Debts incurred by reason of fraud are not dischargeable in bankruptcy. That's not state-specific, but is something true in every state. Based upon the facts you have given, and qualifying my assessment by stating that there are two sides to every story and I have only one side, I think your boyfriend's lawyer should have tried to bring the fraud case into the bankruptcy and to litigate it in the bankruptcy court or, in the alternative, made clear to your boyfriend that he needed to defend against the fraud case if he wanted to avoid a potentially non-dischargeable debt along with the exaggerated judgment that very often follows a default.

Your boyfriend needs to get help to try to get the default set aside, and shouldn't dawdle - time is not on his side, and the longer he waits the less likely it becomes that he'll succeed. He should also consider consulting a legal malpractice attorney.
