My nephew took a car out of my yard and drove it to school one day without my knowledge/permission. (The car was uninsured and was sitting for repairs) . One his way home-he rear ended another vehicle causing some damage. The other guy got an estimate for repair but So far-he (my nephew) and his mother have not made an attempt to pay. He has called me and threatened to take me to court because I am the registered owner of the car. I would like to know if I am going to be held liable or if his parents will be. I live in Florida.
