A New York healthcare proxy is a written document in which you name one person to make medical decisions for you if you become unable to make them yourself. Without it, the people around you may face confusion, disagreement and, in some cases, a court proceeding at the worst possible time. We prepare healthcare proxies as part of a complete estate plan and supervise their signing so that they hold up when they are needed.
What a Healthcare Proxy Is Under New York Law
The healthcare proxy is authorized by Article 29-C of the New York Public Health Law. You, the principal, appoint another person, your healthcare agent, to make medical decisions for you when you lack the capacity to make them. The proxy does nothing while you can speak for yourself; it takes effect only when your attending physician determines that you are unable to make your own healthcare decisions.
Once it is activated, your agent’s authority is broad. The agent can consent to or refuse procedures, surgeries and treatments, choose your healthcare providers and facilities, access your medical records and protected health information, authorize or decline pain management and comfort care, and make end-of-life decisions consistent with the preferences you have stated. The agent can also decide about life-sustaining treatment, including artificial nutrition and hydration, but only if you have communicated your wishes on that subject.
That last point matters. New York requires that your agent know your wishes regarding artificial nutrition and hydration in order to make those specific decisions. A frank conversation with your chosen agent, and clear documentation of what you told them, is as much a part of the plan as the signed form.
Why a Healthcare Proxy Is Needed
Many people assume that a spouse, adult child or closest relative automatically has the right to make medical decisions for them. That is not always the case. New York’s Family Health Care Decisions Act provides a framework for surrogate decision-making in certain hospital and nursing home settings, but it has significant limitations and may not match your preferences about who should decide.
Without a proxy, relatives may disagree about your care, which delays treatment and strains the family. If no one has authority, your loved ones may have to petition for guardianship under Article 81 of the Mental Hygiene Law, a process that is time-consuming, expensive and public. Healthcare providers may default to aggressive treatment when your true wishes would have been otherwise, and the person who ends up making intimate decisions about your body may be someone you would not have chosen. A properly drafted proxy removes those risks by saying, in writing, who speaks for you and what you want.
Requirements for a Valid Proxy
The statute sets out what a valid New York healthcare proxy must contain and how it must be signed.
| Requirement | What the statute demands |
|---|---|
| Age and capacity | The principal must be at least 18 years old and have the mental capacity to understand the nature and consequences of appointing an agent. |
| Written document | The proxy must be in writing and identify the principal and the agent, and optionally an alternate agent. |
| Signature | The principal must sign and date the document, or direct another person to sign in the principal’s presence if the principal is physically unable to sign. |
| Two witnesses | Two adult witnesses must be present at the signing and must affirm that the principal appeared to act willingly and free from duress. The appointed agent cannot serve as a witness. |
Notarization is not required, but the document must be executed exactly as the statute prescribes. An ineligible witness or a missing signature can make a proxy unenforceable at the moment it is needed.
Choosing the Agent
The choice of agent is the most important decision in the process. The agent should understand your values, beliefs and preferences about medical care, be able to remain calm under pressure, and be willing to advocate for you even against pushback from other family members or from medical providers. Practical availability counts too: someone who lives reasonably close, or who can travel when needed, is more useful than someone who cannot. The agent must be at least 18 and, with limited exceptions, cannot be your treating physician or healthcare provider.
We recommend naming an alternate agent in case the primary agent is unavailable, unwilling or unable to serve, and we document the backup designation in the same instrument. Note that New York does not permit two people to serve as co-agents at the same time; only one agent can act at a time, which is why the alternate is named as a successor rather than a partner.
How the Proxy Relates to Other Advance Directives
A healthcare proxy is one piece of an advance care plan. New York recognizes several related documents, each with a distinct job.
-
Living will
A living will is a written statement of your preferences about life-sustaining treatment such as ventilators, feeding tubes and resuscitation. New York has no specific living will statute, but courts recognize these documents as clear and convincing evidence of your wishes. It complements the proxy by giving your agent specific guidance. See our comparison of a will and a living will.
-
MOLST form
The Medical Orders for Life-Sustaining Treatment form is a medical order signed by a physician that translates your treatment preferences into instructions for emergency responders and healthcare providers. It is typically used by people with serious illness or advanced age.
-
Power of attorney
A statutory power of attorney covers financial and legal decisions, not medical ones. In New York these are separate documents governed by different statutes, and a complete plan usually includes both a healthcare proxy and a durable power of attorney.
-
HIPAA authorization
The proxy gives your agent access to medical information once it is activated. A separate HIPAA release lets designated people receive information from your providers even before you lose capacity.
Mistakes We See, and What They Cost
Well-intentioned people often sign proxies that fail to do what they wanted. The recurring problems are these.
| Mistake | Consequence |
|---|---|
| Using a generic online form | Templates often miss New York-specific requirements or say nothing about artificial nutrition and hydration, leaving the agent without authority over those decisions. |
| Never discussing wishes with the agent | The agent must know what you would want. The conversation matters as much as the document. |
| Naming co-agents | New York law does not permit two people to serve as co-agents simultaneously. Only one agent can act at a time. |
| Not updating after life changes | Divorce, the death of the agent or a change in family circumstances can leave the wrong person in charge. |
| Keeping the document hidden | A proxy no one can find is useless. Copies belong with your agent, your primary physician and trusted family members. |
When to Review or Revoke the Proxy
A New York healthcare proxy does not expire unless you write an expiration date into it, but it should be reviewed from time to time. Revisit it when you marry, divorce or separate; when your agent dies, becomes ill or moves; when your relationship with the agent changes significantly; when you receive a serious diagnosis; when your values or treatment preferences change; and in any event when five or more years have passed since the last review.
As long as you have capacity, you can revoke or amend the proxy at any time by notifying your agent and your healthcare providers, orally or in writing.
What We Do
We start by learning your values, your family situation and any medical concerns, and then draft a proxy that reflects your specific instructions, including provisions on artificial nutrition and hydration, organ donation and religious considerations where they apply. We integrate the proxy with your living will, power of attorney, will and any trusts so that the documents do not contradict each other, and we supervise the signing so that it complies with the statute. Where it helps, we sit down with your chosen agent and family so that the people who will carry out your wishes have heard them from you. We remain available to update the documents as circumstances change and to advise the agent if questions come up later.
Situations That Need Extra Care
For unmarried couples and LGBTQ+ individuals, a proxy is essential to give a partner decision-making authority that biology alone does not provide. In blended families, a clear designation prevents disputes between a spouse and adult children from a prior relationship. Parents of adult children should know that once a child turns 18 the parents lose automatic authority to make medical decisions, and a proxy signed by the child can restore it. For clients with chronic illness we coordinate with physicians so that the proxy, the MOLST form and the care plan line up, and for seniors entering long-term care, proper documentation can prevent a guardianship proceeding and make the transition smoother.
