When there are two or more owners of a cemetery space or right of interment, they may designate one or more persons, firms or corporations, trustees, or other entities to represent them and, upon filing written notice of designation with the cemetery authority, the cemetery authority in its discretion shall have the right to deal with such representative unless the cemetery authority receives written revocation of the designation executed by all of the co-owners or their heirs or legal representatives.
