How to Find a Fiduciary Financial Advisor for Your Family

By Kevin Luu, Co-Founder and Chief Learning Officer. Reviewed on 2026-09-30.

To find a fiduciary financial advisor, start with a fee-only registered investment adviser, confirm on the SEC’s public database and in the firm’s Form ADV that the adviser owes you a fiduciary duty on every account, and get the total annual cost in dollars before you sign. Then test them on your own situation: RSUs, California or Washington taxes, the kids’ accounts and your estate documents. A good fiduciary will answer specifically. A salesperson will change the subject to products.

This guide is written for W-2 households earning roughly $750,000 to $3 million, often two professionals at a hospital, a biotech, Apple or Amazon, with young children and very little free time. You do not need the “best” advisor in a ranking. You need one who is legally on your side and can handle the parts of your finances that are actually hard.

What “fiduciary” means, and what it does not

A registered investment adviser owes a fiduciary duty under the Investment Advisers Act of 1940. The SEC describes it as a duty of care and a duty of loyalty that applies to the entire relationship, not just a single trade (SEC interpretation, Release IA-5248). In practice, the adviser must put your interests first and either remove conflicts of interest or disclose them clearly enough that you can give informed consent.

A broker-dealer representative works under a different rule, Regulation Best Interest. It applies at the time a recommendation is made and does not, by itself, create an ongoing duty to monitor your account afterward (SEC Release 34-86031). Many professionals are both: they act as fiduciaries on an advisory account and as brokers when they sell you an insurance product or a commissioned fund. That is legal, and it is the main reason “Are you a fiduciary?” is the wrong question. The right one is “Are you a fiduciary on everything you recommend to us, all the time, in writing?”

Titles do not settle it. “Financial advisor”, “wealth manager” and “private banker” are not legal standards. For more on how common true fiduciaries are, see what percentage of financial advisors are fiduciaries.

Step 1: Write down the job before you search

High-income W-2 families usually need help with a short list of specific problems. Write yours down first, because it decides who qualifies:

• Equity compensation. RSU vests, ESPP purchases, ISOs or NSOs, and a concentrated position in your employer’s stock.
• Taxes in your state. California taxes capital gains as ordinary income, with a top rate of 13.3% for 2025 (FTB 2025 tax rate schedules; FTB on capital gains). Washington has no wage income tax today, but from 2025 it taxes long-term capital gains above an annual standard deduction ($278,000 for 2025) at 7%, and 9.9% on taxable gains above $1 million (WA DOR), and a 9.9% income tax on AGI over $1 million starts in 2028 (WA DOR income tax).
• Employer plans. 401(k) and mega backdoor Roth, deferred compensation, dependent care FSA.
• The kids. 529 plans, custodial accounts, guardianship and trusts in your wills.
• Time. Whether you want a plan you execute yourself or someone who coordinates your CPA and estate attorney for you.

An adviser who only manages investment portfolios may be a fiduciary and still be the wrong fit if most of your problem is RSU taxes and an estate plan written before your second child was born.

Step 2: Build a shortlist from sources that are not paid placements

Start with sources where advisers cannot buy their ranking:

• Referrals from your CPA or estate attorney. They see adviser work up close at tax time and when documents are signed.
• The SEC’s Investment Adviser Public Disclosure site (adviserinfo.sec.gov), which covers SEC-registered and state-registered advisers.
• The CFP Board’s verification tool (cfp.net). The CFP Board’s standards require CFP professionals to act as fiduciaries when providing financial advice (CFP Board Code and Standards).
• Fee-only membership directories, where advisers attest that they take no commissions.

Be cautious with “top advisor” lists and matching services. Many are funded by the advisers they list, which is a form of paid placement. That does not make the advisers bad, but the list is marketing, not vetting. Our checklist on what a vetted financial advisor is covers the full background check.

Step 3: Verify fiduciary status on paper, not in conversation

Every registered adviser files public documents that answer most of your questions before the first meeting:

1. Form ADV Part 2A (the brochure). It lists fees, how the firm is paid, conflicts of interest and disciplinary history. Look for any mention of commissions, 12b-1 fees, insurance sales or revenue sharing.
2. Form CRS. A short relationship summary that says whether the firm is an adviser, a broker or both (Investor.gov). If it says both, ask which hat applies to each account.
3. BrokerCheck (brokercheck.finra.org). If the person also holds a broker registration, this shows it, along with any complaints.
4. Your state regulator. Smaller advisers register with the state. In California that is the Department of Financial Protection and Innovation (DFPI); in Washington, the Department of Financial Institutions Securities Division (DFI).

Then ask for one sentence in the advisory agreement: that the firm acts as a fiduciary at all times, on all accounts and all recommendations. A true fee-only fiduciary can sign that easily.

Step 4: Interview questions that separate fiduciaries from salespeople

For the held-away question, see what held-away assets are.

Worked example: three proposals for a $1.2 million Bay Area household

Assumptions (illustrative): married couple filing jointly in California, $600,000 of base salary plus $600,000 of RSUs vesting in 2026, standard deduction only, no other income. Investable assets of $4 million: $1.5 million in employer stock, $1.5 million in a taxable brokerage account and $1 million in 401(k)s. Two children, ages 3 and 7.

The tax problem a good adviser should catch first. For 2026, employers typically withhold federal tax on RSU income at the optional 22% supplemental rate; only supplemental wages above $1 million in a year face mandatory 37% withholding (it does not apply here) (IRS Publication 15, 2026). With $1,167,800 of taxable income ($1.2 million minus the $32,200 standard deduction for 2026), about $200,900 of the RSU income falls in the 35% bracket and $399,100 above the $768,700 start of the 37% bracket (Rev. Proc. 2025-32). The federal tax on the RSUs is about $218,000, while 22% withholding collects $132,000. Assuming withholding on salary roughly covers the tax on salary, that can leave about $86,000 owed in April at the federal level alone. California comes on top: at this income the marginal California rate is 12.3% (the 11.3% bracket plus the 1% Behavioral Health Services Tax on taxable income over $1 million, using 2025 schedules; the 13.3% top rate starts above $1,485,906 for joint filers) (FTB 2025 schedules), plus 1.3% SDI on all wages for 2026 (EDD).

The three proposals (fees hypothetical):

Proposal C can be the most expensive, in a way you cannot see on a statement. Proposal A is a fiduciary, but its advice stops at the accounts it holds, so the 401(k)s and the RSU plan (the $86,000 withholding gap and the new shares that keep adding to the employer stock position) fall outside its scope. Proposal B costs $6,000 a year less than A and covers the problems that matter. Over ten years, that is $60,000 in fees before any growth, plus whatever value comes from a planned sale of employer stock. For more on pricing, see how much fee-only financial planners cost.

Common mistakes high-income families make

• Hiring the employer’s preferred broker by default. The stock plan administrator is convenient, not necessarily independent.
• Comparing percentages instead of dollars. 0.8% of $5 million is $40,000 a year. Ask for the number.
• Choosing on investment returns. At your income, taxes, concentration and estate documents usually move more money than fund selection.
• Treating “near me” as a requirement. Location matters less than whether the adviser knows California or Washington tax rules and your employer’s equity plan.

What to document for your kids

Once you choose an adviser, write a one-page note: who you hired, why, how they are paid, and what you asked them to watch. Your children will one day choose advisers of their own, likely with less context than you have now. As Kevin Luu puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.” The family governance service covers how to keep that record.

Frequently asked questions

Is a fee-based advisor the same as a fee-only fiduciary?

No. “Fee-only” means the adviser is paid only by you. “Fee-based” usually means an advisory fee plus commissions on some products. A fee-based adviser can be a fiduciary on the advisory account and a broker on the products, so read Form CRS and Form ADV Part 2A to see which role applies to each recommendation.

How do I find the best fiduciary advisor near me?

Search the SEC’s adviser database for firms in your area, then filter for fee-only firms that work with equity compensation and families with young children. Most planning happens by video and shared documents now, so an adviser in another city can work well if they know California or Washington tax rules. Check your state regulator for any local disciplinary history.

Are all CFP professionals fiduciaries?

The CFP Board requires CFP professionals to act as fiduciaries when they provide financial advice. That is a professional standard enforced by the CFP Board, separate from the legal duty an investment adviser owes under federal or state law. A CFP who is also a broker can still earn commissions, so check how they are paid as well as the credential.

Your next step

Pull the Form ADV Part 2A and Form CRS for every adviser on your shortlist, and send each one the same two-paragraph summary of your RSUs, accounts and family. Compare the answers in dollars and specifics. If you want a second opinion on the RSU and tax side, our tax management team offers a Tax & Wealth Assessment.
