both of our names are on the title but i have the title and signed contract stating that she is suppose to pay me for the car ! but she took the car and traded it in to a dealer and the dealer requested a new title from the dv
Yeah, this is a problem when you co-own property and it leaves your possession. Lots of people show up at a dealers lot wanting to sell or trade in a vehicle, and the dealers have right to process the transaction without the title. You probably can't get the vehicle back, but you may have grounds to sue the ex girlfriend. Hope this perspective helps!
