Facts

The case involves a dispute between divorced parents over a lump-sum child support payment of $2.5 million agreed upon in a Texas divorce decree. The father, who later gained custody of the child, sought credit for prepaid child support, arguing that the change in custody justified reimbursement or offset against other financial obligations owed to the mother. The mother opposed this claim, asserting that the lump-sum payment was final and non-modifiable (paras 2-7).

Procedural History

• Texas Divorce Decree, 1987: The decree awarded custody of the child to the mother and required the father to pay $2.5 million in lump-sum child support (para 2).
• Dona Ana County District Court, October 20, 1995: The court ruled that the father had fully paid the $2.5 million promissory note by January 1988 but required him to indemnify the mother for tax payments (para 4).
• Dona Ana County District Court, November 14, 1995: The court granted the father permanent custody of the child (para 5).

Parties' Submissions

• Appellant (Father): Argued that the $2.5 million lump-sum child support payment should be credited or offset due to the change in custody, as it resulted in an overpayment of child support. He sought to apply this credit against the indemnification owed to the mother for tax payments (paras 6, 11).
• Respondent (Mother): Contended that the lump-sum payment was final and non-modifiable under the Texas decree. She argued that the father’s motion was barred by res judicata and that the court lacked jurisdiction to retroactively modify child support obligations (paras 7, 9).

Legal Issues

• Whether the father is entitled to a credit or offset for prepaid lump-sum child support due to the change in custody of the child.
• Whether the Texas divorce decree’s lump-sum child support payment can be modified under New Mexico law (paras 10-11).

Disposition

• The Court of Appeals of New Mexico affirmed the district court’s dismissal of the father’s motion for credit or offset (para 24).

Reasons

Per Hartz CJ (Alarid and Apodaca JJ. concurring):

• The court held that the lump-sum child support payment in the Texas decree was final and non-modifiable. The decree did not provide for adjustments based on changes in custody or other circumstances, and the father failed to demonstrate exceptional circumstances justifying relief under Rule 1-060 NMRA (paras 12-14, 23).
• The court emphasized that New Mexico law prohibits retroactive modification of accrued child support obligations, and the lump-sum payment was fully satisfied and no longer subject to prospective application (paras 14-18).
• The father’s claim for relief under Rule 1-060(B)(5) was rejected because the judgment was not executory and did not require ongoing judicial supervision. Similarly, relief under Rule 1-060(B)(2) was unavailable because the change in custody was not newly discovered evidence but a foreseeable contingency (paras 16-19).
• The court found no exceptional circumstances under Rule 1-060(B)(6) to justify modifying the lump-sum award, noting that the father had agreed to the terms of the Texas decree and failed to anticipate potential changes in custody (paras 20-23).
