Leaving off a credit card because you want to continue to use the credit card is not a good idea and it won’t work anyway. Credit card companies and other creditors are constantly checking your credit reports in national databases and they will find out about the bankruptcy. They will cancel the card anyway, whether you owe a balance or not, no matter how good your payment record may have been.
Intentionally leaving a creditor off your bankruptcy papers may result in perjury or it may make the debt non-dischargeable and you will have to pay it. Let’s play it safe and list everyone. That way you are protected from them and you can always pay them later if you desire.
