Depending on your case and situation, you might be able to discharge the debt that you owe the bank.Since I don't have all the facts of your specific case I'll go off the most common situation which is a "no asset" Chapter 7 consumer bankruptcy. Basically, if all of your assets (cars, bank accounts, home equity, etc.) are exempt, the trustee will probably file a report of no distribution meaning that none of your creditors will receive anything through the bankruptcy. So even though you didn't list the creditor on your petition they didn't miss out on anything. Technically you may be required to reopen the case to add them. But even if you did, they wouldn't receive anything despite the fact that they didn't have an opportunity to object because there wasn't anything being distributed to your creditors. A lot of people in this situation will have success just telling them that you discharged all your debt that you incurred before the filing date and give them a case number and/or notice of bk if you want.
