How to File for Divorce in New Mexico (2026)
Reviewed by DocDraft Legal Team · New Mexico · Last updated 2026-05-18
New Mexico runs its divorce process on its own family-law code. Asset division here is community property (assets acquired during the marriage are owned equally), and the no-fault ground is available without proving fault. The residency rule is its own: At the time of filing the petition, either party must have resided in New Mexico for at least six months immediately preceding the filing and must have a domicile in New Mexico (physical presence with present intention to reside permanently or indefinitely). This guide details what New Mexico requires from filing through final decree, with N.M. Stat. § 40-4-1 as the governing grounds statute.
Key Considerations
The asset question in a New Mexico divorce is governed by community-property. Community property: all property acquired during marriage by either spouse is presumed community property and is divided equally (50/50) upon dissolution. Separate property (acquired before marriage, by gift, or by inheritance) remains with the owning spouse. The controlling authority is N.M. Stat. § 40-3-8; § 40-4-7.
On spousal support, Court may award alimony as appropriate after considering enumerated factors at § 40-4-7(B)(2): age and health and means of support of respective spouses, current and future earnings and earning capacity, duration of marriage, amount of property owned, amount of separate property, support needs of children, length of cohabitation, treatment of the children of either spouse, and any other facts the court considers necessary. The governing authority is N.M. Stat. § 40-4-7(B)(2).
The child-support number is not discretionary: Income-shares model under N.M. Stat. § 40-4-11.1; both parents' combined gross income is applied to the Basic Child Support Schedule with adjustments for shared responsibility (when each parent has the child 35% or more of the time, joint physical custody worksheet B applies), health insurance, and child-care N.M. Stat. § 40-4-11.1 codifies it, with the official calculator via the state agency.

Relevant Laws
New Mexico Dissolution of Marriage - NMSA § 40-4-1
This statute establishes the legal grounds for divorce (called 'dissolution of marriage' in New Mexico). New Mexico is a no-fault divorce state, meaning you can file for divorce based on 'incompatibility' without proving wrongdoing. Understanding this law is essential as it forms the legal basis for ending your marriage.
New Mexico Community Property Laws - NMSA § 40-3-6 to 40-3-17
New Mexico is a community property state, meaning most property and debts acquired during marriage are considered equally owned by both spouses. These laws determine how your marital assets and debts will be divided in divorce. Property owned before marriage or received as gifts/inheritance typically remains separate property.
New Mexico Child Custody Laws - NMSA § 40-4-9
This statute governs child custody determinations in New Mexico. Courts make custody decisions based on the 'best interests of the child' standard. New Mexico courts generally favor joint custody arrangements when appropriate. If you have children, this law will determine how custody and parenting time are allocated.
New Mexico Child Support Guidelines - NMSA § 40-4-11.1
New Mexico uses specific guidelines to calculate child support based on both parents' incomes and the number of children. These guidelines determine financial support obligations for children after divorce. The court may deviate from these guidelines in certain circumstances if it finds the calculated amount would be unjust.
New Mexico Spousal Support (Alimony) - NMSA § 40-4-7
This law governs spousal support (alimony) in New Mexico. Courts consider factors such as duration of marriage, standard of living during marriage, age, health, and earning capacity when determining if alimony is appropriate. New Mexico allows for different types of alimony including transitional, rehabilitative, and indefinite support.
New Mexico Residency Requirements - NMSA § 40-4-5
To file for divorce in New Mexico, at least one spouse must have been a resident of the state for at least six months immediately preceding the filing. This residency requirement must be met before New Mexico courts have jurisdiction over your divorce case.
New Mexico Marital Settlement Agreements - NMSA § 40-4-7.1
This law allows spouses to create their own marital settlement agreement that addresses property division, debt allocation, spousal support, and child-related matters. If the court finds the agreement fair and not unconscionable, it will typically be incorporated into the final divorce decree. This can make your divorce more amicable and less costly.
