New Mexico Family Laws

New Mexico is a community property state with both no-fault and fault-based divorce grounds. The sole no-fault ground is "incompatibility." Residency requires at least 6 months of domicile. Community property is typically divided equally (50/50). New Mexico uses the income shares model for child support and considers the best interests of the child for custody. There is no statutory formula for spousal support (alimony) — courts have broad discretion. The Family Violence Protection Act provides orders of protection lasting up to 6 months, renewable.

Key New Mexico Statutes

Grounds for DissolutionN.M. Stat. Ann. § 40-4-1

New Mexico allows dissolution on four grounds: (A) incompatibility (no-fault), (B) cruel and inhuman treatment, (C) adultery, or (D) abandonment. Incompatibility exists when the marriage is pointless due to discord or conflict with no hope of reconciliation.

Community Property DivisionN.M. Stat. Ann. § 40-4-7

New Mexico is one of 9 community property states. Property acquired during marriage is presumed community property regardless of title. Community property is typically divided equally (50/50). Separate property (pre-marriage, gifts, inheritance) remains with the owning spouse.

Child Custody (Best Interest Standard)N.M. Stat. Ann. § 40-4-9

Custody is determined by the best interests of the child. Factors include the parent-child relationship, adjustment to home/school/community, mental and physical health of all individuals, and the child's wishes (if age 14+, the child may choose unless contrary to best interests). Domestic violence is a significant factor that can limit custody.

Joint CustodyN.M. Stat. Ann. § 40-4-9.1

Joint custody is presumed to be in the child's best interest. Parents must submit a parenting plan. The court considers domestic abuse history and which parent is more likely to foster a relationship with the other parent.

Child Support Guidelines (Income Shares)N.M. Stat. Ann. § 40-4-11.1

New Mexico uses the income shares model. Support is calculated based on the combined gross income of both parents, paid proportionally. Income includes actual gross income or potential income if unemployed/underemployed. Deviations allowed under N.M. Stat. Ann. § 40-4-11.2.

Spousal Support (Alimony)N.M. Stat. Ann. § 40-4-7

New Mexico has no formula for spousal support — courts have broad discretion. Factors include the duration of the marriage, age and health of each spouse, each spouse's earning capacity, and standard of living during the marriage. Generally, longer marriages (10+ years) are more likely to result in alimony awards.

Domestic Violence ProtectionN.M. Stat. Ann. §§ 40-13-1 through 40-13-10

The Family Violence Protection Act allows victims to petition for an order of protection. Orders last up to 6 months, renewable for an additional 6 months for good cause. Violation is a misdemeanor; second or subsequent violations carry a minimum 72 consecutive hours in jail.
