What is the name of your state (only U.S. law)? I live in Nevada, my question is what legal issue do I have if I have purchased a vehicle in my ex-girlfriend name due to a better interest rate and I have been making payments for about 5 years and I have registered and been paying the insurance from my account and now she wants to trade the vehicle in to use the equity for the down payment of her own vehicle. She is ultimately reposessing the vehicle without my consent is this legal?
