Who Makes Medical Decisions If You Are Incapacitated in Nevada

If you become mentally incapacitated in Nevada without an advance directive, the state does not hand decision-making to whoever shows up at the hospital first. Nevada law establishes a strict, non-negotiable priority list — and it contains rules that surprise most families.

The Statutory Surrogate Hierarchy

Under the Nevada Uniform Act on Rights of the Terminally Ill, when a patient lacks decisional capacity and has no designated healthcare agent, authority to consent to or refuse life-sustaining treatment follows this exact order:

1. Spouse of the patient
2. Adult children — if more than one, a majority of those reasonably available for consultation
3. Parents of the patient
4. Adult siblings — again, a majority of those reasonably available
5. Other relatives by blood or adoption within the legal degree of consanguinity (excludes in-laws)
6. Any adult who has exhibited special care and concern for the patient, is deeply familiar with their personal values, and is willing to act in their best interest

The hierarchy is strict. The hospital cannot skip to class 3 (parents) just because your adult children are difficult to reach. Only if no one in the higher-priority class exists or is available does authority pass to the next level.

The Majority Rule and the Deadlock Problem

Here is where the system breaks down for many families. If you have three adult children and they are split 2-1 on a treatment decision, the majority rules. But if you have two adult children who disagree, the hierarchy does not resolve the deadlock by moving to your parents.

The split class must either reach consensus or the parties must petition the district court for judicial resolution. That means a courtroom fight over your medical care — with all the cost, delay, and emotional damage that entails.

The Written Consent Requirement

The Nevada Supreme Court has established a requirement that catches families off guard: any surrogate consent to withhold or withdraw life-sustaining treatment must be in writing and attested by two independent witnesses who have personal knowledge of the surrogate's consent and intent.

A verbal statement to a physician — "Mom would have wanted this" — is not legally sufficient in Nevada. The surrogate must put their consent in writing, and two witnesses must sign confirming they heard or observed the surrogate giving that consent.

This requirement adds time and complexity to an already emotionally devastating situation. While the family is processing grief and shock, they must also navigate a formal attestation process before the hospital will act on their decision.

Who Has No Standing

Several categories of people are explicitly excluded from Nevada's default surrogate hierarchy:

• Unmarried, unregistered partners. If you are cohabiting but not married and not a registered domestic partner, you have zero standing under the default hierarchy. Your partner of 20 years has less legal authority than a distant cousin related by blood.
• In-laws. The hierarchy covers relatives by blood or adoption, not by marriage. Your son-in-law or daughter-in-law cannot serve as a default surrogate.
• Friends (unless they qualify under class 6, which requires demonstrating special care, familiarity with your values, and willingness to act — a standard that hospitals interpret narrowly).

How an Advance Directive Changes Everything

Executing an advance directive under NRS 162A.855 replaces this entire hierarchy with a single designated agent of your choosing. Your agent does not need to be a relative. They do not need majority agreement from anyone. They do not need written attestation witnessed by two people. They present the directive (or the hospital retrieves it from the Lockbox), and they make the call.

For unmarried partners, this is not optional — it is the only way to ensure your partner has any voice in your medical care. For families with potential disagreements among adult children, it prevents the deadlock scenario entirely.

The Nevada Advance Directive & Living Will Kit walks you through naming your agent and structuring alternates so your medical decisions are never left to a committee vote or a courtroom.
