Power of Attorney Requirements in New Mexico

At a glance

Requirements one by one

Governing law

New Mexico calls §§ 45-5B-101 through 45-5B-403 the "Uniform Power of Attorney Act" (§ 45-5B-101). Section 45-5B-106(A) tests a New Mexico power signed on or after July 1, 2007 against its execution rule, § 45-5B-105.

Who must sign

Section 45-5B-105 requires the principal's signature, or a signature of the principal's name by "another individual" the principal directs to sign in the principal's conscious presence. The section supplies no age qualification for that directed signer.

Notarization

For an ordinary financial power, acknowledgment before a notary or another person authorized to take acknowledgments makes the principal's signature "presumed to be genuine" (§ 45-5B-105). It is not listed as a basic validity condition in § 45-5B-106(A). A power affecting real estate has the additional acknowledgment rule below.

Witnesses

Section 45-5B-105 states the complete execution rule: signature by the principal or a directed signer in conscious presence, and a presumption for an acknowledged signature. It names no witnesses.

Statutory form

New Mexico prints an optional form in § 45-5B-301. The statute says a document substantially in that form "may be used"; a different document can satisfy § 45-5B-105.

Durable by default?

Section 45-5B-104 says a power created under the Act "is durable unless it expressly provides that it is terminated by the incapacity of the principal." An express termination term reverses the default.

Springing POA allowed?

The principal can provide for effect at a future date or event (§ 45-5B-109(A)) and name someone to record that it occurred. If the trigger is incapacity and the named person cannot or will not act, subsection (C) allows a physician or licensed psychologist for one incapacity category, or an attorney, judge, or appropriate government official for the other.

Real estate extras

A power authorizing a conveyance of real estate, or otherwise affecting real estate, "shall be acknowledged, certified, filed and recorded" like other writings conveying or affecting real estate (NMSA § 47-1-7). This extra rule is separate from the ordinary financial power execution rule.

Out-of-state POAs

An out-of-state power is valid if its execution complied with the law of the jurisdiction determining its meaning and effect (§ 45-5B-106(C)). Under § 45-5B-107, that is the jurisdiction named in the document or, absent a choice, where it was executed. Section 45-5B-106(C) also recognizes a qualifying military power of attorney under 10 U.S.C. § 1044b.

What trips people up

• A recorded real estate power needs a recorded revocation. Once the power is recorded under § 47-1-7, that section says it is not considered revoked by the principal's act until an acknowledged, certified written revocation is filed and recorded in the same county clerk's office.

Common questions

Does a New Mexico power signed before July 2007 still count? Section 45-5B-106(B) tests its execution under the New Mexico law in effect when it was signed.

Can I present a scan? Section 45-5B-106(D) generally gives a photocopy or electronically transmitted copy the same effect as the original, unless another statute provides otherwise.
