What is a fiduciary — and what doesn’t it protect you from?
It’s the industry’s magic word. People wield it in forums like a password — “the word of the day is fiduciary” — while the people who most need it quietly ask what it means. Here’s the plain-English version, including the part the pamphlets leave out: the word’s limits.
Consumer education, not investment advice. Paul Powell is not currently a licensed financial advisor.
A fiduciary is legally required to put your interests ahead of their own — the highest standard of care the law offers. It matters enormously. And it is not a force field: a fiduciary can still be dually registered, still switch hats mid-meeting, still charge a percentage of your assets, and still be mediocre. The word is where your questions start — not where they end.
Three standards, one ladder
Everyone who gives financial advice is held to some legal standard. There are three, and the entire game is knowing which one applies to the person across the desk — because the title on the business card doesn’t tell you.
Suitability — the old floor. The product only had to be “suitable for someone like you.” Not best. Not cheapest. Just defensible on a form.
Best interest — the current broker standard. Regulation Best Interest (2020) raised brokers above suitability, and it sounds like fiduciary on purpose. It isn’t: commissions are still allowed, conflicts are handled mostly by disclosure, and the duty attaches to each recommendation, not to the relationship.
Fiduciary — the top rung. Registered investment advisers (RIAs) owe you this duty under the law: your interests first, conflicts disclosed and managed, loyalty and care owed to you. When people say “find a fiduciary,” this is what they mean — and as far as it goes, they’re right.
The four limits nobody explains
Limit one: the two hats. Many advisors are dually registered — an RIA fiduciary when “advising,” a commissioned broker when “selling.” Same person, same meeting, two standards. The fiduciary duty covers the advisory account; the annuity pitch that follows may not be under it. Even the CFP letters don’t settle this — CFP Board’s standard is real, but a dually registered CFP can still earn commissions on products.
Limit two: fiduciaries charge fees too. The duty governs loyalty, not price. A fiduciary can charge a percentage of your assets — with the gathering conflict that structure carries — and remain a fiduciary in good standing. “Fee-only fiduciary” is better than most alternatives. It is not the same as cheap, and not the same as conflict-free.
Limit three: fiduciary ≠ competent. The duty is about whose interests come first — not about skill. A fiduciary can be honest, loyal, and mediocre. The credentials, the track record, the process — you still have to check all of it.
Limit four: the word is spoken more than it is signed. “I always act in my clients’ best interest” is a slogan. The legal standard shows up in the paperwork — the Form ADV, the advisory agreement — or it doesn’t exist. If it’s true, it costs nothing to confirm in writing. If they won’t write it, you have your answer.
The worst position isn’t hiring a non-fiduciary. It’s hiring anyone because they said the word. “Are you a fiduciary?” asked out loud, answered out loud, ends with “yes” every time — the word has been marketing since the day consumers learned to ask for it. The protection was never the word. The protection is the written, at-all-times, every-account confirmation — and the public file that lets you check it.
Get the word in writing — then keep asking questions
This is Question 1 of the 12, and it’s first for a reason:
“Are you a fiduciary — legally required to act in my best interest — 100% of the time, on every account and every recommendation? Will you confirm that in writing?”
The answer you want is one word — “always” — with a signature under it. Then verify: pull their Form ADV, where the registration, the compensation, and the conflicts are disclosed in the public record. Five minutes, free, and it tells you which hats the person actually wears.
Then remember what the word can’t do, and keep going: the fee question, the conflict question, the benchmark question. A fiduciary who welcomes all twelve in writing is the real thing. The word opens the door. The paper walks through it.
