Do you need a pink slip to sell car in the state of California?

In the state of California, a pink slip is not required to sell a car. Instead, the seller must provide the buyer with a Certificate of Title, which is a legal document that proves ownership of the vehicle. The seller must also sign and date the title, and the buyer must sign and date it as well. In some cases, the buyer may also need to provide proof of insurance. Once the title has been transferred, the buyer can take the vehicle to the Department of Motor Vehicles (DMV) to register it in their name.
