Cal. Veh. Code § 9864
The owner shall furnish the department notice of the wrecking or dismantling, or the destruction or abandonment of an undocumented vessel within 15 days thereof. The wrecking, dismantling, destruction or abandonment shall terminate the certificate of ownership and certificate of number of such undocumented vessel which if in existence shall be surrendered to the department.
The department, upon receiving notice of the abandonment of an undocumented vessel, or upon an official determination that an undocumented vessel has been abandoned, may order the destruction of such vessel at the expiration of 30 days if an investigation by the department has disclosed that no owner, legal owner, or lienholder claims an interest in the vessel, or if those persons have waived their interest. Nothing in this section shall be construed to deny the legal rights, otherwise provided for by law, of any person claiming an interest in an abandoned vessel if that person notifies the department within the time specified therefor.
