You're in a car accident. You're unconscious. The doctors need to make a decision about your treatment. Who speaks for you?

If you have a healthcare proxy, your named agent does. They know you. They understand your values. They speak with authority. The doctors listen.

If you don't have one, the hospital calls your family. If your family disagrees about what you'd want, you might have a problem. If you have no family — or if your family relationships are complicated — the hospital turns to New York's Family Health Care Decisions Act, which creates a hierarchy of decision-makers based on legal relationship, not on who actually knows you best.

A healthcare proxy is one of the most important documents you'll ever sign. And it takes less than 30 minutes to execute properly.

What Is a New York Healthcare Proxy?

A healthcare proxy is a document authorized by New York Public Health Law Article 29-C that lets you designate an agent to make healthcare decisions for you if you lose the ability to make them yourself. It's sometimes called a "healthcare power of attorney" in other states, though New York uses specific terminology.

The proxy activates when your attending physician determines — and a second physician concurs — that you lack the capacity to make healthcare decisions. Until that point, you make your own decisions. Once the physicians make their determination, your agent steps in.

Who Can Execute a Healthcare Proxy?

Any New York adult (18 or older) who is of sound mind can execute a healthcare proxy. You must be competent at the time of signing. You don't need an attorney to execute a healthcare proxy — the law provides a standard form — but having it done as part of a complete estate plan ensures it's properly integrated with your other documents.

Formal Requirements

Under New York Public Health Law Section 2981, a valid healthcare proxy must:

Witness restrictions matter. Neither of the following can serve as a witness:

If you're a patient in a hospital or nursing home, the healthcare proxy has additional execution requirements to prevent undue influence.

Who Can Be Your Healthcare Agent?

Your healthcare agent can be any adult who is willing to serve — a spouse, adult child, sibling, close friend, or any other trusted person. The only people who cannot serve as your agent:

You can name an alternate (successor) agent who steps in if your primary agent is unavailable, unwilling, or unable to serve. Name one. Circumstances change, and having no backup means a gap in coverage when you need it most.

What Decisions Can the Agent Make?

Your healthcare agent can make any healthcare decision you could make yourself — with one critical exception we'll discuss in a moment.

That means the agent can:

The Artificial Nutrition and Hydration Exception

Under New York law, your healthcare agent cannot consent to the withholding or withdrawal of artificial nutrition and hydration (feeding tubes, IV fluids) unless you explicitly authorized this in the proxy document itself.

This is the most common gap I see in healthcare proxies drafted without legal guidance. A proxy that grants broad healthcare authority but doesn't specifically address artificial nutrition may not protect your wishes if that situation arises. If you want your agent to be able to make decisions about artificial nutrition — including in a terminal condition or permanent vegetative state — you must say so explicitly in the document.

The New York State Health Department provides a standard form healthcare proxy. It's legally valid. But the standard form has blank spaces for instructions and doesn't prompt you to address artificial nutrition or hydration specifically. A properly drafted proxy tailored to your wishes closes these gaps.

Healthcare Proxy vs. Living Will: What's the Difference?

These two documents are often confused, and they're often confused with each other. They serve different functions.

A healthcare proxy is about who makes decisions. It names your agent and gives them authority. The agent then makes judgment calls based on the circumstances — adapting to situations you couldn't have anticipated.

A living will (sometimes called an advance directive or healthcare directive) is about what decisions get made. It states your own preferences — whether you want aggressive life-sustaining treatment in a terminal condition, what your wishes are about resuscitation, organ donation, and so on.

In an ideal world, you have both. The living will guides your agent. Your agent uses judgment to interpret your directive in light of specific medical circumstances.

New York doesn't have a statutory living will form the way some states do. Living wills in New York are enforced under the common law right to refuse treatment and under the Family Health Care Decisions Act. A properly drafted living will is more powerful than a vague one, and having an attorney prepare it ensures your wishes are clearly expressed.

The Family Health Care Decisions Act: What Happens Without a Proxy

If you have no healthcare proxy and you lose capacity, New York's Family Health Care Decisions Act (FHCDA) — enacted in 2010 — creates a hierarchy of people who can make decisions for you:

  1. A court-appointed guardian, if you have one
  2. Your spouse or domestic partner
  3. A parent or adult child
  4. A sibling
  5. A close friend

This sounds reasonable until you consider the scenarios where it fails. If you're estranged from your spouse, they still come first. If you have multiple children who disagree, the one highest on the list prevails — or they fight. If your closest confidant is a longtime friend rather than a family member, that friend has no authority until every closer relative has been exhausted.

And the FHCDA only applies in hospital and nursing home settings. For many other care settings, no surrogate decision-making framework applies at all without a healthcare proxy.

A healthcare proxy you choose controls who speaks for you. The FHCDA default controls who legally must.

HIPAA Authorization: The Companion Document

A healthcare proxy grants decision-making authority. But there's a related gap: HIPAA, the federal health privacy law, restricts who your medical providers can share information with — even if you're incapacitated.

A HIPAA authorization form lets you designate specific people who can receive your medical information. Without it, your agent may have trouble getting information from providers who aren't sure whether they're allowed to share it. Your adult children may not be able to get updates on your condition.

This is a simple document but an important one. It should accompany your healthcare proxy as a standard part of any estate planning package.

When Should You Execute a Healthcare Proxy?

Now. There's no waiting for a particular age or health condition. The proxy is useful for anyone over 18. Unexpected incapacity can happen at any age — accidents, sudden illness, emergency surgery — not just in old age.

Practically speaking, it becomes especially urgent when:

A healthcare proxy must be executed while you have capacity. If cognitive decline has progressed to the point that you can no longer understand what you're signing, it's too late. This is especially urgent for clients or families dealing with early-stage dementia — the window is open, but it closes.

Choosing Your Healthcare Agent

This is the most personal decision in the entire estate planning process. Here's how I guide clients through it.

The right agent is someone who:

The agent doesn't have to be a family member. A close friend who knows you better than your estranged sibling is a far better choice than a relative who hasn't spoken to you in years. The legal relationship matters less than the actual relationship.

How to Have the Conversation with Your Agent

Naming someone as your agent without telling them what you want is only half the job. They need to know your wishes.

Have a real conversation. Tell them how you feel about:

These conversations are uncomfortable. Most people avoid them. But your agent making decisions without this context is working blind — and the decisions they make may not reflect what you'd actually want.

Healthcare Proxy as Part of a Complete Plan

A healthcare proxy works best as part of a coordinated estate plan. It handles medical decisions. A durable power of attorney handles financial decisions. A will or revocable trust handles asset distribution after death. Together, these documents cover the full range of needs that arise from incapacity and death.

For seniors especially, all of these documents need to work together — and they should all be reviewed periodically for currency and consistency. See our guide on estate planning for seniors in New York for how the full picture fits together.

For parents, ensuring that your kids have healthcare proxies when they turn 18 is as important as having one yourself. The moment your child turns 18, your parental authority to make their medical decisions ends. They need a proxy naming you — or whoever they choose. Our guide on estate planning for parents in New York covers this and other family planning considerations.

At Morgan Legal Group, we prepare healthcare proxies, living wills, HIPAA authorizations, powers of attorney, wills, and trusts as a coordinated package. Each document is drafted to be consistent with the others, and each is explained so you understand exactly what you're signing and why it matters.

Updating Your Healthcare Proxy

Review your healthcare proxy every three to five years or after significant life changes — divorce, the death of a named agent, a major health diagnosis, or a change in your relationship with the named agent. A healthcare proxy can be revoked at any time you have capacity, orally or in writing, simply by expressing your intent to revoke it.

If you execute a new healthcare proxy, make sure old versions don't create confusion. Give copies to your agent, your doctors, your hospital if you're a frequent patient, and anyone else likely to be involved in your care decisions.
