What makes an advisor a fiduciary, and why it matters

A fiduciary is a financial advisor who is legally required to put your interests ahead of their own profit. This is different from an advisor who only has to recommend "suitable" products — a suitability standard lets them recommend something that works for you even if they make more money from it. A fiduciary cannot do that. They must recommend what is best for you, even if it costs them a commission or a sale.

The difference shows up in real situations. A non-fiduciary advisor can steer you toward a mutual fund that charges higher fees because their firm gets a bigger cut. A fiduciary cannot, even if the fund is technically suitable for your goals. A fiduciary must disclose what they earn from each recommendation and explain why they chose it over cheaper alternatives.

Not all financial advisors are fiduciaries all the time. Some are fiduciaries only when they manage your retirement account (like an IRA), but not when they sell you insurance or other products. Others are fiduciaries for everything they do. Knowing which type you are dealing with changes what questions to ask and what disclosures to demand.

Key Takeaways

  • Fiduciaries must put your interests first by law; non-fiduciaries only have to recommend something "suitable" even if it pays them more.
  • Ask an advisor directly whether they are a fiduciary for all services they provide, and get the answer in writing before you hire them.
  • Check the SEC's Investment Adviser Public Disclosure database or FINRA's BrokerCheck to see what licenses an advisor holds and whether they have disciplinary history.
  • Fee-only advisors (who charge you directly rather than earning commissions) are always fiduciaries, while commission-based advisors may not be.
  • Request a written statement of how the advisor is compensated for each product or service they recommend to you.

Ask the advisor directly about their fiduciary status

The simplest way to find out is to ask. Call or email and say: "Are you a fiduciary for all the services you provide to me, or only for some?" Write down the answer. If they say "only for retirement accounts" or "only for investment management," that is useful information — it tells you they are not a fiduciary when they sell you insurance, annuities, or other products.

If they say yes to everything, ask them to put it in writing. A legitimate fiduciary will send you a document that states their fiduciary status and when it applies. If they hesitate, dodge the question, or say "we're fiduciaries when required by law," that is a red flag. A true fiduciary does not need to may have access to the answer.

Do not rely on a website claim alone. Websites can say anything. The written commitment you get before you sign an agreement is what matters legally. Some advisors will include this in their Form ADV (the disclosure document all registered investment advisors must file with the SEC), and some will put it in a separate letter. Either way, you should have it before you hand over money.

Check the SEC and FINRA databases for licenses and history

The SEC maintains the Investment Adviser Public Disclosure database at investor.gov. Type in the advisor's name or their firm's name. This tells you whether they are registered as an investment adviser, what licenses they hold, and whether they have any disciplinary actions on record. A registered investment adviser is required to be a fiduciary for investment management services.

FINRA (the Financial Industry Regulatory Authority) runs BrokerCheck at brokercheck.finra.org. This is where you look up brokers and brokerage firms. A broker is different from an investment adviser — brokers sell securities and are held to a suitability standard, not a fiduciary standard, unless they are also registered as advisers. BrokerCheck shows you licenses, employment history, and any complaints or disciplinary actions.

Read both reports carefully. Look for the word "investment adviser" in the SEC database — that designation means fiduciary duty. In BrokerCheck, look at what licenses the person holds. Series 7 (general securities), Series 65 (investment adviser), and Series 66 (investment adviser) are common. A Series 65 or 66 means they can act as an investment adviser and owe you fiduciary duty. Check the disciplinary section in both databases. A few minor issues may not disqualify someone, but a pattern of complaints or customer disputes is worth investigating further.

Understand the difference between fee-only and commission-based compensation

A fee-only advisor charges you directly — either a flat fee, an hourly rate, or a percentage of the assets they manage for you. They do not earn commissions from the products they recommend. Because they have no incentive to push one product over another, they are always fiduciaries. Fee-only is the clearest way to avoid conflicts of interest.

A commission-based advisor earns money when you buy a product. They sell you a mutual fund, insurance policy, or annuity, and they get paid a percentage of what you invest. This creates a conflict: they earn more if they recommend the higher-commission product, even if a lower-commission option would serve you better. Commission-based advisors are not required to be fiduciaries unless they are also registered as investment advisers.

Some advisors use a hybrid model: they charge you a fee for some services and earn commissions on others. This is legal, but it creates multiple conflicts. Ask them to break down exactly how much they earn from each recommendation. If they cannot or will not, that is a reason to look elsewhere. A fiduciary in a hybrid arrangement must disclose all compensation sources and explain why they chose each product despite the commission they earn.

Request a written compensation disclosure

Before you hire an advisor, ask them to provide a written statement showing how they are compensated for every service and product they might recommend to you. This should include their fee structure, any commissions they earn, and any other payments they receive from product providers or their firm.

A good disclosure will say something like: "We charge 1% annually on assets under management. We also earn a 1% commission when you purchase a mutual fund through us. We do not earn a commission on index funds." This tells you exactly where the conflicts are. If an advisor says "we earn standard industry commissions" without specifying the amounts, ask them to name the actual percentages for the products they recommend most often.

Keep this document. If a dispute arises later, you will have proof of what you were told. Some advisors will include this in their Form ADV Part 2 (the brochure they must give you), and some will provide a separate letter. Either way, you should have it in writing before you sign an investment agreement.

Verify credentials and certifications

Credentials like CFP (Certified Financial Planner), CFA (Chartered Financial Analyst), and CPA (Certified Public Accountant) mean the advisor has passed exams and met education requirements. These are real credentials issued by recognized organizations. They do not may provide fiduciary status, but they do show the advisor has studied financial planning or investment management formally.

Be cautious of credentials you have not heard of. Some firms create their own titles that sound official but mean nothing. Look up any credential on the issuing organization's website. The CFP Board, CFA Institute, and AICPA all maintain registries where you can verify whether someone actually holds the credential they claim.

Credentials matter less than fiduciary status, but they are one signal of professionalism. An advisor with CFP and fiduciary status is generally a safer choice than one with neither. However, a fiduciary without fancy credentials is better than a credentialed advisor who is not a fiduciary.

Ask about conflicts of interest and how they handle them

Even fiduciaries have conflicts of interest. They may earn more from one product than another, or their firm may push certain investments. The difference is that a fiduciary must disclose these conflicts and manage them in your favor. Ask: "What conflicts of interest do you have, and how do you handle them?"

A good answer will name specific conflicts and explain how they mitigate them. For example: "We earn higher commissions on annuities than on index funds, so we have a conflict. We handle it by recommending annuities only when they solve a specific problem you have, and we always show you the index fund alternative and explain why we chose the annuity despite the higher commission." A bad answer will deny having any conflicts or say "we manage conflicts the way the industry does."

Ask whether the advisor or their firm has any business relationships with product providers. If they own part of an insurance company or have a referral arrangement with a brokerage firm, that is a conflict. It is not necessarily disqualifying, but you need to know about it and understand how it affects their recommendations.

Frequently Asked Questions

Can an advisor be a fiduciary for some things but not others?

Yes. An advisor might be a fiduciary when managing your IRA but not when selling you life insurance. Ask them to specify which services carry fiduciary duty and get it in writing. This is common and legal, but you need to know the boundaries so you understand what protections explore to each recommendation.

Does being a fiduciary mean an advisor cannot make mistakes?

No. A fiduciary can recommend something that turns out poorly. Fiduciary duty means they must act in your best interest based on the information available at the time, disclose conflicts, and explain their reasoning. It does not may provide good outcomes. If you believe an advisor violated their fiduciary duty, you may have grounds for a complaint, but poor performance alone is not a violation.

What should I do if an advisor refuses to confirm their fiduciary status in writing?

Find a different advisor. A legitimate fiduciary will put their status in writing without hesitation. If someone avoids the question or says they will only confirm it verbally, that is a sign they may not be trustworthy or may not understand their own obligations. There are plenty of advisors who will give you a clear written answer.

Is a fee-only advisor always better than a commission-based advisor?

Fee-only advisors have fewer conflicts of interest because they do not earn commissions. However, a commission-based advisor who is also a fiduciary and discloses all conflicts can still serve you well. The key is transparency. Know how they are paid, understand the conflicts, and verify they are a fiduciary for all services they provide to you.

What if I find a disciplinary action against an advisor in BrokerCheck or the SEC database?

Read the details. A single customer complaint from years ago may not be significant, but a pattern of complaints or a serious violation (like fraud or theft) is a reason to look elsewhere. You can also contact your state's securities regulator to ask whether they have additional information about the advisor or firm.
