10. NEW MEXICO-SPECIFIC NOTES

• Income Shares Model: New Mexico combines the parents' gross monthly income under § 40-4-11.1 and uses the current department support schedule and statutory worksheet.
• Two Worksheets: Worksheet A applies to basic visitation under 35%; Worksheet B applies only when each parent has at least 35% of the year and significantly shares parenting responsibilities and expenses.
• Imputation of Income: If the court finds willful unemployment or underemployment, it may impute earning potential after considering the statutory criteria. It may impute the prevailing local minimum wage for a parent without recent earnings history who can earn that wage; it may not impute income during incarceration of 180 days or longer.
• Excluded Income: General assistance, public assistance benefits received by the child, and child support received for other children are excluded from gross income.
• Proportional Additional Expenses: Health insurance and work-related childcare are divided proportionally by income share.
• Modification: Either party may seek modification upon a material and substantial change in circumstances.
