What Is a Fiduciary Financial Advisor? How to Tell, and How to Check Anyone You Pay

Before you let someone else manage what you've saved, it helps to know which rule they have to follow, and how they get paid.

What is a fiduciary financial advisor?

A fiduciary financial advisor is someone who must put your interests before their own for as long as they advise you. In the law, this is the job of an investment adviser (the government spells it with an "e"), a person who helps you invest your money.

That duty has two parts. A duty of "care" means their advice can't be generic; it has to fit you. A duty of "loyalty" means your interests come before theirs.

A conflict of interest is anything that could make an adviser earn more by steering you one way, for example toward a product you don't really need. An adviser has to explain any conflict clearly enough that you can agree to it knowing what it means. If they can't make it that clear, they have to get rid of it or reduce it.

A broker has a license to buy and sell investments for you, and follows a different rule, called Regulation Best Interest. A broker is required to act in your best interest when making a recommendation.

The difference is timing. The broker's rule looks at the moment of the recommendation. It doesn't make the broker keep watching your account afterward, unless they've agreed to. An adviser's duty lasts as long as they advise you.

Does it apply to you?

If anyone is picking investments for you, or soon will be, then it applies to you. That includes moving an old 401(k) into an IRA (an individual retirement account you open yourself), buying a mutual fund (a pool of many people's money invested together), or handing over your savings to be managed.

The words "financial advisor" on a business card don't tell you which rule a person follows. In fact, some people work as both brokers and advisers, and switch hats from one account to another.

How someone gets paid is a strong clue to whether they are working as a broker or an adviser:

• Commission. These are payments made to brokers, usually each time you buy or sell. The more you trade or buy, the more they can earn.
• A fee based on your account. Advisers usually charge a fee worked out on the value of what they manage for you.
• Hourly or flat fee. Some advisers charge by the hour or a flat fee.

Some advisers call themselves "fee-only." That means you are the only one who pays them, and they earn nothing from what you buy or sell, according to NAPFA, a group of fee-only advisers.

Whatever someone calls themselves, ask them to show you how they are paid in writing.

Firms registered with the SEC, the federal agency that oversees investment firms, put it in a short summary called Form CRS. Smaller advisers, who usually register with their state, describe their fees in a longer document called a Form ADV brochure.

Your numbers: what a sales charge costs

Say you have $40,000 from an old 401(k). Someone suggests a mutual fund with a front-end sales load. That is a fee taken out when you buy, and it often pays the person who sold you the fund.

FINRA, which oversees brokers, gives an example of a fund that charges 5.75% on purchases under $50,000.

What does that mean for you?

• $40,000 times 5.75% is $2,300. That comes off the top.
• $40,000 minus $2,300 is $37,700. That is what actually gets invested for you.

In the same FINRA example, the charge drops to 4.50% at $50,000. These discounts are called breakpoints. If you are close to one, ask about it.

There is also a ceiling. FINRA's rules cap the total sales charges on most of these funds at 8.5% of the price, with lower caps in some cases.

A sales charge is legal, and the person may still be acting in your best interest. An adviser paid by a yearly fee on your account has a cost too. It just comes out of your account each year instead of at the start.

Either way, before signing any paperwork, ask to see the costs in dollars. The SEC suggests one question:

"If I give you $10,000 to invest, how much will go to fees and costs, and how much will be invested for me?"

At the same 5.75% charge, the answer is $575 in charges and $9,425 invested.

What to do

Before you sign anything or move any money, look up the person and the firm. It's free.

Go to Check Out Your Investment Professional on Investor.gov and type in the name.

For an adviser, it takes you to their record (Form ADV and the firm's Form CRS). For a broker, it sends you to FINRA's BrokerCheck.

The record shows whether the person or firm is a registered adviser, a broker, or both. That tells you which rule they follow.

Check the person and the firm. Look at licenses, the past 10 years of jobs, and any complaints or discipline. You can also call the BrokerCheck Help Line at 800-289-9999.

Two safety notes:

• Walk away from guaranteed returns, "risk-free" offers, pressure to invest right now, or any request to pay by gift card or by wiring money to a personal account. If the person is not licensed, do not invest.
• If something feels wrong, call FINRA's Securities Helpline for Seniors at 844-574-3577 (weekdays, 9 a.m. to 5 p.m. Eastern), or the SEC at 800-732-0330.

Quick answers

Q: Are all financial advisors fiduciaries? No. Investment advisers have a fiduciary duty under federal law, but brokers follow Regulation Best Interest. If someone is both, always ask which role they play for your account.

Q: What does fiduciary duty mean? It means an adviser must give advice that fits you and put your interests before their own. If something could sway their advice, they must explain it clearly enough that you can agree to it. If they can't, they must get rid of it or reduce it. This is a duty of care and a duty of loyalty.

Q: How do I know if my financial advisor is a fiduciary? You will find this on Investor.gov. Those registered as investment advisers have a fiduciary duty to their clients. Those registered only as brokers follow Regulation Best Interest. Some are registered as both. If so, ask which role they play for your account, and ask them to put it in writing.

Q: How do I check if a financial advisor is legit? Go to Investor.gov or FINRA's BrokerCheck and type in the name of the person or firm. Neither will cost you a cent, and both tell you whether the person is licensed. They also show where the person has worked before and list any complaints or discipline. Investor.gov warns that people who are not licensed or registered commit much of the investment fraud in the United States.
