Directed vs. Discretionary Trustee: What's the Difference?

August 16, 2026

First Hill Trust

Key Takeaways

  • Both kinds of trustee hold your plan's assets. The core difference is who makes the investment decisions: the trustee itself, or your committee telling the trustee what to do. Liability and monitoring duties follow from that.
  • A directed trustee acts on instructions from a fiduciary your plan names, often the investment committee. A discretionary trustee makes the investment decisions itself and answers for those decisions.
  • A directed trustee is still a fiduciary under federal law. A directed trustee’s duties are much narrower than a discretionary trustee’s, but the narrower list still carries real obligations.
  • Under either arrangement, one duty stays with the sponsor: choosing the trustee carefully and reviewing that choice on a regular schedule.

Why This Matters

Your plan documents name a trustee. What they may not make obvious is which of two very different jobs that trustee holds, because the same word covers both: a trustee that takes instructions from a fiduciary your plan names, and a trustee that makes the investment decisions on its own authority.

Which job your trustee holds decides who is responsible for the plan’s investment decisions. A plan can be years past its setup with nobody on the current committee certain which arrangement the plan has. If you are not certain which one your plan uses, this post covers what each arrangement means, and then the documents that answer the question.

Our Fiduciary Role Comparison Guide puts the two arrangements next to each other, duty by duty, and includes a worksheet for mapping who holds each duty in your own plan.

What Is the Difference Between a Directed and a Discretionary Trustee?

Both kinds of trustee hold the plan’s assets in trust, separate from company money. The core difference is who chooses the plan’s investments, and the differences in liability and monitoring follow from that.

A directed trustee acts on instructions. Your plan names a fiduciary to give those instructions. That fiduciary can be your investment committee, or an investment manager the plan hired. The committee decides to add a fund or drop one, and the trustee carries out that decision. The committee decides. The directed trustee executes and safekeeps.

A discretionary trustee decides without instructions. The trustee selects the investments, monitors performance, and makes changes without seeking your committee’s approval. Because the trustee makes those decisions, the trustee is responsible for them.

Those are the two ways a trustee can hold the role. Investment discretion can also be handed to a professional who is not the trustee at all, which is how a discretionary trustee compares with hiring a 3(38) investment manager.

The Same Situation, Two Arrangements

A mid-cap fund in your lineup has trailed its benchmark for six straight quarters. The manager who built its track record left last year. Here is how that plays out under each arrangement.

Under a directed trustee

  • Your committee, or the advisor your committee hired, spots the underperformance and puts the fund on watch.
  • Your committee meets, reviews the fund against your investment policy, and decides to replace it.
  • Your committee documents the decision and the reasoning in the minutes.
  • Your committee instructs the trustee to make the change.
  • The directed trustee executes the trade, moves the assets, and keeps the records.

Under a discretionary trustee

  • The trustee spots the underperformance through its own monitoring.
  • The trustee evaluates the fund and selects the replacement.
  • The trustee documents its analysis and makes the change.
  • The trustee reports the change to your committee, on whatever schedule your service agreement sets.
  • Your committee reviews the trustee’s work as part of overseeing the trustee.

Notice what the committee does in each version. 

Under the directed arrangement, the committee does the analysis, makes the call, and owns the decision. Under the discretionary arrangement, the committee’s job is watching the trustee do that work and confirming the trustee is doing it well.

Now suppose the replacement fund performs poorly too. 

Poor performance by itself is not a breach of anyone’s duty, because federal law measures whether the decision was made carefully, not whether it turned out well. But if the choice was made carelessly, the question of who answers for it depends on the arrangement. 

Under the directed arrangement, that question lands on the committee members who made the choice. Under the discretionary arrangement, it lands on the trustee, and the committee’s exposure runs to whether hiring and keeping that trustee was reasonable.

Is a Directed Trustee Still a Fiduciary?

Yes. The word “directed” makes the role sound like pure order-taking, with no responsibility attached. That is not how federal law treats it. The Department of Labor has addressed the question directly: a trustee is always a fiduciary, because control over plan assets is itself a fiduciary function. Hiring a directed trustee does not produce a trustee free of fiduciary duty. Hiring a directed trustee produces a fiduciary with a much shorter list of duties.

What is on the shorter list is holding the assets, following proper instructions, and the care that goes with both.

What is not on the list matters more for your committee. A directed trustee is not the party responsible for whether your fund lineup is prudent. That responsibility sits with the fiduciary giving the directions, no matter how large the institution holding the assets is.

What Does the Difference Mean for Your Liability?

Under a directed arrangement, the fiduciary giving the instructions is responsible for those instructions. If a fund selection was made without the care federal law requires, the committee members who made it answer for the choice, and that responsibility is personal, not corporate.

Under a discretionary arrangement, responsibility for the investment decisions sits with the trustee, because the trustee is the fiduciary making those decisions. What your committee keeps is a duty federal law does not let a sponsor hand off: selecting the trustee prudently and reviewing that selection on a regular schedule.

Which Arrangement Fits Which Plan?

Start with one question: does your committee want to make the investment decisions, or oversee the professional who makes them?

A directed arrangement fits a committee that:

  • Has the time and the investment expertise to choose funds.
  • Runs a working review process already.
  • Wants a professional holding the assets and carrying out decisions the committee intends to keep making.

A discretionary arrangement fits a plan whose sponsor wants a professional fiduciary making the investment decisions and answering for them. That might be because:

  • The committee is stretched thin.
  • The investment expertise sits outside the company.
  • The sponsor wants decision-making risk placed with a specialist.

Neither arrangement is automatically the right one. The question is which one matches how your committee actually works, not which one sounds safer on paper.

Where This Leaves You

Your plan documents tell you how the arrangement is set up today.

Start with the trust agreement, or the trust provisions inside your plan document, and read the section on the trustee’s powers. If the trustee can invest plan assets on its own, the trustee has discretion. If the trustee acts only on instructions, the trustee is directed.

Then read who gives those instructions. It can be your investment committee, and if that committee is made up of your employees, your employees are the ones responsible for the plan’s investment decisions. It can also be an investment manager the plan hired. And a trust agreement can give the trustee discretion over some assets while directing it as to others. If your documents do not give you a clear answer, that is worth resolving with your advisor or counsel rather than assuming.

While you have the documents out, confirm whether your plan still names an individual, an owner or officer from the plan’s early days, as trustee alongside or instead of an institution, because what a person takes on by signing as trustee is a substantial role in its own right.

Plan Sponsor FAQs

Yes. The switch runs through your plan’s documents: the trust agreement is amended or replaced, and the fiduciary designations are updated to match. Choosing the new trustee prudently is your committee’s responsibility in the switch itself.

Not for investment decisions. Your committee gives the instructions, so your committee remains responsible for those instructions. A directed trustee adds professional custody and execution, not protection for the choices your committee makes.

Whoever the plan documents name. That can be the investment committee, and it can also be an investment manager the plan has appointed. Your trust agreement and plan document together identify who holds that role.
