If you are new to estate planning, the term “health care proxy” can sound intimidating. It is not. A health care proxy is simply a short legal document that lets you name a trusted person to make medical decisions for you if you ever cannot speak for yourself. That is the whole idea. In New York, this document is governed by Public Health Law Article 29-C, and it is one of the four foundational pieces of a complete estate plan.
This page is written for beginners. We will define the terms in everyday language, walk through how the document actually works, and show you where it fits alongside your will, your trusts, and your financial power of attorney. By the end, you will understand exactly what a New York health care proxy does — and why nearly every adult should have one.
What Is a Health Care Proxy? (Start Here)
A health care proxy is a document in which you (the “principal”) appoint another person to be your health care agent. If a doctor determines that you have lost the ability to make or communicate your own medical decisions, your agent steps in and makes those decisions for you.
Two terms to learn right away:
- Health care agent — the person you choose to speak for you. This can be a spouse, an adult child, a sibling, a close friend — anyone 18 or older whom you trust.
- Capacity — your ability to understand and decide. Your agent only has authority after a physician determines you lack capacity. As long as you can speak for yourself, you remain in charge.
That last point surprises many beginners: signing a health care proxy does not give away any control while you are healthy and able to decide. It is a backup that activates only when you genuinely need it.
101 takeaway: A health care proxy answers one question — “If I can’t tell the doctors what I want, who do I trust to tell them for me?”
Why Every New York Adult Should Have One
Without a health care proxy, if you become incapacitated — through an accident, a stroke, surgery complications, or advanced illness — no single person automatically has clear legal authority to direct your care. Family members may disagree. Doctors may be left guessing. In the worst case, your loved ones may have to ask a court to appoint a guardian, which is slow, public, and expensive.
A health care proxy avoids all of that. With one signed page, you decide in advance who speaks for you. It works statewide — whether you live in Manhattan, Brooklyn, or Queens, out on Long Island, up in Westchester and the Hudson Valley, or anywhere Upstate — because it is a single New York State document, not a county-specific one.
How the New York Health Care Proxy Works
New York’s health care proxy law (Public Health Law Article 29-C) sets out a clean, beginner-friendly structure. Here is the document broken down:
| Element | What It Means in Plain English |
|---|---|
| You name a primary agent | The first person who can make medical decisions for you. |
| You may name an alternate | A backup, in case your primary agent is unavailable or unwilling to serve. |
| Activation requires lost capacity | The agent’s authority begins only when a physician determines you cannot make decisions yourself. |
| Broad medical authority | Your agent can generally make any medical decision you could make, including consenting to or refusing treatment. |
| Artificial nutrition & hydration | Your agent can make decisions about feeding tubes and IV hydration only if the agent reasonably knows your wishes; many people state those wishes directly on the form. |
| Two adult witnesses | The form must be signed in front of two adult witnesses. The person you name as your agent should not serve as a witness. |
| You can revoke anytime | While you have capacity, you may cancel or change your proxy at any time. |
A health care proxy in New York does not need to be notarized — it needs two adult witnesses. It also does not expire on its own; it stays in effect until you revoke it or sign a new one.
Health Care Proxy vs. Living Will: Don’t Confuse the Two
Beginners often mix these up:
- A health care proxy names a person to make decisions.
- A living will is a written statement of your wishes (for example, your preferences about life-sustaining treatment).
They work best together: the proxy appoints the decision-maker, and the living will or written instructions tell that person what you would want. New York recognizes clearly expressed wishes, so spelling them out gives your agent both authority and guidance.
Where the Health Care Proxy Fits in Your Estate Plan
A health care proxy is powerful, but it is only one of four core documents. A comprehensive New York estate plan coordinates all four so they work together rather than at cross-purposes:
- Last Will and Testament — directs who receives your property after death. Under EPTL §3-2.1, a valid New York will requires two attesting witnesses, the testator’s signature at the end of the document, and publication (telling the witnesses it is your will). Dying without a will means intestacy, where state law under EPTL Article 4 decides who inherits.
- Trusts — hold and manage assets. Under EPTL Article 7, a revocable living trust helps your estate avoid probate (though it saves no estate tax), while an irrevocable trust is used for tax reduction, asset protection, and Medicaid planning (subject to a 5-year look-back). A Supplemental Needs Trust (EPTL 7-1.12) preserves a disabled beneficiary’s public benefits.
- Durable Power of Attorney — appoints someone to handle your financial affairs. Under General Obligations Law §5-1513, New York’s power of attorney is durable by default, using the 2021 statutory short form.
- Health Care Proxy — this page’s subject. It handles your medical decisions under Public Health Law Article 29-C.
The most important beginner insight here: the financial power of attorney and the health care proxy are two different documents. The POA (GOL §5-1513) covers money — bank accounts, bills, property. The health care proxy (PHL Article 29-C) covers medical care. One does not substitute for the other, and a complete plan needs both. See our estate planning overview for how the pieces connect.
Capacity, Incapacity, and the Court You Want to Avoid
The whole point of a health care proxy is to keep medical decisions inside your family and out of the courtroom. If you have no proxy and you lose capacity, your loved ones may have to petition a court to be appointed your guardian — a proceeding that costs time and money and puts your private affairs on the public record. A simple, properly witnessed health care proxy is the inexpensive insurance policy that prevents that outcome.
Does the Health Care Proxy Affect New York Estate Tax?
This is a common beginner question, and the answer is reassuring: no. A health care proxy is a medical document — it has nothing to do with taxes. Estate tax is driven by the size of your estate and the planning tools (like irrevocable trusts) you use, not by who makes your medical decisions.
That said, since you are building a complete plan, it helps to know the lay of the land. For 2026, New York’s basic exclusion amount is $7,350,000 for deaths on or after January 1, 2026 through December 31, 2026. New York also has a famous “cliff.” If your estate exceeds 105% of the exclusion — $7,717,500 — you lose the entire exemption and the whole estate is taxed from the first dollar, at progressive rates from 3% to 16%. New York imposes no gift tax, but gifts made within 3 years of death are added back to your taxable estate.
If your estate is anywhere near these numbers, the document that does the tax work is the irrevocable trust, not the health care proxy. Read our New York estate tax guide for the full picture, and our statewide estate planning guide for how all of this applies across the state.
How to Set Up Your Health Care Proxy: A Beginner’s Checklist
- Choose your agent. Pick someone who is calm under pressure, will honor your wishes, and is reachable in an emergency.
- Choose an alternate. Name a backup in case your first choice cannot serve.
- Talk to them. Tell your agent your values and preferences about treatment so they can carry them out.
- Put your wishes in writing. Consider adding instructions about life-sustaining treatment and artificial nutrition and hydration.
- Sign with two adult witnesses. Remember, your chosen agent should not be one of the witnesses.
- Store and share it. Give copies to your agent, your doctor, and keep one with your other estate documents.
- Coordinate the whole plan. Make sure your will, trusts, POA, and proxy were prepared to work together — this is where an attorney adds the most value.
Frequently Asked Questions
Q: What is the difference between a health care proxy and a power of attorney in New York?
A health care proxy (Public Health Law Article 29-C) covers medical decisions; a durable power of attorney (General Obligations Law §5-1513) covers financial decisions. They are separate documents, and a complete estate plan includes both.

Only after a physician determines that you have lost the ability to make or communicate your own medical decisions. While you still have capacity, you remain fully in charge of your own care.
Q: Does a New York health care proxy need to be notarized?
No. Under Public Health Law Article 29-C, the form must be signed in front of two adult witnesses. Notarization is not required, but your appointed agent should not serve as a witness.
