Not too long ago my son backed out of the driveway of our house into a car that was parked on the street. This car was partially blocking the driveway in such a manner as he had to really maneuver the car to try and get out. The car he was driving was mine and there was no insurance on it at the time. There was no police report filed. The car that was damaged belonged to one of his sister's friends. I told her to get an estimate so that I could pay her for it. I didn't receive an estimate for the damages from her and she has since had the car repaired. My son is of legal age. Where does the responsibility fall for the repairs to the car? Does it fall on my son? Am I liable and can I be sued? I made a good faith effort to find out what the costs of the repairs would be.
