When you hire a financial advisor, you might assume they're legally required to act in your best interest. Most of them aren't. Understanding who is — and who isn't — a fiduciary is one of the most important things you can learn before trusting anyone with your money.

The Fiduciary Standard
A fiduciary is a person or entity legally obligated to act in your best interest — putting your financial wellbeing ahead of their own compensation or other interests. If a fiduciary recommends an investment that pays them a higher commission when a better, cheaper option exists, they have violated their fiduciary duty.
This sounds like the baseline standard. It isn't.
The Suitability Standard — What Most Advisors Follow
Most brokers and financial advisors operate under a suitability standard: they only need to recommend products that are "suitable" for you given your age, income, and goals. They don't have to recommend the best option — just one that isn't wildly inappropriate.
Under the suitability standard, a broker can recommend a mutual fund with a 1.5% expense ratio and a sales load when an identical index fund costs 0.03% — because the more expensive fund is "suitable." The fact that the broker earns a higher commission from the expensive fund is legally irrelevant.
This is not hypothetical. It has cost American investors billions of dollars.
The Reg BI Rule: A Partial Fix
In 2020, the SEC introduced Regulation Best Interest (Reg BI), which requires brokers to act in the "best interest" of customers — but falls short of a true fiduciary standard. Critics argue Reg BI has too many exceptions and too little enforcement to meaningfully close the gap.
The bottom line: Reg BI moved the needle, but it did not make all advisors fiduciaries.
Who Is a Fiduciary?
Registered Investment Advisors (RIAs) are registered with the SEC or state securities regulators and are legally held to the fiduciary standard. They must act in clients' best interests at all times.
CFPs (Certified Financial Planners) who provide financial planning are required to act as fiduciaries by the CFP Board's code of ethics (since 2020).
ERISA fiduciaries — advisors managing employer retirement plans under ERISA are subject to fiduciary standards for those accounts.
401(k) plan administrators have fiduciary duties to plan participants.
Compensation Models: Why It Matters
How an advisor gets paid determines their incentives:
Fee-only: Charges only fees paid directly by you — hourly, flat fee, or percentage of assets under management. No commissions. No product sales. Strongest alignment with your interests.
Fee-based: Charges fees AND earns commissions from product sales. Sounds similar to fee-only but has commission-based conflicts.
Commission-only: Earns money exclusively from selling products. Has inherent incentive to recommend products that pay higher commissions.
A fee-only fiduciary is the gold standard. You can find them at NAPFA.org (National Association of Personal Financial Advisors) — all members are required to be fee-only fiduciaries.
How to Ask the Right Questions
Before hiring any financial advisor, ask directly:
- "Are you a fiduciary at all times?" (Not just sometimes — some advisors switch standards depending on what they're doing)
- "How are you compensated?" (Request a complete list of all ways they earn money)
- "Do you receive any third-party compensation for recommending specific products?"
- "What is your Form ADV?" (Registered Investment Advisors must file this disclosure document — it lists conflicts of interest)
An advisor who hesitates or deflects on these questions is telling you something.
Do You Even Need a Financial Advisor?
For many people — particularly those with straightforward financial situations — the answer is no, or not yet. A simple three-fund portfolio in low-cost index funds, properly allocated for your age, requires no ongoing advisor.
Where advisors provide clear value:
- Complex tax situations
- Business ownership, equity compensation, or stock options
- Estate planning coordination
- Major life transitions (divorce, inheritance, retirement)
- Behavioral coaching during market volatility (underrated value)
If you do hire an advisor, a fee-only fiduciary who charges a flat or hourly fee (rather than percentage of assets) often provides the clearest value for the cost.
The word "fiduciary" isn't magic — but it does define a legal standard of accountability that matters. Before handing anyone discretion over your money, know exactly which standard they're operating under.
