Probate in New Mexico uses reasonable compensation for attorney fees, typically 1.8-2.9% of the estate value — about $25,612 all-in on a $500,000 estate. Estates under $50,000 may qualify for Small Estate Affidavit.

Simple estates in New Mexico typically take 4-6 months through probate. Complex or contested estates can take 1-3 years. A revocable trust avoids probate entirely.

New Mexico has adopted the Uniform Trust Code and does not require witnesses for trust execution. Notarization is not required for validity, though many financial institutions require notarized trust documents. New Mexico has no separate trust creditor-notice step — the settlor's debts stay subject to the general claims and limitations period (up to 12 months), which the trustee settles before distributing.

New Mexico offers remote online notarization (RON) for estate planning documents and transfer-on-death deeds to pass real estate without probate. These tools, combined with revocable trusts and beneficiary designations, provide multiple ways to transfer assets without probate.

A healthcare power of attorney in New Mexico requires no witnesses or notarization to be valid. A financial power of attorney requires no witnesses or notarization. A financial power of attorney is durable by default, so it stays in effect if you become incapacitated.

In New Mexico, the executor must file an inventory of the estate's assets within 90 days of appointment. A revocable trust skips the court-supervised inventory entirely, so a trustee distributes assets without filing one.

In New Mexico, divorce automatically revokes a beneficiary designation that names a former spouse on covered accounts, so the asset does not pass to the ex-spouse unless the designation is renewed after the divorce.

The Small Estate Affidavit is presented directly to the bank, employer, or other holder of the property — it is not filed with a court.

Notarization isn't required for validity, though banks and title companies typically expect a notarized trust before they'll work with it.
