My mom passed away. She has a car that is registered in her name, has a loan on it and is on her car insurance. She sold the car to a girl that she worked with and she pays my dad a payment every month since my mom passed however everything is in my mom's name. I have called this girl twice because she needs to get a loan to pay my dad off and then we can everything switched to her name. She does not return phone calls. There was a written agreement written that mom and this girl signed that if one or the other passed the living person became owner of the vehicle. However everything, the loan, the registration and the insurance are in my mom's name. Can we go take the vehicle back?
