Fiduciary Duty vs. Suitability: What Your Advisor Owes You
Table of Contents
Key Takeaway: Not all financial advisors are held to the same legal standard. A fiduciary must act in your best interest at all times, while a broker following suitability rules only needs to recommend investments that are “suitable” — even if a better option exists. Knowing which standard applies to your advisor can determine whether you have a claim when something goes wrong.
When you trust someone with your life savings, you assume they’re looking out for you. But the law doesn’t always require that. The standard your financial advisor is held to — fiduciary duty or suitability — defines what they legally owe you, and the gap between the two is wider than most investors realize.
Understanding this distinction isn’t academic. It can be the difference between having a valid claim for your losses and having no recourse at all.
What Is Fiduciary Duty?
A fiduciary duty is the highest legal obligation one party can owe another. It requires a financial advisor to act solely in the client’s best interest, prioritize the client’s financial welfare above their own, and disclose all material conflicts of interest.
Under fiduciary duty, your advisor must:
- Put your interests first — always, without exception
- Disclose all conflicts of interest — including commissions, referral fees, and incentive bonuses
- Provide advice that is in your best interest — not merely acceptable or suitable
- Avoid self-dealing — they cannot profit at your expense
- Seek best execution — they must strive for the most favorable terms reasonably available
The fiduciary standard comes from the Investment Advisers Act of 1940 and has been reinforced by SEC interpretations and court decisions for decades. It is not a gray area. A fiduciary who places their own financial interest ahead of a client’s has violated the law.
What Is the Suitability Standard?
The suitability standard requires a broker to recommend investments that are suitable for the customer based on their profile — but does not require the broker to act in the customer’s best interest.
Under suitability rules, a broker must have a reasonable basis to believe a recommendation is appropriate for a specific customer, considering factors like the customer’s age, income, risk tolerance, investment experience, and financial goals.
But here’s the critical distinction: a suitable investment is not necessarily the best investment. A broker following suitability rules can recommend a product that earns them a higher commission over a lower-cost alternative that would serve you better — as long as the recommended product is technically “suitable.”
Regulation Best Interest (Reg BI)
In June 2020, the SEC implemented Regulation Best Interest (Reg BI), which raised the standard for broker-dealers beyond the old suitability rule. Reg BI requires brokers to act in the “best interest” of the customer at the time a recommendation is made, but it stops short of imposing a full fiduciary duty.
Key limitations of Reg BI:
- It applies only at the time of the recommendation — not as an ongoing duty
- It does not require the broker to monitor the account continuously
- It allows conflicts of interest to persist as long as they are disclosed, not eliminated
- It does not require the broker to choose the lowest-cost option if a more expensive option is also suitable
Critically, Reg BI is not the same as fiduciary duty. It narrows the gap, but it does not close it.

Which Advisors Are Fiduciaries?
The type of advisor you work with determines the legal standard that applies. Here’s how the landscape breaks down:
Registered Investment Advisers (RIAs)
RIAs are firms or individuals registered with the SEC or state securities regulators under the Investment Advisers Act of 1940. RIAs owe a fiduciary duty to their clients. This is a federal obligation enforced by the SEC.
If you work with an RIA, your advisor must:
- Put your interests first at all times
- Disclose and either eliminate or fully mitigate conflicts of interest
- Provide advice that is in your best interest, not merely suitable
- Act with the care, skill, and diligence of a prudent professional
Broker-Dealers
Broker-dealers are regulated by FINRA and the SEC. Following Reg BI, they must act in your “best interest” when making recommendations, but they are not held to a full fiduciary standard.
The practical difference matters:
| Obligation | RIA (Fiduciary) | Broker-Dealer (Reg BI) |
|---|---|---|
| Put client first | Yes — always | At time of recommendation |
| Eliminate conflicts | Must or fully mitigate | Must disclose, not eliminate |
| Ongoing duty | Yes | No — point-of-sale only |
| Monitor account | Required by duty | Not required |
| Lowest-cost option | Must justify if not chosen | Not required |
Insurance Agents
Insurance agents selling fixed annuities, variable annuities, and life insurance products are typically regulated by state insurance departments. Most insurance agents are not fiduciaries and are held only to a suitability standard — and in many states, even that standard is minimal.
Hybrid and Dual Registrants
This is where it gets complicated — and where many investors are caught off guard.
A dual registrant is an advisor who is registered both as an RIA and as a broker-dealer representative. They operate under two different standards depending on which hat they’re wearing at any given moment.
When acting as your RIA, they owe you a fiduciary duty. When acting as your broker, they only owe the Reg BI standard. The problem? Most investors don’t know which role applies to each transaction, and some advisors blur the line deliberately.
Industry data suggests that over 50% of financial advisors hold dual registrations. If your advisor is dually registered, ask them — in writing — which standard applies to each recommendation they make.

The Gap Between Fiduciary Duty and Suitability
The difference between these two standards is not theoretical. It can cost you real money.
Consider this scenario: You’re a 62-year-old investor approaching retirement with moderate risk tolerance. Your advisor recommends a variable annuity with a 2.5% annual fee and a 7-year surrender charge. A low-cost index fund portfolio would cost 0.10% annually with no surrender penalties.
Under the suitability standard, this recommendation may be defensible — the annuity is technically “suitable” for someone approaching retirement who wants guaranteed income features.
Under the fiduciary standard, this recommendation likely violates the duty — the advisor cannot justify placing you in a dramatically more expensive product with lock-up penalties when a significantly better alternative exists.
That gap — between what’s “suitable” and what’s best — is where billions of dollars in investor losses occur each year. According to a 2023 study by the Council of Economic Advisers, conflicts of interest in financial advice cost retail investors an estimated $17 billion per year in excess fees and underperformance.
How to Tell Which Standard Applies to Your Advisor
You don’t have to guess. Here are concrete steps to determine your advisor’s legal obligations:
-
Check their registration. Use the SEC’s Investment Adviser Public Disclosure (IAPD) website at adviserinfo.sec.gov or FINRA’s BrokerCheck at brokercheck.finra.org. If they’re registered as an RIA, they owe you a fiduciary duty. If they’re only registered as a broker-dealer, they owe Reg BI.
-
Review your advisory agreement. The contract you signed should specify whether the relationship is advisory (fiduciary) or brokerage (Reg BI/suitability). If the language is unclear, that’s a red flag.
-
Ask directly. Ask your advisor: “Are you a fiduciary? Will you act in my best interest at all times?” If they hedge, qualify, or say “it depends,” they likely are not a fiduciary in that capacity.
-
Look at how you pay. Fee-only advisors (who charge a flat fee or percentage of assets) are typically fiduciaries. Commission-based brokers are typically not. Fee-based advisors (who charge fees AND earn commissions) may be dual registrants.
-
Check for disclosures. Your advisor’s Form CRS (Client Relationship Summary) — required by the SEC — must disclose whether they are a fiduciary, what conflicts of interest exist, and whether they earn commissions.
When a Violation Gives You a FINRA Arbitration Claim
Regardless of which standard applies, a violation can give you grounds for a claim. Here’s how it works:
Fiduciary Breach Claims
If your RIA breaches their fiduciary duty, you may file a claim through:
- FINRA arbitration (if the RIA is a FINRA member or the agreement requires it)
- SEC enforcement action (for systemic violations)
- State court (for claims under state fiduciary duty law)
Common fiduciary breaches include recommending high-fee products when lower-cost alternatives exist, failing to disclose conflicts of interest, churning an account for commissions, and placing the advisor’s financial interest ahead of the client’s.
Suitability and Reg BI Violation Claims
If your broker violates the suitability standard or Reg BI, you can file a FINRA arbitration claim. Common violations include recommending unsuitable products based on your risk profile, failing to conduct reasonable diligence on a recommendation, recommending a product without a reasonable basis, and failing to disclose material conflicts of interest.
Under FINRA Rule 2111, a broker must have a reasonable basis to believe that a recommended transaction or investment strategy is suitable for the customer. This includes reasonable-basis suitability (the product must be suitable for some investors), customer-specific suitability (the product must be suitable for this particular customer), and quantitative suitability (the broker must not recommend excessive trading).

Why the Distinction Matters for Your Claim
The standard your advisor owes you doesn’t just affect whether a violation occurred — it affects how your claim is evaluated and what you can recover.
Fiduciary breach claims are generally stronger. The fiduciary standard is objective: either the advisor put your interest first, or they didn’t. Courts and arbitrators don’t need to debate whether a product was “suitable enough.” They ask whether the advisor acted with undivided loyalty.
Suitability claims can be harder to prove. The broker only needs to show that the investment was appropriate for someone with your profile — not that it was the best option. This gives brokers more room to defend their recommendations.
However, under Reg BI, the burden may be shifting. If a broker recommends a high-commission product when a clearly better alternative exists, the “best interest” language may give arbitrators more latitude to find a violation.
Damages You May Recover
If your claim succeeds, you may recover:
- Compensatory damages — the amount you lost due to the violation
- Rescission — return of the investment, with the advisor absorbing the loss
- Attorneys’ fees — in some cases, particularly in fiduciary breach claims
- Disgorgement — return of ill-gotten profits the advisor earned
According to FINRA data, the average award in customer-broker disputes in 2023 was approximately $168,000, though individual recoveries vary significantly based on the specifics of each case.
Protecting Yourself: Know the Standard Before You Invest
The best protection is knowing what your advisor owes you before a problem arises. Here are steps every investor should take:
- Verify your advisor’s registration using BrokerCheck and IAPD
- Read Form CRS and ask questions about anything unclear
- Get it in writing — ask your advisor to confirm whether they are a fiduciary for your account
- Review your account statements for investments that seem inconsistent with your goals
- Ask about fees and commissions on every recommendation
- Document everything — keep records of all communications with your advisor
If you suspect your advisor has violated the standard they owe you — whether fiduciary or suitability — don’t wait. Time limits apply to all investment fraud claims, and delaying can cost you the right to recover.

Frequently Asked Questions
Is my financial advisor a fiduciary?
It depends on their registration. Registered Investment Advisers (RIAs) are fiduciaries under the Investment Advisers Act of 1940. Broker-dealers are held to the Regulation Best Interest (Reg BI) standard, which is less stringent. You can check your advisor’s registration at brokercheck.finra.org or adviserinfo.sec.gov. Ask your advisor directly and get their answer in writing.
What is the difference between fiduciary duty and suitability?
Fiduciary duty requires an advisor to act in your best interest at all times, put your interests ahead of their own, and disclose or eliminate all conflicts of interest. Suitability requires only that an advisor recommend investments appropriate for your profile — even if a better, lower-cost option exists. The fiduciary standard is significantly more protective of investors.
Can a broker be a fiduciary?
A broker-dealer representative can also be registered as an RIA, in which case they are a fiduciary when acting in their RIA capacity. However, when acting as a broker, they are held only to the Reg BI standard. Dual registrants switch between standards depending on the role they’re performing, which can create confusion about their obligations. See our post on When Can You Sue Your Financial Advisor? for more on how this affects your rights.
What should I do if I think my advisor violated their duty?
Gather your account statements, trade confirmations, and any written communications with your advisor. Then contact an investment fraud attorney who can evaluate whether the advisor violated the applicable standard — fiduciary or suitability — and whether you have a viable claim. Time limits apply, so it’s important to act promptly. Call 1-888-885-7162 for a free consultation.
How much can I recover in a fiduciary breach or suitability claim?
Recovery depends on the specifics of your case, including the amount you lost, the nature of the violation, and the standard that applies. In fiduciary breach claims, you may recover compensatory damages, rescission, and in some cases attorneys’ fees. According to FINRA data, the average award in customer-broker disputes in 2023 was approximately $168,000. However, past results do not guarantee future outcomes.
Does Regulation Best Interest (Reg BI) make brokers fiduciaries?
No. Reg BI raised the standard for brokers from suitability to “best interest” at the time of a recommendation, but it is not equivalent to fiduciary duty. Reg BI does not require brokers to eliminate conflicts of interest — only to disclose them. It does not impose an ongoing duty to monitor accounts. The fiduciary standard under the Investment Advisers Act remains the higher and more protective standard.
