50 of 100 on the Luck of the Draw Index

All states

Luck of the Draw score: 50 out of 100

New Mexico splits community property equally and leaves out marital fault, so the judge has little room on property. The judge has broad discretion over spousal support, and each side can excuse one assigned judge without giving a reason. On the book’s scale, 0 is a contract you can read and 100 is one that mostly says “ask the judge.” New Mexico ranks 5 of 51, counting from the state that leaves the least to the judge. How the index works, and every state’s score.

PartScoreThe rule, and where it comes from
Property0 / 20New Mexico divides community property equally at divorce, and the New Mexico Supreme Court describes this as a rule requiring equal division of the community.
Ruggles v. Ruggles, 116 N.M. 52, 860 P.2d 182 (1993)
Alimony20 / 20The court may award rehabilitative, transitional, indefinite or lump-sum spousal support and sets amount and duration by considering ten listed factors, with no statewide formula or durational limit.
NMSA 1978, § 40-4-7(B), (E)
Fault0 / 20Marital fault plays no role because community property must be divided equally and the spousal support statute directs the court to a closed list of ten factors that does not include fault or conduct.
NMSA 1978, § 40-4-7(E); Ruggles v. Ruggles, 116 N.M. 52 (1993); Beals ex rel. Walker v. Ares, 25 N.M. 459, 185 P. 780 (1919)
Lawyers’ fees20 / 20The court may order payment of the expenses of the proceeding so as to ensure either party an efficient preparation and presentation of that party’s case.
NMSA 1978, § 40-4-7(A)
Second opinion10 / 20Each party in a district court civil case may excuse one district judge without cause by filing a peremptory excusal within the rule’s deadlines, and no jury is available on property division or spousal support.
NMSA 1978, § 38-3-9; Rule 1-088.1 NMRA

Getting in

No waiting period. The couple must appear together before a county clerk with identification, and file the license in the issuing county after a ceremony in New Mexico. A district judge may excuse a person who cannot appear. The fee is $55. The statutes set no waiting period and no expiration date for the license.
N.M. Stat. Ann. §§ 40-1-10, 40-1-11 (as amended by Laws 2025, ch. 124)

Who can marry you. Ordained clergy, authorized representatives of federally recognized Indian nations, tribes and pueblos, and active or retired judges, justices and magistrates may officiate. A religious society or tribe may also solemnize a marriage under its own rites and certify it to the clerk. A ceremony needs witnesses; the statutory form has lines for two. The statute does not address online or mail-order ordination.
N.M. Stat. Ann. §§ 40-1-2, 40-1-3, 40-1-18

Common-law marriage: Not available here. A couple cannot form a common-law marriage in New Mexico; a marriage must be entered by contract and solemnized. The state does recognize a common-law marriage that was valid in the place where it was formed.
In re Estate of Bivians, 98 N.M. 722 (Ct. App. 1982); Medina v. Medina, 2006-NMCA-042, 139 N.M. 309; N.M. Stat. Ann. § 40-1-4

Chapter 5 of the book covers getting in, and whether you are in at all.

The property system

New Mexico is one of nine community property jurisdictions. Community property. What either of you earns during the marriage belongs to both of you as it’s earned, and it’s generally split in half at the end. Chapter 11 of the book covers what that means, and Chapter 22 covers what happens to it when you move.

What counts as marital. New Mexico is a community property state. What either spouse acquires during marriage is community; premarital property, gifts, inheritances, and property made separate by written agreement stay separate. Accumulation stops at a dissolution decree or a decree under the separation statute. Growth and income of separate property stay separate, but the community can claim growth caused by community funds or labor.
N.M. Stat. Ann. § 40-3-8; Portillo v. Shappie, 97 N.M. 59 (1981); Gabriele v. Gabriele, No. A-1-CA-34523 (N.M. Ct. App. Jan. 31, 2018)

An inheritance that touches a joint account

It depends on what the owner meant. Putting an inheritance into a joint account does not by itself make it community property; a spouse claiming that it changed must show the owner’s intent by clear and convincing evidence. But separate money so intermingled with community money that it cannot be traced is treated as community. The state supreme court kept inherited cash and bonds separate when placed in joint ownership for a limited purpose.
LeClert v. LeClert, 80 N.M. 235 (1969); Macias v. Macias, 1998-NMCA-170, 126 N.M. 303; Mitchell v. Mitchell, 1986-NMCA-028, 104 N.M. 205; Burlingham v. Burlingham, 72 N.M. 433 (1963)

Chapter 12 explains how mine becomes ours.

Your spouse’s medical bills (Article 5)

Both of you can be liable from the first dollar. New Mexico is a community property state: a debt either spouse incurs during marriage, including a medical bill, is a community debt unless it falls in a statutory separate-debt category, and it is paid first from all community property and then the residence; the other spouse’s separate property is not liable unless that spouse also incurred the debt.
NMSA 1978, §§ 40-3-9, 40-3-11

Chapter 8 of the book explains the three ways states handle this.

If one of you dies (Article 9)

New Mexico has no elective share. The surviving spouse already owns half of the community property; the decedent may will away only the decedent’s half, and without a will that half passes to the survivor. Quasi-community property is treated as community property only on divorce or legal separation, not at death.
NMSA 1978, §§ 45-2-102, 45-3-101, 40-3-8(D)

Chapter 9 covers what a will can and can’t take away from a spouse.

Prenups and postnups (Article 12)

One look, under UPAA (1983). A premarital agreement is unenforceable only if the challenger proves it was signed involuntarily, or was unconscionable when signed and the challenger lacked fair disclosure, did not waive disclosure in writing, and lacked adequate knowledge. Spouses may contract with each other about property, subject to the common-law rules for persons in a confidential relationship; outside property, they may contract only for an immediate separation and support during it.
NMSA 1978, §§ 40-3A-7, 40-2-2, 40-2-8

What an agreement needs. The agreement must be in writing, signed by both parties and acknowledged (notarized); the statute sets no waiting period and no counsel requirement, and disclosure matters through the enforcement test. A premarital agreement may not adversely affect a spouse’s right to support, so a waiver of alimony is not enforceable.
NMSA 1978, §§ 40-3A-3, 40-3A-4(B)

Chapter 29 explains one look and two, and what makes agreements stick.

Children (Article 8)

Child support: income shares. The basic obligation comes from a state schedule applied to both parents’ combined income, and each parent pays in proportion to income. Support lasts to 18, and to high school graduation if the child is under 19 and still attending. A court can enforce payment for education after high school only under a written agreement between the parents.
N.M. Stat. Ann. §§ 40-4-7(B)(3), 40-4-7(C), 40-4-11.1(G)

Moving away with a child. A parent with joint custody who plans to change home city or state must give the other parent 30 days’ written notice, and if they cannot agree, no major change occurs until it is resolved; the judge decides on the child’s best interests with no presumption for either parent. Earlier decisions presume a sole custodian’s move serves the child, and the other parent must show otherwise.
Jaramillo v. Jaramillo, 113 N.M. 57 (1991); Newhouse v. Chavez, 108 N.M. 319 (Ct. App. 1988); N.M. Stat. Ann. § 40-4-9.1(J)(3), (J)(4)(a)

Chapter 17 covers the children.

Getting out (Article 2)

How long you must live here before filing: six months. One spouse must have lived in New Mexico for at least six months right before filing and have a New Mexico domicile, meaning a home there and a good-faith intent to stay. Military members stationed in the state for six months count. Where the couple married or where the grounds arose does not matter.
N.M. Stat. Ann. § 40-4-5

How long it takes. Either spouse may petition for divorce on the ground of incompatibility, which exists when discord or conflict of personalities destroys the ends of the marriage and any reasonable expectation of reconciliation. No statute requires the other spouse’s consent, a separation period, or a waiting period after filing. The other spouse has 30 days to respond.
N.M. Stat. Ann. §§ 40-4-1, 40-4-2, 40-4-5; Pavletich v. Pavletich, 50 N.M. 224 (1946); Form 4A-100 NMRA

The legal minimum for a spouse who moves here alone and files as soon as allowed, with no minor children and the other spouse objecting, is about 180 days from arrival to a final decree (180 days of residence; no separation or statutory wait). Courts often take longer.

If you moved here from another state

Earnings from elsewhere count as community property, once you both live here. What either spouse acquired while living elsewhere is treated as community property at a divorce here if both spouses live in New Mexico when the case is brought. Before that statute, in 1978, New Mexico’s Supreme Court looked to Iowa law for earnings from Iowa.
N.M. Stat. § 40-3-8(C), (D); Hughes v. Hughes, 91 N.M. 339 (1978)

Chapter 22 covers what changes when you move.

Each entry on this page comes from the statute, rule or case it cites, read in September or November 2026, except where the entry says it has not been checked. A rule can change after that, and a rule on paper can play out differently in a particular courthouse. No lawyer reviews these pages.
