When is a Chapter 13 case preferable to a Chapter 7 case?

Chapter 13 is usually preferable for a person who has valuable nonexempt property or has valuable exempt property securing debts, either of which would be lost in a Chapter 7 case, is not eligible under means testing to maintain a Chapter 7 case, is not eligible for a Chapter 7 discharge, or has sufficient assets with which to repay most of his or her debts, but needs temporary relief from creditors in order to do so.
