Questions to Ask a Financial Advisor — 20 Vetting Questions That Actually Matter

Not financial advice. This page covers how to evaluate and compare advisors when you're in the interview stage.

Most "questions to ask a financial advisor" lists end at the surface. They tell you to ask about credentials, investment philosophy, and communication style — important, but incomplete. If you're looking for a flat-fee or fee-only advisor specifically, you need a different set of questions: ones that expose compensation conflicts, clarify what's actually included in the fee, and distinguish advisors who operate as true fiduciaries from those who use "fee-only" as branding.

This list is organized by category. Don't fire all 20 at once — use the compensation questions first as a filter, then go deeper with the candidates who pass.

Category 1: Compensation screening (ask these first)

These questions separate genuine fee-only advisors from fee-based ones who use similar language.

1. "How are you compensated — and are there any revenue sources beyond client fees?"

This is the only question that truly matters on compensation. Most advisors will say "I'm fee-only" and stop there. Push further: are there referral fees from custodians, revenue-sharing from investment products, 12b-1 fees, insurance commissions on any product they might recommend? A true fee-only advisor has zero external revenue sources. Their entire income comes from client fees — period.

Good answer: "My only compensation is the retainer fee you pay me. I use [Custodian X] because I like their platform, not because of any revenue arrangement." They can document this in writing.

Bad answer: Any mention of commissions, "third-party compensation," or "some clients prefer the commission model" — this is a fee-based advisor, not fee-only, regardless of what their website says.

2. "May I see your Form ADV Part 2?"

Form ADV Part 2 is the advisor's required SEC disclosure document.¹ It lists all revenue sources, conflicts of interest, and disciplinary history. Any registered investment adviser must provide this on request — if an advisor hesitates or claims not to have one, walk away.

Look at Item 5 (compensation arrangements) and Item 10 (other financial industry activities and affiliations). Any revenue sources beyond client fees appear here. If their marketing says "fee-only" but Item 5 discloses commissions or revenue-sharing, trust the ADV, not the marketing.

Good answer: They hand it to you immediately, or send a link to it on the SEC IAPD database within the day.

3. "Are you a fiduciary at all times, or only during certain transactions?"

Registered investment advisers (RIAs) are fiduciaries under the Investment Advisers Act of 1940 — this applies continuously.² Broker-dealers operate under Regulation Best Interest (Reg BI), which applies only at the point of a product recommendation, not to ongoing financial planning conversations.

Some advisors are dually registered: they operate as RIAs for planning and as broker-dealers for certain product transactions. In those transactions, the fiduciary duty drops. If you want a true fiduciary relationship, you want an RIA-only firm.

Good answer: "I'm an RIA only — no broker-dealer affiliation. My fiduciary duty applies to every recommendation I make."

Watch for: "I operate under the best-interest standard at all times." This can mean Reg BI (best-interest, not fiduciary) — the standards are different.

4. "What's your exact fee, and what does it include — what does it not include?"

Flat-fee advisors quote a specific number ($4,500/year, $8,000/year), not a percentage. But what's included varies enormously across firms. Some retainers include investment management; others cover planning only and you manage your own portfolio. Some include tax-return prep; others coordinate with your CPA but don't prepare returns. Some include estate document review; others don't.

Get the full list in writing: what's in scope, what triggers an additional fee, and how the fee changes if your situation changes.

Also ask: "If my situation becomes significantly more complex (divorce, business sale, inheritance), does the fee change, and how?"

5. "Do you receive any revenue from custodians, investment products, or referral arrangements?"

Some fee-only advisors use custodians who pay for "shelf space" via revenue-sharing, or receive conference sponsorships from investment product providers. These aren't commissions in the traditional sense, but they can bias recommendations. A transparent advisor discloses these proactively; a less transparent one doesn't mention them until asked.

Category 2: Services and fit

6. "What types of clients do you work with most, and do you specialize in any situations?"

Advisors who specialize serve their niche better than generalists. If you're a tech employee with RSUs and ISOs, an advisor who primarily works with tech executives will give you more relevant advice than a generalist who sees one equity-comp situation per year. Ask for specifics: how many clients have similar situations to yours, and what's the most common scenario they help those clients navigate?

7. "Walk me through what the first year of working together looks like."

This reveals the advisor's actual process. A good advisor describes a specific onboarding: data gathering, a comprehensive plan with defined deliverables, a meeting cadence, and what happens if you have a question between scheduled check-ins. Vague answers ("we'll get to know each other and see what you need") are a yellow flag.

8. "What's your investment philosophy, and do you manage investments or coordinate with a third party?"

Flat-fee advisors vary on the investment management question. Some manage portfolios directly (often at a custodian like Schwab, Fidelity, or TD); others provide financial planning only and either let you manage your own portfolio or coordinate with a separate investment manager. Neither approach is inherently better — but you need to know which model they use and whether it fits your situation.

9. "How many clients do you work with?"

A solo RIA with 80 clients can give you genuine attention. A solo RIA with 250 clients probably can't. Industry research suggests CFPs handling comprehensive planning can serve 50-100 clients well; pushing beyond 150 often means reactive service.³ Ask how many clients they have, and what the typical client-to-advisor ratio is at their firm.

10. "Do you work with clients remotely, or do you require in-person meetings?"

Most fee-only advisors today work with clients nationally via video. If you're in a smaller market with fewer local fee-only options, this matters — you shouldn't limit your advisor search to a 25-mile radius when the best specialist for your situation might be in a different city.

Category 3: Qualifications and track record

11. "What credentials do you hold, and what do they require?"

The CFP® (Certified Financial Planner) is the most recognized comprehensive planning credential — 6,000+ hours of experience, a comprehensive exam, an ethics requirement, and 30 hours of CE every two years.⁴ A CPA/PFS (Personal Financial Specialist) is a CPA who also holds the PFS credential — stronger on tax than on investment planning. A CFA (Chartered Financial Analyst) is deep on portfolio management and investment analysis but not specifically trained in financial planning.

Many excellent advisors hold multiple credentials. None of these is strictly required — but an advisor with no credentials and no explanation is a yellow flag.

12. "Have you ever had a regulatory action, customer complaint, or arbitration?"

FINRA BrokerCheck and the SEC's IAPD database list disciplinary history. Any credentialed advisor should be willing to point you to their record proactively. If you find disclosures and the advisor hasn't mentioned them, ask directly what happened. Minor administrative issues (late filing, etc.) are different from complaints or awards against them.

13. "How long have you been a fee-only advisor, and what was your background before?"

Recent converts from AUM or broker-dealer firms may still have mental models shaped by those environments. An advisor who's been fee-only for 15 years has a different perspective than one who switched 18 months ago. Neither is disqualifying — but the answer gives context for how deeply the fee-only philosophy is embedded in how they practice.

Category 4: Communication and process

14. "How do clients reach you between scheduled meetings, and what's your typical response time?"

One of the most common complaints about AUM advisors: they're only available during scheduled quarterly reviews. Flat-fee advisors typically offer more access — but the specifics vary. Some have unlimited email access; some charge for phone calls beyond a certain number. Know the rules before you're in a situation where you need a quick answer.

15. "What decisions do you make on my behalf, and what requires my approval?"

If the advisor manages investments, understand the discretion arrangement. Discretionary authority means they can trade without your approval; non-discretionary requires your sign-off on each transaction. Neither is wrong, but know which you're agreeing to. For planning decisions, most fee-only advisors recommend but don't implement without client approval.

16. "How do you handle a situation where you disagree with what I want to do?"

This is a culture question. A good advisor can name specific examples — "if a client wanted to hold a concentrated position I thought was too risky, I'd model the scenarios, explain my concern, and ultimately respect the decision because it's their money." An advisor who gives a vague or pressured answer ("I'd talk you out of it") may not respect client autonomy as much as they should.

Category 5: Flat-fee-specific deal-breakers

These questions apply specifically when you're evaluating whether a flat-fee model is genuinely what they offer.

17. "If my investable assets grow significantly, does my fee increase?"

A true flat-fee advisor charges a fixed amount unrelated to portfolio size. Some advisors use "flat fee" language but tie their fee to a portfolio percentage or have escalator clauses as AUM grows. If the fee goes up automatically when your assets increase, it's functionally an AUM model with a different label.

Good answer: "No. The fee is based on the scope of services, not your portfolio value. If your situation changes and requires significantly more work, we'd renegotiate the scope — but asset appreciation alone doesn't change your fee."

18. "Can I engage you for a one-time project or a single hourly session?"

Not all flat-fee advisors offer project-based or hourly work — some require an annual retainer relationship. If you want a second opinion on a specific decision (a portfolio review, a Roth conversion analysis, a pre-retirement projection), you need an advisor who offers hourly or project-based engagement. Confirm whether that's available before assuming it is.

19. "What happens if I decide to manage my own investments after working with you — does the relationship end?"

Fee-only advisors who don't manage investments are fully compatible with a DIY investing approach. But advisors whose flat-fee retainer includes investment management may see the relationship differently. Clarify whether the planning value is separable from the investment management — and whether you can have one without the other.

20. "Can you give me two or three references from current clients with situations similar to mine?"

Many advisors will say they can't share client names for privacy reasons — that's legitimate. But they can ask willing clients for permission to be references, or they can provide written testimonials. An advisor with zero ability to show you evidence that actual clients are happy is a yellow flag.

Red flags that end the conversation

• They don't know what Form ADV is, or claim not to be required to file one.
• They describe themselves as "fee-only" but mention product compensation in any part of the conversation.
• They can't give you a specific dollar fee before the first meeting — if the fee structure is so complex it can't be explained upfront, that's the structure working against you.
• They pressure you to decide quickly — "another client is interested in this relationship" is a sales tactic, not how genuine advisors operate.
• They guarantee returns or promise to "beat the market." Competent fiduciaries don't make performance guarantees.
• They discourage you from looking at their Form ADV or BrokerCheck record.

How to run the interview

Most fee-only advisors offer a free 30-minute discovery call. Use the first 10 minutes to establish rapport and let them explain their firm. Then move to the compensation questions — those answers tell you immediately whether it's worth continuing. If the compensation structure is genuinely fee-only, go deeper on services, fit, and process.

Interview at least two or three advisors. The comparison itself is valuable: you'll learn what's standard, what's above average, and which communication styles feel right for how you want to work. Most people who've hired a fee-only advisor say they wish they'd done the comparison earlier.
