How to Handle New Mexico Probate Without a Lawyer
New Mexico law explicitly permits executors to handle informal probate without an attorney. The state judiciary provides standardized 4B-series forms precisely because the legislature designed informal county probate as an administrative — not adversarial — process. Most New Mexico probates are uncontested informal proceedings that proceed without a single courtroom appearance.
The executor who attempts this without a structured plan, however, runs a real risk. Personal liability in New Mexico probate is not theoretical. Distribute assets before the four-month creditor window closes, pay debts in the wrong priority order, or miss the 10-day Medicaid reporting window, and the consequences fall on the executor personally — not the estate.
This page explains exactly how to handle New Mexico informal probate without a lawyer: the process, the forms, the deadlines, and the specific situations where you must stop and hire counsel.
Before You Start: Determine Which Process You Are Actually In
The first error most executors make is assuming "probate" means one thing. New Mexico has four distinct pathways, and three of them do not require probate at all:
Is the total solely owned personal property (minus liens) $50,000 or less? If yes, and 30 days have passed since the date of death with no pending court petitions, the estate qualifies for the Small Estate Affidavit under NMSA § 45-3-1201. No court filing. No letters. No months-long administration. You file an affidavit with financial institutions and the Motor Vehicle Division to transfer personal property. Note: this pathway cannot transfer real estate.
Is the primary asset a family home held as community property, assessed at $500,000 or less, with the surviving spouse as transferee? If yes, the Homestead Affidavit under NMSA § 45-3-1205 transfers the property after a six-month waiting period without any court involvement. All debts and funeral expenses must be paid first.
Does the estate not qualify for either affidavit, and is it uncontested? Informal probate in the county probate court. This is the DIY track. $30 filing fee, no hearings, administrative process. Read on.
Is the will contested, or has a formal proceeding been triggered? Formal probate in the district court. Stop here and retain an attorney. This page is not for formal proceedings.
Step-by-Step: How to Handle Informal Probate Without a Lawyer
Step 1: Gather the Required Documents
Before filing anything, collect:
- The original Last Will and Testament (if one exists). You need the original — not a photocopy. If the will is self-proved (contains a notarized self-proving affidavit under NMSA § 45-2-504), the court does not need to locate witnesses to authenticate it. If it is not self-proved, the court may require additional steps.
- Certified copies of the death certificate. Order 10-15 copies from the New Mexico Department of Health Bureau of Vital Records. The fee is $5.00 per copy. Every financial institution, government agency, and property transfer will demand an original certified copy — photocopies are routinely rejected.
- The decedent's Social Security number, date and place of birth, address at death, and the names and addresses of all known heirs and beneficiaries.
Step 2: File the Application to Open the Case
Go to the probate court in the county where the decedent was domiciled at death. If the decedent had no New Mexico domicile but owned property in the state, file in the county where the property is located.
- For a testate estate (with a will): File Form 4B-302 (Application for Informal Probate and Appointment of Personal Representative — Testate) along with the original will and a certified death certificate.
- For an intestate estate (no will): File Form 4B-301 (Application for Informal Appointment of Personal Representative — Intestate) with a certified death certificate.
- Pay the $30 filing fee.
The probate judge reviews the application to confirm procedural compliance and venue. In informal proceedings, this is an administrative review — no hearing is required.
Step 3: Receive Your Appointment and Letters
Once the court approves the application:
- The judge issues Form 4B-303 or 4B-304 (Order of Informal Appointment).
- You sign Form 4B-305 (Acceptance of Appointment), formally accepting your fiduciary duties.
- The court issues your Letters: Form 4B-306 (Letters Testamentary) for a testate estate, or Form 4B-307 (Letters of Administration) for an intestate estate.
These Letters are the document everything else depends on. Banks will not release funds without them. Agencies will not cooperate. Real estate cannot be conveyed. Get multiple certified copies — you will hand them out frequently.
Step 4: Open an Estate Bank Account
Open a dedicated estate checking account using the estate's Employer Identification Number (EIN), which you obtain from the IRS (Form SS-4, or online in minutes). All estate funds go into this account. Do not mix estate money with personal accounts — commingling is a fiduciary breach that can create personal liability.
Step 5: Notify Heirs Within 30 Days
Within 30 days of your appointment, send Form 4B-401 (Notice of Informal Appointment) to all heirs and devisees named in the will, and to all persons who would inherit if there were no will. Keep records of when each notice was mailed. File Form 4B-402 (Proof of Notice) with the court confirming the notifications were sent.
Step 6: Publish Notice to Creditors
Publish Form 4B-501 (Notice to Creditors) in a newspaper of general circulation in the county where the probate is pending, once per week for three consecutive weeks. This opens the four-month creditor claim window. Unknown creditors who do not file within four months from the first publication date have their claims permanently barred under NMSA § 45-3-803.
Simultaneously, send direct written notice to every creditor you are aware of or can reasonably identify. Creditors receiving direct notice have 60 days from the mailing date (or four months from first publication, whichever is later) to file their claim.
Keep the newspaper affidavits of publication. You will need them at closing.
Step 7: Notify Medicaid Within 10 Days if Required
If the decedent was 55 or older and received Medicaid-funded long-term care, nursing facility services, or home and community-based services, you must notify the local Income Support Division office within 10 calendar days of the death under state administrative rules. This is the tightest deadline in the entire process — far tighter than any court deadline.
The New Mexico Health Care Authority (formerly the Human Services Department) will mail a recovery notice and file a claim against the estate for the medical assistance paid. However, recovery is deferred or waived if the decedent is survived by a spouse, a child under 21, a blind child, or a permanently disabled child. Undue hardship waivers are available in specific circumstances. The executor does not need an attorney to navigate the basic recovery process — but if the claim is disputed or a hardship waiver is needed, consider consulting a benefits counselor.
Step 8: Complete the Inventory Within 90 Days
Within 90 days of appointment, prepare Form 4B-601 (Inventory) listing every probate asset at its fair market value as of the date of death, with all liens and encumbrances noted. Provide a copy to any heir who requests it.
What is a probate asset? Property titled solely in the decedent's name with no beneficiary designation or joint ownership structure. What is not a probate asset? Life insurance with a named beneficiary, retirement accounts with a named beneficiary, payable-on-death bank accounts, real estate held in joint tenancy, property in a trust, and — critically for married decedents in New Mexico — the surviving spouse's one-half of community property.
For real estate, get a professional appraisal. For mineral rights or oil and gas interests, engage a qualified petroleum landman. Valuation disputes among heirs are far more likely when appraisals are absent.
Step 9: Pay Claims in Statutory Priority Order
After the four-month creditor window closes, pay valid claims in this exact order (NMSA § 45-3-805):
- Family allowance ($30,000) — surviving spouse, or minor/dependent children if no spouse
- Personal property allowance ($15,000) — same recipients
- Funeral and last illness expenses
- Administrative expenses (your executor fees, attorney fees if any, court costs)
- State and federal taxes
- General unsecured creditors
Do not pay general creditors before paying the family allowance. Do not distribute assets to heirs before the creditor window closes. Both errors create personal liability for the executor — not the estate, you personally.
If the estate has a Gross Receipts Tax obligation from a sole proprietorship or business, request a formal Tax Clearance (Form ACD-31096) from the New Mexico Taxation and Revenue Department before distributing. A standard "Letter of Good Standing" is not sufficient.
Step 10: Distribute Assets
After debts and taxes are paid, distribute the remaining assets according to the will (testate) or NMSA § 45-2-102 (intestate). Get signed receipts from all distributees before releasing anything. These receipts protect you if a beneficiary later claims they did not receive their share.
For real estate transfers, a Personal Representative's Deed is required. This deed carries title implications that benefit from a real estate attorney's review even if you are handling everything else yourself. Have it drafted by a licensed real estate attorney in New Mexico.
Step 11: Close the Estate
File Form 4B-701 (Verified Closing Statement) with the probate court. This sworn document certifies that you have:
- Published the creditor notice and the claim period has closed
- Paid all debts, taxes, and allowances in the correct priority order
- Distributed all remaining assets
- Accounted for the estate's administration
Mail a copy to all distributees and to any creditors with unsatisfied claims. If no legal proceedings are initiated against you within one year of filing the closing statement, your appointment terminates and you are released from personal liability.
What You Cannot Handle Without a Lawyer
Stop and retain an attorney if any of these develop:
- A beneficiary contests the will — formal district court proceedings require representation
- The estate is transferred to district court under NMRA Rule 1B-701
- A creditor files a claim that you dispute and cannot resolve informally
- The estate involves trust land or restricted property of a tribal member — jurisdiction falls to the BIA, not state courts
- You discover the decedent owned an operating business requiring active management
- Blended family disputes over community property classification are threatening litigation

The Hidden Cost of Doing It Wrong
New Mexico informal probate is designed to be accessible. But the executor's liability under New Mexico law is absolute. These are the errors with the worst consequences:
Distributing before the creditor window closes: If you distribute assets to heirs before the four-month creditor claim period expires and a valid creditor then files a claim, you are personally obligated to reimburse the estate. The heirs received their money; you absorb the creditor's valid claim out of pocket.
Paying debts in the wrong order: The family allowance ($30,000) and personal property allowance ($15,000) are priority claims that supersede general creditors. If you pay Visa before you fund the family allowance, the surviving spouse can sue you for the difference — and win.
Missing the Medicaid reporting window: The 10-day window to notify the Income Support Division is an administrative rule that many executors learn about only after the deadline has passed. Missing it complicates the recovery process but does not eliminate the HCA's claim.
Treating community property as the decedent's estate: In New Mexico, the surviving spouse owns one-half of all community property acquired during the marriage. That half never enters the probate estate. Inventorying it as a probate asset and distributing it can constitute conversion — taking property that belongs to someone else.
Frequently Asked Questions
How much does it cost to handle New Mexico probate without a lawyer?
Fixed costs regardless of whether you use an attorney:
- Court filing fee: $30 (county probate court, informal proceedings)
- Death certificates: $5.00 per copy from NMDOH (order 10-15 upfront)
- Newspaper publication for creditor notice: $150-$400 depending on the county and newspaper
- Deed recording fees: $25 base plus per-page equipment fees at the county clerk
- OMI cremation permit: $230 if applicable
Professional fees you avoid by handling it yourself: attorney fees of $4,000-$15,000. Plus any national platform subscription fees ($175-$499).
Can I handle New Mexico probate from out of state?
Yes. Many New Mexico estates are administered by adult children who live in other states. The county probate court accepts mailed filings. You will need to make one trip to the county to file in person if required locally, or confirm whether the court accepts filings by mail. The Letters you receive are recognized by financial institutions, agencies, and the MVD regardless of where you are located. The ancillary consideration: if you are the executor from another state and the decedent owned New Mexico property while living elsewhere, you may need to file a Proof of Authority under NMSA § 45-4-201 rather than opening a full New Mexico probate.
Do I need to file a tax return for the estate?
Yes. The estate requires a federal fiduciary income tax return (Form 1041) for any year it earns more than $600 in income. The decedent's final federal income tax return (Form 1040) is due for the year of death. New Mexico does not have a state estate tax or inheritance tax, but a New Mexico fiduciary income return may be required if the estate has New Mexico-source income. If the decedent owned a business subject to Gross Receipts Tax, request a Tax Clearance from the Taxation and Revenue Department before distributing business assets.
What if the only asset is the family home and it is in both spouses' names?
If the home is held in joint tenancy with right of survivorship, it passes automatically to the surviving spouse and is not a probate asset at all — file an affidavit of survivorship with the county clerk and record it. If the home is held as community property in both names, the surviving spouse may qualify for the Homestead Affidavit Transfer under NMSA § 45-3-1205 after six months, bypassing probate entirely. If neither of these applies, the property must go through the standard probate process.
How do I know if the decedent's property is community or separate?
New Mexico law presumes all property acquired during the marriage is community property. The burden of proof falls on whoever claims it is separate. Separate property is property acquired before the marriage, or received during the marriage as a personal gift or inheritance — but only if it was never commingled with marital funds. Bank records, deed records, and transfer documents are the evidence needed to establish separate property. If the records are incomplete or the property has been mixed with marital assets over a long marriage, characterization can be genuinely difficult — that is one situation where an attorney's opinion has value even in an otherwise simple estate.
