Changing a Trust When Circumstances Were Not Anticipated

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

When conditions arise that the person who created the trust did not foresee, Arizona courts can step in to modify or terminate the trust. The court's goal is to carry out the settlor's probable intention as closely as possible, even when the original terms no longer work as planned.

Title 14, ARIZONA TRUST CODE

When Life Changes Faster Than the Trust

A trust may have made perfect sense when it was created. But laws change. Tax rules shift. Family situations evolve. When circumstances arise that the settlor could not have anticipated, rigid trust terms can work against the very people the trust was meant to help. Arizona law gives courts the authority to step in.

The court may modify the administrative or dispositive terms of a trust or terminate the trust if, because of circumstances not anticipated by the settlor, modification or termination will further the purposes of the trust. To the extent practicable, the modification must be made in accordance with the settlor's probable intention.

A.R.S. § 14-10412(A)

The standard is practical: would the modification help achieve what the settlor originally intended? The court is not rewriting the trust on a whim. It is adjusting the terms to fit a reality the settlor never imagined.

Administrative Adjustments for Efficiency

Sometimes the issue is not the trust's purpose but how it operates day to day. Investment restrictions that once made sense may now be impracticable. Administrative costs may have grown out of proportion. The statute gives courts a separate basis to modify purely administrative terms when continuing under the existing rules would be wasteful or impair the trust's management.

The court may modify the administrative terms of a trust if continuation of the trust on its existing terms would be impracticable or wasteful or would impair the trust's administration.

A.R.S. § 14-10412(B)

If the court ultimately terminates the trust under this section, the trustee distributes the property in a manner consistent with the trust's purposes. The goal is always to honor what the settlor intended, adapted to current reality.

A. The court may modify the administrative or dispositive terms of a trust or terminate the trust if, because of circumstances not anticipated by the settlor, modification or termination will further the purposes of the trust. To the extent practicable, the modification must be made in accordance with the settlor's probable intention. B. The court may modify the administrative terms of a trust if continuation of the trust on its existing terms would be impracticable or wasteful or would impair the trust's administration. C. On termination of a trust under this section, the trustee shall distribute the trust property in a manner consistent with the purposes of 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.

Why is funding your trust so important?

An unfunded trust provides no probate protection because it only controls assets it actually holds. Re-funding is needed after life changes like refinancing, new accounts, or inheritances.

Can two unmarried people create a joint trust in Arizona?

Yes. Unmarried couples, parent-child pairs, and siblings can create a joint trust in Arizona. The trust must clearly define each person's ownership share since community property rules do not apply to unmarried co-trustors.
