Who Inherits When There Is No Will in New Mexico
Here is exactly how New Mexico divides an estate when there is no will:
| If the person leaves… | Who inherits in New Mexico |
|---|---|
| Spouse, no children | The surviving spouse inherits the decedent’s entire half of community property plus all of the decedent’s separate property. The spouse already owns their own half of community property outright as a community property state. |
| Spouse + shared children | New Mexico does NOT distinguish between shared children and stepchildren. With any surviving descendants: the spouse inherits all of the decedent’s half of community property plus one-fourth (1/4) of the decedent’s separate property. The descendants inherit three-fourths (3/4) of the decedent’s separate property by representation. |
| Spouse + children from another relationship | Same as shared children — New Mexico makes no distinction. The surviving spouse inherits all of the decedent’s half of community property plus one-fourth (1/4) of the decedent’s separate property. The descendants inherit three-fourths (3/4) of the decedent’s separate property by representation. |
| Children, no spouse | The children (descendants) inherit the entire intestate estate by representation. |
| No spouse, no children | The estate passes in this order: (1) to the decedent’s parents equally, or to the surviving parent; (2) if no parents, to descendants of parents (siblings, nieces, nephews) by representation; (3) if none, half to paternal grandparents or their descendants and half to maternal grandparents or their descendants by representation; (4) if relatives exist on only one side, that side takes the entire estate; (5) if no other taker, to descendants of a deceased spouse by representation. |
| No living relatives (escheat) | The estate escheats to the State of New Mexico only if there is no taker under any provision of Article 2. Net proceeds go to the current school fund. Per Section 45-2-105. |
These shares come from New Mexico intestate-succession law (NMSA 1978 Section 45-2-102 (Share of the Spouse) and Section 45-2-103 (Share of Heirs Other Than Surviving Spouse)).
How New Mexico divides shares among descendants: Per capita at each generation (the modern UPC approach), not strict per stirpes. Under Section 45-2-106, the estate is divided at the nearest generation with living members, and shares of deceased members in that generation are combined and redistributed equally among the next generation of surviving descendants.
New Mexico homestead and family allowance: New Mexico does NOT have a separate homestead allowance. It provides a family allowance of 30000 to the surviving spouse (Section 45-2-402), or divided equally among minor/dependent children if no spouse. Also a personal property allowance of up to 15000 in household furniture, automobiles, furnishings, appliances, and personal effects to the surviving spouse or children (Section 45-2-403).
Both are exempt from and have priority over all claims against the estate and are in addition to any intestate share.
Half-blood relatives in New Mexico: Under Section 45-2-107, relatives of the half blood inherit the same share they would inherit if they were of the whole blood. No distinction between half-siblings and full siblings.

Assets That Pass Outside New Mexico Intestate Rules
Assets with named beneficiaries (life insurance, retirement accounts, payable-on-death accounts), property held in joint tenancy with right of survivorship, and assets in a living trust pass outside New Mexico intestate succession rules and are not part of the probate estate.
Other New Mexico intestacy rules: New Mexico is a community property state — the surviving spouse already owns their half of community property outright (it never enters the estate). Only the decedent’s half of community property plus all separate property constitutes the intestate estate.
A 120-hour (5-day) survival requirement applies under Section 45-2-104 — an heir who does not survive the decedent by 120 hours is deemed to have predeceased, established by clear and convincing evidence. Exception: the 120-hour rule does not apply if it would cause the estate to escheat. An individual in gestation at death is deemed living if the individual lives 120 hours after birth.
What Dying Without a Will in New Mexico Really Means
When someone dies without a will in New Mexico, the state’s intestate-succession law — not the family — decides who inherits. The shares above show exactly how New Mexico divides an estate when someone is dying without a will in New Mexico, and they often surprise people: a spouse may not automatically inherit everything.
Understanding dying without a will in New Mexico helps a family know what to expect before they walk into probate court. Remember that some assets pass outside these rules entirely, so the full picture of dying without a will in New Mexico depends on how each asset was titled.
