Overview

Doña Ana County is located in New Mexico with a population of approximately 220,000. The Doña Ana County Probate Court handles informal probate proceedings, while the Third Judicial District Court handles formal and contested estate matters for decedents who were domiciled in the county at the time of death.

New Mexico probate is governed by the Uniform Probate Code (NMSA 1978, Chapter 45). The process often begins with filing an Application for Informal Probate of Will and for Informal Appointment of Personal Representative (Form 4B-302) for testate estates or Application for Informal Appointment of Administrator (Form 4B-301) for intestate estates 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.

For smaller estates, New Mexico offers a simplified procedure using an Affidavit of Successor in Interest if the value of the estate (excluding liens and encumbrances) is $50,000 or less and the estate contains no real property.

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

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 (personal property only) and 30 days have passed since death, you may use an Affidavit of Successor in Interest to collect assets.
  • 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 Application

If probate is needed, file an Application for Informal Probate (Form 4B-302 for testate estates or Form 4B-301 for intestate estates) with the Doña Ana County Probate Court. Include:

  • Original Will (if one exists)
  • Certified Death Certificate
  • Application for Informal Appointment of Personal Representative
  • Filing fee ($30.00 for Probate Court)
  • Order of Informal Appointment and Letters Testamentary/Administration

Note: If the estate involves disputes or complex issues, you may need to file a Petition for Formal Probate with the District Court (filing fee approx. $132.00).

Step 3: Provide Notice

After appointment, you must:

  • Mail notice to all heirs, devisees, and known creditors within 30 days of appointment.
  • Publish notice to unknown creditors in a newspaper of general circulation in Doña Ana County (e.g., Las Cruces Sun-News) once a week for three successive weeks.

Step 4: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors: Creditors have two months from the date of first publication to file claims.
  • Inventory and appraise all estate assets within three months of appointment.
  • Pay valid creditor claims and administrative expenses.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • Close the estate by filing a Verified Statement of Personal Representative to close the estate informally.
