New York Power of Attorney Laws: Durable, Medical, and Financial POA (2026)

New York is one of the few states where a power of attorney is durable by default. Under N.Y. Gen. Oblig. Law s. 5-1501A, a POA remains effective even if the principal later loses capacity, unless the document explicitly states otherwise. Sweeping 2021 reforms (Chapter 84, Laws of 2021, signed March 25, 2021) tightened execution requirements significantly: a valid New York POA now requires the principal's signature and notarization, the agent's signature and notarization, and two disinterested witnesses. The governing statute is the New York Statutory Short Form Power of Attorney, N.Y. Gen. Oblig. Law ss. 5-1501 through 5-1513. Medical decisions remain entirely separate: New York uses a Health Care Proxy under N.Y. Pub. Health Law ss. 2980-2994.

What a Power of Attorney Does in New York

A power of attorney is a written document in which a principal authorizes an agent (sometimes called an attorney-in-fact) to act on the principal's behalf in financial and legal matters. The agent's authority can be broad or narrow depending on the categories of power selected in the document.

New York law recognizes the Statutory Short Form POA under s. 5-1513, which organizes authority into 14 enumerated categories: real estate transactions, chattel and goods transactions, bond and commodity transactions, banking transactions, business operating transactions, insurance transactions, estate transactions, claims and litigation, personal and family maintenance, benefits from governmental programs, financial matters related to health care, retirement benefit transactions, tax matters, and all other matters. The principal selects which categories to grant.

An agent acting under a New York POA is a fiduciary under s. 5-1505. That means the agent must act in the principal's best interest, avoid conflicts of interest, keep the principal's assets separate from personal funds, and maintain detailed records of all transactions. The agent must make records and a copy of the POA available within 15 days of a written request from a monitor, a co-agent or successor agent, a government entity investigating potential abuse, a court evaluator, a guardian ad litem, a conservator of the principal's estate, or the personal representative of a deceased principal's estate.

A New York POA ends at the principal's death. After death, the agent has no further authority and the executor or administrator of the estate takes over.

Durable by Default: New York's 2021 Power of Attorney Reforms

Under N.Y. Gen. Oblig. Law s. 5-1501A, a power of attorney in New York is durable unless the document expressly provides that it terminates upon the principal's incapacity. This default rule is significant: most states require affirmative "durable" language, but New York flips that presumption.

The 2021 reforms, enacted through Assembly Bill A2353 (Chapter 84, Laws of 2021) and signed by the Governor on March 25, 2021, made several major structural changes to New York POA law:

The agent must also sign. Before 2021, only the principal needed to sign and acknowledge a New York POA. The 2021 law added a requirement that the agent sign and date the document, with the agent's signature acknowledged in the same manner as a conveyance of real property. The POA does not become effective until the agent's acknowledgment is complete. For co-agents, all named agents must sign before the document is effective.

Two witnesses are now required. The principal's signing must be witnessed by two people who are not named as agents or permissible gift recipients under the instrument. The person who takes the acknowledgment (the notary) may serve as one of the two witnesses.

The Statutory Gifts Rider was eliminated. Before 2021, gifting authority exceeding certain thresholds required a separate, separately signed Statutory Gifts Rider attached to the POA. The 2021 reform abolished that rider. Gifting authority over $5,000 per year is now handled entirely within the Modifications section of the main POA document, described in detail in the next section.

Substantial compliance standard adopted. Minor, insubstantial variations in the required caution and information language do not invalidate the POA as a statutory short form document.

Third-party refusal penalties strengthened. The 2021 amendments reinforced the prohibition on unreasonable third-party refusals and clarified that acceptance deadlines apply to both financial institutions and other third parties (with a carve-out for Medicaid administration).

How to Create a Valid New York Power of Attorney

N.Y. Gen. Oblig. Law s. 5-1501B sets out every requirement for a valid New York statutory short form POA. All of the following must be satisfied:

1. Typed or printed, minimum 12-point type. The document must be legible, typed or printed in at least 12-point size. Handwritten documents must use a reasonably equivalent readable format.

2. The principal signs, initials, and dates. The principal must sign, initial, and date the document. The signature must be acknowledged before a notary in the same manner as a conveyance of real property. If the principal is physically unable to sign, another person (not the agent) may sign at the principal's direction and in the principal's presence.

3. Two disinterested witnesses. Two witnesses must be present when the principal signs. Neither witness may be named as an agent under the document or as a permissible recipient of gifts. The notary taking the acknowledgment may serve as one of the two witnesses.

4. The agent signs and acknowledges. Any agent named in the document who will act must also sign and date the document, with the signature acknowledged before a notary in the same manner as a conveyance of real property. The POA is not effective until this step is complete. If multiple co-agents are named, all must sign before effectiveness is established.

5. Required caution language included. The document must contain substantially the "Caution to the Principal" and "Important Information for the Agent" language prescribed by s. 5-1513. Minor wording variations do not invalidate the form.

Out-of-state POAs are recognized in New York if they were properly executed under the law of the state where they were created, under s. 5-1512.

What a New York Agent Can and Cannot Do

Enumerated Powers and the Modifications Section

The New York Statutory Short Form POA under s. 5-1513 grants authority only for the categories the principal selects. Each category is defined in detail in ss. 5-1502A through 5-1502N.

The principal may also use the Modifications section under s. 5-1503 to eliminate specific powers within a category, add supplementary powers, or include additional provisions not inconsistent with the statute, such as revoking a prior POA.

Gifting Authority and the $5,000 Annual Limit

Under s. 5-1502I, when a principal grants authority over personal and family maintenance, the agent may continue gifts the principal customarily made before the POA was created, up to a total of $5,000 per calendar year across all recipients and charitable donations combined.

To authorize the agent to make gifts exceeding $5,000 per year, the principal must expressly grant that expanded authority in the Modifications section of the POA form. This was the core change that replaced the old Statutory Gifts Rider. Any gift-making authority above $5,000 must be spelled out in writing in the Modifications section; it cannot be implied from the selection of a category alone.

Agent Duties and Prohibited Self-Dealing

As a fiduciary under s. 5-1505, the agent must:

• Follow the principal's instructions and act in the principal's best interest.
• Keep the principal's assets completely separate from personal funds.
• Maintain records of all receipts, disbursements, and transactions.
• Provide a full accounting within 15 days of a written request from the principal, a monitor, a co-agent, or other authorized parties.

Self-dealing is prohibited. An agent cannot make gifts of the principal's property to themselves without explicit authorization in the document.

Third-Party Refusal Penalties

N.Y. Gen. Oblig. Law s. 5-1504 requires third parties to honor a properly executed and acknowledged New York POA. A third party who unreasonably refuses to accept a valid POA may be ordered by a court to pay damages, reasonable attorney fees, and litigation costs. Refusal based solely on the POA not being on a third party's proprietary form, the time elapsed since execution, or the gap between the principal's and agent's acknowledgment dates is specifically identified as unreasonable. Third parties must honor or reject the POA within ten business days of presentation.

Health Care Proxy in New York

New York law keeps financial and medical authority in completely separate documents. A financial POA under ss. 5-1501 to 5-1513 does not authorize the agent to make health care decisions.

Medical decision-making in New York is governed by the Health Care Proxy statute: N.Y. Pub. Health Law ss. 2980 through 2994. A Health Care Proxy is a written document in which a competent adult (the principal) appoints a health care agent to make any and all medical decisions on the principal's behalf if the principal loses the capacity to make those decisions personally.

Scope of the Health Care Agent's Authority

Under N.Y. Pub. Health Law s. 2982, the health care agent may make any health care decision the principal could make, including decisions about life-sustaining treatment, subject to any limitations the principal expresses in the proxy document. The agent must base decisions on the principal's known wishes, including religious and moral beliefs, or on the principal's best interests if wishes are unknown. The agent has the right to access all medical records needed to make informed decisions.

One important limitation: if the principal's preferences about artificial nutrition and hydration are unknown, the agent does not automatically have authority to withhold those measures. That authority must be addressed expressly in the proxy.

When the Health Care Proxy Takes Effect

Under N.Y. Pub. Health Law s. 2983, the health care proxy does not become effective until the principal's attending practitioner determines, to a reasonable degree of medical certainty, that the principal lacks the capacity to make health care decisions. That determination must be documented in writing. For decisions involving life-sustaining treatment, a second physician, physician assistant, or nurse practitioner must also confirm the incapacity.

If the principal regains capacity, the agent's authority ceases immediately. If the principal objects to the incapacity determination or to the agent's decision, the principal's objection controls unless a court finds actual incapacity.

How to Execute a Health Care Proxy

Under N.Y. Pub. Health Law s. 2981, a valid New York Health Care Proxy must be:

• Signed and dated by the principal.
• Witnessed by two adults who also sign the document.
• The appointed health care agent cannot serve as a witness.

The notarization requirement that applies to the financial POA does not apply to the Health Care Proxy. The two-witness rule is the key execution requirement. For principals residing in mental health or developmental disabilities facilities, additional witness qualifications apply.

If a person in New York wants both financial and medical authority covered, two separate documents are needed: a Statutory Short Form Power of Attorney for finances and a Health Care Proxy for medical matters.

Revoking or Ending a New York Power of Attorney

A principal may revoke a New York POA at any time while they retain capacity. Under N.Y. Gen. Oblig. Law s. 5-1511, revocation may be accomplished by:

• Revoking in accordance with the terms stated in the POA itself, or
• Delivering a written revocation to the agent by hand, mail, courier, electronic transmission, or fax to the agent's last known address.

If the original POA was recorded with the county clerk (as is often done for real property transactions), the written revocation must also be recorded in the same office.

When revocation takes effect against the agent: A revocation is effective against the agent once the agent actually receives it.

When revocation takes effect against third parties: For third parties other than financial institutions, revocation does not bind them until they receive actual written notice. Financial institutions are deemed to have received notice after written revocation is delivered to the branch where the account is held and the institution has had a reasonable opportunity to act.

Any third-party transactions carried out in good faith before receiving notice of revocation remain valid and binding on the principal.

A New York POA also ends automatically upon the principal's death. After death, the agent's authority ceases entirely. A POA that is not durable also ends automatically if the principal loses capacity.
