New Mexico Surviving Spouse Rights

New Mexico Surviving Spouse Rights exist because a will cannot cut a husband or wife out entirely. Every state protects a widow or widower with a share they may claim regardless of what the will says, plus allowances that come off the top before creditors and other heirs.

This guide gives the New Mexico answer in plain English: what the elective share is, the deadline to claim it, whether trusts and joint accounts count, the homestead, exempt-property and family allowances, what happens when the marriage came after the will, and what forfeits the rights. All facts are from New Mexico law, verified as of September 2026.

New Mexico Surviving Spouse Rights: At a Glance

Here are the New Mexico facts that decide most New Mexico surviving spouse rights claims:

Elective share	NONE. New Mexico has no spousal elective share or forced share statute — it is a community property state, and the surviving spouse’s protection comes from owning one-half of the community estate outright rather than from an election against the will. Under NMSA 1978 § 45-2-807, the decedent may direct by will only the decedent’s own one-half of the community property; the survivor’s half is not part of the probate estate. Claims about a New Mexico “one-third elective share” are not New Mexico law. The statutory protections that do override a will are the family allowance (§ 45-2-402) and the personal property allowance (§ 45-2-403).
Deadline to elect	NONE — because no elective share exists in New Mexico, there is no election filing and no election deadline. The deadlines that do matter are different: the family allowance and personal property allowance are claimed during estate administration through the personal representative, and an interested person aggrieved by the personal representative’s selection, payment, or failure to act may petition the court under NMSA 1978 § 45-2-405. A surviving spouse using the homestead affidavit route under § 45-3-1205 must wait until six months after the death to record it. No fixed statutory day-count deadline for claiming the allowances is set by § 45-2-402 or § 45-2-403; treat timing as governed by the administration and the creditor-claim schedule, and check with the court or a licensed attorney.
Counts non-probate assets (augmented estate)	NO. New Mexico has not enacted the Uniform Probate Code augmented estate provisions (UPC §§ 2-203 through 2-209 have no New Mexico counterpart), so there is no statutory pull-back of non-probate assets — revocable trusts, joint accounts, payable-on-death designations, or lifetime gifts — into an elective share base. New Mexico case law under the omitted spouse statute confirms the point: assets of an inter vivos revocable trust funded before death are not part of the probate estate and cannot be used to calculate or satisfy an omitted spouse’s intestate share (NMSA 1978 § 45-2-301). Community property tracing, not an augmented estate, is the mechanism that reaches transferred assets in New Mexico.
Community property state	YES. New Mexico is a community property state. Under NMSA 1978 § 45-2-807, upon the death of either spouse one-half of the community property belongs to the surviving spouse, and only the other half is subject to the decedent’s testamentary disposition; community property held in joint tenancy under NMSA 1978 § 40-3-8(B) is not subject to testamentary disposition at all and passes by survivorship. This automatic one-half replaces an elective share: the survivor cannot be disinherited from the community half no matter what the will says. Separate property, by contrast, may be willed away freely, subject only to the allowances and the omitted spouse rule.
Homestead allowance	NONE in the probate code — New Mexico’s UPC Part 4 has no homestead allowance (§ 45-2-404 is reserved). Separately, NMSA 1978 § 42-10-9 gives a homestead exemption of 60000 against attachment, execution, or foreclosure by a judgment creditor, raised to 300000 where the claimant’s spouse died within the two years before the exemption is claimed and the deceased spouse could have claimed it. Under NMSA 1978 § 45-3-1205, six months after death a surviving spouse may transfer title to a community-property homestead by recorded affidavit with the county clerk if the assessed value does not exceed 500000 and no probate is otherwise required.
Exempt property	15000. Under NMSA 1978 § 45-2-403 (personal property allowance), the surviving spouse is entitled from the estate to value not exceeding 15000, in excess of any security interests, in household furniture, automobiles, furnishings, appliances, and personal effects. If there is no surviving spouse, the decedent’s children who are devisees, who take under § 45-2-302, or who are intestate heirs take the same value jointly. The allowance is available notwithstanding contrary intent expressed in the will, and it abates in favor of the family allowance if the estate is too small to satisfy both.
Family allowance	30000. NMSA 1978 § 45-2-402 gives the surviving spouse a family allowance of 30000, a fixed sum rather than a “reasonable” amount and not tied to a set number of months of support. If there is no surviving spouse, each minor child and each dependent child takes 30000 divided by the number of minor and dependent children. The family allowance is exempt from and has priority over all claims against the estate, is payable notwithstanding contrary intentions in the will, and is in addition to any share passing by will or intestacy unless the will provides otherwise.
Court / filing	There is no election to file. Probate matters are filed either in the elected county probate court, which handles informal and uncontested administration, or in the district court of the county where the decedent was domiciled, which handles formal, supervised, and contested proceedings — including a § 45-2-405 petition disputing an allowance. A § 45-3-1205 homestead affidavit is recorded with the county clerk, not filed with a court. — No elective share petition exists in New Mexico. The related filings are a demand or request to the personal representative for the family allowance and personal property allowance under §§ 45-2-402 and 45-2-403; a Petition for Allowance or petition for appropriate relief under § 45-2-405 when the allowance is contested or unpaid; and the Affidavit of Successor / affidavit transferring title to homestead to surviving spouse under § 45-3-1205.

Why the Will Cannot Disinherit a Spouse in New Mexico

The law treats marriage as an economic partnership. A spouse who spent decades contributing to a household is not left to the mercy of a will written in anger, under pressure, or decades ago. In separate-property states the protection is the elective share: a fixed fraction of the estate the surviving spouse may take instead of whatever the will provides.

In community property states it is built in — half of everything acquired during the marriage already belongs to the survivor and never passes under the will at all. New Mexico uses one of those two systems, and the table above says which.

The right is personal to the spouse and must be claimed. Nothing happens automatically: a surviving spouse who does nothing takes what the will gives, even if that is nothing. The election has a deadline, it is filed in the probate court, and it is the single New Mexico surviving spouse rights fact that a grieving spouse most often learns too late.

The New Mexico Elective Share

NONE. New Mexico has no spousal elective share or forced share statute — it is a community property state, and the surviving spouse’s protection comes from owning one-half of the community estate outright rather than from an election against the will.

Under NMSA 1978 § 45-2-807, the decedent may direct by will only the decedent’s own one-half of the community property; the survivor’s half is not part of the probate estate. Claims about a New Mexico “one-third elective share” are not New Mexico law. The statutory protections that do override a will are the family allowance (§ 45-2-402) and the personal property allowance (§ 45-2-403).

The deadline: NONE — because no elective share exists in New Mexico, there is no election filing and no election deadline. The deadlines that do matter are different: the family allowance and personal property allowance are claimed during estate administration through the personal representative, and an interested person aggrieved by the personal representative’s selection, payment, or failure to act may petition the court under NMSA 1978 § 45-2-405.

A surviving spouse using the homestead affidavit route under § 45-3-1205 must wait until six months after the death to record it. No fixed statutory day-count deadline for claiming the allowances is set by § 45-2-402 or § 45-2-403; treat timing as governed by the administration and the creditor-claim schedule, and check with the court or a licensed attorney.

What counts: NO. New Mexico has not enacted the Uniform Probate Code augmented estate provisions (UPC §§ 2-203 through 2-209 have no New Mexico counterpart), so there is no statutory pull-back of non-probate assets — revocable trusts, joint accounts, payable-on-death designations, or lifetime gifts — into an elective share base.

New Mexico case law under the omitted spouse statute confirms the point: assets of an inter vivos revocable trust funded before death are not part of the probate estate and cannot be used to calculate or satisfy an omitted spouse’s intestate share (NMSA 1978 § 45-2-301). Community property tracing, not an augmented estate, is the mechanism that reaches transferred assets in New Mexico.

Community property: YES. New Mexico is a community property state. Under NMSA 1978 § 45-2-807, upon the death of either spouse one-half of the community property belongs to the surviving spouse, and only the other half is subject to the decedent’s testamentary disposition; community property held in joint tenancy under NMSA 1978 § 40-3-8(B) is not subject to testamentary disposition at all and passes by survivorship.

This automatic one-half replaces an elective share: the survivor cannot be disinherited from the community half no matter what the will says. Separate property, by contrast, may be willed away freely, subject only to the allowances and the omitted spouse rule.

Allowances the Spouse Gets on Top of the Will

Homestead: NONE in the probate code — New Mexico’s UPC Part 4 has no homestead allowance (§ 45-2-404 is reserved). Separately, NMSA 1978 § 42-10-9 gives a homestead exemption of 60000 against attachment, execution, or foreclosure by a judgment creditor, raised to 300000 where the claimant’s spouse died within the two years before the exemption is claimed and the deceased spouse could have claimed it.

Under NMSA 1978 § 45-3-1205, six months after death a surviving spouse may transfer title to a community-property homestead by recorded affidavit with the county clerk if the assessed value does not exceed 500000 and no probate is otherwise required.

Exempt property: 15000. Under NMSA 1978 § 45-2-403 (personal property allowance), the surviving spouse is entitled from the estate to value not exceeding 15000, in excess of any security interests, in household furniture, automobiles, furnishings, appliances, and personal effects. If there is no surviving spouse, the decedent’s children who are devisees, who take under § 45-2-302, or who are intestate heirs take the same value jointly.

The allowance is available notwithstanding contrary intent expressed in the will, and it abates in favor of the family allowance if the estate is too small to satisfy both.

Family allowance: 30000. NMSA 1978 § 45-2-402 gives the surviving spouse a family allowance of 30000, a fixed sum rather than a “reasonable” amount and not tied to a set number of months of support. If there is no surviving spouse, each minor child and each dependent child takes 30000 divided by the number of minor and dependent children.

The family allowance is exempt from and has priority over all claims against the estate, is payable notwithstanding contrary intentions in the will, and is in addition to any share passing by will or intestacy unless the will provides otherwise.

Married After the Will Was Signed

Under NMSA 1978 § 45-2-301,

a spouse who married the testator after the will was executed and is not provided for takes no less than the value of the intestate share he or she would have received had the testator died intestate — but only as to the portion of the estate that is neither devised to a child of the testator born before that marriage who is not a child of the surviving spouse,

nor devised to a descendant of such a child, nor passing under § 45-2-603 or § 45-2-604.

The spouse takes nothing under this section if the will was made in contemplation of the marriage or expresses an intention to be effective notwithstanding any subsequent marriage, or if the testator otherwise provided for the spouse outside the will with intent that it be in lieu of a testamentary provision.

Waiver and Disqualification in New Mexico

NMSA 1978 § 45-2-407 allows the rights to family allowance and personal property allowance, or either, to be waived wholly or partially, before or after marriage, by a written contract, agreement, or waiver signed by the surviving spouse.

A waiver is unenforceable if the survivor proves it was not executed voluntarily, or that it was unconscionable when executed and the survivor was not given fair and reasonable disclosure of the decedent’s property and obligations and did not voluntarily and expressly waive disclosure in writing. A waiver of “all rights” or a complete property settlement made after or in anticipation of separation or divorce waives both allowances.

Premarital agreements are separately governed by the Uniform Premarital Agreement Act, NMSA 1978 §§ 40-3A-1 to 40-3A-10, which requires a writing signed by both parties and applies the same voluntariness and unconscionability-plus-disclosure test in § 40-3A-7; independent counsel is not a statutory requirement.

What forfeits the rights: Under NMSA 1978 § 45-2-802, a person divorced from the decedent or whose marriage was annulled is not a surviving spouse unless remarried to the decedent at death; a decree of separation that does not terminate spousal status is not a divorce and does not disqualify.

Also excluded: a person who obtained or consented to a divorce or annulment decree not recognized as valid in New Mexico (unless the couple later remarried or lived together as spouses), a person who married a third party after an invalid decree obtained by the decedent, and a person who was party to a valid proceeding concluded by an order purporting to terminate all marital property rights.

NMSA 1978 § 45-2-803 bars a spouse who feloniously and intentionally kills the decedent. Mere abandonment or a pending, undecided divorce is not listed as a disqualifier.

If there is no will: With no will, NMSA 1978 § 45-2-102 gives the surviving spouse the decedent’s one-half of the community property plus all of the separate property if no descendants survive, or one-fourth of the separate property if the decedent left surviving descendants. The New Mexico dying-without-a-will guide linked below covers that in full.

Other New Mexico rules: New Mexico has no sliding-scale share by length of marriage and no dower, curtesy, or statutory life estate in the home. Community property held in joint tenancy under § 40-3-8(B) escapes the will entirely and passes by survivorship (§ 45-2-807). The § 42-10-9 homestead exemption jumps from 60000 to 300000 for a claimant whose spouse died within the prior two years.

Section 45-3-1205 permits a surviving spouse to clear title to a community-property homestead assessed at 500000 or less by affidavit six months after death, avoiding probate. Widely repeated claims of a New Mexico augmented estate, a nine-month election deadline, or a 15000 homestead allowance do not appear in New Mexico law; you may want to confirm current amounts with the court or a licensed New Mexico attorney.

Mistakes That Cost a Surviving Spouse in New Mexico

The first mistake is waiting. The election to take the statutory share has a deadline that runs from death or from the will’s admission, and the probate court cannot extend it for a spouse who did not know. The second is assuming the will is the whole picture.

A spouse who was left “the house” may be entitled to considerably more under the New Mexico surviving spouse rights rules — and may also be entitled to allowances the will never mentions.

The third mistake is signing something in the first weeks. A release, a family settlement, or a disclaimer offered by another heir can waive rights the spouse did not know they had. The last is overlooking a prenuptial agreement.

If one exists, it may have waived the elective share — but only if it met the state’s requirements for disclosure and fairness at the time, which is a question a lawyer should answer before anyone relies on it.

What to Expect When You Claim New Mexico Surviving Spouse Rights

Claiming New Mexico surviving spouse rights is a filing inside the probate case, not a separate lawsuit. The surviving spouse files the election and any allowance requests with the court, the personal representative calculates the estate the share is measured against, and the court resolves any dispute over what counts.

Where the will already gives the spouse more than the statutory share, the election is unnecessary and most spouses do not file one.

Two things surprise people. The first is how much depends on the calendar — the election deadline is short in some states and runs whether or not the spouse knew. The second is that the allowances are separate from the share and are paid first, ahead of creditors, which is often what keeps a surviving spouse in the home during the months the estate takes to settle.

Quick Answers: New Mexico Surviving Spouse Rights

What are New Mexico Surviving Spouse Rights if the will leaves the spouse nothing?

A statutory share — commonly a third to a half of the estate — plus allowances paid ahead of creditors. New Mexico Surviving Spouse Rights exist precisely for this case, but they must be claimed by a filing.

How long does a spouse have to claim New Mexico Surviving Spouse Rights?

A fixed period after death or after the will is admitted, set by statute. Missing it forfeits the statutory share, which is the most common way New Mexico surviving spouse rights are lost.

Do New Mexico Surviving Spouse Rights include assets in a trust?

In augmented-estate states, yes — trusts, joint accounts, and large gifts are added back before the share is calculated. In others, New Mexico surviving spouse rights reach only the probate estate.

What allowances come with New Mexico Surviving Spouse Rights?

A homestead allowance or the right to remain in the home, an exempt-property allowance for household goods and a car, and a family allowance during administration. These New Mexico surviving spouse rights are paid first.
