When Third Parties Are Protected in Custodial Transfers

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

Arizona law protects banks, brokerages, and other third parties who deal with a custodian in good faith. As long as a third party has no actual knowledge of a problem, they are not responsible for verifying the custodian's authority, the validity of the transfer, or how custodial property is used.

Title 14, TRUST ADMINISTRATION

azleg.gov

Good Faith Protections for Third Parties

When a custodian manages property for a minor, banks, investment firms, and other institutions need to interact with that custodian regularly. This statute removes a significant burden from those third parties by establishing a good-faith safe harbor. If someone presents themselves as a custodian and gives instructions, a third party can follow those instructions without conducting an independent investigation.

A third person in good faith and without court order may act on the instructions of or otherwise deal with a person purporting to make a transfer or purporting to act in the capacity of a custodian and, in the absence of knowledge, is not responsible for determining: 1. The validity of the purported custodian's designation.

A.R.S. § 14-7666

The protection covers four specific areas. A third party does not need to verify that the custodian was properly designated, that the custodian's actions are authorized under the statute, that any transfer documents are valid, or that custodial property is being applied correctly for the minor's benefit.

What "Good Faith" Means in Practice

The key phrase is "in the absence of knowledge." If a bank has no reason to believe something is wrong, it can process transactions without liability. But if the institution has actual knowledge that a custodian is misusing funds or acting without authority, the protection does not apply. This balance keeps custodial accounts practical to administer while preserving accountability when problems are obvious.

For families, this means custodial transfers and account management tend to move smoothly. Financial institutions do not need to demand extensive documentation every time a custodian makes a routine transaction on behalf of a minor.

A third person in good faith and without court order may act on the instructions of or otherwise deal with a person purporting to make a transfer or purporting to act in the capacity of a custodian and, in the absence of knowledge, is not responsible for determining: 1. The validity of the purported custodian's designation. 2. The propriety of, or the authority under this article for, any act of the purported custodian. 3. The validity or propriety pursuant to this article of any instrument or instructions executed or given either by the person purporting to make a transfer or by the purported custodian. 4. The propriety of the application of any property of the minor delivered to the purported custodian.

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.

How do I choose the right trustee for my estate?

Choose a trustee based on competence, not convenience. Avoid naming all children as co-trustees, which creates gridlock. Pick your most capable child as primary and name a backup.
