The New York Health Care Proxy: A Fiduciary-Grade Guide to Appointing the Right Medical Agent (2026)

A health care proxy is the most personal document in your estate plan. Your will directs property; your power of attorney directs money. The health care proxy decides who speaks for your body when you cannot speak for yourself. Under New York Public Health Law Article 29-C, this single instrument lets you appoint an agent to make medical decisions on your behalf — from routine consent to the most consequential end-of-life choices — the moment a physician determines you lack capacity.

At Morgan Legal Group, we treat the proxy not as a form to be filled in, but as a fiduciary appointment to be engineered. Choosing an agent is the act of handing another person legal authority over your treatment, your privacy, and, in defined circumstances, your survival. That authority demands the same rigor we apply to any fiduciary role. This page explains the proxy under New York law statewide — for clients in New York City, on Long Island, in Westchester, the Hudson Valley, and Upstate — and shows how to get it right.

What a Health Care Proxy Actually Does

A New York health care proxy is governed by Public Health Law Article 29-C. It authorizes a competent adult (you, the principal) to appoint another adult (your agent) to make health care decisions if and when your attending physician determines, to a reasonable degree of medical certainty, that you have lost the capacity to make those decisions yourself. Until that determination is made, you remain fully in charge of your own care. The proxy does not surrender your autonomy; it preserves it by guaranteeing that the person who steps in is the person you chose.

Two features make the proxy uniquely powerful:

• Broad scope. Once it takes effect, your agent generally has the same authority to consent to or refuse treatment that you would have had, including decisions about surgery, medication, life-sustaining treatment, and the choice of providers and facilities.
• Continuity. Unlike informal arrangements, the proxy follows you across hospitals, nursing homes, and home care, and it overrides the default “next of kin” hierarchy that would otherwise apply.

The Proxy Is Not the Power of Attorney

A frequent and costly misconception is that one document covers everything. It does not. New York deliberately separates the two authorities:

Document	Governing Law	Decisions Covered	Agent Title
Health Care Proxy	Public Health Law Article 29-C	Medical and personal-care decisions	Health care agent
Durable Power of Attorney	General Obligations Law §5-1513	Financial, legal, and property matters	Agent (attorney-in-fact)

Your financial agent under a GOL §5-1513 durable power of attorney cannot consent to your surgery, and your health care agent cannot pay your bills or manage your accounts. A complete plan requires both, drafted to work in tandem. (See our Power of Attorney page for the financial side.)

The Fiduciary Standard: How Your Agent Must Decide

This is where a professionally drafted plan separates itself from a downloaded form. A health care agent is not free to substitute personal preference. New York law imposes a two-tier decision standard, and a well-counseled client documents the inputs that make that standard work.

1. Known wishes first. The agent must make decisions in accordance with your wishes, including your religious and moral beliefs — wishes that the agent must know. This is why a proxy that simply names a person, with nothing more, leaves your agent dangerously underequipped.
2. Best interests second. Where your wishes are not reasonably known and cannot with reasonable diligence be ascertained, the agent must act in your best interests.

There is a critical statutory carve-out: decisions about artificial nutrition and hydration require that your agent has reasonable knowledge of your wishes on that specific subject. If your proxy is silent and you have never discussed it, your agent may lack authority to make that very decision. A fiduciary-grade proxy anticipates this gap and closes it — through clear written instructions and a recorded conversation with your agent — so the person you trust is never paralyzed at the worst possible moment.

Choosing and Safeguarding Your Agent

Selecting an agent is a fiduciary-selection exercise. We counsel clients to weigh three qualities:

• Availability. Will this person realistically be reachable and able to come to a hospital? Geography matters less than reliability, but both count.
• Resolve. Can this person honor your wishes under pressure from other family members, even when those wishes are difficult? An agent who cannot hold the line is the wrong agent.
• Judgment. Where you are silent, the agent must reason toward your best interests. Choose someone whose temperament and values you trust.

Build in Safeguards

A robust proxy includes structural protections:

• A successor (alternate) agent. If your primary agent is unavailable, unwilling, or unable to serve, a named alternate prevents a vacuum. Without one, your proxy can fail precisely when needed.
• No competing co-agents. New York does not permit two agents to serve simultaneously under one proxy. Naming a primary and a successor — not two equals — avoids deadlock.
• HIPAA authorization. A proxy that also authorizes the release of medical information lets your agent obtain the records they need to decide responsibly.
• Specific instructions where it counts. Guidance on life-sustaining treatment, artificial nutrition and hydration, and pain management converts your agent from a guesser into a faithful executor of your will.

Witnessing and Execution

To be valid under Article 29-C, a New York health care proxy must be signed and dated by you (or, if you are unable, by another adult at your direction and in your presence) in the presence of two adult witnesses. The person you name as your agent or alternate agent cannot serve as a witness. Each witness attests that you appeared to act willingly and free from duress. No notarization is required, and there is no filing. We counsel clients to distribute copies to the agent, the alternate, and their treating physicians, and to keep the proxy accessible — a perfect proxy in a locked drawer helps no one.

Where the Proxy Fits in Your Estate Plan

A comprehensive New York estate plan is not a stack of separate documents; it is a coordinated system of four instruments:

• A Will — EPTL §3-2.1 — directs your property and names guardians and an executor. Dying without one (intestacy) is governed by EPTL Article 4, and the state, not you, decides who inherits. (See Wills.)
• Trusts — EPTL Article 7 — a revocable living trust avoids probate (though it provides no estate-tax savings), while an irrevocable trust is used for tax reduction, asset protection, and Medicaid planning subject to the five-year look-back; a supplemental needs trust under EPTL 7-1.12 preserves public benefits. (See Trusts.)
• A durable Power of Attorney — GOL §5-1513 — handles your finances during incapacity. (See Power of Attorney.)
• A Health Care Proxy — Public Health Law Article 29-C — handles your medical decisions.

The proxy is the only one of the four that operates entirely while you are alive and incapacitated. Coordinated drafting ensures your health care agent and your financial agent — who may or may not be the same person — are not working at cross-purposes, and that funding for care under an irrevocable trust does not collide with the consent decisions your medical agent must make.

A Note on the New York Estate Tax (2026)

The proxy itself has no tax consequence, but it shares a plan with documents that do. For 2026, the New York basic exclusion amount is $7,350,000 for deaths on or after January 1, 2026, through December 31, 2026. New York imposes a punishing “cliff”: an estate exceeding 105% of the exclusion — $7,717,500 — loses the entire exemption and is taxed from the first dollar, at progressive rates of 3% to 16%. New York has no gift tax, but gifts made within three years of death are added back to the taxable estate. Clients whose estates approach the cliff should coordinate lifetime planning with their proxy and powers of attorney so that incapacity decisions do not inadvertently undo tax strategy. See our New York Estate Tax Guide.

A Professional Process, Not a Form

The difference between a valid proxy and an effective one is preparation. Our process is built to produce the latter: we identify and vet your agent and alternate; we capture your specific wishes on life-sustaining treatment and artificial nutrition and hydration; we execute with proper witnesses; we add HIPAA authority; and we integrate the proxy with your will, trusts, and power of attorney so the whole plan moves as one. A form gives you a piece of paper. A fiduciary-grade engagement gives you certainty that the right person will act with the right authority for the right reasons.

Frequently Asked Questions

Is a New York health care proxy the same as a living will?
No. The health care proxy under Public Health Law Article 29-C appoints a person to decide for you. A living will is a written statement of your wishes. New York courts recognize living wills as evidence of intent, but they do not replace the proxy. The strongest approach pairs a proxy (who decides) with documented instructions (what they should decide), so your agent has clear guidance to follow.

Can my health care agent also be my power of attorney?
Yes — the same trusted person can serve in both roles, but it requires two separate documents. The health care proxy under Article 29-C governs medical decisions; the durable power of attorney under GOL §5-1513 governs financial and legal matters. One document cannot do both, and naming the same person without executing both instruments leaves a gap.

What happens if I do not have a health care proxy in New York?
If you lose capacity without a proxy, New York’s Family Health Care Decisions Act controls, and a surrogate is selected from a statutory priority list — which may not be the person you would have chosen and can produce conflict among family members. Executing a proxy lets you, not a default list, decide who speaks for you.

Can I change or revoke my health care proxy?
Yes. As long as you have capacity, you may revoke or replace your proxy at any time — by signing a new one, by notifying your agent or a health care provider, or by any act clearly showing your intent to revoke. Because a later proxy generally supersedes an earlier one, we recommend dating each version and distributing the current copy to your agents and physicians.

Must my agent follow my wishes about artificial nutrition and hydration?
Your agent may make decisions about artificial nutrition and hydration only if they have reasonable knowledge of your wishes on that subject. This is a specific statutory requirement under Article 29-C. If you never address it, your agent may lack authority to decide. That is why we counsel clients to state these wishes explicitly and to discuss them directly with the agent.
