The Chapter 13 plan must include provision for repayment of certain debts in full. These debts are called "priority debts." Priority debts include child support and alimony, wages you owe to employees, and certain tax obligations. The Chapter 13 plan must also include your regular payments on secured debts, such as a car loan or mortgage, as well as repayment of any secured debts that you have fallen behind on. While the Chapter 13 debtor could obtain a discharge on unsecured debts such as credit card payments, medical bills, judgments, etc, the plan must show that disposable income is going towards the repayment of unsecured debts. Unsecured debts may therefore be discharged if there isn't sufficient income to repay them.
