Can a California Trustee Delegate Trust Functions?

Trustee delegation in California is governed by Probate Code § 16012, and it represents a genuine departure from the old common-law rule. Traditionally, a trustee could hand off only ministerial busywork — filing paperwork, routine administrative tasks — while every discretionary decision had to stay with the trustee personally, because the settlor chose that individual to exercise judgment.

Modern practice looks very different. Trustees regularly hire investment managers, accountants, and property managers. Knowing exactly where the line sits between proper delegation and improper abdication is essential both for the California Bar Exam and for any trustee managing real trust assets today.

What is trustee delegation? Delegation is a trustee’s transfer of trust-administration functions to an agent. Under California Probate Code § 16012 and the Uniform Prudent Investor Act, a trustee may delegate investment and management functions if the trustee exercises reasonable care in selecting the agent, defining the scope of delegation, and periodically reviewing performance.

The Traditional Rule: No Delegation of Discretion

Before modern statutes relaxed the rule, a trustee could delegate only ministerial or administrative tasks — things like preparing tax returns or handling routine correspondence. Discretionary functions, especially investment and distribution decisions, could not be delegated at all. The rationale was straightforward: the settlor selected this trustee specifically to exercise personal judgment, and letting the trustee outsource that judgment would defeat the settlor’s intent.

The Modern Rule: § 16012’s Three-Prong Standard

California Probate Code § 16012 and the Uniform Prudent Investor Act now permit delegation of investment and management functions, but only if the trustee satisfies a three-part reasonable-care standard.

Selecting the agent. The trustee must exercise reasonable care, skill, and caution in choosing a qualified, reputable agent.
Establishing scope and terms. The delegation must be defined with clear instructions consistent with the purposes of the trust — not an open-ended handoff.
Periodic review. The trustee must monitor the agent’s performance on an ongoing basis to ensure compliance with the delegation’s terms.

Satisfying all three prongs shields the trustee from liability for the agent’s decisions, even if those decisions turn out to be imprudent in hindsight. Fail any one prong, and the trustee is exposed to liability as though the trustee had made the decision personally.

What Can — and Cannot — Be Delegated

Not every function is a candidate for delegation. The line runs between administrative/investment functions (delegable) and core discretionary judgments the settlor personally entrusted to this trustee (non-delegable).

Function	Delegable?	Example
Investment management	Yes	Hiring a professional money manager for the securities portfolio
Recordkeeping and accounting	Yes	Engaging a bookkeeper or CPA
Routine administrative tasks	Yes	Property maintenance coordination, tax filing
Discretionary distribution decisions	No	Deciding which beneficiary receives what amount, and when
Core judgment the settlor reposed in this trustee	No	Case-specific decisions the trust instrument commits to the trustee’s personal judgment

Attempting to delegate a non-delegable function is itself a breach — it doesn’t matter how competent the agent is. Even an outstanding financial advisor cannot cure a trustee’s improper handoff of discretionary distribution authority.

Trustee Liability: Proper Delegation vs. Abdication

The dividing line between lawful delegation and unlawful abdication comes down to ongoing engagement. A trustee who hires a qualified investment manager, gives that manager a clear written mandate consistent with the trust’s purposes, and reviews performance quarterly has delegated properly under § 16012 — and is shielded from liability even if the manager makes an imprudent trade.

Contrast that with a trustee who hands the manager full authority and never checks back in. That’s not delegation; it’s abdication. The trustee remains fully liable, because the third prong — periodic review — was never satisfied. The takeaway for practice and for the exam alike: delegation requires the trustee to stay engaged, not disappear.

Worked Example: Bar Exam Fact Pattern

Trustee Renata manages a $2 million trust with broad investment authority. She hires Meridian Advisors, a licensed registered investment adviser with a strong track record, to manage the trust’s securities portfolio. Renata provides Meridian with a written investment policy statement matching the trust’s income and growth objectives, and she reviews Meridian’s performance every quarter.

Analysis: Renata properly delegated under § 16012. She satisfied all three prongs: she selected a qualified agent with reasonable care, she established clear scope and terms through the investment policy statement, and she periodically reviewed performance. Even if Meridian makes an individual trade that loses money, Renata is not liable for that decision, because the delegation itself was proper.

Change the facts: Suppose instead Renata’s trust gives her discretion over how much income to distribute to each of three beneficiaries based on their individual needs, and Renata simply tells an outside financial planner, “You decide who gets what, I don’t want to deal with it,” with no further involvement. This is improper. Distribution discretion tied to each beneficiary’s individual circumstances is a non-delegable, core fiduciary judgment the settlor entrusted to Renata personally. Renata remains liable for any resulting harm, regardless of the planner’s competence.

Common Mistakes to Avoid

Students often assume § 16012 authorizes blanket delegation of any trustee function — it doesn’t; discretionary decisions the settlor reposed in the trustee stay off-limits. A second common error is thinking that careful initial selection of the agent is enough on its own; the statute requires ongoing review too. A third mistake is assuming a highly competent agent cures an improper delegation of a non-delegable function — competence of the agent is irrelevant if the function itself couldn’t be delegated in the first place.

FAQ

What can a California trustee delegate under Probate Code § 16012?

A trustee may delegate investment and management functions — such as hiring an investment manager, accountant, or administrative staff — provided the trustee exercises reasonable care in selecting the agent, defining the scope of delegation, and reviewing performance periodically.

Can a trustee delegate distribution decisions?

Generally no. Discretionary distribution decisions that the settlor personally entrusted to the trustee’s judgment are considered non-delegable core fiduciary functions, distinct from investment or administrative tasks.

Is a trustee liable if a properly selected investment manager makes a bad trade?

Not necessarily. If the trustee satisfied all three prongs of § 16012 — proper selection, clear scope, and periodic review — the trustee is generally shielded from liability for the agent’s individual investment decisions, even ones that turn out poorly.

Key Takeaways

California Probate Code § 16012 permits trustees to delegate investment and management functions, reversing the old common-law bar on delegating discretion.
The three-prong standard requires reasonable care in selecting the agent, defining scope, and periodically reviewing performance.
Core discretionary decisions the settlor personally entrusted to the trustee — especially distribution judgment calls — remain non-delegable.
Proper delegation shields the trustee from liability for the agent’s decisions; improper delegation or abandonment (abdication) leaves the trustee fully liable.
On the bar exam, check all three prongs before concluding a delegation was proper — missing periodic review is the trap examiners use most often.
