New Mexico Surviving Spouse Rights in Probate

New Mexico protects a surviving spouse in a way that looks different from most of the country. It does not hand the spouse a fixed percentage of the estate through an elective share. Instead, protection starts from ownership: New Mexico is a community property state, so the surviving spouse already owns half of what the couple built during the marriage. On top of that ownership, the probate code adds a family allowance and a personal property allowance, and intestacy gives the spouse a share of the decedent's separate property.

This guide explains what a surviving spouse actually receives in New Mexico, where those rights come from in statute, and which court handles the estate. New Mexico runs probate through two courts: the elected county Probate Court for informal, uncontested administration, and the District Court for formal, supervised, or contested matters under NMSA 1978, Section 45-1-302.

Overview of Spousal Rights

A New Mexico surviving spouse draws on several separate protections, and they stack rather than replace one another:

1. Community property ownership gives the spouse half of the community estate outright.
2. Family allowance provides a $30,000 protected amount ahead of most estate claims.
3. Personal property allowance sets aside another $15,000 of household and personal property.
4. Intestate share of separate property applies when the decedent left no will.
5. Homestead and community-property pass-through protect the family residence.

Each right is independent. The family allowance and the personal property allowance are in addition to any share the spouse takes by will or by intestate succession, unless the decedent provided otherwise in the will or another governing instrument (NMSA 1978, Sections 45-2-402 and 45-2-403). New Mexico does not use a classic elective share, and the reason is explained further below.

Community Property: The Spouse's Half

New Mexico sorts a married person's property into two kinds, and the difference decides what the estate can even touch.

• Community property is generally what the spouses acquired during the marriage through the work or earnings of either spouse. Each spouse already owns one-half of it.
• Separate property is generally what a spouse owned before marriage, or received during marriage by gift or inheritance. It belongs to that spouse alone.

Here is why this matters for a surviving spouse. Because each spouse already owns one-half of the community property, that half was never the decedent's to give away. The decedent could pass only the decedent's own one-half of the community property, plus the decedent's separate property. Your half of the community estate is yours by ownership, not by inheritance, so it does not depend on the will and does not have to be earned back through a court claim.

When a married New Mexican dies without a will, the decedent's one-half of the community property also passes to the surviving spouse under NMSA 1978, Section 45-2-102(B). Combined with the half you already own, that leaves the surviving spouse holding all of the community property. The part that can change is the separate property, which the Intestate Share of Separate Property section below explains.

Family Allowance

New Mexico gives the surviving spouse a family allowance of $30,000 under NMSA 1978, Section 45-2-402.

This is a flat statutory amount, not a monthly figure the court has to size to your budget. If there is no surviving spouse, the $30,000 is divided among the decedent's minor children and dependent children instead.

The family allowance is powerful because of its priority. It is exempt from and has priority over all claims against the estate, and it is paid on top of whatever the spouse receives by will or by intestacy (unless the will or governing instrument says otherwise). That means it can reach the spouse early in administration, ahead of general creditors. The $30,000 amount is set by statute and is not indexed to inflation, so it changes only when the Legislature amends it.

Personal Property Allowance

Separate from the family allowance, the surviving spouse may claim a personal property allowance of $15,000 under NMSA 1978, Section 45-2-403.

This allowance covers household furniture, automobiles, furnishings, appliances, and personal effects, up to $15,000 in value over any security interests on those items. If the qualifying personal property is worth less than $15,000, the spouse may claim other estate assets to make up the difference. Like the family allowance, this right has priority over claims against the estate, and it is in addition to any share the spouse takes by will or intestacy. If there is no surviving spouse, the decedent's children who are entitled to a share take the $15,000 jointly.

One ordering rule to know: if there are not enough qualifying assets to fill the personal property allowance, the right to reach other assets for the shortfall gives way as needed so the family allowance can be paid first (NMSA 1978, Section 45-2-403).

Homestead

New Mexico does not have a Florida-style rule that forces the home to a surviving spouse and voids a contrary will. Its homestead protection is a creditor exemption under NMSA 1978, Section 42-10-9. A person who owns and primarily lives in a residence may hold exempt a base amount of $150,000 of value in that homestead from judgment creditors and from executors or administrators in probate. The base amount rises to $300,000 if the claimant's spouse died within the two years before the claim and the deceased spouse could have claimed the exemption. These base figures are adjusted for inflation on a two-year cycle, so confirm the current amount before relying on a specific number.

New Mexico also has a convenience rule that helps a surviving spouse keep the home moving. When spouses hold the residence as community property and one spouse dies, either intestate or leaving the interest to the survivor, the homestead passes to the surviving spouse and no probate or administration of that homestead is necessary (NMSA 1978, Section 45-3-1205). Six months after the death, the surviving spouse may record a title-transfer affidavit with the county clerk, stating among other things that funeral and last-illness expenses and all unsecured debts are paid and that no estate tax is due. For this affidavit procedure, the homestead's full assessed value for property taxation must not exceed $500,000.

Intestate Share of Separate Property

When the decedent left no will, New Mexico intestacy under NMSA 1978, Section 45-2-102 decides the separate-property share. The community-property half still passes entirely to the surviving spouse under Section 45-2-102(B), so only the separate property changes based on family.

If the decedent left no children or other descendants, the surviving spouse takes everything: all of the community property and 100% of the separate property (NMSA 1978, Section 45-2-102(A)(1)). If the decedent did leave surviving descendants, the spouse still takes all of the community property, plus one-fourth of the separate property, and the remaining three-fourths of the separate property passes to the descendants by representation under NMSA 1978, Sections 45-2-102(A)(2) and 45-2-103.

New Mexico does not use the blended-family test that some states apply, where the spousal share drops only when the decedent had a child from outside the marriage. Here, the separate-property share turns simply on whether the decedent left any surviving descendants at all. For the full order of heirs, see the New Mexico intestate succession guide.

Why New Mexico Has No Elective Share

Some states let a surviving spouse "elect against the will" and take a fixed percentage of the estate no matter what the will says. New Mexico is not one of them. As a community property state, New Mexico protects the surviving spouse primarily through ownership rather than through an augmented-estate elective share.

The logic is that the spouse already owns one-half of the community property outright, so there is less need for a separate election to prevent disinheritance. In place of an elective percentage, a New Mexico surviving spouse analyzes community property ownership, the family allowance, the personal property allowance, and any intestate separate-property share together. Those protections often provide substantial support without an election.

Waiver and Forfeiture

Spousal protections are not absolute. They can be given up in advance or lost by conduct.

Prenuptial and postnuptial agreements. A valid marital agreement can waive or modify community property rights and the statutory allowances. A waiver generally must be in writing and signed voluntarily, and fair financial disclosure supports its validity. Have each spouse review a proposed waiver carefully before signing.

The slayer rule. A person who feloniously and intentionally kills the decedent forfeits any intestate share, elective benefit, allowance, and nonprobate benefit, and is treated as having disclaimed or predeceased the decedent under NMSA 1978, Section 45-2-803.

Divorce and annulment. Divorce or annulment generally revokes provisions and revocable nonprobate transfers in favor of a former spouse under NMSA 1978, Section 45-2-804. A former spouse is no longer a surviving spouse for these rights.

Deadlines

New Mexico attaches only a few firm timing rules to a surviving spouse's rights, and it is worth knowing them.

• 120-hour survival. To take as a surviving spouse or heir, the spouse must survive the decedent by 120 hours, which is five days, shown by clear and convincing evidence, or is treated as having predeceased the decedent (NMSA 1978, Section 45-2-104).
• Allowances during administration. The family allowance and the personal property allowance are determined and set apart as part of estate administration; NMSA 1978, Section 45-2-405 governs their source and documentation. Confirm any specific time limits before relying on them.
• Community-property homestead affidavit. The surviving spouse may record the title-transfer affidavit for a community-property homestead no earlier than six months after the death (NMSA 1978, Section 45-3-1205).

Because these rights are handled inside administration, the practical deadline is often set by the estate's own schedule. Ask the personal representative or the court clerk about the timeline in your case.

How Your Protections Stack

It helps to read the pieces in order rather than as competing choices, because in New Mexico they add together:

1. Start with ownership. You already hold one-half of the community property. That half is yours regardless of the will.
2. Add the decedent's community half if there is no will. Under NMSA 1978, Section 45-2-102(B), the decedent's one-half of the community property also passes to you, so you hold all of it.
3. Add the family allowance of $30,000 and the personal property allowance of $15,000. Both are paid ahead of general estate claims and stack on top of your other shares.
4. Add your separate-property share. With no surviving descendants you take all of the decedent's separate property; with descendants you take one-fourth and they take three-fourths.
5. Consider the home. If the residence is community property, the community-property homestead pass-through can move title to you without administration, and the homestead creditor exemption shields a base amount from judgment creditors.

Working the list in that order shows why a surviving spouse in New Mexico is often well protected even though the state has no elective share.

Frequently Asked Questions

Can my spouse disinherit me in New Mexico?

Not fully. You already own your one-half of the community property by ownership, and a will cannot give that half away. On top of that, you may claim the $30,000 family allowance and the $15,000 personal property allowance, which are paid ahead of most estate claims. A will can direct the decedent's own one-half of the community property and the decedent's separate property elsewhere, but it cannot erase your ownership half or the allowances.

Does New Mexico have an elective share?

No. New Mexico protects the surviving spouse through community property ownership rather than a fixed elective-share percentage. You analyze your community property half, the family allowance, the personal property allowance, and any intestate separate-property share together instead of electing a set fraction of the estate.

How much are the New Mexico spousal allowances?

The family allowance is $30,000 under NMSA 1978, Section 45-2-402, and the personal property allowance is $15,000 under NMSA 1978, Section 45-2-403. They are separate amounts, both have priority over estate claims, and both are in addition to what you take by will or intestacy unless the governing instrument provides otherwise.

What do I inherit if my spouse died without a will?

You take all of the community property under NMSA 1978, Section 45-2-102(B). For the separate property, you take the entire separate estate if the decedent left no descendants, or one-fourth of it if the decedent left surviving descendants, with the other three-fourths passing to those descendants.
