How to Find a Fiduciary Financial Advisor, and Verify They Are One
Last updated August 2026
Short answer
Look where they concentrate: fee-only planner associations, hourly and subscription networks, independent registered investment advisers found through the SEC's adviser search, and referrals from your accountant or attorney. Then verify rather than accept the claim, in three steps: confirm the firm is a registered investment adviser, read Form ADV Part 2A and its conflicts section, and ask whether the individual is also registered as a broker. Ask for the commitment in writing, at all times. Fiduciary and fee-only are two separate filters and are strongest applied together. Walnut is informational and is not an investment adviser.
Deciding you want a fiduciary is the easy part. The word appears in a great deal of marketing by people whose obligations are more complicated than the marketing suggests, and the distance between claiming it and being it is a document rather than a conversation.
Where they concentrate
1. Fee-only planner associations
Membership requires meeting a compensation standard, so the population is pre-filtered on the thing that creates most conflicts. Not identical to a fiduciary filter, and heavily overlapping with it in practice.
2. Hourly and subscription planner networks
Organised around charging for work rather than for assets, which means they take clients that percentage-based firms decline. Almost all are registered investment advisers and therefore fiduciaries in the advisory relationship.
3. Independent registered investment advisers directly
The SEC's adviser search lets you find registered firms and read their Form ADV before contacting anyone, which inverts the usual order. Slower than a directory, and it is the only channel where you verify first and meet second.
4. Referrals from your accountant or attorney
They have seen the advisor's work on real client situations rather than met them socially. Ask directly whether a reciprocal referral arrangement exists, which is a normal question with a normal answer.
The third channel is slower and better, because it inverts the normal order. Instead of meeting someone and then checking them, you read the firm's registration and brochure first and contact only the ones that survive, which means no time is spent being persuaded by a firm you were going to rule out.
Three steps that turn a claim into a document
1. Confirm the firm is a registered investment adviser
Search the SEC's adviser database, or your state regulator for smaller firms. A registered investment adviser owes a fiduciary duty in the advisory relationship, and this is the structural fact underneath any claim someone makes verbally.
2. Read Form ADV Part 2A, particularly the conflicts section
The brochure must describe how the firm is compensated and what conflicts arise. This is where you discover commissions, affiliated products or revenue-sharing arrangements that a conversation would have described more gently.
3. Ask whether they are also registered as a broker
Dual registration is common and not disqualifying, and it means the fiduciary duty attaches to the advisory capacity rather than to everything they do with you. Someone operating in both should be able to draw the line clearly.
Step two is where the surprises are. A brochure has to describe compensation and conflicts in plain language, and the picture it gives is frequently less flattering than the same information delivered warmly across a table. See the full record check.

Walnut is the AI that knows your portfolio: ask anything in plain English, research any fund, and get an honest second opinion. On the broker you already use, read-only, and you approve every trade. Walnut is not a registered investment adviser.
What a written commitment should say
| Clause | Why it is there |
|---|---|
| I will act as a fiduciary at all times | The phrase at all times is what closes the dual-registration gap |
| I will disclose all sources of compensation | Including anything received by the firm or an affiliate, not only by the individual |
| I will not receive commissions on what I recommend | This is the fee-only filter, and it is separate from the fiduciary one |
| I will disclose conflicts and how they are managed | A fiduciary may have conflicts. Undisclosed ones are the problem |
Requesting this is reasonable and the reaction is informative either way. For a fee-only registered investment adviser it restates obligations their own brochure already describes, so it costs them nothing. Reluctance usually indicates dual registration and a preference for leaving the boundary undefined.
Two filters, not one
Fiduciary is about the standard of care
It obliges an advisor to act in your best interest and to disclose and manage conflicts. It does not prohibit conflicts, so a fiduciary can lawfully receive commissions provided they are disclosed and managed appropriately.
Fee-only is about where the money comes from
It removes the commission conflict at the source rather than managing it. An advisor can be fee-only and not a fiduciary in some capacity, and can be a fiduciary while not being fee-only, which is why applying both filters is stronger than either.
Applying both is what people usually mean when they say they want a fiduciary. One sets the standard the advice must meet, the other removes the incentive that most often pulls against it, and neither substitutes for the other.

FAQ
How do I find a fiduciary financial advisor?
Look where they concentrate: fee-only planner associations, hourly and subscription planner networks, independent registered investment advisers found through the SEC's adviser search, and referrals from your accountant or attorney. Then verify rather than accepting the claim, because the word is used loosely.
How do I verify that an advisor is a fiduciary?
Three steps. Confirm the firm is a registered investment adviser through the SEC or your state regulator, read Form ADV Part 2A and particularly its conflicts section, and ask whether the individual is also registered as a broker. The duty attaches to the advisory capacity, so dual registration changes what a yes means.
Should I ask an advisor to sign a fiduciary oath?
It is a reasonable request and the reaction tells you something either way. The clause that matters is acting as a fiduciary at all times, since that closes the gap created by dual registration. A written commitment is also easier to point back to later than a recollection of a conversation.
Is fiduciary the same as fee-only?
No, and applying both is stronger than either. Fiduciary describes the standard of care, which permits conflicts provided they are disclosed and managed. Fee-only describes where the money comes from and removes the commission conflict at the source. An advisor can be one without being the other.
Are all registered investment advisers fiduciaries?
They owe a fiduciary duty in the advisory relationship, which is the practical answer. What complicates it is that many individuals are also registered as brokers, and the obligation attaches to the capacity they are acting in rather than to the person permanently.
Do fiduciary advisors cost more?
Not inherently, and frequently less once total cost is counted. Fee-only fiduciary firms charge visibly, which makes the cost feel larger than commission-based arrangements where the payment is embedded in products. The visible number is usually the smaller one.
Can a bank advisor be a fiduciary?
Sometimes, in the advisory portion of their work, and banks commonly operate both advisory and brokerage businesses. The question to ask is which capacity applies to your relationship and whether the answer is at all times, rather than whether the institution has a fiduciary arm somewhere.
What if they refuse to confirm it in writing?
That is an answer. A registered investment adviser's own brochure already describes the firm's obligations, so confirming in writing costs a fiduciary nothing. Reluctance usually signals dual registration and a wish not to define the boundary precisely.
