California Code, Health and Safety Code - HSC § 103100

If any cemetery is located partly in one registration district and partly in another, only one permit shall be required for interment and a permit authorizing interment in the cemetery shall entitle interment to be made within or without the district to which the permit is directed. The permit shall be returned to the registration district in which the interment is made irrespective of the district to which it is directed. The local registrar of the district in which the interment is made shall forthwith file the permit on presentation without charge.
