You need to discuss your situation with a bk attny.
In a Chapter 7, obligations that arise out of a divorce decree are not dischargeable as provided by either 11 USC 523(a)(5) which is for domestic support obligations (DSO)or 11 USC 523(a)(15) which covers non DSO obligations.
In a Chapter 13 obligations that arise out of a divorce decree that "are not in the nature of support" under 523(a)(5), meaning they fall under 523(a)(15), are dischargeable. However, how your divorce decree reads is not necessarily how the bk court judge will interpret it. The bk judge has the independent right to determine if a particular obligation is "in the nature of support" and if he/she so determines, the obligation will not be dischargeable in a Chapter 13.
Go find a good bk attny.
