I don't think Chris thinks he'd have to pay off things that are entirely in Barb's name. So that's exempts the house and her credit cards. (Of course, then he'd need to find a new place to live.)That all depends on how much of Barbs debts hes on the hook for and how much of her debts he doesnt have to pay that he can be suckered into paying. I personally dont see him figuring out on his own what he has to pay and what he doesnt.
He's got his credit cards (upon which Barb offloaded some of her debt), which are around $6k, and most importantly, the car. Chris got a completely retarded loan for that car. He's going to be paying off like 3x the value of the car by the time he's done.
