The California Certificate of Cancellation is a document issued by the California Department of Motor Vehicles (DMV) that officially terminates a vehicle's registration in the state. The Certificate of Cancellation is required to be presented when canceling vehicle registration in California. It is typically used when a vehicle has been sold, junked, or transported out of the state. There are two types of California Certificate of Cancellation: the Regular Certificate of Cancellation and the Enhanced Certificate of Cancellation. The Regular Certificate of Cancellation is used for vehicles that are no longer in use and are not being transferred to another state or another owner. The Enhanced Certificate of Cancellation is used for vehicles that are being sold, transferred, or exported out of the state. Both certificates are issued by the DMV and must be presented to complete the vehicle registration cancellation process.
