Legal Question in Civil Litigation in California

First tell them that you understand to some extent their anger, but it is illegal harassment of your friends and family to bother them with the debt problem and they are opening themselves to a law suit or complaint to the police by doing so. They should deal directly with you and not involve others.

It soumds as though the GF was the legal buyer of the car but let you keep it until you could not pay for it. When they sold the car without asking you they were indicting that you were not the legal owner [car could not be sold without legal owner's signature]. If that is the situation, then she had the primary obligation to pay for the car.

If the parents gave her the money which she then used to pay for the monthly payments missed while you had the car, then the loan was to her and not you as to the parents and they have no right to sue you. The exGF would be the only one who could sue you, and that depends upon whaa your agreement was with her as to who would make the payments. When she sold the car, if you were equal owners, she should either have divided the proceeds by the same ratio of what each of you paid on the car or subtracted each of your payments and divided the rest by that ratio, or whatever other agreement you had.

If they wil not stop, perhaps the only thing you can do is complain to the police after trying to get your exGF to try to get them to stop asnd then suing in Small Claims court for a portion of the car sales price and emotional and let the judge rule you were not the owner and just entitled to a little money for their harassing you for something yo do not owe.
