The short answer is this: a health care proxy lets someone make your medical decisions when you cannot, while a power of attorney lets someone manage your financial and legal affairs. They are two separate New York documents governed by two separate laws, and they appoint your agents for two completely different jobs. One does not cover the other — which is why a complete New York estate plan includes both, working side by side. If you only sign one, you leave half of your life unprotected at exactly the moment you need protection most.
Below is a clear, plain-English overview written for someone meeting this topic for the first time. By the end you will know what each document does, who controls what, the New York statutes behind them, and how they fit into a coordinated plan.
What a Health Care Proxy Does in New York
A health care proxy is authorized by New York Public Health Law Article 29-C. It lets you name a trusted person — called your health care agent — to make medical decisions on your behalf if you lose the ability to decide for yourself.
Your agent can step in for choices such as:
- Consenting to or refusing medical treatment, surgery, or tests
- Choosing doctors, hospitals, or care facilities
- Making decisions about life-sustaining treatment, consistent with your wishes
- Accessing your medical records to make informed choices
A key point: the health care proxy only “switches on” when a physician determines that you lack capacity to make your own medical decisions. As long as you can speak for yourself, you remain in charge. The proxy is about who speaks for you when you cannot speak for yourself — nothing more.
It is worth knowing that a health care proxy is not the same as a living will. A living will records your specific wishes (for example, about end-of-life care), while the proxy names the person empowered to act. Many New Yorkers use both together so their agent has both authority and guidance.
What a Power of Attorney Does in New York
A power of attorney (POA) is governed by New York General Obligations Law §5-1513, which contains the 2021 statutory short form. This document lets you name an agent (sometimes called an attorney-in-fact) to handle your financial and legal matters.
Depending on the powers you grant, your agent may:
- Pay bills and manage bank accounts
- Handle real estate transactions
- File taxes and deal with government benefits
- Manage investments and business interests
Under §5-1513, a New York power of attorney is durable by default — meaning it stays in effect even if you later become incapacitated. (You can change this, but durability is the standard.) This durability is exactly what makes the POA so valuable: it keeps your financial life running without a court having to appoint a guardian for you.
Note that the financial POA gives your agent no authority over medical decisions. That gap is precisely what the health care proxy fills.
Side-by-Side: The Core Differences
| Feature | Health Care Proxy | Power of Attorney |
|---|---|---|
| Governing law | NY Public Health Law Article 29-C | NY General Obligations Law §5-1513 |
| Decisions covered | Medical / health care | Financial / legal |
| Person you appoint | Health care agent | Agent (attorney-in-fact) |
| When it activates | Only when you lack medical capacity | Immediately or upon a stated event; durable by default |
| Typical powers | Treatment, providers, life-sustaining care | Banking, real estate, taxes, benefits |
| Covers the other area? | No financial authority | No medical authority |
The table makes the takeaway obvious: these documents do not overlap. Each one closes a gap the other leaves open.
Why You Need Both — and How They Fit a Larger Plan
Imagine you are hospitalized and unable to communicate. Your health care agent decides on your treatment. Meanwhile, your mortgage is due, your insurance needs a signature, and your accounts need managing — and your health care agent has zero authority over any of that. Without a power of attorney, your family may have to petition a court to manage your finances. Without a health care proxy, they may face the same hurdle for medical decisions.
That is why a comprehensive New York estate plan coordinates four core tools together: a will, one or more trusts, a durable power of attorney, and a health care proxy. The proxy and POA protect you while you are alive; the will and trusts direct your assets after death.

A quick look at how the other pieces connect:
- Will (EPTL §3-2.1): A valid New York will requires two attesting witnesses, the testator’s signature at the end, and publication. Dying without a will (intestacy) means New York’s default rules under EPTL Article 4 decide who inherits — not you. Learn more on our Wills page.
- Trusts (EPTL Article 7): A revocable living trust avoids probate (though it offers no estate-tax savings), while an irrevocable trust can reduce taxes, protect assets, and support Medicaid planning (subject to the 5-year look-back). A Supplemental Needs Trust (EPTL 7-1.12) preserves benefits for a loved one with disabilities. See our Trusts page.
A Note on the New York Estate Tax
While the proxy and POA are about lifetime decisions, planning should keep the 2026 New York estate tax in view. For deaths on or after January 1, 2026, the basic exclusion is $7,350,000. New York also imposes a notorious “cliff” at 105% of the exclusion — $7,717,500. An estate that exceeds the cliff 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. For the full picture, read our NY Estate Tax Guide.
Frequently Asked Questions
Can one person be both my health care agent and my financial agent?
Yes. Many New Yorkers name the same trusted person in both documents. You still need to sign both the health care proxy and the power of attorney, because each grants authority under a different law.
Does a power of attorney let my agent make medical decisions?
No. A New York power of attorney under GOL §5-1513 covers only financial and legal matters. Medical decision-making requires a separate health care proxy under Public Health Law Article 29-C.
When does my health care proxy take effect?
Only when a physician determines you lack the capacity to make your own medical decisions. Until then, you remain fully in control of your own care.
Is a New York power of attorney durable automatically?
Yes. Under GOL §5-1513, the statutory short-form power of attorney is durable by default, meaning it remains valid if you become incapacitated — though you may modify this in the document.
Talk to a New York Estate Planning Attorney
A health care proxy and a power of attorney are simple to describe but easy to get wrong if the forms are outdated or the powers are mismatched. The 2021 statutory short form and the Article 29-C proxy both have strict execution requirements, and they work best when coordinated with your will and trusts as one plan.
