Four years ago I bought a used car from my ex. My mother wrote a check for the vehicle and I have had the vehicle in my possession ever since but have been unable to register the vehicle in my name. At the time I bought the vehicle she was my girlfriend and we lived together so I was not concerned with changing it in my name, which I now realize was a big mistake. We split up 2 years ago and have been trying to get her to sign it over. Last year she sued me for $2000 for random bills and I have been paying on it up until last month when I was laid off. I had a company vehicle to get me to and from work and now the only vehicle I have can't be registered and she says she wont sign the title over until she is paid in full. I have a canceled check that shows vehicle was paid and the statement from the credit card company showing the money was taken out for the car. Can I sue her for breach of contract and have her pay the fees for late registration for last 2 years? and how does the fact that i still owe her money for something else unrelated affect the case?
