When you file for bankruptcy, you will be required to disclose your debts—which are also called creditor claims in bankruptcy court—and classify them as secured (home mortgage), unsecured (credit cards), priority unsecured (child support, alimony), or nonpriority unsecured (credit cards, medical bills).
Priority unsecured debts cannot be discharged in a Chapter 7 bankruptcy, and you will remain responsible for them after your Chapter 7 bankruptcy. Priority unsecured debts also cannot be discharged in a Chapter 13 bankruptcy, and must be paid in full in a three-to-five-year repayment plan.
