A bit of background: During the bankruptcy process, you must list all of your assets (property) and all of your debts (money that you owe). Once your creditors receive notice of your bankruptcy, every credit card on which you owe money will be deactivated and cancelled. However, if you have no balance on a credit card at the time of filing, then there is no debt on it and would not need to be listed, and sometimes, the credit card company will allow the account to remain open through the entire bankruptcy process. Other times, though, even accounts with no balances will be closed upon filing for bankruptcy.
