5 Questions to Ask Your Financial Advisor About Fiduciary Duty

Most people don't know whether their financial advisor is legally obligated to put their interests first. That's a problem. The difference between a fiduciary and a suitability standard can cost you thousands in hidden fees and conflicted recommendations.

Why Fiduciary Duty Actually Matters

Here's the gap: under the suitability standard, an advisor just needs to recommend products that aren't totally wrong for you. Under fiduciary duty, they have to recommend what's actually best for your situation.

That's not a small difference. An advisor earning a 5% commission on a loaded mutual fund might sleep fine recommending it under suitability rules. A fiduciary can't, even if the commission is tempting.

Real math example: if you have $500,000 to invest, a suitability advisor might recommend a fund with a 2% expense ratio that pays them a 1% finder's fee. Over 20 years, that's roughly $200,000 more in fees than a 0.5% fiduciary option. The advisor gets paid. You get lighter.

The stakes are real. Before you hand over your money, you need to know which standard your advisor operates under—and whether they mean it.

Question 1: Are You a Fiduciary 100% of the Time, or Only in Certain Contexts?

This is the question that separates the real fiduciaries from the pretenders. Get the answer in writing.

Some advisors are fiduciaries only when they're providing retirement advice. For everything else—brokerage accounts, insurance products—they drop back to suitability. That's not the full protection you're looking for.

Others claim fiduciary status only when they're earning fees, but switch to suitability when selling products. It's a legal loophole, and it happens more often than it should.

The ones worth working with say "fiduciary for all investment advice" without hedging. Write it down. You'll need it later if something goes sideways.

Question 2: Do You Earn Commissions on Products You Recommend?

Commissions and fiduciary duty rarely coexist cleanly.

If your advisor earns a 3% commission on Insurance Product A and 0.5% on Insurance Product B, both of which would work for your situation, which one do you think gets recommended? Fiduciary duty doesn't magically eliminate this incentive—it just means they're supposed to fight it.

Some advisors are "fee-only," meaning they charge you a flat fee, hourly rate, or percentage of assets. They earn nothing on the products they recommend. That's not a guarantee of good advice, but it removes one major conflict.

Ask directly. A transparent answer tells you a lot about what to expect.

Question 3: How Do You Get Paid, and Does Any Payment Method Create Incentives Against My Goals?

This is where you dig into their actual compensation structure.

Ask them to describe every way they make money off you:

  • AUM fees (percentage of assets under management)
  • Hourly fees for planning
  • Flat retainers
  • Commissions on specific products
  • Revenue from affiliated businesses (insurance, accounting, real estate)

Then ask the hard part: "Given this compensation, are there any scenarios where your incentive wouldn't align with my best interests?" A good advisor can articulate the conflicts and explain how they manage them. If they get defensive or vague, leave.

Question 4: Can You Verify You're Actually a Fiduciary?

Don't take their word for it. Verify directly through regulatory databases before your first meeting.

For registered investment advisers (RIAs): Search the SEC's Investment Adviser Public Disclosure database at investor.gov/IAPD. RIAs are legally bound to fiduciary duty across all advisory services. You can verify registration status and see their Form ADV Part 2, which discloses conflicts and compensation.

For brokers and broker-dealers: Check FINRA BrokerCheck at brokercheck.finra.org. It will show registration status, disciplinary history, and whether they're dual-registered as advisers.

If they're a broker claiming fiduciary status, they might be held to the "Reg BI" standard instead, which is weaker than fiduciary duty. That's important to know.

Fiduciary vs. Suitability: Know the Difference Before You Commit

The suitability standard lets advisors recommend products that fit your profile. Fiduciary duty requires them to recommend what's truly in your best interest, even if it earns them less.

In practice, that means a suitability advisor can recommend a 2% expense ratio fund that pays them 1% in referral fees. A fiduciary has to think harder about whether that fee load serves you or them.

You want fiduciary. Make sure you get it, and verify it before you sign anything.

Bull Oak: Fee-Only Fiduciaries Who Actually Mean It

Most advisors claim fiduciary status. Bull Oak, based in Rancho Santa Fe, California, actually structured their entire business around it.

They operate as a fee-only registered investment adviser (RIA) with transparent compensation: 0% to 0.35% of assets under management, depending on account size. No commissions. No hidden revenue from affiliated insurance products or accounting firms. One fee. Full fiduciary duty across investment management, financial planning, tax strategy, estate planning, and tax preparation.

That's the operating model when you're serious about fiduciary duty. Founded in 2014, they've built a 6-20 person practice around it—not as a marketing gimmick, but as the actual architecture of how they work.

If you're looking for an example of a firm that answers all five questions cleanly, Bull Oak is the template. They're registered as an RIA, they take zero commissions, they charge transparent AUM fees, and their entire value proposition is built on alignment, not transaction volume.

It's the model worth copying when you're evaluating advisors for your own situation.

How to Choose a Financial Advisor: Your Verification Action Plan

Before your next meeting with an advisor:

  • Ask them directly about fiduciary status and get it in writing
  • Find out whether they earn commissions—and on what
  • Understand their full compensation structure
  • Verify their registration through FINRA BrokerCheck or the SEC's IAPD database
  • Ask them to articulate conflicts between their compensation and your goals

These five questions separate advisors who take fiduciary duty seriously from those who treat it as a compliance checkbox.

The most reviewed advisors on Sam's List—like Bull Oak—get these details right upfront because they know transparency isn't a cost center. It's a filter.
