A Chapter 13 proceeding, often called a wage-earner plan, is initiated by filing a petition. As in Chapter 7 cases, the filing of the petition automatically stays (stops) creditors from trying to collect on most of their debts. 11 USC §362. There is also a special automatic stay provision in Chapter 13 that protects co-debtors. A creditor generally may not seek to collect “consumer debts” from any individual who is liable along with the debtor. 11 USC §1301(a).
