Property Division
New Mexico is a community property state. This means all assets and debts acquired during the marriage are presumed to belong equally to both spouses and are typically split 50/50. Separate property — assets owned before marriage or received as gifts/inheritance — remains with the owning spouse.
The median uncontested divorce in New Mexico costs approximately $7,500. Contested cases with significant property disputes average $30,000.
Child Custody
New Mexico courts determine custody based on the best interest of the child standard. Courts consider the child’s relationship with each parent, each parent’s ability to provide a stable environment, the child’s adjustment to home and school, and any history of domestic violence or substance abuse.
New Mexico uses the Income Shares model. Both parents' incomes are combined, and a state guideline table determines the total support obligation. Each parent's share is proportional to their percentage of the combined income.
Alimony & Spousal Support
Spousal support in New Mexico is determined by considering the length of the marriage, each spouse’s income and earning capacity, the standard of living established during the marriage, and each spouse’s contributions (including homemaking). Courts may award temporary, rehabilitative, durational, or permanent alimony depending on the circumstances.
Under NMSA §40-4-1, the court has broad discretion in setting the amount and duration of spousal support. Longer marriages (typically 15+ years) are more likely to result in longer-term or permanent alimony awards.
