The dedication document shall specify the length of time for which the dedication is made. Dedicated property shall be held and used exclusively for pet cemetery purposes, unless and until the dedication is removed from all or any part of the property by an order and decree of the superior court of the county in which the property is situated, in a proceeding brought by the pet cemetery owners for the purpose of removing the pet cemetery dedication and upon notice of hearing and proof satisfactory to the court of both of the following: (a) That no interments were made in, or that all interments have been removed from, that portion of the property from which the dedication is sought to be removed. (b) That the pet cemetery owners have received written authorization from those persons whose pets have been buried in the cemetery, or their heirs or assignees, to remove the dedication from their respective plots or to disinter the pet for removal to another plot location. The written authorization may or may not be given for legal consideration.
