Child Support in New Mexico
State-specific overview · Family Law
New Mexico uses income shares model; parents split child support based on combined income and custody time.
How New Mexico treats Child Support
New Mexico applies the income shares model under the Child Support Guidelines, meaning both parents contribute proportionally to their income levels. The state considers the percentage of time each parent spends with the child, adjusting support accordingly. Modifications occur when income changes by 10% or more, or when custody arrangements shift significantly. Child support typically continues until age 18, or 19 if the child remains in high school.
The general definition of Child Support
Court-ordered payments from one parent to the other for a child's living expenses.
Child support is money that a court requires one parent to pay to the other parent (or guardian) to help cover the child's expenses like food, housing, education, and healthcare. The amount is usually calculated using state guidelines that consider both parents' incomes, the number of children, and custody arrangements. Child support continues until the child reaches the age of majority, typically 18 or 21 depending on the state. It's a legal obligation separate from custody decisions.
