How alimony works in New Mexico
New Mexico does not use a fixed statutory formula for alimony amounts. Judges weigh statutory factors — length of the marriage, each spouse's income and earning capacity, age and health, standard of living, and contributions to the marriage. Our calculator uses the AAML guideline formula (30% of payor's income minus 20% of recipient's) that attorneys commonly use for ballpark estimates.
Governing law: NMSA 1978 § 40-4-7 — Advisory non-binding committee guidelines suggest 30% of payor's gross minus 50% of payee's gross (28%/58% where child support is paid); courts retain full discretion.
