New Mexico: Power of Attorney Requirements

The short answer

New Mexico adopted the Uniform Power of Attorney Act in 2007, codified at
NMSA 1978 §§ 45-5B-101 to 45-5B-403 within the Uniform Probate Code (recompiled
into its current section numbers in 2011). Under § 45-5B-105, a financial
power of attorney (POA) must be "signed by the principal or in the principal's
conscious presence by another individual directed by the principal to sign the
principal's name." Notarizing that signature is not required for the document
to be valid, but it matters in practice: an acknowledged signature "is
presumed to be genuine" (§ 45-5B-105), and a POA used to convey real estate
must be acknowledged, certified, and recorded (NMSA § 47-1-7). A New Mexico
POA is durable by default — it survives your later incapacity — unless the
document says otherwise (§ 45-5B-104).

Requirements one by one

Governing law

Financial powers of attorney are governed by the Uniform Power of Attorney
Act, NMSA 1978 §§ 45-5B-101 to 45-5B-403, enacted by Laws 2007, ch. 135 and
recompiled into Article 5B of the Uniform Probate Code by Laws 2011, ch. 124.
Health care powers of attorney are addressed separately under the Uniform
Health-Care Decisions Act and are outside this survey's scope.

Who must sign

The principal signs the POA. If the principal is physically unable to sign,
another adult may sign the principal's name instead, but only "in the
principal's conscious presence" and at the principal's direction
(§ 45-5B-105). The statute does not require the document to be dated.

Notarization

Not mandatory. Signing alone makes the POA valid; if the principal instead
"acknowledges the signature before a notary public or other individual
authorized by law to take acknowledgments," that acknowledged signature "is
presumed to be genuine" (§ 45-5B-105) — a rebuttable evidentiary boost, not a
validity requirement. Notarization becomes practically necessary whenever the
POA will be used to convey real estate, since recording requires it (see
Real estate extras).

Witnesses

None required by statute. Section 45-5B-105 — New Mexico's complete execution
section for a financial POA — says nothing about witnesses.

Statutory form

Yes, but optional. New Mexico publishes a fill-in-the-blank "Statutory Form
Power of Attorney" at § 45-5B-301: "A document substantially in the following
form may be used to create a statutory form power of attorney that has the
meaning and effect prescribed by the Uniform Power of Attorney Act." You are
not required to use it — any document meeting § 45-5B-105 works — but banks
and title companies recognize it on sight. The New Mexico Supreme Court Law
Library posts a fillable version of the form.

Durable by default?

Yes. Under § 45-5B-104, a New Mexico POA "is durable unless it expressly
provides that it is terminated by the incapacity of the principal." You have
to opt out of durability, not into it.

Springing POA allowed?

Yes. A POA "is effective when executed unless the principal provides in the
power of attorney that it becomes effective at a future date or upon the
occurrence of a future event or contingency" (§ 45-5B-109(A)) — typically the
principal's incapacity. The principal may name one or more people to determine
in writing that the triggering event happened (§ 45-5B-109(B)). If no one is
named, or the named person is unwilling or unable to decide, a physician or
licensed psychologist (for an inability to receive and evaluate information),
or an attorney at law, judge, or appropriate government official (for a
principal who is missing, detained, or unable to return to the United
States), makes that determination instead (§ 45-5B-109(C)).

Real estate extras

Any POA "containing authority to convey real estate ... or by which real
estate may be affected in law, or equity, shall be acknowledged, certified,
filed and recorded, as other writings conveying or affecting real estate are
required to be acknowledged" (NMSA § 47-1-7). Once recorded, the POA cannot be
treated as revoked as to anyone relying on the record until the revocation
itself is acknowledged, certified, and recorded in the same county clerk's
office.

Out-of-state POAs

Yes. A POA "executed other than in this state is valid in this state" if its
execution complied with the law of the jurisdiction that governs the POA's
meaning and effect, or with the federal military power-of-attorney statute,
10 U.S.C. § 1044b (§ 45-5B-106(C)). New Mexico determines which jurisdiction's
law governs meaning and effect by looking at what the POA itself specifies, or
absent that, the state where it was executed (§ 45-5B-107).

What trips people up

• No witnesses, but recording still needs acknowledgment. A POA signed
  without a notary is fully valid for everyday banking use, but it cannot be
  recorded for a real estate transaction without one (NMSA § 47-1-7).
• Springing POAs need a determination mechanism. If you make your POA
  effective only upon incapacity and don't name someone to certify that in
  writing, a physician, psychologist, attorney, judge, or government official
  becomes the trigger instead (§ 45-5B-109(C)) — which can add delay exactly
  when speed matters.
• A handful of powers need express, specific wording. New Mexico's general
  authority provisions do not, by themselves, let an agent make gifts, change
  survivorship rights or beneficiary designations, or create, amend, or revoke
  a trust — those require the POA to grant that specific authority.
• Durability is the default — read the document carefully if you don't want
  it. Because § 45-5B-104 makes durability automatic, a POA that is meant to
  end at incapacity must say so explicitly.

Common questions

Do I need to get my New Mexico power of attorney notarized? Not for basic
validity — a signature alone satisfies § 45-5B-105. Get one notarized anyway
if real estate might be involved, since recording a POA that conveys property
requires it to be acknowledged (NMSA § 47-1-7).

Does my New Mexico POA need witnesses? No. New Mexico's financial-POA
statute imposes no witness requirement.

Will an out-of-state power of attorney work in New Mexico? Yes, if it was
validly executed under the law that governs its meaning and effect (usually
the state named in the document, or the state of execution) — § 45-5B-106(C).

Can I make my POA effective only if I become incapacitated? Yes, that's a
springing POA under § 45-5B-109. Name someone in the document to certify the
incapacity in writing; otherwise a physician, licensed psychologist, attorney,
judge, or government official makes that call instead.
