If there is a deficiency in the sale proceeds against the remaining value of the loan then the bank or finance company can sue your son as a co-signer, since he is jointly responsible for the loan. He also can sue the ex-girlfriend if he knows where she can be served. Optimally, he may be able to settle with the creditor for less than the full value, but it would be better to do that before than after any lawsuit because then attorney fees and court costs get added in. Contact an attorney.
