It depends the state you are in. Contact your local dmv and ask them.. but if your trying to sell the car behind some-1s back they can bring u into court and make you pay fo’ the price of the car. So your better off waiting fo’ them to sign the title over too.
It depends on what is between the two names. “And” both must sign. “Or” either may sign.
