Section 3281: Mental Health Care Power of Attorney

An Arizona mental health care power of attorney is a written document in which a competent adult names another adult to make psychiatric treatment decisions on their behalf if a qualified specialist later determines they cannot give informed consent. The governing statutes begin at § 36-3281, and the document takes effect the moment it is properly signed. It stays in force until you revoke it or a court terminates it.¹

What This Document Actually Covers

You (the “principal”) name one or more adults (your “agents”) to make mental health treatment decisions if you become incapable of making them yourself. You can also name alternates who step in if your first choice is unavailable or unwilling. The agent’s authority only activates after a qualified professional finds you cannot give informed consent, and every decision the agent makes must follow the preferences you have written into your directive or POA.¹

This is narrower than a general health care POA. A general health care POA under § 36-3221 covers medical decisions broadly; the mental health version is dedicated to psychiatric and behavioral health. If you have no mental health care POA, your general health care agent can make mental health decisions for you when you are incapable, subject to exceptions in the statute. For anyone who wants specific control over psychiatric treatment, the dedicated document is the better tool.¹

How to Make It Valid

Miss one execution step and the document may fail when you most need it. To be enforceable, an Arizona mental health care POA must meet each of the following:²

You must be capable at the time you sign. You cannot create this document after being found incapable under the statute.
It must be in writing. Oral designations do not count.
It must clearly state your intent to create a mental health care power of attorney, not just a general POA or advance directive.
You must date and sign it, or mark it. If you cannot sign due to a physical limitation, the notary or witness must note on the document that you indicated it reflected your wishes and that you intended to adopt it.
It must be notarized or witnessed by at least one adult. That person affirms in writing that they were present when you signed and that you appeared to be of sound mind and free from duress, fraud, or undue influence.

Who Cannot Witness or Notarize

Two categories of people are barred from serving as your witness or notary: anyone you have designated to make medical decisions for you, and any professional care provider directly involved in your care at the time of signing. If you use a single witness rather than a notary, that witness also cannot be related to you by blood, marriage, or adoption, and cannot be a person who would inherit from your estate.²

The Extra Step for Inpatient Admission

Watch this one carefully. For your agent to have the power to admit you to an inpatient psychiatric facility, the POA must say so explicitly, and you must separately initial each paragraph granting that authority at the time of signing.² A broad general grant of authority over mental health decisions is not enough. If you skip the initialing, your agent cannot consent to inpatient care on your behalf, even if the POA is otherwise flawless.

Who Can Be Your Agent

Your agent must be an adult, and cannot be someone directly involved in providing your health care at the time you sign. Your current psychiatrist, therapist, or counselor is disqualified for that reason.¹ The statute does not otherwise limit choice based on criminal history, finances, or profession.

Practically, though, your agent will be making high-stakes calls during difficult moments. Pick someone who understands your treatment preferences, can handle hard conversations with medical staff, and will push for what you actually want. Name alternates. If your primary agent is traveling, ill, or unreachable during a crisis, an alternate keeps the chain intact.

When the Agent’s Authority Kicks In

Your agent cannot start making decisions just because a relative or general practitioner thinks you need help. Arizona defines “incapable” narrowly: a physician specializing in neurology or psychiatry, or a licensed psychologist, must conclude you lack the ability to give informed consent. The physician must hold an Arizona medical license under the relevant chapters of Title 32, and the psychologist must be licensed under Chapter 19.1 of the same title.¹

In practice, the evaluating professional is asking two questions. Can you understand what a proposed treatment involves, including its risks? Can you communicate a decision about it? If either answer is no, you meet the threshold, and your agent’s authority activates.³ This is a higher bar than many people expect. A bad week or a disagreement with your treatment team does not make you incapable.

What the Agent Can Do, and the Limits

Once you are found incapable, your agent steps in for mental health decisions. That can include consenting to or refusing medication, approving therapy plans, and, if the POA specifically grants it with proper initialing, consenting to inpatient admission at a licensed psychiatric facility.⁴ Every decision must track the preferences you have documented.¹

The authority exists only while you are incapable. Once you can give informed consent again, the agent’s power pauses. And there is a critical safeguard for inpatient stays: if you have been admitted under your agent’s authority and you request discharge in writing, the facility must either release you or begin court-ordered evaluation proceedings within 48 hours, excluding weekends and holidays.⁵ An agent-authorized admission is never a one-way door.

How It Fits with Other Directives

If you have both a mental health care POA and a general health care POA, the mental health version controls for psychiatric decisions. If you have only a general health care POA under § 36-3221, that agent can make mental health decisions when you are incapable, with exceptions spelled out in § 36-3283. Whichever agent is acting, their decisions must stay consistent with any wishes you have written into a mental health care directive, POA, or other advance directive.¹

A dedicated mental health care POA lets you spell out preferences a general document rarely captures: medication types you prefer or refuse, your attitude toward hospitalization, and preferences about specific procedures such as electroconvulsive therapy. Writing those preferences directly into the document gives your agent a clear mandate and reduces friction with family and providers. If you already have several directives, review them together for consistency. Conflicting instructions cause confusion exactly when clarity matters most.

HIPAA and Your Psychiatric Records

Naming an agent does not automatically hand them full access to your records, and this catches people off guard. Under HIPAA, when a patient is incapacitated, a provider may share information with someone involved in the patient’s care if doing so is in the patient’s best interest, so your agent will generally see the clinical information needed for treatment decisions.⁶

Psychotherapy notes are the exception. HIPAA defines these as a therapist’s personal notes from private counseling sessions, kept separate from the standard medical record. Disclosing them requires a specific written authorization from the patient, even to another healthcare provider.⁶ A mental health care POA alone may not satisfy that. If you want your agent to see session notes, include a specific HIPAA authorization in your planning documents. Routine information like medication lists, diagnoses, and treatment plans is not classified as psychotherapy notes and is generally available.

Revoking or Changing It

You can revoke the whole POA, revoke part of it, or disqualify a specific agent at any time.⁷ Even if you have been admitted to a facility under your agent’s authority, you can put a request in writing to disqualify the agent or revoke the POA and ask for discharge. Once the facility receives that written request, the same 48-hour clock applies: it must discharge you or initiate court-ordered evaluation proceedings.⁵

Revisit the document periodically. A move, a divorce, a falling out with your agent, or a change in your treatment preferences can all make an existing POA outdated. Executing a new POA that expressly revokes the old one is the cleanest way to keep things current.
