Surrogate Authority and Responsibilities for Health Care Decisions in Arizona

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

A surrogate authorized to make health care decisions in Arizona must follow the patient's wishes as expressed in the health care directive. If the directive does not cover a specific situation, the surrogate relies on their knowledge of the patient's values, or, if those are unknown, acts in the patient's best interest.

Title 36, LIVING WILLS AND HEALTH CARE DIRECTIVES

How a Surrogate Makes Decisions

Being named as a health care surrogate carries real weight. Arizona law lays out a clear hierarchy for how decisions should be made, starting with the patient's own words.

The surrogate shall make health care decisions for the patient in accordance with the patient's wishes as expressed in the health care directive. If the health care directive does not provide sufficient information to know what the patient would want in a particular circumstance, the surrogate shall base these decisions on the surrogate's knowledge of the patient's values if those are known or can be determined to the surrogate's satisfaction.

A.R.S. § 36-3203(C)

This three-tier framework matters. The directive comes first. If it does not address the situation, the surrogate looks to the patient's values and preferences as they understood them. Only when neither source provides guidance does the surrogate fall back on a "best interest" standard.

Protection and Limits

Arizona law protects surrogates who act in good faith. A surrogate making genuine, well-intentioned decisions is not subject to civil or criminal liability. Courts can only override that protection with clear and convincing evidence of an improper motive.

The statute also sets firm boundaries. A surrogate cannot consent to anything the patient could not lawfully consent to. And a surrogate who is not the patient's agent or guardian cannot approve the permanent withdrawal of artificially administered food or fluid. That restriction ensures the most consequential decisions stay in the hands of someone with direct legal authority from the patient or the court.

One practical note: a surrogate is not financially responsible for the patient's health care costs unless they would be required to pay regardless of the surrogate role.

36-3203. Surrogate; authority; responsibilities; immunity A. A person authorized as a surrogate to make health care decisions under this chapter is not responsible for paying the patient's health care costs unless the person is otherwise required to do so. B. This chapter does not authorize a surrogate to consent to any act or omission to which the patient could not lawfully consent. C. The surrogate shall make health care decisions for the patient in accordance with the patient's wishes as expressed in the health care directive. If the health care directive does not provide sufficient information to know what the patient would want in a particular circumstance, the surrogate shall base these decisions on the surrogate's knowledge of the patient's values if those are known or can be determined to the surrogate's satisfaction. If neither the health care directive nor the surrogate's knowledge of the patient's values provides a sufficient basis for making a health care decision, the surrogate shall decide based on the surrogate's good faith belief as to what is in the patient's best interest. D. A surrogate who makes good faith health care decisions for a patient is not subject to civil or criminal liability for those decisions. Acts and refusals to act made in reliance on the provisions of a health care directive are presumed to be made in good faith. A court shall base a finding of an absence of good faith on information known to the surrogate and shall enter its finding only after it has made a determination of bad faith in written findings of fact based on clear and convincing evidence of improper motive. For the purposes of this subsection, "good faith" includes all health care decisions, acts and refusals to act based on a surrogate's reasonable belief of a patient's desires or a patient's best interest if these decisions, acts or refusals to act are not contrary to the patient's express written directions in a valid health care directive. E. A surrogate who is not the patient's agent or guardian shall not consent to or approve the permanent withdrawal of the artificial administration of food or fluid.

Related Questions

Who makes medical decisions if I do not have a power of attorney in Arizona?

Arizona law (A.R.S. 36-3231) creates a priority list: spouse, adult children (majority must agree), parent, domestic partner, sibling, then close friend. If no one is available, your doctor decides after consulting an ethics committee.

Is a living will the same as a DNR in Arizona?

No. A living will covers end-of-life treatment preferences (ventilator, feeding tubes, comfort care). A DNR (called a Pre-Hospital Medical Care Directive in Arizona, printed on orange paper) only tells emergency responders not to perform CPR.

What is the difference between a Healthcare Power of Attorney and a Living Will?

A Healthcare Power of Attorney appoints someone to make medical decisions for you. A Living Will states your preferences for end-of-life treatment. Most estate plans include both documents.
