A.R.S. § 14-10104

What Counts as 'Knowledge' in Trust Law

Verified April 4, 202657th Legislature, 1st Regular Session

The trust code defines what it means to 'know' something about a trust. Actual knowledge, receiving a notice, or having enough facts that you should have known all count. For organizations like banks, knowledge is tied to the employee handling the trust account.

Title 14, ARIZONA TRUST CODE

Three Ways Knowledge Is Established

Trust law often hinges on whether someone knew a particular fact. Did the trustee know about a creditor's claim? Did the bank know the account holder had passed away? Under the Arizona revised statutes, this section spells out exactly what qualifies as knowledge in the trust code.

A person has knowledge of a fact if any of the following apply: 1. The person has actual knowledge of it. 2. The person has received a notice or notification of it. 3. From all the facts and circumstances known to the person at the time in question, the person has reason to know it.

A.R.S. § 14-10104(A)

The third category is the broadest. You do not need to have been told directly. If the circumstances were clear enough that a reasonable person would have figured it out, the law treats you as if you knew.

How This Applies to Banks and Other Organizations

When a revocable trust is held at a bank, brokerage, or other organization, the rules work differently. The organization only "knows" something once the employee responsible for the trust account receives the information. It also counts if that employee would have received it had the organization followed reasonable internal procedures.

An organization that conducts activities through employees has notice or knowledge of a fact involving a trust only from the time the information was received by an employee having responsibility to act for the trust or would have been brought to the employee's attention if the organization had exercised reasonable diligence.

A.R.S. § 14-10104(B)

This matters in practice. If you notify a bank's general customer service line about a trust matter, the clock on their "knowledge" may not start until the information reaches the right department. Organizations are expected to maintain reasonable communication routines. However, they are not required to have every employee monitoring every trust account.

Why This Matters for Beneficiary Interest

Knowledge plays a direct role in how a beneficiary interest is protected. Trustees have a duty to inform and report to the people who have a stake in the trust. That includes distributees of trust income and anyone else with a right to be informed about the administration of trust assets.

For families, this means you should always send the qualified beneficiaries written notice of important changes. Verbal conversations may not count. Putting things in writing creates a clear record that knowledge was delivered.

If a trustee handles trust income or principal without telling the right people, those beneficiaries may have legal grounds to challenge the decision. The knowledge rules protect families by making sure that the people who matter are kept in the loop.

14-10104. Knowledge A. Subject to subsection B, a person has knowledge of a fact if any of the following apply: 1. The person has actual knowledge of it. 2. The person has received a notice or notification of it. 3. From all the facts and circumstances known to the person at the time in question, the person has reason to know it. B. An organization that conducts activities through employees has notice or knowledge of a fact involving a trust only from the time the information was received by an employee having responsibility to act for the trust or would have been brought to the employee's attention if the organization had exercised reasonable diligence. An organization exercises reasonable diligence if it maintains reasonable routines for communicating significant information to the employee having responsibility to act for the trust and there is reasonable compliance with the routines. Reasonable diligence does not require an employee of the organization to communicate information unless the communication is part of the individual's regular duties or the individual knows a matter involving the trust would be materially affected by the information.
