If you have a particular credit card that you want to use after filing bankruptcy, you could file what is called a reaffirmation agreement. This is an agreement to repay the debt owed to the particular creditor rather than have it discharged. With a reaffirmation agreement, credit card companies are likely to permit you to use the card after bankruptcy, though it is left to the discretion of the credit card company. It is recommended that you speak with a bankruptcy lawyer before signing a reaffirmation agreement.
