Cal. Veh. Code § 6160
The Legislature finds and declares that when vehicles are exported and their title records are not amended to reflect exportation, it is conducive to vehicle theft and insurance fraud. The certificates of title issued by this state are used in insurance frauds in which a claimant falsely states that a vehicle has been stolen or uses that certificate to fraudulently procure insurance when in fact the vehicle has previously been exported from the United States. In the interest of the general welfare of the people of this state, and in order to combat vehicle theft and insurance fraud, it is necessary that the department's record of title reflect the fact that a vehicle is being exported either temporarily or permanently, based upon the true owner's declaration prior to exportation.
