Settling an Estate in New Mexico
Reviewed by DocDraft Legal Team · New Mexico · Last updated August 27, 2026
New Mexico is the rare state that runs estate administration out of two different courthouses. An uncontested estate is opened in the Probate Court of the county where the decedent was domiciled, a county court created by Article VI, Section 23 of the New Mexico Constitution, where the filing fee is $30 and the constitution leaves the qualifications of the probate judge to the legislature. The moment a matter becomes formal or contested, or turns on title to or boundaries of land, it belongs to the District Court, which NMSA 1978 Section 45-1-302 gives exclusive original jurisdiction over formal proceedings. New Mexico is also a community property state, so a surviving spouse already owns half of the community estate before any court is involved. The affidavit in NMSA 1978 Section 45-3-1201 reaches an estate of $50,000 or less and cannot be used to perfect title to real estate, but a separate affidavit lets a surviving spouse move a primary residence assessed at $500,000 or less without opening probate at all.

Is probate required in New Mexico, and when can it be avoided?
Not always. Property held in joint tenancy, real estate covered by a recorded transfer on death deed, payable on death accounts, and beneficiary designated brokerage accounts pass outside probate. New Mexico also offers a $50,000 affidavit for personal property and a separate affidavit letting a surviving spouse take the primary residence.
Which court hears a New Mexico probate case?
Two courts share the work. An uncontested case is filed with the Probate Court of the county where the decedent was domiciled, a county court created by Article VI, Section 23 of the state constitution. Formal and contested matters belong to the District Court under NMSA 1978 Section 45-1-302.
What is the small estate affidavit limit in New Mexico?
NMSA 1978 Section 45-3-1201 sets it at $50,000, measured as the value of the entire estate wherever located, less liens and encumbrances. Thirty days must pass after death and no probate can be pending. Real property is excluded, because the affidavit cannot be used to perfect title to real estate.
How long does settling an estate take in New Mexico?
Most uncontested estates run six months to a year. A probate case cannot be closed until it has been open at least three months, and claims are not barred until four months after first publication or sixty days after mailed notice, whichever falls later. Contested District Court cases take longer.
Two courthouses, a $50,000 affidavit, and a $500,000 residence affidavit for the surviving spouse
The first question in a New Mexico estate is not which procedure to use but which building to walk into. Article VI, Section 23 of the New Mexico Constitution creates a probate court in each county and then limits it sharply: it has jurisdiction over the administration of estates and over determinations of heirship as to real property, but it is expressly denied jurisdiction over questions of title to or boundaries of land other than heirship, over actions for the possession of land, and over injunctive relief and extraordinary writs. NMSA 1978 Section 45-1-302 completes the division by giving the probate court and the district court original jurisdiction over informal proceedings, while reserving to the district court exclusive original jurisdiction over formal proceedings, including determinations of testacy, construction of wills, and the administration and expenditure of estate funds, and the power to determine title to and value of property as between the estate and any interested person. The constitution leaves the qualifications of probate judges to the legislature, and the probate courts are designed to help non lawyers with cases that do not need to be filed in district court, with a filing fee of $30. The practical result is that an uncontested New Mexico estate is cheap and quick to open in the county Probate Court, and a fight over a will, an heir, or a boundary line moves the file to the District Court. New Mexico is also one of the community property states, so under NMSA 1978 Section 45-2-102 an intestate surviving spouse takes one half of the community property over which the decedent had testamentary power of disposition, plus the entire separate intestate estate where there is no surviving issue or one fourth of it where there is. Two affidavits sit below the court process. Section 45-3-1201 allows collection of an estate of $50,000 or less, valued wherever located and net of liens and encumbrances, thirty days after death and only where no probate is pending, and it cannot perfect title to real estate. Section 45-3-1205 is New Mexico's answer to that carve out: six months after death, where no probate has been filed and the only item to be transferred is the decedent's primary residence held as community property or devised to the spouse, the surviving spouse may record an affidavit with the county clerk where the residence sits if the full value assessed for property tax purposes does not exceed $500,000.
Relevant Laws
NMSA 1978 Section 45-1-302 (Subject matter jurisdiction of district and probate courts)
The provision that splits New Mexico probate between two courts. The probate court and the district court share original jurisdiction over informal proceedings for probate of a will or appointment of a personal representative. The district court has exclusive original jurisdiction over formal proceedings, including determinations of testacy, construction of wills, and the administration and expenditure of estate funds, and full power to determine title to and value of real or personal property as between the estate and any interested person.
NMSA 1978 Sections 45-3-1201 and 45-3-1205 (Small estate affidavit and affidavit of surviving spouse)
A small estate is one where the total estate is worth $50,000 or less and does not include any real property, collectible by affidavit of successor in interest under Section 45-3-1201 once thirty days have passed and no probate has been filed. Section 45-3-1205 separately allows a surviving spouse to transfer the decedent's primary residence by affidavit filed with the county clerk six months after death, where no probate has been filed, the residence is the only item to be transferred, it was community property or was devised to the spouse, and its full assessed value does not exceed $500,000.
NMSA 1978 Sections 45-3-801 to 45-3-803 and Form 4B-501 NMRA (Notice to creditors)
The Supreme Court approved notice to creditors form, captioned for the county Probate Court, requires all persons having claims against the estate to present them within four months after the date of the first publication of any published notice to creditors, or sixty days after the date of mailing or other delivery of the notice, whichever is later, or the claims are forever barred. Claims may be presented to the personal representative directly or filed with the Probate Court of the county.
NMSA 1978 Section 45-2-102 (Intestate share of the surviving spouse)
New Mexico's intestacy rule for a married decedent and the clearest statement of its community property character. The surviving spouse takes one half of the community property over which the decedent had testamentary power of disposition. As to separate property the spouse takes the entire intestate estate if the decedent left no surviving issue, or one fourth of the intestate estate if there is surviving issue.
Regional Variances
New Mexico probate track table
Entire estate $50,000 or less with no real property
Affidavit of successor in interest under NMSA 1978 Section 45-3-1201, available thirty days after death where no probate has been filed. Presented to banks and to the Motor Vehicle Division rather than to a court, so no filing fee, no bond, no inventory, and no creditor publication. The affidavit cannot be used to perfect title to real estate, so any land or house is outside it.
Primary residence assessed at $500,000 or less, surviving spouse only
Affidavit of surviving spouse under NMSA 1978 Section 45-3-1205, available six months after death. Requires that no probate has been filed, that the residence is the only item needing transfer, and that it was community property or was left to the spouse by will. It is notarized and filed with the county clerk where the residence sits, not with a court, and no creditor window runs.
Uncontested estates above the affidavit routes
Informal probate in the Probate Court of the county where the decedent was domiciled, which shares original jurisdiction over informal proceedings with the district court under NMSA 1978 Section 45-1-302. The filing fee is $30. Letters testamentary or letters of administration issue, the creditor notice runs, and the case closes on a sworn statement under Section 45-3-1003.
Formal, contested, or land title matters at any size
District Court, exclusively. NMSA 1978 Section 45-1-302 reserves formal proceedings, determinations of testacy, will construction, and disputes over title to and value of property to the district court. Article VI, Section 23 of the New Mexico Constitution separately denies the probate court jurisdiction over title and boundary questions other than heirship, actions for possession of land, and injunctive or extraordinary relief.
New Mexico deadlines and mechanics
Creditor claims
Four months after the date of first publication of any published notice to creditors, or sixty days after the date of mailing or other delivery of written notice, whichever is later, per Form 4B-501 NMRA and NMSA 1978 Sections 45-3-801 to 45-3-803. Because the test is whichever is later, a late mailing to a known creditor extends that creditor's window past the published date. Claims may be filed with the county Probate Court itself.
Window to open the case
A probate case may be filed between five days and three years after the death. After three years a case may still be filed under NMSA 1978 Section 45-3-108, but only for the limited purpose of transferring title to real property from the decedent's name to the heirs, which is a narrower remedy than a full administration.
Inventory and closing
NMSA 1978 Section 45-3-706 requires the personal representative to prepare an inventory within three months after appointment, listing property in reasonable detail with its estimated value at the date of death and the type and amount of any encumbrance. The representative may file the original with the court and must send a copy to interested persons who request it. Closing is by sworn statement under Section 45-3-1003, and the case must be open at least three months first.
Spousal entitlement
Community property rather than a percentage elective share against the whole estate. Half of the community property already belongs to the survivor and is not part of the decedent's estate. NMSA 1978 Section 45-2-102 then gives an intestate surviving spouse one half of the community property over which the decedent had testamentary power, and either all of the separate intestate estate where there is no issue or one fourth of it where there is.
Suggested Compliance Checklist
Decide which New Mexico courthouse the estate belongs in
Week 1 days after startingBefore choosing any procedure, decide whether this is a county Probate Court case or a District Court case. NMSA 1978 Section 45-1-302 leaves the district court exclusive original jurisdiction over formal proceedings, contested testacy, will construction, and title disputes, and Article VI, Section 23 of the constitution withholds land title, boundary, possession, and injunctive matters from the probate court. Filing in the wrong court wastes the fee and the weeks.
Separate community property from separate property, then test both affidavits
Weeks 1-3 days after startingMark each asset community or separate, since the surviving spouse already owns half of the community property and only the decedent's share belongs to the estate. Then compare the estate against the $50,000 ceiling in NMSA 1978 Section 45-3-1201, net of liens and encumbrances, and separately check whether the Section 45-3-1205 residence affidavit fits. Overstating community assets can wrongly push a qualifying estate above the affidavit limit.
Prepare the affidavit of successor in interest if the estate qualifies
Day 30 or later days after startingNMSA 1978 Section 45-3-1201 requires that thirty days have passed since the death, that no probate has been filed, and that the entire estate wherever located, less liens and encumbrances, is within the $50,000 ceiling. The affidavit is signed by the person entitled to the property and notarized, then presented to banks or the Motor Vehicle Division. Confirm first that the estate holds no real property, because the affidavit cannot perfect title to real estate.
Publish and mail the notice to creditors, and diary both dates
As soon as letters issue days after startingUse Form 4B-501 NMRA and calendar four months from the date of first publication and sixty days from each mailing or delivery to a known creditor, because the bar falls on whichever is later. A representative who distributes before that later date has no protection against a timely claim and can end up answering for it personally, since money already spent by a beneficiary is rarely recoverable.
Prepare the inventory within three months of appointment
Within 3 months of appointment days after startingNMSA 1978 Section 45-3-706 requires an inventory of property owned at death within three months after appointment, listed in reasonable detail with its estimated value as of the date of death and the type and amount of any encumbrance. The original may be filed with the court, and a copy must go to any interested person who requests it. Appraisals are worth obtaining for real property and closely held business interests.

Frequently Asked Questions
The dispute has to move. NMSA 1978 Section 45-1-302 gives the district court exclusive original jurisdiction over formal proceedings, including contested determinations of testacy and appointment, will construction, and determining title to and value of property as between the estate and an interested person. Article VI, Section 23 of the constitution separately withholds land title, boundary, and possession questions from the probate court. The Probate Court will inform filers when a case must go to District Court.
Sometimes, through the affidavit in NMSA 1978 Section 45-3-1205. It requires that at least six months have passed since the death, that no probate has been filed, that the only item needing transfer from the estate is the decedent's primary residence, that the residence was community property or was left to the spouse by will, and that its full value as assessed for property tax purposes does not exceed $500,000. The signed and notarized affidavit is filed with the county clerk where the residence is located.
Filing a probate case in Probate Court costs $30, which is among the lowest opening fees in the country and reflects that the county probate courts are built for self represented filers. Beyond the filing fee, the estate carries publication charges, recording fees, and any attorney fees. A personal representative is entitled to reasonable compensation from the estate under NMSA 1978 Section 45-3-719 and should keep a written record of tasks and time.
NMSA 1978 Section 45-2-102 treats the two property types separately, which is what makes a community property state different. The surviving spouse takes one half of the community property over which the decedent had testamentary power of disposition. As to separate property, the spouse takes the entire intestate estate where the decedent left no surviving issue, and one fourth of the intestate estate where there is surviving issue, with the balance passing to the descendants.
Yes, and it runs at both ends. A probate case may be filed any time between five days and three years after the death. After the three year period a case may still be filed, but only for the limited purpose of transferring title to real property out of the decedent's name into the heirs, under NMSA 1978 Section 45-3-108. Waiting that long forfeits the ordinary administration route.
