(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:
(1) a cumulative money judgment for the amount of child support owed under Subsection (b);
(2) a cumulative money judgment for the amount of medical support owed under Subsection (b-1); and
(3) a cumulative money judgment for the amount of dental support owed under Subsection (b-2).
(b) A cumulative money judgment for the amount of child support owed includes:
(1) unpaid child support not previously confirmed;
(2) the balance owed on previously confirmed child support arrearages or lump sum or retroactive child support judgments;
(3) interest on the child support arrearages; and
(4) a statement that it is a cumulative judgment for the amount of child support owed.

(b-1) A cumulative money judgment for the amount of medical support owed includes:
(1) unpaid medical support not previously confirmed;
(2) the balance owed on previously confirmed medical support arrearages or lump sum or retroactive medical support judgments;
(3) interest on the medical support arrearages; and
(4) a statement that it is a cumulative judgment for the amount of medical support owed.
(b-2) A cumulative money judgment for the amount of dental support owed includes:
(1) unpaid dental support not previously confirmed;
(2) the balance owed on previously confirmed dental support arrearages or lump sum or retroactive dental support judgments;
(3) interest on the dental support arrearages; and
(4) a statement that it is a cumulative judgment for the amount of dental support owed.
(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. § 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.
