Secured creditor - A secured creditor is an individual or business that holds a claim against the debtor that is secured by a lien on property of the estate. The property subject to the lien is the secured creditor's collateral.⏎
Unsecured claim - A claim or debt for which a creditor holds no special assurance of payment, such as a mortgage or lien; a debt for which credit was extended based solely upon the creditor's assessment of the debtor's future ability to pay.⏎
Unscheduled debt - A debt that should have been listed by the debtor in the schedules filed with the court but was not. (Depending on the circumstances, an unscheduled debt may or may not be discharged.)⏎
Undersecured claim - A debt secured by property that is worth less than the amount of the debt.⏎
Trustee - The representative of the bankruptcy estate who exercises statutory powers, principally for the benefit of the unsecured creditors, under the general supervision of the court and the direct supervision of the U.S. trustee or bankruptcy administrator. The trustee is a private individual or corporation appointed in all chapter 7, chapter 12, and chapter 13 cases and some chapter 11 cases. The trustee's responsibilities include reviewing the debtor's petition and schedules and bringing actions against creditors or the debtor to recover property of the bankruptcy estate. In chapter 7, the trustee liquidates property of the estate, and makes distributions to creditors. Trustees in chapter 12 and 13 have similar duties to a chapter 7 trustee and the additional responsibilities of overseeing the debtor's plan, receiving payments from debtors, and disbursing plan payments to creditors.⏎
