Enforcement and Defense of Claims: A Trustee's Legal Duty

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

Arizona law requires a trustee to take reasonable steps to pursue claims the trust may have against others and to defend the trust against claims brought by third parties. Sitting on the sidelines is not an option.

Title 14, ARIZONA TRUST CODE

azleg.gov

Active Protection, Not Passive Oversight

Being a trustee is not just about managing assets and distributing them to beneficiaries. It also means protecting the trust's legal interests. This statute makes that obligation explicit.

A trustee shall take reasonable steps to enforce claims of the trust and to defend claims against the trust.

A.R.S. § 14-10811

On the enforcement side, this could mean collecting debts owed to the trust, pursuing insurance claims, or taking legal action against someone who damaged trust property. If the trust is owed money or has a valid legal claim, the trustee cannot simply ignore it.

When the Trust Faces a Claim

On the defense side, the trustee must respond to lawsuits, creditor claims, or other legal challenges directed at the trust. Failing to respond could result in a default judgment that costs the trust, and the beneficiaries, significantly.

The standard is reasonableness, not perfection. A trustee does not have to pursue every possible claim regardless of cost. If the expense of litigation would outweigh the potential recovery, a prudent trustee might reasonably decide not to proceed. But the trustee must at least evaluate the situation and make an informed decision.

For families selecting a successor trustee, this duty highlights why the role requires someone who is willing to engage with difficult situations. A trustee who avoids conflict or ignores legal matters can put the entire trust at risk.

A trustee shall take reasonable steps to enforce claims of the trust and to defend claims against the trust.

Related Questions

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.

What is the hardest part of settling a trust?

If the trust is in proper order, settling it is straightforward and can begin in hours. The hardest part is not the legal process but the emotional weight of handling affairs while grieving, compounded by unfunded assets or missing information.
