Standard of Care and Portfolio Strategy for Arizona Trustees

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

Arizona law requires trustees to invest as a prudent investor would, considering the trust's purpose, distribution needs, and the beneficiaries' circumstances. Investment decisions are judged by the overall portfolio, not by individual gains or losses on a single asset.

Title 14, ARIZONA TRUST CODE

azleg.gov

Investing With the Whole Picture in Mind

This statute spells out what it actually means to invest trust assets prudently. A trustee must consider the trust's purpose, its distribution schedule, tax consequences, inflation, and the beneficiaries' other resources. The standard is reasonable care, skill, and caution, not perfection.

A trustee shall invest and manage trust assets as a prudent investor would by considering the purposes, terms, distribution requirements and other circumstances of the trust. In satisfying this standard the trustee shall exercise reasonable care, skill and caution.

A.R.S. § 14-10902(A)

One of the most practical aspects of this statute is how it evaluates performance. A single investment that loses value does not automatically mean the trustee failed. The law looks at the portfolio as a whole, within the context of an overall strategy that balances risk and return for the trust's specific situation.

Factors a Trustee Must Consider

The statute lists specific factors that should guide investment decisions: general economic conditions, inflation or deflation, expected tax consequences, how each asset fits the broader portfolio, expected total return, the beneficiaries' other resources, liquidity needs, and whether an asset has special significance to the trust or a beneficiary.

A trustee's investment and management decisions respecting individual assets shall not be evaluated in isolation but in the context of the trust portfolio as a whole and as a part of an overall investment strategy having risk and return objectives reasonably suited to the trust.

A.R.S. § 14-10902(B)

The trustee also has a duty to verify facts relevant to investment decisions. This means doing homework, not just relying on assumptions. And the statute makes clear that no type of investment is automatically off-limits. Stocks, bonds, real estate, closely held businesses, and alternative investments are all permissible if they fit the trust's needs.

A. A trustee shall invest and manage trust assets as a prudent investor would by considering the purposes, terms, distribution requirements and other circumstances of the trust. In satisfying this standard the trustee shall exercise reasonable care, skill and caution. B. A trustee's investment and management decisions respecting individual assets shall not be evaluated in isolation but in the context of the trust portfolio as a whole and as a part of an overall investment strategy having risk and return objectives reasonably suited to the trust. C. Among circumstances that a trustee shall consider in investing and managing trust assets are any of the following that are relevant to the trust or its beneficiaries: 1. General economic conditions. 2. The possible effect of inflation or deflation. 3. The expected tax consequences of investment decisions or strategies. 4. The role that each investment or course of action plays within the overall trust portfolio, which may include financial assets, interests in closely held enterprises, specialty assets, alternative investments, tangible and intangible personal property and real property. 5. The expected total return from income and the appreciation of capital. 6. Other resources of the beneficiaries. 7. Needs for liquidity, regularity of income and preservation or appreciation of capital. 8. An asset's special relationship or special value, if any, to the purposes of the trust or to one or more of the beneficiaries. D. A trustee shall make a reasonable effort to verify facts relevant to the investment and management of trust assets. E. A trustee may invest in any kind of property or type of investment consistent with the standards of this article.

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.

Should I use a bank or a professional fiduciary as my trustee?

Banks require $300K-$5M+ minimums and charge 0.5%-2% annual fees. Professional fiduciaries are licensed by the Arizona Supreme Court, charge $65-$250/hour, handle any estate size, and also serve as healthcare and financial POA.

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.
