40-4-11.2. Grounds for deviation from child support guidelines.
Any deviation from the child support guideline amounts set forth in Section 40-4-11.1 NMSA 1978 shall be supported by a written finding in the decree, judgment or order of child support that application of the guidelines would be unjust or inappropriate. Circumstances creating a substantial hardship in the obligor, obligee or subject children may justify a deviation upward or downward from the amount that would otherwise be payable under the guidelines.
