If I am selling my car at auction, do I need to sign the title?

A mechanic friend of mine is going to take my mustang and sell it at auction. Do I need to sign the title and give it to him for the auction?

Yes, you would need to sign the title so it can be transferred to the new buyer. You may also be required to provide a smog certificate and odometer reading, depending on the age of your vehicle. Once the vehicle has been sold you will need to fill out a form within 5 days on the California DMV website notifying them that you no longer own it.
