If you're behind on support payments, filing under Chapter 13 can legally stop your ex-spouse and support enforcement from pursuing you.
A support obligation is a very special kind of debt, and the resulting lien on your home has to be dealt with in a very special way.
You can't legally write off child support or spousal support.
The good news is that if you are behind on child or spousal support, with a resulting lien on your home, you can safely protect that home.
Before deciding that you have to sell your home to pay your ex-spouse, find out your legal options. You may be pleasantly surprised.
Besides providing a unique and powerful way to catch up on support arrearage, Chapter 13 can discharge other debts from your divorce.
