Do I Need Probate in New Mexico?

Whether the house needs probate often turns on one label: community property, or separate property.

NMSA §45-2-807, 45-6-405

By the FigureMyTax Editorial Team · Reviewed 2026 · How we calculate

Quick answer: a surviving spouse's community-property residence at or under $500,000, 6 months passed — the special affidavit. Personal property only, at or under $50,000, 30 days passed — the general affidavit. Separate property, a larger home, or no surviving spouse — probate or a trust.

Community property versus separate property decides everything

Worth knowing: community property was generally acquired during the marriage and is owned equally by both spouses; separate property was typically owned before marriage or received individually by gift or inheritance. New Mexico's defining feature for inherited real estate is that the surviving spouse already owns half of all community property by law, so the state doesn't use the kind of elective-share system found in many other states.

A basis benefit worth planning around

Both halves of qualifying community property can receive a stepped-up basis when the first spouse dies, not just the deceased spouse's half — a genuine federal tax advantage that can erase most or all of the taxable gain when the surviving spouse eventually sells.

What skips probate before any threshold matters

A Transfer on Death deed, joint tenancy with right of survivorship, and named beneficiary designations all pass outside of probate entirely, on top of the surviving spouse's own automatic half of community property.

The decision, in order

  1. Is the asset covered by a TOD deed, joint titling, or a beneficiary designation? → Skips probate entirely.
  2. Is it a surviving spouse's community-property residence, at or under $500,000, 6 months passed? → Community-property homestead affidavit.
  3. Personal property only, at or under $50,000, 30 days passed? → Small estate affidavit.
  4. None of the above fits → Probate through the county Probate Court or District Court.

Do I need probate — frequently asked questions

Does owning a New Mexico house always mean probate is required?

Not necessarily for a surviving spouse — a community-property residence valued at $500,000 or less can transfer through a special affidavit instead, though separate property or a larger home still needs probate or a trust.

What's the practical difference between community property and separate property here?

Community property was generally acquired during the marriage and is owned equally by both spouses; separate property was typically owned before marriage or received individually by gift or inheritance, and it doesn't qualify for the special spousal affidavit.

What is the community property basis step-up, and why does it matter for a later sale?

Both halves of qualifying community property can receive a stepped-up basis when the first spouse dies, not just the deceased spouse's half — which can erase most or all of the federal taxable gain when the surviving spouse eventually sells.

What assets skip New Mexico probate regardless of these thresholds?

A Transfer on Death deed, joint tenancy with right of survivorship, and named beneficiary designations all pass outside of probate entirely, on top of the surviving spouse's own automatic half of community property.

When do I need probate in New Mexico, and when can I skip it?

A surviving spouse's community-property residence at or under $500,000, 6 months passed — the special affidavit. Personal property only, at or under $50,000, 30 days passed — the general affidavit. Separate property, a larger home, or no surviving spouse — probate or a trust. Check your own numbers with the New Mexico small estate checker.
