When you file for bankruptcy, the creditors have a deadline to file a complaint objecting to the discharge of the debtor or to determine the dischargeability of certain debts. Are there exemptions to the deadline? Specifically, if a creditor were to argue the dischargeability of a certain debt based on the precedent of another bankruptcy case, can they still make that argument after the filing deadline has passed?
No. The only exception would be if they don't have notice of the bankruptcy filing.
What daniel says is correct.
