Frequently Asked Questions

You open probate by filing a petition with the Doña Ana County Probate Court in Doña Ana County, attaching the original will (if any), the death certificate, and the filing fee ($132). Once the court issues letters, the personal representative can act.

At minimum: petition for probate, application for letters testamentary or of administration, notice to heirs, and an oath for the personal representative. Doña Ana County uses the standard New Mexico probate forms — the court's website lists the current versions.

New Mexico allows informal (unsupervised) probate, which many families handle themselves for simple estates. The Doña Ana County Probate Court in Doña Ana County does not require attorney representation. Use the New Mexico self-filing assessment to see if your estate qualifies.

Doña Ana County typically requires in-person or mail filing for probate petitions. Check the court's website for the latest procedures — some counties have added e-filing for specific document types.

Assets stay locked, creditors can still pursue them, and beneficiaries cannot sell real property or close accounts. After a few years, interested parties can petition to open probate themselves. Waiting rarely helps. Families who set up a revocable living trust ahead of time bypass this problem entirely.
