Texas Family Code – FAM § 157.263. Confirmation of Arrearages
(a) If a motion for enforcement of child support requests a money judgment for arrearages, the court shall confirm the amount of arrearages and render one cumulative money judgment.
(b) A cumulative money judgment includes:
(1) unpaid child support not previously confirmed;
(2) the balance owed on previously confirmed arrearages or lump sum or retroactive support judgments;
(3) interest on the arrearages; and
(4) a statement that it is a cumulative judgment.
(b-1) In rendering a money judgment under this section, the court may not reduce or modify the amount of child support 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.
