What Is a Fiduciary Financial Advisor?

A fiduciary is a person or entity that is legally required to act in the interest of another party. In the investment context, the fiduciary duty of an investment adviser comes from the Investment Advisers Act of 1940, as interpreted by the SEC and courts over decades. Registration as an investment adviser does not just grant a title. It attaches a legal obligation.

The duty has two components. The first is the duty of care. An adviser must provide advice that is in the client's best interest, based on the client's individual situation. Generic advice that happens to benefit the adviser does not meet this standard. The second is the duty of loyalty. An adviser must put the client's interest ahead of their own. When a conflict exists between what is good for the client and what is good for the adviser's business, the client comes first. Any material conflict that the adviser cannot eliminate must be disclosed in writing, in advance, in Form ADV Part 2A.

Together, these duties mean that a fiduciary investment adviser cannot recommend a product primarily because it pays the adviser more than the alternative. They cannot hold client assets in a way that benefits the firm at the client's expense. They cannot hide relationships with third parties that affect what they recommend. None of that makes an adviser immune to bad judgment or poor outcomes. Investing involves risk, and fiduciary duty does not guarantee results. What it does guarantee is that the legal obligation runs to the client, not to a commission schedule or a parent company.

Investment advisers registered under the Investment Advisers Act of 1940 are fiduciaries. This covers registered investment advisers (RIAs) registered with the SEC or with a state securities regulator. The fiduciary duty applies to the full scope of the advisory relationship, not just at certain transactions. A state-registered adviser like Narstar owes that duty continuously, from the moment the advisory agreement is signed through every portfolio decision made afterward.

Broker-dealers and registered representatives are not subject to the same fiduciary standard. They operate under a different regulatory framework, discussed in the next section. The distinction matters because many firms hold both registrations and a client may be dealing with either one depending on the service being performed.

Fee-only investment advisers are typically pure RIAs with no broker-dealer affiliation. A fee-only adviser who holds no broker-dealer registration cannot flip into a lower standard for any particular transaction. Fee-based advisers often hold both registrations. They may owe fiduciary duty when acting in their advisory capacity and a lower standard when acting as a broker. The standard that applies depends on what the adviser is doing at that moment. This is legal and disclosed in Form ADV. It is also genuinely confusing for clients who assume the fiduciary label applies uniformly. If you want to understand how each structure handles compensation, the fee-only vs. fee-based article goes into more detail.

Regulation Best Interest (opens in new tab), often called Reg BI, requires that broker-dealers act in the best interest of a retail customer at the time of a specific recommendation. That is a meaningful improvement over the previous "suitability" standard, which only required that a recommendation be appropriate for the customer's situation, not necessarily the best option available. But Reg BI is not the same as the fiduciary duty that applies to investment advisers.

The key differences come down to timing and ongoing obligation. Fiduciary duty is continuous. An investment adviser owes a duty of loyalty throughout the advisory relationship. If a conflict of interest arises that was not disclosed upfront, the adviser must disclose it as soon as it becomes material, not wait for the next transaction. Reg BI applies at the transaction level. A broker meets the standard if each individual recommendation, at the moment it is made, is in the customer's best interest. There is no ongoing duty between transactions.

The disclosure requirements also differ. An investment adviser must disclose material conflicts in Form ADV Part 2A before the advisory relationship begins, and keep those disclosures current. A broker discloses conflicts at the point of recommendation through the relationship summary, or Form CRS. The practical result is that a fiduciary investment adviser and a broker operating under Reg BI may look similar from the outside. Both are using the language of "best interest." The legal obligations are different, and so are the consequences when something goes wrong.

First, look up the adviser on the SEC's Investment Adviser Public Disclosure system at adviserinfo.sec.gov (opens in new tab). Search by name or CRD number. A pure investment adviser will show registration as an RIA without a parallel broker-dealer registration. If the record shows dual registration as both an investment adviser and a broker-dealer, the adviser wears both hats and the standard that applies may vary by transaction.

Second, read Form ADV Part 2A. It describes the advisory services the firm offers, compensation structure, any affiliations with broker-dealers or other financial industry firms, and disciplinary history. If the disclosures mention services provided in a non-advisory capacity, the adviser has told you directly that fiduciary duty does not always apply. Each Form ADV is a public document. Mine is linked from the footer of every page on this site. You can also check the individual adviser's record on FINRA BrokerCheck (opens in new tab), which shows employment history, licenses, and any disclosure events for both broker-dealer representatives and investment adviser representatives.

Third, ask the adviser directly: "Are you a fiduciary for every service you provide to me?" The right answer for a pure investment adviser is yes, always. There are other questions worth asking before you hire anyone, and fiduciary status is just the first one. If the answer involves any qualification, you now know what you are dealing with. One more note: fiduciary status does not mean the adviser is free of all conflicts. An adviser charging a percentage of assets still has an incentive to grow the account rather than recommend other uses for the money. Those remaining conflicts are required to be disclosed in Form ADV. For our disclosures, see our about page. Narstar manages three model portfolios (Income, Growth, and Speculative), each with a different approach to risk and volatility.
