Wondergirl, I'm not talking about forgiven debt but charged off debt. When the creditor takes a tax loss. I frequently warn people that they still have the obligation to pay their debts. But sometimes circumstances do prevent it. The situation with the OP is an example. When his mom was using that Sears card, I'm sure she didn't expect to become disabled and not be able to pay her debts.
Many debt collectors use less than ethical means to harass and badger people to pay such debts. They do so without any consideration for the circumstances of the debtor.
