How a Mental Health Care Power of Attorney Works in Practice

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

A mental health care power of attorney takes effect as soon as it is signed and stays in effect until revoked. If the document specifically authorizes inpatient psychiatric admission, the agent can apply to have the principal admitted, but only after a physician conducts a thorough evaluation and determines that inpatient care is necessary.

When the Document Takes Effect

Unlike some legal documents that require a triggering event before they become active, a mental health care power of attorney is effective immediately upon execution. It remains in effect until the principal revokes it under A.R.S. 36-3285 or a court issues an order ending it. The agent's authority to make decisions, however, only activates when the principal is found incapable.

A mental health care power of attorney is effective when it is executed and remains in effect until it is revoked by the principal pursuant to section 36-3285 or by court order.

A.R.S. § 36-3284(A)

Safeguards for Inpatient Psychiatric Admission

If the mental health care power of attorney specifically authorizes inpatient admission, the agent can apply for the principal's admission to a licensed psychiatric facility. But the law does not allow this to happen without oversight. Before admission, a licensed physician must conduct a thorough investigation of the principal's psychiatric history, interview both the principal and the agent, obtain informed consent from the agent, and make a written determination that inpatient care is necessary and cannot be accomplished in a less restrictive setting.

Arizona also protects patients who want out. If a patient admitted under a mental health care power of attorney requests discharge in writing and wants to revoke the document or disqualify the agent, the facility must either discharge the patient or initiate court-ordered evaluation proceedings within 48 hours (excluding weekends and holidays). This safeguard ensures that the power of attorney cannot be used to keep someone confined against their will indefinitely.

After admission, the facility must review the principal's condition and the appropriateness of the placement at least once every 30 days. The agent may participate in each review, and should do so in person when possible. These ongoing reviews prevent situations where a patient remains in a facility longer than medically necessary.

A. A mental health care power of attorney is effective when it is executed and remains in effect until it is revoked by the principal pursuant to section 36-3285 or by court order. B. Notwithstanding the procedures and requirements prescribed in chapter 5, articles 4 and 5 of this title relating to involuntary court-ordered evaluation or treatment, if the mental health care power of attorney specifically authorizes the agent to admit the principal to an inpatient psychiatric facility and the agent has reasonable cause to believe that the principal is in need of an evaluation or treatment, the agent may apply for admission of the principal for evaluation or treatment at an inpatient psychiatric facility. The agent must present the facility with a copy of the power of attorney that specifically authorizes the agent to admit the principal to an inpatient psychiatric facility. If admission is requested by the agent, the facility to which the agent applies may admit the principal if before admission a physician who is licensed pursuant to title 32, chapter 13 or 17 does all of the following: 1. Conducts an investigation that carefully probes the principal's psychiatric and psychological history, diagnosis and treatment needs. 2. Conducts a thorough interview with the principal and the agent. 3. Obtains the agent's informed consent, as defined in section 36-501. 4. Makes a written determination that the principal needs an evaluation or will benefit from inpatient care and treatment of a mental disorder or other personality disorder or emotional condition and that the evaluation or treatment cannot be accomplished in a less restrictive setting. 5. Documents in the principal's medical chart a summary of the doctor's findings and recommendations for treatment. C. If a patient admitted to or being treated in an inpatient psychiatric facility under the authority of an agent pursuant to a mental health care power of attorney manifests the desire to disqualify an agent or to revoke a mental health care power of attorney and requests in writing to be discharged from the facility, the facility shall either discharge the patient or initiate proceedings for court ordered evaluation or treatment pursuant to chapter 5 of this title: 1. Within forty-eight hours after the facility receives this request, excluding weekends and legal holidays. 2. On the following court day if the forty-eight-hour period expires on a weekend or holiday. D. The discharge requirement prescribed in subsection C of this section does not apply if the facility is prohibited from discharging the person under federal law or if the principal has been determined to be incapable as defined in section 36-3281, the treating physician believes that further inpatient treatment is necessary or advisable and the agent under the power of attorney has consented to the continued treatment. E. After admission, if the patient refuses treatment or requests discharge and the treating physician believes that further inpatient treatment is necessary or advisable, the facility may rely on the consent of the agent for treatment, release and discharge decisions pursuant to the agent's authority under the power of attorney. F. The inpatient psychiatric facility licensed by the department of health services shall conduct a review of the principal's condition and need for admission into the facility and assess the appropriateness of the principal's placement at least once every thirty days. The agent may participate in each review. If possible the agent shall participate in person.
