Overview

Luna County is located in New Mexico with a population of approximately 25,900. The Luna County Probate Court handles all informal probate and estate matters for decedents who were domiciled in the county at the time of death. Contested or formal matters are heard by the Sixth Judicial District Court.

New Mexico probate is governed by the Uniform Probate Code (Chapter 45). The process often begins with filing an Application for Informal Probate of Will and for Informal Appointment of Personal Representative (Form 4B-102) to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

New Mexico offers a simplified procedure for small estates. If the value of the estate, less liens and encumbrances, does not exceed $50,000, an Affidavit of Successor in Interest (Small Estate Affidavit) may be used to collect assets without formal probate, provided 30 days have elapsed since the death.

New Mexico does not have a statutory fee schedule for attorneys or personal representatives; fees must be reasonable based on the services provided.

This guide provides an informational overview of the Luna County probate process. It is not legal advice and is not a substitute for consulting a qualified attorney. Laws and local procedures may change — verify current requirements with the court.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Affidavit: If the estate is valued at $50,000 or less (less liens), you may use an Affidavit of Successor in Interest after a 30-day waiting period.
  • Transfer on Death: Real estate with a recorded Transfer on Death Deed or accounts with beneficiary designations bypass probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If probate is needed, file an Application for Informal Probate (Form 4B-102) or Petition for Formal Probate (Form 4B-101) with the Luna County Probate Court. Include:

  • Application or Petition signed and notarized
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee ($30.00 for informal probate)
  • Order of Appointment and Letters (proposed)

E-filing is generally not available for the Probate Court; documents are typically filed in person or by mail.

Step 3: Provide Notice

After filing (or upon appointment in informal proceedings), you must:

  • Mail notice to all heirs, beneficiaries, and interested parties within 10 days of appointment (informal) or at least 14 days before the hearing (formal).
  • Publish notice in a newspaper of general circulation in Luna County (such as the Deming Headlight) once a week for three successive weeks to notify creditors.

Step 4: Attend the Hearing

For formal probate, the court will schedule a hearing on the petition, typically 2 to 4 weeks after filing. At the hearing, the judge reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration. (Note: Informal probate typically does not require a hearing).

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and allow 2 months for claims to be filed
  • Inventory and appraise all estate assets within 3 months of appointment
  • Pay valid creditor claims
  • File federal and state tax returns as needed
  • Distribute assets to beneficiaries
  • File a Verified Statement of Personal Representative to close the estate
