.\nHistory —Civil Code, 1930, § 510.
