My question involves vehicle registration or title in the state of: Florida

Hello, my sister's ex has a suspended license, he helped her co-sign the loan for her minivan, he's in jail now for DUI and has his license suspended for 4 years. She's makes the payments on the minivan and has been trying to find a way to get him out of the title so she can renew the registration, because of the age of the van a mileage shes not able to refinance it or sell it, her registration expired 12/04 and she's pretty much stuck with no car, no way to get to work or take my niece and nephew to day care... we would be very grateful with you guys if you could provide us with some ideas to get her out of that mess.

thanks so much in advance.
