Yes. It is a misconception that credit card issuers do not have legal recourse for recovering money owed simply because the debt is considered "unsecured". Unsecured debt only signifies that there is no specific property attached to the debt itself. The debtor can be sued for the amount owe plus legal costs and other fees. If the plaintiff/creditor wins the suit (they always do) a judgment is enterered against the debtor/defendant. A judgment can be executed in accordance with the laws of the debtor's state, the preferred method of enforcing a creditor judgment is by wage garnishment or bank account levy. Other options are the seizure and sale of non exempt property belonging to the debtor and liens against real property belonging to the debtor.
