A. A court may modify a child support obligation upon a showing of material and substantial changes in circumstances subsequent to the adjudication of the pre-existing order. There shall be a presumption of material and substantial changes in circumstances if application of the child support guidelines in Section 40-4-11.1 NMSA 1978 would result in a deviation upward or downward of more than twenty percent of the existing child support obligation and the petition for modification is filed more than one year after the filing of the pre-existing order.

B. All child support orders shall contain a provision for the annual exchange of financial information by the obligor and obligee upon a written request by either party. The financial information to be furnished shall include:

(1) federal and state tax returns, including all schedules, for the year preceding the request;

(2) W-2 statements for the year preceding the request;

(3) Internal Revenue Service Form 1099s for the year preceding the request;

(4) work-related daycare statements for the year preceding the request;

(5) dependent medical insurance premiums for the year preceding the request; and

(6) wage and payroll statements for four months preceding the request.

For the purposes of this subsection, the wages of a subsequent spouse may be omitted from the financial information provided by either the obligor or the obligee.

History: Laws 1990, ch. 58, § 1; 1991, ch. 206, § 2.

The 1991 amendment, effective June 14, 1991, rewrote this section to the extent that a detailed comparison would be impracticable.

Cases in which there is a presumption of material and substantial changes in circumstances. — In cases in which application of the parties' updated financial information to the child support guidelines results in a deviation upward or downward of more than twenty percent of the existing child support obligation, the party seeking modification is entitled to a rebuttable presumption of material and substantial changes in circumstances justifying a modification. Jury v. Jury, 2017-NMCA-036.

Where petitioner appealed the district court's denial of her motion to modify a 2010 child support decree, claiming that the district court's ruling resulted from its erroneous determination of the parties' gross monthly incomes and, by extension, child support obligations, reversal and remand for recalculation of the parties' gross monthly incomes was necessary to the extent that the district court improperly deviated from the child support guidelines in calculating the parties' gross monthly incomes and failed to specify the reasons for its decision in deviating from the child support guidelines, because the miscalculation potentially deprived petitioner of the presumption of material and substantial changes in circumstances. Jury v. Jury, 2017-NMCA-036.

Reduction of child support payments upon child reaching majority age. — When a prior decree directs that a noncustodial parent make lump-sum, periodic child support payments for two or more children, and one of the children subsequently reaches the age of majority, the best procedure for a noncustodial parent who seeks a reduction in child support is to obtain a stipulated order authorizing such modification, or alternatively to request a hearing on the request for reduction. McCurry v. McCurry, 1994-NMCA-047, 117 N.M. 564, 874 P.2d 25.
