Health Care Power of Attorney Requirements in Nevada

At a glance

Nevada keeps its medical power of attorney in the same chapter as its financial one, but in a separate article: the Durable Power of Attorney for Health Care Decisions, Nev. Rev. Stat. §§ 162A.700 to 162A.870. Nevada does not fold the agent appointment into a combined "advance directive" the way many states do — in fact, § 162A.715 defines an "advance health-care directive" as simply "a power of attorney for health care." This page covers what it takes to appoint your health care agent.

Requirements one by one

Governing law and document

The health care article applies "to any power of attorney containing the authority to make health care decisions" (§ 162A.700). Nevada publishes an optional statutory form at § 162A.855, and two specialized forms — one for an adult with an intellectual disability (§ 162A.865) and one for an adult with dementia (§ 162A.870). You are not required to use any of them; the legal requirements below control whichever document you sign.

Who can sign

"Any adult person may execute" a Nevada health care power of attorney (§ 162A.790(1)). The document "must be signed by the principal" (§ 162A.790(2)). Nevada's statute does not provide for someone else signing on your behalf at your direction, and it does not set a special capacity test beyond being an adult — so plan to sign it yourself while you can.

Witnesses or notary

This is the core requirement, and Nevada gives you a choice. Your signature "must be: (a) Acknowledged before a notary public; or (b) Witnessed by two adult witnesses" (§ 162A.790(2)). You need one route or the other — a notarized signature does not also need witnesses, and two witnesses do not also need a notary.

Who can't witness or serve

Here Nevada is narrower than its own forms suggest. The only mandatory witness disqualification in the execution statute is this: "Neither of the witnesses to a principal's signature may be the owner, operator or employee of a nursing home if the principal resides in the nursing home" (§ 162A.790(3)). The older, broader list some forms and websites still show — no relatives, no health care providers, at least one disinterested witness — comes from an earlier version of this section that has since been amended out of the validity rule.

The limits on who may serve as your agent are stricter. You "may not name as agent" your health care provider, an employee of that provider, or the operator or an employee of a health care facility (§ 162A.840(1)). The one exception: that person can serve if they are your "spouse, legal guardian or next of kin" (§ 162A.840(2)).

When the agent can act

Nevada flips the usual default. In most states an agent's authority "springs" into effect only when a doctor finds you incapacitated. In Nevada the power is "effective when executed unless the principal provides in the power of attorney that it becomes effective at a future date or upon incapacity" (§ 162A.810(1)) — so by default it is live the moment you sign it. If you do choose the springing option, the power turns on only when "an advanced practice registered nurse, a physician, psychiatrist or licensed psychologist" determines in writing that you are incapacitated (§ 162A.810(2)).

Powers and limits

Once effective, your agent makes health care decisions for you when you cannot give informed consent yourself (§ 162A.790(1)). For life support specifically, the agent "must make decisions concerning the use or nonuse of life-sustaining treatment which conform to the known desires of the principal" (§ 162A.850(2)), which is why stating your wishes in the document matters.

Some decisions are off-limits to every agent. Under § 162A.850(1), the agent may not consent to:

• commitment or placement in a mental-illness treatment facility;
• convulsive treatment, psychosurgery, sterilization, or abortion;
• "aversive intervention" as defined in NRS 449A.203;
• experimental medical, biomedical, or behavioral treatment or research; or
• anything you yourself prohibit in the document.

How to revoke

The power ends when "the principal revokes the power of attorney" or on a termination date you set (§ 162A.820(1)). Your agent's authority separately ends if "an action is filed for the dissolution or annulment of the agent's marriage to the principal, unless the power of attorney otherwise provides" (§ 162A.820(2)(c)) — so filing for divorce from a spouse-agent cuts off their authority even before the divorce is final. One caution: a revocation "is not effective as to the agent or another person that, without actual knowledge of the termination, acts in good faith" (§ 162A.820(4)), so tell your providers and your agent when you revoke.

Out-of-state directives

A directive from another state travels well. One "executed in a jurisdiction outside of this State is valid in this State if, when the power of attorney was executed, the execution complied with the laws of that jurisdiction" — or with the federal military power-of-attorney rule, 10 U.S.C. § 1044b (§ 162A.790(4)).

What trips people up

• The witness rules are looser than the forms make them look. Nevada's own statutory forms and many law-firm templates still print the old instruction that a witness cannot be a relative, an heir, or a health care provider. The binding execution statute today bars only nursing-home owners, operators, and employees, and only when you live in that nursing home (§ 162A.790(3)). Using the stricter witnesses is fine, but they are not required for validity.
• It works the moment you sign, unless you say otherwise. Because Nevada's default is immediate effect (§ 162A.810(1)), a signer who assumes the document "only kicks in if I'm incapacitated" is wrong unless they wrote that in. If you want it to wait, say so in the document.
• Your doctor cannot be your agent — with a family exception. A treating provider or facility employee is barred as agent (§ 162A.840(1)) unless they are your spouse, guardian, or next of kin (§ 162A.840(2)).

Common questions

Does a Nevada health care power of attorney have to be notarized? No. You can either have your signature notarized or have two adults witness it (§ 162A.790(2)). Either one is enough on its own.

Can a family member witness it? Yes. The execution statute's only witness restriction involves nursing-home staff where you reside (§ 162A.790(3)); relatives are not disqualified from witnessing.

When does my agent's authority start? Immediately when you sign, unless your document says it starts later or only on incapacity (§ 162A.810(1)).

If I divorce my spouse, can they still make my medical decisions? No — once a divorce or annulment action is filed, your spouse-agent's authority ends unless the document says otherwise (§ 162A.820(2)(c)).
