Factors That Affect Child Support in New Mexico
Technical details and legal basis
New Mexico uses the Income Shares model (NM Guidelines (NMSA 1978 § 40-4-11.1)) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
Important Notes for New Mexico
- • New Mexico uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
- • Each parent's share is proportional to their percentage of the combined gross income.
- • New Mexico allows adjustments for work-related child care, health insurance for the children, and extraordinary medical expenses.
- • The court may deviate from the guidelines when strict application would be unjust or inappropriate.
Example Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
