State-specific notes
•Witnesses cannot be the agent. PHL §2981(2)(a)
•The health care proxy may NOT be executed on the same form or writing as a power of attorney. PHL §2981(5)(e) (the statute prohibits combination but does not expressly state the invalidation consequence for post-1991 combined writings; the savings clause in §2981(5)(e) protects only delegations executed before Article 29-C's 1991 enactment, so a post-1991 combined writing risks invalidating the proxy).
•Audio-video remote witnessing is allowed (PHL §2981(2-a): photo ID display if not personally known, real-time A/V interaction, 24-hour transmission, remote-witness signature on transmitted copy).
•Say what you want about artificial nutrition and hydration. Under the statutory Health Care Proxy form at PHL §2981, your agent has no authority to decide about artificial nutrition and hydration unless your agent knows your wishes about it. Mark the artificial nutrition and hydration line in the Health Care Instructions section, or write your wishes into Additional Instructions, and talk it through with your agent. Leaving that line to your agent's discretion is the one choice that does not give your agent authority.
•Who you may not name as your agent. If you are a patient or resident of, or have applied for admission to, a hospital, and article 29-C counts a nursing home, a mental hygiene facility and a hospice as a hospital, you may not name an operator, administrator or employee of that facility as your health care agent unless that person is related to you by blood, marriage or adoption. A physician, physician assistant or nurse practitioner may be named, but must decline the appointment if they want to go on acting as your attending practitioner, and a physician or nurse practitioner affiliated with a mental hygiene facility or a psychiatric unit of a general hospital may not serve for a principal residing in or treated by that facility or unit unless related to you. Anyone who is not your spouse, child, parent, brother, sister or grandparent, or the issue or spouse of one of those, may not be named if they already serve as health care agent for ten principals (N.Y. Pub. Health Law §2981(3); §2980(9)).
•Extra witness rules apply if you live in a mental hygiene facility. If the facility is operated or licensed by the Office of Mental Health, at least one witness must be unaffiliated with the facility, and if that facility is also a hospital as defined by the Mental Hygiene Law (§1.03), at least one witness must be a qualified psychiatrist or psychiatric nurse practitioner (PHL §2981). If the facility is operated or licensed by the Office for People With Developmental Disabilities, at least one witness must be unaffiliated and at least one must be a physician, nurse practitioner, physician assistant, or clinical psychologist meeting the statute's criteria (PHL §2981).
