In bankruptcy cases, the Debtor is the individual or business who has claimed bankruptcy. The Creditor is the individual or business that was owed money from the debtor. Once a case is over, if the unclaimed money is due to the debtor (All debts were paid and there is an over-payment, undelivered check, etc), their name is put into the Creditor column to show they are the ones owed this left-over money.
