What Is a Fiduciary, and Why Does It Matter?

How do you know whether the person advising you is required to put your interests first? It is a fair question, and the answer is not always obvious from a title or a business card. The word fiduciary is the key, and it is worth understanding precisely, because it describes a legal obligation rather than a marketing claim.

What a fiduciary is

A fiduciary is someone legally obligated to act in another person's best interest, placing that person's interests ahead of their own. The concept is old and applies in many settings: a trustee managing assets for beneficiaries, an executor settling an estate, an attorney representing a client.

In financial advice, an investment adviser (a firm or individual registered to provide advice about securities for compensation) owes a fiduciary duty to clients. That duty is generally understood to have two parts. A duty of care means giving advice suited to the client's circumstances, based on a reasonable understanding of them. A duty of loyalty means avoiding conflicts of interest where possible and fully disclosing those that remain, so the client can make an informed decision.

A fiduciary standard does not ensure good advice. It determines whose interest the advice is supposed to serve.

Fiduciary versus suitability

Not everyone who offers financial guidance is a fiduciary. Brokers, who buy and sell securities on behalf of customers and are typically paid per transaction, have historically operated under a different standard, often called suitability. Under that standard, a recommendation had to be appropriate for the customer's situation, but it did not have to be the option that served the customer best.

The difference can be subtle in practice. Suppose, for illustration, two investment products are both reasonable for a particular person, but one pays the person recommending it a substantially higher commission. Under a suitability standard, recommending the higher-commission product is generally permissible, because it is suitable. Under a fiduciary standard, the adviser must either recommend the option that better serves the client or disclose the conflict clearly enough for the client to weigh it.

The rules governing brokers have evolved, and current regulations generally require them to act in a customer's best interest at the time of a recommendation and to address conflicts. Even so, the obligations are not identical to the fiduciary duty that applies to investment advisers, and the standards continue to be debated and revised. Many professionals are registered in both capacities and may act under different standards depending on the service provided. Which role someone is acting in at a given moment is a reasonable thing to ask.

How advisers are paid, and why it matters

Compensation shapes incentives, so how an adviser is paid sits close to whose interest the advice serves. Three models are common.

Fee-only advisers are paid solely by their clients, whether as a percentage of assets managed, a flat or hourly fee, or a retainer. They receive no commissions or payments from product providers. This does not eliminate every conflict, since an adviser paid on assets has an interest in those assets growing and staying under management, but it removes the incentive to favor one product over another.

Commission-based professionals are paid by the companies whose products they sell, through commissions, sales charges or ongoing payments. The client may pay nothing directly, but the cost is built into the product, and the professional's income depends on what is sold.

Fee-based advisers, a term easily confused with fee-only, may charge fees for advice and also receive commissions on some products. This hybrid arrangement varies widely, and the distinction between fee-only and fee-based is among the most commonly misunderstood in the field.

None of these models is inherently improper, and none ensures good advice. But each creates a different set of incentives, and knowing which one applies helps you interpret what you are told.

What the public disclosures contain

Registered investment advisers must file public disclosure documents with securities regulators, and anyone can read them.

Form ADV is the primary filing. Its first part covers the firm's business, ownership, size, types of clients, disciplinary history and conflicts of interest. Its second part, written in plain language, describes the services offered, the fees and how they are calculated, the investment approach, and the conflicts the firm has identified and how it manages them. A supplement describes the background and qualifications of the individuals who give advice.

Form CRS, a short relationship summary, is designed for individual investors and answers a standard set of questions: what services are offered, what fees and costs apply, what conflicts exist, whether the firm or its professionals have a disciplinary history, and where to find more information. It also includes a list of questions investors are encouraged to ask.

Reading these documents before an engagement, or asking an adviser to walk through them with you, is a well-spent hour. The direct questions below need no filing at all, and a professional who answers them plainly is telling you something valuable. Where a question turns on the legal structure of a trust or estate, or on a specific tax matter, a qualified attorney or tax professional belongs in the conversation as well.

Questions to Discuss With Your Advisor

• Are you a fiduciary in every part of our relationship, or only for certain services?
• How exactly are you compensated, and does any of it come from third parties?
• What conflicts of interest are described in your Form ADV and Form CRS, and how do you manage them?
• Do you or your firm have any disciplinary history I should know about?
