How Incapacity Is Determined Under Arizona's Custodial Trust Act

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

Arizona law sets out how a custodial trustee determines whether a beneficiary is incapacitated. The trustee can rely on the beneficiary's prior directions, a physician's certificate, or other persuasive evidence. Incapacity does not end the trust or remove the trustee's authority.

Title 14, UNIFORM CUSTODIAL TRUST ACT

Three Paths to an Incapacity Determination

A custodial trustee does not need a court order to determine that a beneficiary has become incapacitated. Arizona provides three methods the trustee can rely on.

A custodial trustee may determine that the beneficiary is incapacitated by relying on: 1. Previous direction or authority given by the beneficiary while not incapacitated, including direction or authority pursuant to a durable power of attorney. 2. The certificate of the beneficiary's physician. 3. Other persuasive evidence.

A.R.S. § 14-9110(B)

The most common path is a physician's certificate. A doctor who has examined the beneficiary provides a written statement about their condition. The trustee can also look to instructions the beneficiary gave while competent, including directions in a durable power of attorney about how incapacity should be handled.

Incapacity Does Not End the Trust

One of the most important protections in this statute is what happens after incapacity is established. The custodial trust continues. The trustee's powers remain intact. Any designated successor custodial trustee remains in place. And third parties who acted on the trustee's instructions remain protected.

If the beneficiary later recovers, the trustee can return to managing the trust as if the beneficiary were competent. The statute also provides for court involvement: any interested person can petition the court to determine whether the beneficiary is actually incapacitated. This acts as a safeguard against mistakes or disagreements about the beneficiary's condition.

When a trustee has reason to believe a beneficiary is incapacitated but has not yet made a formal determination, the statute directs the trustee to manage the trust under the incapacity provisions. This prevents delays in care while the determination is being finalized.

A. The custodial trustee shall administer the custodial trust as for an incapacitated beneficiary if either: 1. The custodial trust was created under section 14-9105. 2. The transferor has so directed in the instrument creating the custodial trust. 3. The custodial trustee has determined that the beneficiary is incapacitated. B. A custodial trustee may determine that the beneficiary is incapacitated by relying on: 1. Previous direction or authority given by the beneficiary while not incapacitated, including direction or authority pursuant to a durable power of attorney. 2. The certificate of the beneficiary's physician. 3. Other persuasive evidence. C. If a custodial trustee for an incapacitated beneficiary reasonably concludes that the beneficiary's incapacity has ceased or that circumstances concerning the beneficiary's ability to manage property and business affairs have changed since the creation of a custodial trust directing administration as for an incapacitated beneficiary, the custodial trustee may administer the trust as for a beneficiary who is not incapacitated. D. On petition of the beneficiary, custodial trustee or other person interested in the custodial trust property or the welfare of the beneficiary, the court shall determine whether the beneficiary is incapacitated. E. Absent a determination of incapacity of the beneficiary under subsection B or D of this section, a custodial trustee who has reason to believe that the beneficiary is incapacitated shall administer the custodial trust in accordance with the provisions of this chapter applicable to an incapacitated beneficiary. F. Incapacity of a beneficiary does not terminate: 1. The custodial trust. 2. Any designation of a successor custodial trustee. 3. Rights or powers of the custodial trustee. 4. Any immunities of third persons acting on instructions of the custodial trustee.

Why do I need a Financial Power of Attorney?

Without a Financial Power of Attorney, your family may face a costly conservatorship to manage your finances. This document lets you choose who handles your money and when their authority begins.

How do guardianship and conservatorship proceedings work in Arizona?

Both require filing with the Arizona Superior Court, medical evidence of incapacity, and a judge's approval. The process takes months and costs thousands. Powers of attorney accomplish the same goals without court involvement.

What does a trustee actually do?

A trustee manages trust assets according to the rules the trust creator set. While you are alive, you are typically both trustor and trustee. After you pass, your successor trustee distributes assets as instructed.
