How Notice Works Under Arizona Trust Law

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

Arizona's trust code requires that notice to beneficiaries and other parties be delivered in a way that is reasonably likely to reach them. First class mail, personal delivery, and electronic messages all qualify. Notice can be waived, and a trustee is not required to notify someone whose identity or location cannot reasonably be determined.

Title 14, ARIZONA TRUST CODE

azleg.gov

Acceptable Methods of Giving Notice

Trust administration involves regular communication. Trustees notify beneficiaries of distributions, accounting reports, changes to administration, and other important events. This statute sets the standard for how that notice must be delivered.

Notice to a person under this chapter or the sending of a document to a person under this chapter must be accomplished in a manner reasonably suitable under the circumstances and likely to result in receipt of the notice or document. Permissible methods of notice or for sending a document include first class mail, personal delivery, delivery to the person's last known place of residence or place of business or a properly directed electronic message.

A.R.S. § 14-10109(A)

The key phrase is "reasonably suitable under the circumstances." Arizona does not require certified mail or hand delivery for every communication. A properly addressed first class letter or a well-directed email can satisfy the requirement. The standard is practical: did the trustee choose a method that was likely to actually reach the person?

When Notice Is Not Required

Sometimes a trustee genuinely cannot locate a beneficiary. The person may have moved without leaving a forwarding address, or the trust may name a class of beneficiaries (like "all grandchildren") where some members are unknown. Arizona addresses this directly.

Notice otherwise required under this chapter or a document otherwise required to be sent under this chapter need not be provided to a person whose identity or location is unknown to and not reasonably ascertainable by the trustee.

A.R.S. § 14-10109(B)

A beneficiary can also waive notice entirely. This sometimes happens in family trusts where beneficiaries prefer less formal communication. The waiver must come from the person who would otherwise receive the notice. For judicial proceedings involving a trust, notice follows the more formal requirements of A.R.S. 14-1401 rather than the flexible standards in this section.

14-10109. Methods and waiver of notice A. Notice to a person under this chapter or the sending of a document to a person under this chapter must be accomplished in a manner reasonably suitable under the circumstances and likely to result in receipt of the notice or document. Permissible methods of notice or for sending a document include first class mail, personal delivery, delivery to the person's last known place of residence or place of business or a properly directed electronic message. B. Notice otherwise required under this chapter or a document otherwise required to be sent under this chapter need not be provided to a person whose identity or location is unknown to and not reasonably ascertainable by the trustee. C. Notice under this chapter or the sending of a document under this chapter may be waived by the person to be notified or sent the document. D. Notice of a judicial proceeding must be given pursuant to section 14-1401.

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.

What is a Revocable Living Trust and how does it work?

A Revocable Living Trust lets you transfer asset ownership into a trust you control during your lifetime. When you pass, a successor trustee distributes assets to beneficiaries without probate.

How do I prepare my successor trustee to manage my estate?

Create a binder or digital folder listing financial accounts, professional advisors, document locations, bill payment details, and contacts. Your trustee should not have to guess their way through your estate.
