Overview

San Miguel County is located in New Mexico with a population of approximately 27,200. The San Miguel County Probate Court handles informal probate matters for decedents who were domiciled in the county at the time of death. Formal and contested matters are heard by the Fourth Judicial District Court.

New Mexico probate is governed by the Uniform Probate Code (NMSA Chapter 45). The process often begins with filing an Application for Informal Probate and Appointment of Personal Representative (Form 4B-101) 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, successors may use a Small Estate Affidavit to collect personal property without full probate administration. There is also a summary administration process for surviving spouses.

Personal representatives are entitled to reasonable compensation for their services. Attorneys are also entitled to reasonable fees, which are not set by a statutory percentage but must be reasonable based on the work performed.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Affidavit: If the estate consists of personal property valued at $50,000 or less, you may be able to use an affidavit to collect assets 30 days after death.
  • Transfer on Death: Assets with named beneficiaries (POD/TOD accounts, life insurance) or held in joint tenancy bypass probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Application

If probate is needed, file an Application for Informal Probate and Appointment of Personal Representative with the San Miguel County Probate Court. Include:

  • Original Will (if any)
  • Certified Death Certificate
  • Application for Informal Probate (Form 4B-101)
  • Order of Informal Probate (Form 4B-102)
  • Acceptance of Appointment (Form 4B-105)
  • Letters Testamentary or Administration (Form 4B-107)
  • Filing fee (typically $30.00)

E-filing may be available for District Court cases, but Probate Court filings are often done in person or by mail.

Step 3: Provide Notice

After appointment, you must:

  • Mail notice (Form 4B-201) to all heirs, devisees, and interested parties within 30 days of appointment.
  • Publish notice to creditors in a newspaper of general circulation in San Miguel County (such as the Las Vegas Optic) once a week for three successive weeks.

Step 4: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify known creditors and allow 2 months (after publication) for claims.
  • Inventory and appraise all estate assets within 3 months of appointment.
  • Pay valid creditor claims and estate expenses.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.

Step 5: Close the Estate

Once administration is complete, file a Verified Statement of Personal Representative to Close Estate (Form 4B-501) to conclude the process.
