New York Health Care Proxy: How to Appoint a Health Care Agent

Written by Albert Goodwin, Esq., a New York estate planning and probate attorney with offices serving Manhattan, Brooklyn, Queens, the Bronx, and Long Island. Last reviewed and updated: January 2025.

A New York health care proxy is one of the most important — and most frequently misunderstood — documents in an estate plan. In my practice, I see two recurring problems: clients who never sign one and leave their family scrambling during a crisis, and clients who signed one years ago that no longer reflects their wishes, names a deceased agent, or lacks the HIPAA language hospitals now expect. This page explains how the proxy works under New York law, the drafting mistakes I see most often, and how the proxy fits together with living wills, MOLST forms, and Article 81 guardianship.

If you want a broader overview of all advance planning tools, see our New York advance directive guide. This page focuses specifically on the health care proxy — choosing and empowering an agent to make medical decisions for you.

What a New York Health Care Proxy Actually Does

A health care proxy lets a competent adult (the "principal") appoint a trusted person (the "agent") to make health care decisions if the principal later loses the capacity to make those decisions personally. In other states this document is often called a "health care power of attorney." In New York, the proxy is governed by Article 29-C of the Public Health Law (§§ 2980–2994), and the standard form published by the New York State Department of Health is widely accepted by hospitals and providers across the state.

The proxy is narrow and powerful at the same time. It does not cover financial matters — that is the job of a financial power of attorney (a different document under the General Obligations Law). It covers only health care: consenting to or refusing treatment, choosing facilities, deciding about life-sustaining treatment, and similar medical questions.

Common decisions a New York agent may face include:

• Whether to start, continue, or stop life support during a coma or terminal condition
• Whether to provide or withhold artificial nutrition and hydration
• Choosing among treatment options or care facilities
• Decisions about organ and tissue donation, where authorized

Important New York wrinkle: an agent's authority to make decisions about artificial nutrition and hydration is limited unless the principal's wishes on that subject are reasonably known. For that reason, I strongly recommend that the proxy expressly state whether the agent knows your wishes on this point — otherwise providers may default to providing nutrition and hydration regardless of the agent's instructions.

Who Can — and Cannot — Serve as Your Agent

You can name almost any competent adult (18 or older) you trust:

• A spouse or domestic partner
• An adult child
• A parent or sibling
• A close friend
• Your attorney

You cannot name your attending physician as your agent, and operators or employees of a hospital, nursing home, or mental hygiene facility where you are a patient generally cannot serve unless they are related to you. New York permits you to name a successor agent who acts if your first choice is unavailable, unwilling, or unable to serve. You may name only one agent at a time to act — New York does not allow co-agents who act jointly, which is a frequent point of confusion. If you want a second person involved, name them as a successor, not a co-agent.

When the Agent's Authority "Springs" Into Effect

A health care proxy gives the agent no authority while you can still make your own decisions. The agent's authority becomes active only when the attending practitioner determines, to a reasonable degree of medical certainty, that you lack capacity to make health care decisions. Under Article 29-C, that determination must:

• Be made by the attending practitioner (the physician, or in some cases nurse practitioner or physician assistant, primarily responsible for your care)
• Be in writing and entered in your medical record
• State the cause, nature, and expected duration of the incapacity

For decisions to withhold or withdraw life-sustaining treatment, a second clinician must independently confirm the incapacity determination. This second-opinion safeguard exists precisely because these are irreversible decisions. If you regain capacity — even temporarily during a lucid interval — your own decisions control again, and the agent steps back.

The Standard Your Agent Must Follow

Your agent is not free to decide based on personal preference. The law requires the agent to follow your wishes if they are known, and only where your wishes are unknown to act in your best interests. Courts and providers look to:

• Specific instructions written into the proxy itself
• Other documents you signed (a living will, MOLST, or values statement)
• Statements you made to the agent or others about your preferences
• Your known religious or cultural values
• Your prior medical decisions in similar situations

This is why I tell clients that the proxy form alone is rarely enough. The most useful gift you can give your agent is a frank conversation about what matters to you, ideally backed up by written instructions, so the agent is never left guessing under pressure.

Drafting Mistakes I See Most Often in New York Proxies

Over years of preparing and reviewing these documents, certain errors come up again and again:

• No HIPAA authorization. Many older proxies give the agent authority to decide but no clear right to access medical records. Under federal HIPAA rules, an agent who cannot see the chart cannot make an informed decision. A properly drafted New York proxy includes HIPAA-release language naming the agent (and often others) as authorized to receive protected health information.
• Silence on artificial nutrition and hydration. As noted above, New York limits the agent's authority on this point unless your wishes are reasonably known. Leaving the form blank here can produce exactly the outcome a family hoped to avoid.
• Naming a single agent with no successor. If your one named agent predeceases you, moves away, or is unreachable, the proxy is effectively useless and your family falls back to the default surrogate rules.
• Trying to name co-agents. Because New York does not allow two agents acting together, attempts to do so create ambiguity that hospitals dislike.
• Witness defects. The proxy must be signed in the presence of two adult witnesses. A person you name as agent cannot serve as one of your witnesses. I have seen documents rejected for this reason.
• Stale documents after divorce. A divorce or legal separation automatically revokes the appointment of a former spouse as agent. If you intend a former spouse to keep serving, you must re-sign or add a written statement — and if you don't, you should make sure a new agent is named so there is no gap.

Practical Scenarios From a New York Estate Practice

Family disagreement. A validly appointed agent's decision is binding even when other relatives object. Disgruntled family members can petition a court, but New York courts generally defer to the named agent unless there is clear evidence the agent is ignoring the principal's known wishes or acting against their interests. A clearly drafted proxy with written instructions dramatically reduces the chance of a courtroom fight.

The adult child living out of state. Naming a child who lives across the country as your only agent can create real delays. I often suggest a local successor agent who can be physically present quickly in an emergency.

Religious and cultural directions. Clients with strong religious convictions — Catholic, Orthodox Jewish, Jehovah's Witness, and others — frequently want specific limits on treatment. New York lets you build these instructions into the proxy or a companion document so the agent is bound to honor them.

The temporarily lucid patient. Capacity can fluctuate. When a patient regains capacity during illness, their decisions override the agent's, which requires careful coordination with the treatment team. Documenting wishes in advance smooths these transitions.

How the Proxy Fits With Living Wills and MOLST

People often conflate these documents. They are not interchangeable:

• A health care proxy answers the question "who decides?"
• A living will answers the question "what do I want?" by stating treatment preferences in advance.
• A MOLST (Medical Orders for Life-Sustaining Treatment) converts those preferences into actual physician orders that follow you across care settings.

The MOLST is for people who already have a serious illness. It is signed by a physician after discussion with the patient or, if the patient lacks capacity, the proxy agent. The proxy designates the decision-maker; the MOLST records the binding orders. Where documents seem to conflict, they should be read together — generally the proxy controls who decides, while the living will and MOLST inform what is decided. I recommend reviewing all of them together whenever a health condition changes.

If You Have No Proxy: The Family Health Care Decisions Act

If you never sign a proxy and lose capacity, New York's Family Health Care Decisions Act (FHCDA), Public Health Law § 2994-a and following, supplies a default surrogate hierarchy — roughly: a court-appointed guardian, then a spouse or domestic partner, an adult child, a parent, an adult sibling, and finally a close friend. The FHCDA fills a gap, but it is no substitute for choosing your own agent. The default surrogate may not be the person you would have picked, the statute constrains how that surrogate may act, and disputes about who has priority can stall urgent decisions.

How the Proxy Interacts With Article 81 Guardianship

A well-drafted health care proxy can help your family avoid a guardianship proceeding altogether. If you have appointed an agent, a court is far less likely to need to appoint a guardian under Mental Hygiene Law Article 81 to make medical decisions for you. New York courts are directed to use the "least restrictive" intervention, and an existing, valid proxy is strong evidence that a guardian is unnecessary for health care purposes. Where a guardianship does occur, the court can — and often does — leave a properly functioning health care agent in place. This is one more reason a proxy is worth signing well before any crisis arises. If a court does become involved, see our discussion of disputes over a fiduciary's authority and concerns about an agent abusing their authority.

Keeping and Updating Your Proxy

You can change your agent at any time simply by signing a new proxy; the old one is revoked. Otherwise the proxy stays in effect until you revoke it or, if you chose one, until an expiration date you wrote in. Practical steps I recommend:

• Give signed copies to your agent, successor agent, and primary physician.
• Keep a wallet card noting where your proxy is stored and who your agent is.
• Re-review the document after major life events — marriage, divorce, the death of an agent, a serious diagnosis, or a move.

A Simple Checklist Before You Sign

• Have you named a first agent and at least one successor?
• Does the form include HIPAA authorization?
• Have you addressed artificial nutrition and hydration?
• Are your two witnesses adults who are not your agent?
• Have you stated any religious or treatment limits you care about?
• Have you actually talked with your agent about your wishes?
• Do your living will and/or MOLST (if any) say something consistent with your proxy?

Speak With a New York Health Care Proxy Attorney

A health care proxy is a short document with long consequences. Getting the details right — successor agents, HIPAA language, nutrition-and-hydration instructions, and coordination with your other planning documents — is the difference between a proxy that works in a crisis and one that creates confusion.

Frequently Asked Questions

Is a New York health care proxy the same as a power of attorney? No. A health care proxy covers medical decisions under Public Health Law Article 29-C. A power of attorney covers financial and property decisions under the General Obligations Law. Most people need both.

Do I need a lawyer or a notary to sign one? New York does not require a notary. You need two adult witnesses, and your agent cannot be one of them. A lawyer is not legally required, but proper drafting avoids the common gaps described above.

Can I name more than one agent? You may name a successor agent who serves if the first cannot, but New York does not permit co-agents acting at the same time.

What happens to my proxy if I divorce? A divorce or legal separation automatically revokes your former spouse's appointment unless you re-affirm it in writing or sign a new proxy.

What if I never signed a proxy? The Family Health Care Decisions Act provides a default surrogate hierarchy, but the decision-maker may not be who you would have chosen, which is why a signed proxy is preferable.
