Texas Family Code - FAM § 157.263. Confirmation of Arrearages

(a) If a motion requests a money judgment for child support, medical support, or dental support arrearages, the court shall confirm the amount of arrearages and render cumulative money judgments as follows:

(b) A cumulative money judgment for the amount of child support owed includes:

(b-1) A cumulative money judgment for the amount of medical support owed includes:

(b-2) A cumulative money judgment for the amount of dental support owed includes:

(b-3) In rendering a money judgment under this title that includes child support, medical support, or dental support arrearages, the court may not reduce or modify the amount of arrearages but, in confirming the amount of arrearages, may allow a counterclaim or offset as provided by this title.

(c) If the amount of arrearages confirmed by the court reflects a credit to the obligor for support arrearages collected from a federal tax refund under 42 U.S.C. Section 664, and, subsequently, the amount of that credit is reduced because the refund was adjusted because of an injured spouse claim by a jointly filing spouse, the tax return was amended, the return was audited by the Internal Revenue Service, or for another reason permitted by law, the court shall render a new cumulative judgment to include as arrearages an amount equal to the amount by which the credit was reduced.
