In chapter 13 bankruptcy, only the chapter 13 debtor is allowed to file a chapter 13 plan. That is, creditors are not allowed to propose a plan as they are in chapter 11.
Chapter 13 plans generally are designed to adjust payment of debts under a flexible repayment plan. Usually these payments are made from future wages or income. There are some mandatory provisions for a chapter 13 plan, but most are permissive.
A chapter 13 plan is usually three to five years in length. Not all secured creditors - such as an up-to-date car loan - are required to be paid as part of the chapter 13 plan. Priority claims, such as child support and alimony arrearages, may be paid through the plan. Defaults in mortgage payments may be cured in a chapter 13 plan.
