Dear Erika, my ex filed for bankruptcy and he owes a huge amount of back child support. Will he be able to wipe out that debt?

No, just no.  In bankruptcy, child support is a special category of debt and is NOT dischargeable.  In fact, unlike most other debts,  you can continue to pursue payment of child support while the bankruptcy case is pending. This doesn't mean you should ignore the fact that an ex-spouse or partner has filed for bankruptcy. In cases in which the debtor has assets that trustee is going to liquidate (sell), you want to make sure the trustee administering the case knows about the debt, knows the amount of the debt, and who needs to be paid.  Child support is a priority do in bankruptcy case.  This means it should be paid before many other debts.  However, the trustee can't pay a debt he doesn't know about.
