“Fiduciary” is the most load-bearing word in financial advice, because it answers the only question that matters about anyone touching your money: are they legally required to put your interests first — or merely forbidden from selling you something outright unsuitable? Those are different standards, and the industry is built in the gap between them.
The standard, plainly
A fiduciary must act in your best interest: put your outcome ahead of their compensation, disclose conflicts, and choose the better option for you even when the worse one pays them more. SEC-registered investment advisers (the RIAs whose Form ADV we teach you to read here) owe this duty by law. Brokers historically owed only “suitability” — the product had to fit, not to be best — a bar raised somewhat by Regulation Best Interest in 2019, but still not the full fiduciary standard, and insurance sales often sit under looser rules again (why that matters).
Why the label alone isn’t enough
Two complications. Dual registrants: many firms are both adviser and broker, wearing the fiduciary hat on some accounts and the sales hat on others — same person, different legal duties depending on which paper you signed. And fiduciary-with-conflicts: the duty requires disclosing conflicts, not eliminating them; an RIA can still favor affiliated funds if the ADV says so. The word is the start of diligence, not the end of it.
The questions that settle it
Ask, in writing: “Are you a fiduciary on this account, at all times, for all recommendations?” Then: “How exactly are you paid?” Fee-only (paid by you, nothing from products) is the cleanest answer; fee-based means commissions too — one syllable hiding the whole difference. Then verify the registration itself — adviser at adviserinfo.sec.gov, broker at brokercheck.finra.org, or a Verifier scan — because a fiduciary claim from an unregistered entity isn’t a lower standard, it’s a fiction. Robo-advisors, for the record, are RIAs and owe the duty too; the question there is value, not loyalty.
