Overview
New Mexico adopted the Uniform Probate Code (UPC), making its probate system standardized and efficient. Probate cases in New Mexico can be filed in either the probate court (each county has one) for informal proceedings or the district court for formal proceedings.
New Mexico offers three main probate tracks:
- Small Estate Affidavit — for estates with personal property valued at $50,000 or less and no real property (with a special exception for a community property residence), no court filing required
- Informal Probate — handled through the county probate court with minimal court involvement, suitable for uncontested estates
- Formal Probate — court-supervised proceedings in district court, required when disputes arise or complexities demand judicial oversight
New Mexico is a community property state, meaning property acquired during marriage is generally owned equally by both spouses. When one spouse dies, only their half of community property is subject to probate.
New Mexico does not impose a state estate tax or inheritance tax, which simplifies administration for most families.
When Probate is Required
Probate is required in New Mexico when a decedent owned assets in their sole name that do not transfer automatically at death. Common examples include:
- Real property titled solely in the decedent's name or as tenants in common
- Bank accounts and investments without payable-on-death (POD) or transfer-on-death (TOD) designations
- Vehicles and titled personal property in the decedent's sole name
- Business interests held individually
- The decedent's half of community property without survivorship provisions
Probate is generally not required for:
- Community property with right of survivorship — passes automatically to the surviving spouse
- Joint tenancy property — passes automatically to the surviving joint tenant(s)
- Beneficiary-designated assets — life insurance, retirement accounts, POD/TOD accounts
- Property held in a revocable living trust
- Small personal estates valued at $50,000 or less — these can be handled with a small estate affidavit
- Community property residence valued at $500,000 or less for property tax purposes — can be transferred via affidavit
New Mexico's community property laws and small estate affidavit option allow many families to avoid full probate.
Small Estate Options
New Mexico provides a small estate affidavit process that allows successors to collect personal property without opening a probate case.
Eligibility requirements:
- The total value of the estate, less liens and encumbrances, must not exceed $50,000
- At least 30 days must have passed since the decedent's death
- No application or petition for appointment of a personal representative is pending or has been granted
Special provision for community property residence:
New Mexico has a unique provision allowing a surviving spouse to transfer the community property principal residence (valued at $500,000 or less for property tax purposes) through an affidavit, with a 6-month waiting period after death.
How the process works:
- The successor prepares a small estate affidavit stating their right to the property
- The affidavit is signed under oath before a notary public
- The completed affidavit is presented directly to banks, financial institutions, or others holding the decedent's property
- The institution must release the property to the affiant upon receiving the valid affidavit
- No court filing is required for the personal property affidavit
Important limitations:
- The standard affidavit does not transfer real property (other than the community property residence exception)
- The affiant becomes personally liable for claims and debts of the estate up to the value of property received
- If disputes exist among heirs, formal probate may be necessary
Step-by-Step Process
1. Determine the appropriate probate track
Assess the estate's assets, value, and circumstances. Use the small estate affidavit for personal property under $50,000. Use informal probate through the county probate court for uncontested estates. Use formal probate in district court for contested or complex matters.
2. File the application or petition
For informal probate, file an application with the county probate court in the county where the decedent was domiciled. Use Forms 4B-021 (testate) or 4B-022 (intestate). The filing fee is $30. For formal probate, file a petition with the district court.
3. Appointment of personal representative
In informal probate, the probate judge reviews the application and issues a Statement of Informal Probate and Letters appointing the personal representative. No hearing is required.
In formal probate, the district court schedules a hearing and appoints the personal representative after proper notice.
4. Accept appointment
File the Acceptance of Appointment to formally accept the role and its fiduciary duties.
5. Publish notice to creditors
Publish a Notice to Creditors in a newspaper of general circulation in the county. Creditors have 2 months from the date of first publication to present claims.
6. Notify known creditors
Mail or deliver written notice to all known creditors within a reasonable time after appointment.
7. Collect and inventory assets
Gather all estate assets and prepare a comprehensive inventory. Identify community property vs. separate property, as only the decedent's share of community property is subject to probate.
8. Pay debts, claims, and taxes
Review and pay valid creditor claims in priority order. File the decedent's final federal and New Mexico state income tax returns. New Mexico has no state estate tax.
9. File the closing statement
For informal probate, file a Closing Statement after all debts are paid and assets distributed. For formal probate, file a petition for final settlement.
10. Distribute assets to beneficiaries
Distribute remaining assets according to the will or New Mexico's intestacy laws. Obtain receipts from beneficiaries.

Unique State Rules
Community property state
New Mexico is one of nine community property states. Property acquired during marriage is generally owned equally by both spouses. When one spouse dies, only the decedent's one-half interest in community property is subject to probate. The surviving spouse's half passes automatically, significantly reducing the size of the probate estate.
Dual court system for probate
New Mexico has a unique dual-court system: informal probate is handled by the county probate court (with a low $30 filing fee), while formal probate is handled by the district court. This gives families an accessible, low-cost option for uncontested estates.
Community property residence affidavit
New Mexico allows a surviving spouse to transfer the community property principal residence through an affidavit if the property is valued at $500,000 or less for property tax purposes. There is a 6-month waiting period after death. This unique provision can help surviving spouses avoid probate for the family home.
No state estate tax or inheritance tax
New Mexico does not impose a state estate tax or inheritance tax. Only the federal estate tax applies for very large estates.
UPC state
New Mexico adopted the Uniform Probate Code, providing standardized procedures for informal and formal probate. The UPC emphasizes flexibility and reduced court involvement for routine estates.
$30 probate court filing fee
New Mexico's $30 filing fee for informal probate in the county probate court is one of the lowest in the country, making probate accessible for all families.
Two-month creditor claim period
New Mexico's creditor claim period is 2 months from the date of first publication — one of the shorter periods among states, helping estates close more quickly.
