New York: Power of Attorney Requirements

The short answer

New York's execution rules live in General Obligations Law § 5-1501B, which
was substantially rewritten effective June 13, 2021. To be valid, a power of
attorney (POA) executed in New York must be typed or printed in at least
12-point type; be signed, initialed, and dated by a principal with capacity;
have the principal's signature acknowledged before a notary the way a deed
is; and be witnessed by two people who are not named in the document as
agents or as permissible recipients of gifts. The notary may double as one of
the two witnesses.

Two features stand out against other states. The agent must also sign, with
their signature acknowledged, and the POA takes effect as to each agent only
when that agent's signature is acknowledged. And a New York POA is durable by
default — it keeps working through the principal's incapacity unless the
document expressly says otherwise.

Requirements one by one

Governing law

Financial POAs are governed by Article 5, Title 15 of the General Obligations
Law (§§ 5-1501 through 5-1514). New York has not adopted the Uniform Power of
Attorney Act; this is the state's own statutory scheme, and its current
execution rules date from the overhaul that took effect June 13, 2021
(§ 5-1501B(5)(a) preserves documents "executed by a principal in the manner
conforming with the law in effect at the time," including older statutory
gift riders).

Who must sign

Three signatures matter. The principal must sign, initial, and date the
document — "a principal with capacity," which the statute defines as the
"ability to comprehend the nature and consequences of the act of executing
and granting ... a power of attorney" (§ 5-1501(2)(c)). If the principal is
physically unable, another person — anyone except a named agent or successor
agent — may sign the principal's name in the principal's presence and at the
principal's direction (§ 5-1501B(1)(b)). And each agent must sign and date
the document too, with an acknowledged signature, before acting
(§ 5-1501B(1)(c)); a gap in time between the principal's and agent's
signatures does not invalidate the POA, even if the principal became
incapacitated in the meantime.

Notarization

Required. The principal's signature (or the substitute signer's) must be
"duly acknowledged in the manner prescribed for the acknowledgment of a
conveyance of real property" — a notarial acknowledgment — and the agent's
signature must be acknowledged the same way (§ 5-1501B(1)(b)–(c)).

Witnesses

Two witnesses must sign in the presence of the principal, and neither may be
"named in the instrument as agents or as permissible recipients of gifts"
(§ 5-1501B(1)(b)). To save a trip, the statute lets the notary who takes the
acknowledgment "also serve as one of the witnesses."

Statutory form

Yes. Section 5-1513 sets out the New York Statutory Short Form Power of
Attorney; using it "or one which substantially conforms" is lawful, and
optional sections may be omitted if replaced with the words "Intentionally
Omitted." Even a custom (non-statutory) POA must substantially conform to two
blocks of § 5-1513 wording: the "Caution to the Principal" and the "Important
Information for the Agent" (§ 5-1501B(1)(d)). Insubstantial wording
variations are forgiven (§ 5-1501B(2)) — a 2021 change from the prior
exact-wording regime.

Durable by default?

Yes. "A power of attorney is durable unless it expressly provides that it is
terminated by the incapacity of the principal" (§ 5-1501A(1)). This is the
reverse of most large states: in New York you must opt out of durability, not
into it.

Springing POA allowed?

Yes. A POA may state that it "takes effect upon the occurrence of a date or a
contingency specified in the document" (§ 5-1501B(3)(b)) — for example, a
determination of incapacity. If the document names a person to declare in
writing that the contingency has occurred, that declaration is enough to make
the POA effective, "without regard to whether the specified contingency has
occurred," which protects banks and others who rely on it. Remember
that the POA is never effective as to an agent until that agent's signature
has been acknowledged (§ 5-1501B(3)(a)).

Real estate extras

Nothing extra is required at signing — every New York POA is already
acknowledged in deed fashion. For land transactions, "an instrument
containing a power to convey real property, as the agent or attorney for the
owner of the property, acknowledged or proved, and certified, in the manner
to entitle a conveyance to be recorded, may be recorded" with the county
recording officer (Real Prop. Law § 294(1)). Recording the POA is permissive
under the statute; in practice the county clerk records it with the deed the
agent signs.

Out-of-state POAs

Recognized broadly. A POA "executed in another state or jurisdiction in
compliance with the law of that state or jurisdiction or the law of this
state is valid in this state, regardless of whether the principal is a
domiciliary of this state" (§ 5-1512). The same section validates New York
POAs signed elsewhere by New York domiciliaries.

What trips people up

• The agent's signature is part of execution. The POA is effective as to
  an agent only when that agent has signed with an acknowledged signature
  (§ 5-1501B(1)(c), (3)(a)). An unsigned agent has no authority, and co-agents
  required to act together must all have signed.
• Wrong witnesses. A person named in the document as an agent or as a
  permissible gift recipient cannot be a witness (§ 5-1501B(1)(b)). Family
  members who will receive gifts under the POA are the classic mistake.
• Type size counts. The statute requires letters "no less than twelve
  point in size" (§ 5-1501B(1)(a)). A shrunken photocopy-of-a-form can flunk
  a formality.
• Missing the statutory wording. Even a lawyer-drafted custom POA must
  substantially conform to the § 5-1513 "Caution to the Principal" and
  "Important Information for the Agent" text (§ 5-1501B(1)(d)).
• Assuming old documents died in 2021. They did not: POAs and statutory
  gift riders executed in conformity with the law in effect at the time
  remain valid (§ 5-1501B(5)(a)).

Common questions

Do I need witnesses and a notary? Yes — two witnesses plus an
acknowledgment before a notary, though the notary may count as one of the two
witnesses (§ 5-1501B(1)(b)), so in practice you need the notary plus one more
person.

Is my New York power of attorney durable? Yes, unless the document
expressly says it terminates on your incapacity (§ 5-1501A(1)). No special
durability wording is needed.

Can it take effect only if I become incapacitated? Yes. State the
contingency in the document, and consider naming a person whose written
declaration establishes that the contingency occurred — the statute makes
that declaration sufficient for third parties (§ 5-1501B(3)(b)).

Will an out-of-state power of attorney work in New York? Yes, if it was
executed in compliance with that jurisdiction's law or New York law
(§ 5-1512).
