Reforming a Trust to Fix Mistakes in Arizona

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

If a trust's written terms do not reflect what the person who created it actually intended, Arizona courts can reform the trust to fix the error. This applies even when the trust language appears clear on its face, as long as clear and convincing evidence shows both the intent and the wording were affected by a mistake.

Title 14, ARIZONA TRUST CODE

When Clear Language Still Gets It Wrong

Trust documents are drafted by humans, and humans make mistakes. A wrong account number, a misidentified beneficiary, a tax provision that contradicts the settlor's stated goals. Traditionally, courts were reluctant to rewrite trust language that seemed unambiguous. This statute changes that approach.

The court may reform the terms of a trust, even if unambiguous, to conform the terms to the settlor's intention if it is proved by clear and convincing evidence that both the settlor's intent and the terms of the trust were affected by a mistake of fact or law, whether in expression or inducement.

A.R.S. § 14-10415

The standard is clear and convincing evidence, which is higher than the typical preponderance standard used in most civil cases. The petitioner must show two things: that the settlor had a specific intention, and that a mistake of fact or law caused the trust language to miss the mark. The mistake can be in the expression itself, meaning the document says something the settlor did not mean, or in the inducement, meaning the settlor relied on incorrect information when making their decision.

Why This Matters for Families

Trust reformation can prevent outcomes nobody wanted. Consider a trust that directs assets to a charity that no longer exists, or one that includes a tax provision based on a law that has since changed. Without reformation, beneficiaries might be stuck with terms that defeat the very purpose the settlor had in mind.

This statute gives families a path to fix those problems through the court rather than living with the consequences of a drafting error. It is an important safety net, but it requires solid documentation. Letters, emails, meeting notes, and testimony from the attorney who drafted the trust can all serve as evidence of what the settlor actually intended.

The court may reform the terms of a trust, even if unambiguous, to conform the terms to the settlor's intention if it is proved by clear and convincing evidence that both the settlor's intent and the terms of the trust were affected by a mistake of fact or law, whether in expression or inducement.

Related Questions

Should I amend or restate my trust?

For one or two small changes, an amendment is usually sufficient. For multiple changes or a trust with several existing amendments, a restatement gives you a clean document. Neither requires retitling any assets.

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.

Can I change or cancel my Living Trust after it is created?

Yes. A Revocable Living Trust can be amended or revoked at any time as long as you are mentally competent. Once you become incapacitated, the document is locked and no one can change it.
