New Mexico Legal Separation Agreement

Q: Does New Mexico offer legal separation?

Not by that name. New Mexico does not enter a decree called legal separation. It provides a Section 40-4-3 proceeding for spouses who have permanently separated, letting the court divide property and set support and custody without a divorce, and it recognizes private separation agreements. Both keep the marriage in place and neither spouse may remarry. To end the marriage, a spouse files for a divorce, which is a separate step.

Q: What is a Section 40-4-3 proceeding in New Mexico?

It is New Mexico's court track for a couple that has permanently separated. Under NMSA 1978, Section 40-4-3, where a husband and wife have permanent and irreconcilable differences and have permanently separated and no longer live or cohabit together, either may institute proceedings for a division of property, disposition of children, or alimony, without asking for or obtaining a dissolution of marriage. The marriage remains in place throughout the proceeding.

Q: Does a New Mexico separation change marital status?

No. A New Mexico Section 40-4-3 proceeding fixes property, support, and custody but does not dissolve the marriage. New Mexico law states that a decree of separation that does not terminate the status of husband and wife is not a divorce (NMSA 1978, Section 45-2-802). So after the proceeding the spouses are still legally married and neither may remarry until a divorce ends the marriage.

Q: How is separation in New Mexico different from a divorce?

A New Mexico divorce ends the marriage, so both people are single again and free to remarry. A Section 40-4-3 separation keeps the marriage in place: the court can divide property and set support and custody, but the spouses stay married and neither may remarry (NMSA 1978, Sections 40-4-3, 45-2-802). The main difference is marital status, which only a divorce changes.

Q: Can a New Mexico separation be converted into a divorce?

There is no automatic conversion, because a Section 40-4-3 proceeding is not a status decree. To end the marriage a spouse files for a divorce, which requires six months of residence in New Mexico (NMSA 1978, Section 40-4-5). If one spouse seeks a divorce, the court can proceed with a dissolution even if the other wants only a separation, so a separated couple can move to a divorce by filing for one.

Q: Why choose separation instead of divorce in New Mexico?

People stay married and separate for practical or personal reasons. Staying married can keep one spouse on the other's health insurance, though many plans treat a separation the same as a divorce, so confirm with the insurer. Reaching ten years of marriage can matter for certain military and Social Security spousal benefits. Some couples separate rather than divorce for religious reasons, and others use it as a step short of ending the marriage, keeping the option to file for a divorce later.

New Mexico does not use the term legal separation; NMSA 40-4-3 lets permanently separated spouses divide property and set support without a divorce. Attorney review available.

Introduction

New Mexico does not use the term legal separation in its statutes, but it provides a close equivalent: when a husband and wife have permanent and irreconcilable differences and have permanently separated and no longer live together as a married couple, either spouse may ask the district court for a division of property, disposition of children, or alimony without asking for or obtaining a dissolution of marriage (NMSA 1978, Section 40-4-3). This lets a couple settle their affairs through the court while staying legally married, so neither spouse may remarry. The proceeding does not change marital status: New Mexico law provides that a decree of separation that does not terminate the status of husband and wife is not a divorce (NMSA 1978, Section 45-2-802), which is why the couple remains married after it. To use the Section 40-4-3 track the spouses must have permanently separated and no longer live or cohabit together as husband and wife. Couples choose this over a divorce to keep a spouse on health insurance, to reach the ten-year mark for certain military and Social Security spousal benefits, for religious reasons, or as a step short of ending the marriage. To end the marriage a spouse files for a divorce, which requires six months of residence in the state (NMSA 1978, Section 40-4-5); if one spouse seeks a divorce, the court can proceed with a dissolution even if the other wants only a separation. New Mexico is a community-property state, so property acquired during the marriage is generally shared equally; because those division terms are the same ones used to end a marriage, they belong in a New Mexico Marital Settlement Agreement, and if you decide to end the marriage the pleading that starts it is a New Mexico Divorce Petition. DocDraft builds your New Mexico separation agreement from your facts, with attorney review available before you sign.

SEPARATION AGREEMENT (NEW MEXICO)

(New Mexico does not enter a decree of legal separation. This is a private separation agreement; permanently separated spouses may also bring a proceeding under NMSA 1978, Section 40-4-3.)

District Court, County of [COUNTY], State of New Mexico (if a Section 40-4-3 proceeding is filed) In the Matter of: [SPOUSE 1 FULL NAME] and [SPOUSE 2 FULL NAME] No. [CASE NUMBER, if any]

This Separation Agreement is made between [SPOUSE 1 NAME] and [SPOUSE 2 NAME], who were married on [MARRIAGE DATE] and separated on [DATE OF SEPARATION].

Status and intent. The parties have permanent and irreconcilable differences, have permanently separated, and no longer live or cohabit together as husband and wife. They intend to stay legally married while living apart, and they understand that New Mexico does not enter a decree of legal separation that changes marital status, that neither may remarry, and that the marriage ends only through a divorce. The parties enter this agreement freely and voluntarily and have each disclosed their income, assets, and debts.

New Mexico framework. New Mexico offers two tools short of divorce. First, this private separation agreement, settling the parties' property, debts, support, and parenting while the marriage remains in place. Second, a proceeding under NMSA 1978, Section 40-4-3: where a husband and wife have permanent and irreconcilable differences and have permanently separated and no longer live or cohabit together, either may institute proceedings in the district court for a division of property, disposition of children, or alimony, without asking for or obtaining a dissolution of marriage. A decree of separation that does not terminate the status of husband and wife is not a divorce (NMSA 1978, Section 45-2-802).

Ending the marriage. This agreement does not end the marriage. To dissolve the marriage, a spouse must file for a divorce, which requires six months of residence in New Mexico (NMSA 1978, Section 40-4-5).

Alimony. The parties agree that [alimony of $[AMOUNT] per month shall be paid by ___ to ___ beginning [DATE] / neither party shall pay alimony], and that the court may order alimony in a Section 40-4-3 proceeding.

Property and debts. New Mexico is a community-property state, so property acquired during the marriage is generally shared equally. Because dividing property is the same work used to end a marriage, the parties set the division out in a New Mexico marital settlement agreement rather than repeat it here; see New Mexico Marital Settlement Agreement. The parties agree that: [SUMMARIZE OR ATTACH the division of community and separate property and debts].

Children and parenting. The parties have [NUMBER] minor child(ren): [NAME(S) AND DATE(S) OF BIRTH]. Custody, timesharing, and child support are [DESCRIBED HERE / set out in an attached parenting plan]. Custody and child support remain subject to court approval and modification in the best interests of the children.

Signatures. Each party signs freely.

[SPOUSE 1 SIGNATURE] Date: ______ [SPOUSE 2 SIGNATURE] Date: ______

New Mexico Requirements for Legal Separation Agreement

No Legal Separation by That Name
New Mexico does not use the term legal separation in its statutes and enters no legal-separation decree. The close equivalent is a Section 40-4-3 proceeding, and a couple may also sign a private separation agreement. The couple stays legally married.
Section 40-4-3 Proceeding
Under NMSA 1978, Section 40-4-3, permanently separated spouses may institute proceedings in the district court for a division of property, disposition of children, or alimony, without asking for or obtaining a dissolution of marriage.
Permanent Separation Required
To use the Section 40-4-3 track, the spouses must have permanent and irreconcilable differences and have permanently separated and no longer live or cohabit together as husband and wife.
Marriage Not Dissolved
A Section 40-4-3 proceeding and a private separation agreement do not end the marriage. A decree of separation that does not terminate the status of husband and wife is not a divorce (NMSA 1978, Section 45-2-802), so neither spouse may remarry.
Ending the Marriage Requires a Divorce
To end the marriage a spouse must file for a divorce, which requires six months of residence in New Mexico (NMSA 1978, Section 40-4-5). If one spouse seeks a divorce, the court can proceed with a dissolution even if the other wants only a separation.
Community Property
New Mexico is a community-property state, so property acquired during the marriage is generally shared equally. Because this is the same division used to end a marriage, set it out in a New Mexico marital settlement agreement rather than in the separation itself.
Private Separation Agreement
A New Mexico private separation agreement is a contract in which the spouses settle property, debts, support, and parenting while staying married. It fixes rights between the spouses but does not change marital status.
Reasons to Stay Married Rather Than Divorce
Couples stay married and separate to preserve a spouse's health insurance, to reach the ten-year mark for certain military and Social Security benefits, or for religious or step-short-of-divorce reasons. Confirm insurance effects with the plan, since many treat a separation like a divorce.
