You, with or without the help of your lawyer, can start by investigating the judgment held by the lawyer - when and how it was obtained and why you were not served. From what you seem to be saying, your wife was the plaintiff in that lawsuit and obtained a judgment against you for support arrears, then assigned the judgment to her lawyers in satisfaction of some of her attorney fees. They are now claiming that the judgment is in the nature of child support and is nondischargeable. If that's the case, I think you'll find the following case (albeit not from your district) to be helpful - Simon, Schindler & Sandberg, LLP v. Gentilini (In re Gentilini), 365 B.R. 251, 255 (Bankr.S.D.Fla.2007). I think the reasoning is sound - the policy of nondischargeability of support obligations "has no application where, as here, discharge of the Fee Judgment will have no affect on the Former Spouse". (Note footnote 1, discussing the former language of the Bankruptcy Code, and the removal of the assignment provision from the current version.)
