Quick Answer
What is a fiduciary financial advisor?
An Investment Adviser Representative owes a fiduciary duty when providing investment advisory services. A Registered Representative making a brokerage recommendation to a retail customer is subject to Regulation Best Interest at the time of the recommendation. Some professionals act in both capacities; review Form CRS and Form ADV for services, fees, compensation, and conflicts.
What Does Fiduciary Mean in Financial Advising?
The term "fiduciary" comes from the Latin word "fiducia," meaning trust. In the context of financial advising, a fiduciary is someone who is legally and ethically bound to act in your best interest. According to the Department of Labor (DOL) and the Securities and Exchange Commission (SEC), fiduciary advisors must put your financial welfare above their own.
How Is an Investment Adviser Representative Different From a Registered Representative?
Fiduciary Advisor
- legally and ethically required to act in your best interest
- Must disclose material conflicts of interest
- Required to provide ongoing investment advice.
- fee-based or fee-based compensation
- Registered as an Investment Advisory Representative.
Registered Representative (Regulation Best Interest)
- •Required to act in the retail customer's best interest at the time of sale or recommendation
- •Must disclose material fees, costs, conflicts, and capacity as required
- •May receive transaction-based compensation disclosed in applicable documents
- •Is not required to provide ongoing advice unless separately engaged to do so
How Do Fiduciary Advisors Get Paid?
Investment advisory firms may use several compensation models. Each model can create conflicts that should be disclosed and evaluated:
- Assets Under Management (AUM): A percentage of assets managed; rates vary by firm, service level, and account size
- Flat Fee: A set annual or project-based fee regardless of investment size
- Hourly Rate: Charged by the hour for specific advice or planning sessions
Fee-based advisors like Brett R. Henderson earn compensation through a combination of advisory fees and, in some cases, transaction-based compensation for brokerage services. For a complete description of how Brett is compensated across advisory and brokerage services, see our Form CRS and ADV Part 2A.
How Can I Verify if My Advisor Is a Fiduciary?
- Check the SEC's Investment Adviser Public Disclosure (IAPD) database
- Ask for their Form ADV Part 2 (required disclosure document)
- Verify the advisory firm's registration and the professional's Investment Adviser Representative record in IAPD
- Check FINRA BrokerCheck for their background
- Ask them to sign a fiduciary oath in writing
Why Does Fiduciary Duty Matter for Your Retirement?
The difference between fiduciary and non-fiduciary advice can significantly impact your retirement savings. Research from the Department of Labor found that conflicted advice costs Americans approximately $17 billion per year in retirement savings.
"A practical step many investors take is to ask any prospective advisor whether they will act as a fiduciary for the entire engagement and to request the description in writing. A true investment adviser welcomes the question because the Investment Advisers Act of 1940 imposes a fiduciary duty of care and loyalty on the advisory relationship. At SWE90, investment advisory engagements are documented in a written advisory agreement, Form ADV Part 2, and Form CRS that describe our standard of care, fees, and conflicts."

Frequently Asked Questions
What is a fiduciary financial advisor?
An Investment Adviser Representative owes a fiduciary duty when providing investment advisory services. A Registered Representative making a brokerage recommendation to a retail customer is subject to Regulation Best Interest at the time of the recommendation. Some professionals act in both capacities; review Form CRS and Form ADV for services, fees, compensation, and conflicts.
How do fiduciary advisors get paid?
Advisory services may be compensated through hourly, flat, or asset-based fees. Fee-based compensation can reduce some commission-related incentives, but it does not eliminate all conflicts. Review Form ADV Part 2, Form CRS, and the advisory agreement for fees, compensation, and conflicts.
How can I verify if my advisor is a fiduciary?
You can verify fiduciary status by checking the SEC's Investment Adviser Public Disclosure (IAPD) database, asking for their Form ADV Part 2, confirming they are a Registered Investment Advisor (RIA), and asking them directly to sign a fiduciary oath.
What is the difference between an Investment Adviser Representative and a Registered Representative?
An investment adviser representative (IAR) acting in that capacity is held to a fiduciary duty under the Investment Advisers Act of 1940 and must act in the client's best interest. A broker-dealer registered representative is held to FINRA's Regulation Best Interest (Reg BI) when making recommendations to retail customers. The two standards differ in scope, ongoing duty, and disclosure obligations. Review the professional's Form ADV Part 2 (for IARs) or Form CRS (for both) for capacity, fees, and conflicts.
Why should I work with a fiduciary advisor?
Working with an Investment Adviser Representative means the professional owes a fiduciary duty when providing investment advisory services. The professional should explain fees, disclose material conflicts, and provide advice within the agreed advisory scope. Brokerage services are subject to Regulation Best Interest rather than an ongoing advisory duty.
