Types of Alimony in New Mexico
New Mexico courts may award the following types of alimony:
- Transitional spousal support (supplements income for a limited
- clearly stated period to help transition to self-sufficiency); Rehabilitative spousal support (provides education
- training
- or work experience to increase earning ability and become self-supporting); Indefinite/Permanent spousal support (no set end date
- continues until death of either party
- remarriage of recipient
- or substantial change in circumstances); Lump-sum spousal support (single sum paid in one or more installments with specified definite amounts). Courts routinely favor rehabilitative support over other forms.
How New Mexico Calculates Alimony
New Mexico does not have a fixed formula for calculating alimony. Courts use judicial discretion, weighing multiple factors to determine a fair amount and duration.
New Mexico courts consider these factors when determining alimony:
- Under NMSA § 40-4-7
- courts consider these factors: (1) ages of the spouses; (2) health of the spouses; (3) current and future earnings and earning capacity of each spouse; (4) good-faith efforts of each spouse to maintain employment or become self-supporting; (5) reasonable needs of each spouse
- including the standard of living during the marriage; (6) duration of the marriage; (7) amount of property awarded to each spouse; (8) income available to either spouse through investments or other assets; (9) each spouse’s assets
- debts
- and financial resources; (10) the needs of any minor children of the marriage; and any other factors the court deems just and equitable.
Income disparity: YES. New Mexico requires a showing that one spouse has a financial need for support and the other spouse has the ability to pay. The requesting spouse must demonstrate an inability to meet reasonable needs independently while the other spouse has sufficient income or resources to provide support.
Vocational evaluation: YES. New Mexico courts may order or consider vocational evaluations to assess a spouse’s realistic earning capacity, particularly when a spouse lacks recent work history or specialized skills. Courts focus on what someone can earn (earning capacity), not just current income, and vocational evaluations provide a factual foundation for that determination. These evaluations are used to substantiate or challenge support estimates.
New Mexico Alimony Duration Guidelines
No statutory duration guidelines, but general judicial practice follows these patterns: marriages under 5 years typically receive no alimony (absent exceptional need); marriages of 5-10 years typically receive only rehabilitative or transitional alimony; marriages of 10-20 years typically receive support for 30% to 50% of the years of marriage (e.g., a 10-year marriage = 3-5 years of support); marriages over 20 years are candidates for indefinite/permanent support. Marriages lasting 20+ years trigger permanent court jurisdiction over spousal support, meaning the court retains authority to modify or extend payments indefinitely.
| Marriage Length | Typical Alimony Duration |
|---|---|
| Short-term (under Under 5 years (general judicial practice, not statutory; alimony typically not awarded absent exceptional circumstances)) | Rehabilitative or bridge-the-gap; limited duration |
| Moderate-term | Durational alimony; set period based on marriage length |
| Long-term (20 years (marriages of 20+ years are candidates for indefinite/permanent alimony and trigger permanent court jurisdiction over spousal support)+) | May qualify for permanent or indefinite alimony |
Permanent alimony: YES. New Mexico allows indefinite/permanent spousal support, particularly for long-term marriages of 20+ years. Permanent support has no set end date and continues until death of either party, remarriage of the recipient, or a court-ordered modification based on substantial change in circumstances.
Modifying & Terminating New Mexico Alimony
Modification: YES. Either party may petition the court to modify or terminate spousal support upon showing a material and substantial change in circumstances. Examples include: significant change in either party’s income, recipient’s remarriage, recipient’s cohabitation with a new partner, serious illness or disability, or payor’s retirement. The motion must be filed with the district court that issued the original divorce decree. Modification hearings typically occur within 60-90 days of filing.

Cohabitation: Cohabitation with a new romantic partner can justify reducing or terminating alimony when the living arrangement substantially reduces the recipient’s financial need. The paying spouse must prove both the cohabitation and its financial impact. Courts examine whether the relationship resembles a marriage with shared finances, not merely romantic dating. Cohabitation does not automatically terminate alimony; the payor must file a motion and demonstrate the financial impact.
Remarriage: Remarriage of the recipient spouse terminates alimony in New Mexico unless the divorce decree specifically provides otherwise. However, the paying spouse should still file a formal motion to modify/terminate rather than simply stopping payments, as stopping without a court order risks contempt charges.
Retirement: Retirement of the payor spouse constitutes a potential change in circumstances that may warrant modification or termination of spousal support. A planned or forthcoming retirement should be factored into any alimony calculation as it will materially affect the future financial circumstances of the parties. The payor must petition the court for modification; retirement does not automatically reduce or terminate alimony.
Tax Implications of New Mexico Alimony
Under the Tax Cuts and Jobs Act (2017), for divorce agreements executed after December 31, 2018, alimony payments are not deductible by the paying spouse and not taxable income for the receiving spouse at the federal level. This applies to all New Mexico divorces finalized after that date.
For divorces finalized before 2019, the old rules still apply unless the agreement is modified to adopt the new tax treatment.
Impact of Misconduct on New Mexico Alimony
Adultery: Adultery does NOT affect alimony awards in New Mexico. New Mexico courts have explicitly held that alimony decisions are independent of either spouse’s fault or guilt in the dissolution of the marriage. A spouse who committed adultery may still receive alimony if financial need is demonstrated, and a faithful spouse may still be ordered to pay if they have the ability to do so. Courts have consistently ruled since 1919 that marital misconduct, including infidelity, cannot be used to financially punish a cheating spouse.
Other marital misconduct: NO. Marital misconduct of any kind (including adultery, abuse, or other fault-based grounds) is NOT a factor in New Mexico alimony determinations. New Mexico is a no-fault divorce state, and the ten statutory factors under NMSA § 40-4-7 do not include fault or misconduct. Alimony is determined solely based on financial need and ability to pay.
Additional New Mexico rules: New Mexico is a community property state (NMSA § 40-3-8) — all property acquired during marriage is presumed community property and divided equally (50/50), which affects the property division factor in alimony determinations. The court may award spousal support from either community property or a spouse’s separate property. The unofficial Bernalillo County alimony guidelines, while not binding, are widely referenced by attorneys and mediators statewide as a starting point for negotiations. New Mexico courts have permanent jurisdiction over spousal support in marriages lasting 20+ years. Courts routinely favor rehabilitative spousal support to encourage self-sufficiency.
