    Life Events Affecting a Trust

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

    When a marriage, divorce, death, or other life event changes how a trust works, the trustee is protected from liability if they took reasonable steps to learn about the event. A trustee who did not know is not on the hook for losses caused by that lack of knowledge.

    Title 14, ARIZONA TRUST CODE

    Life Events That Change Trust Administration

    Trusts do not exist in a vacuum. The terms of the trust often tie provisions to real-life milestones. A beneficiary getting married, a divorce, completing a degree, or someone passing away can change who receives distributions, how much they receive, or how assets held in the trust are managed going forward.

    If the happening of an event, including marriage, divorce, performance of educational requirements or death, affects the administration or distribution of a trust, a trustee who has exercised reasonable care to ascertain the happening of the event is not liable for a loss resulting from the trustee's lack of knowledge.

    A.R.S. § 14-11007

    The challenge for trustees is that they may not always know when these events happen. A beneficiary might get divorced in another state. A grandchild might finish a college degree without telling anyone involved in the trust.

    Reasonable Care Is the Standard

    The law does not require trustees to be all-knowing. The standard is reasonable care. If a trustee makes genuine efforts to stay informed, they are protected from liability for what they could not reasonably have known.

    This matters for a revocable living trust that becomes irrevocable after the creator's death. At that point, distribution rules often shift based on life events among the beneficiaries. Protection trusts may include conditions that only trigger when specific milestones are met.

    Life events can also affect federal estate tax planning built into the trust. If a beneficiary's marriage or death changes the tax treatment of assets held in the trust, the trustee needs current information to make proper decisions.

    Communication between trustees and beneficiaries matters. Trustees who stay in regular contact are better positioned to follow the terms of the trust correctly. And beneficiaries who keep their trustee informed about major life changes help the entire process run smoothly.

    If the happening of an event, including marriage, divorce, performance of educational requirements or death, affects the administration or distribution of a trust, a trustee who has exercised reasonable care to ascertain the happening of the event is not liable for a loss resulting from the trustee's lack of knowledge.
