The prudent investor rule is a fiduciary standard for how a trustee invests and manages trust assets. It generally asks whether the trustee used reasonable care in pursuing a strategy suited to the trust’s purposes, terms, distribution needs, and circumstances—not whether each investment looks prudent on its own. The applicable version is the law of the governing jurisdiction, read alongside the trust instrument.
What the prudent investor rule means
The Uniform Law Commission (ULC) created the Uniform Prudent Investor Act (UPIA) as a model for rules governing trustees who invest trust property. States enact and interpret their own laws, so the UPIA itself is not a single nationwide statute. The ULC’s overview explains the model’s focus on risk and return, beneficiary needs, economic conditions, taxes, and liquidity: Uniform Prudent Investor Act.
In states that have adopted the framework, the trustee’s investment decisions are assessed in light of the trust’s purposes, terms, distribution requirements, and other relevant circumstances. The standard is contextual: it concerns the overall portfolio and investment strategy rather than requiring every individual asset to be safe or profitable in isolation.
How a trustee decides whether an investment is prudent
The trustee must consider whether an investment fits the trust’s overall strategy and risk-and-return objectives. Kansas law states: “In satisfying this standard, the fiduciary shall exercise reasonable care, skill and caution.” It also requires a reasonable effort to verify facts relevant to investment and management decisions. See Kan. Stat. Ann. § 58-24a02.

Relevant factors depend on local law and the trust’s circumstances. Kansas lists considerations such as:
- General economic conditions and the possible effects of inflation or deflation.
- Expected tax consequences of investment decisions.
- Each investment’s role in the portfolio and its expected total return, including income and capital appreciation.
- The trust’s liquidity, regular-income, and capital-preservation or appreciation needs.
- Other resources available to beneficiaries.
- An asset’s special relationship or value to the trust or a beneficiary.
Connecticut’s statute also identifies factors such as related trusts, portfolio size, and the trust’s estimated duration. These statutory lists are examples, not a universal checklist; the controlling state’s law determines which factors apply. Kansas permits any kind of property or investment consistent with its standards, but that does not make every investment prudent in every trust.
Does the prudent investor rule require diversification?
Generally, diversification is required under the Kansas and Texas provisions cited here, unless the fiduciary reasonably determines that special circumstances make the trust’s purposes better served without it. The exception is fact-specific: it is not automatic permission to keep a concentrated holding.
Kansas’s diversification provision states the rule and exception in Kan. Stat. Ann. § 58-24a03. Texas likewise evaluates investments in the context of the portfolio and recognizes an exception when special circumstances support not diversifying: Texas Estates Code, Chapter 117.

It can, depending on the governing state’s law and the instrument’s terms. Connecticut’s statute expressly treats its prudent-investor provisions as a default rule that trust provisions may alter. See Conn. Gen. Stat. § 45a-541. Do not assume the same wording or effect applies everywhere: read the trust document together with the governing jurisdiction’s statute and relevant case law.

The UPIA is a model act, not a substitute for state law. The examples above illustrate provisions in Kansas, Texas, and Connecticut; they are not a survey of every state. A specific trust’s answer may depend on which fiduciaries the local law covers, whether the instrument modifies default rules, the statutory factors, local case law, and the facts. This overview addresses trustee investment duties and should not be treated as a statement of the separate standards that may govern investment advisers, employee benefit plans, or other fiduciary relationships.

For a particular investment decision or dispute, identify the trust’s governing law, review the full instrument, and consult a lawyer qualified in that jurisdiction.
