Hi - my name is XXXXX XXXXX I'm a Family Law litigation attorney here to assist you.
I would not advise that your son get involved with this at all. Because they weren't married, he is not responsible for the bills (generally would not be liable if they were married in non-community property states like Maryland). Thus, he has no liability, and I would be afraid that they would try to slip some paper to him that holds him responsible for the debts. Thus, it's better just not to get involved.
