Most people assume a trust is straightforward: you set it up, name beneficiaries, and the plan runs on autopilot.
In reality, a trust is less like a “set it and forget it” account and more like a long-term operating manual. And one question often shapes how smoothly it works over time:
Who actually has the authority to make decisions?
That answer affects everything from investment changes to distribution requests to how family expectations are managed.
The Two Key Roles: Trustee and Financial Advisor
In many trust relationships, two parties are central to day-to-day outcomes:
- The trustee (the decision-maker responsible for administering the trust)
- The financial advisor (the investment professional supporting the trust’s strategy)
They may collaborate closely—but they do not always have the same authority.
The Real Job of a Trustee
A trustee’s role is broader than many people realize. Depending on the trust document, the trustee may be responsible for:
- Following the trust’s terms and intent
- Safeguarding and administering trust assets
- Making decisions on distributions to beneficiaries
- Balancing competing interests (for example, current income needs vs. long-term growth)
- Working with professionals (investment, tax, legal) when needed
Trustees typically operate under a fiduciary duty, meaning they must act in the best interests of the parties they serve (generally the beneficiaries and the trust’s stated purpose), not in their own personal interest.
That fiduciary standard is one reason trust decision-making can feel more formal than decisions made in an individual brokerage account.
The Role of the Financial Advisor
A financial advisor working with a trust generally focuses on the investment side, such as:
- Building an allocation aligned with the trust’s goals
- Managing risk in the context of time horizon and liquidity needs
- Monitoring the portfolio and making recommendations
- Coordinating investment strategy with tax considerations (often in partnership with a CPA)
But here is the point that often surprises families:
An advisor may recommend, but not always decide.
Whether the advisor can implement changes directly depends on how the trust is structured and who holds investment authority.
The Standard That Guides Investment Decisions: The Prudent Investor Rule
Many trustees and trust advisors operate with a framework often referred to as the Prudent Investor Rule. While the details can vary by state and the trust’s language, the general concept is consistent:
Investment decisions should be made with:
- Care
- Skill
- Discipline
- A focus on the trust’s long-term purpose
This standard often emphasizes:
- Diversification (when appropriate)
- Risk management relative to the trust’s objectives
- Ongoing review and monitoring rather than one-time decisions
Importantly, this is usually not about judging a single investment in isolation. It’s about whether the overall strategy is reasonable given the trust’s goals and constraints.
It’s Not About One Holding—It’s About the Whole Strategy
A common misconception is that trust investing is about finding the “best” investment.
In a fiduciary context, the more relevant question is typically:
Does the overall plan support what the trust is designed to do?
For example, two trusts could invest very differently based on factors like:
- The time horizon (a beneficiary who is 12 vs. 62)
- The need for income vs. long-term growth
- Anticipated distributions (regular support payments vs. future lump sums)
- The trust’s tax profile and administrative requirements
This is why process often matters as much as outcomes. A well-documented, goal-based strategy can help reduce confusion when markets are volatile.
Not All Trusts Work the Same Way
The phrase “the trustee is in charge” is often true—but not always. Two common structures illustrate why:
1) Discretionary Trust
In a discretionary trust, the trustee typically has broad authority. The trustee may decide:
- When and how much to distribute (within the trust terms)
- Whether to accept or decline beneficiary requests
- Which investment recommendations to approve
The advisor provides guidance, analysis, and recommendations, but the trustee generally retains final decision-making control.
2) Directed Trust
In a directed trust, investment authority may be assigned to someone other than the trustee (often called an “investment director” or similar role). Depending on the document and state law, that authority could sit with:
- The person who created the trust (in some structures)
- A family member or committee
- A specialized professional
In this setup, the trustee may be required to follow the investment directions given—changing the working relationship and the workflow for decisions.
Why Decision Authority Matters in Real Life
When families aren’t clear on who decides, confusion can show up quickly. For example:
- A beneficiary asks the advisor for a distribution, assuming the advisor can approve it.
- The advisor explains they don’t have authority.
- The trustee must review the request, consider the trust terms, and decide.
That gap between expectations and authority can create frustration—especially during stressful moments (a job loss, medical expense, market downturn, or family conflict).
A clear understanding upfront helps everyone know:
- Who can say “yes” or “no”
- What process will be followed
- What information is needed to make a decision
One of the Hardest Topics: Concentrated Positions and Diversification
Diversification can become especially sensitive when a trust contains a large holding in:
- A single stock
- A family business interest
- A legacy asset with emotional significance
Families may feel attached to the asset because it represents the original source of wealth or a family story.
At the same time, a trustee often has a duty to consider risk. Even when the trust permits holding a concentrated position, the trustee may still need to evaluate questions like:
- What could happen if this asset declines significantly?
- Does the trust need liquidity over a certain period?
- Is the concentration consistent with the trust’s purpose and beneficiary needs?
These are rarely easy conversations, but they are often necessary.
Documentation: The Quiet Protector
In trust administration, documentation matters. A disciplined record of decisions can help demonstrate that actions were thoughtful and aligned with the trust’s purpose.
Good documentation may include:
- The trust’s objectives and constraints
- Meeting notes and rationale for changes
- Investment policy guidelines (formal or informal)
- A record of distribution considerations
This isn’t just paperwork. When markets are volatile or beneficiaries have questions, documentation can help everyone understand the “why” behind decisions.
“Who Is the Client?” (It’s Not Always Who You Think)
Trusts can involve multiple stakeholders:
- The person who created the trust
- One or more trustees
- Multiple beneficiaries
- Family members with strong opinions
From a decision-making standpoint, the “client” for investment authority is generally the person (or entity) empowered by the trust and account registration—often the trustee, or an appointed investment decision-maker in a directed trust.
Clarifying this early can prevent misunderstandings and keep communications aligned.
The Best Outcomes Come From Coordinated Teamwork
Trusts tend to work best when the right people are collaborating:
- Trustee (administration, fiduciary oversight, distributions)
- Financial advisor (portfolio strategy, monitoring, risk management)
- Tax professional (trust taxation and planning)
- Estate planning attorney (trust language, roles, and updates over time)
When everyone understands their roles and communicates effectively, decisions are clearer, errors are less likely, and the trust is more likely to function as intended.
Final Thought
A trust is not just about transferring money. It’s about ongoing decisions, responsibility, and protecting people over time.
If you have a trust in place—or you serve as a trustee—one of the most valuable first steps is simply confirming: Who has decision-making authority, and what process will guide those decisions?
