How to File a FINRA Complaint: A Step-by-Step Guide for Investors

Something feels off with your account. Maybe there’s a trade you never approved sitting on your statement. Maybe your advisor promised an investment was safe, and it wasn’t even close. Your gut says report it, but to whom, and what actually happens once you do?

This guide walks you through the entire FINRA complaint and arbitration process, from your first conversation with a compliance department to what regulators actually do with your case. Here’s what you’ll learn:

• What counts as reportable broker misconduct, and what FINRA actually investigates

• The exact steps to file a complaint through FINRA’s Investor Complaint Center

• Why a complaint alone won’t get your money back, and what will

• When it’s time to call a financial advisor complaint attorney

By the end, you’ll know exactly how filing a FINRA complaint fits into a bigger plan for recovering your losses, and why investors across the country contact Bakhtiari & Harrison when it’s time to pursue a FINRA arbitration claim.

FINRA Complaints Are Climbing, and the Numbers Back It Up

Investors aren’t imagining this. FINRA received 24,899 investor complaints directly in 2025, more than double the 11,908 logged the year before, according to FINRA’s own regulatory statistics. That same year, the regulator opened 625 new disciplinary actions and ordered $99.6 million in fines and disgorgement, plus another $17.1 million in restitution back to harmed investors.

The consequences for bad actors are real, too. In 2025 alone, FINRA handed down bar sanctions against 187 individuals and suspended another 235 from the securities industry, in addition to suspending four member firms and expelling one outright.

None of that happens without investors submitting complaints first. Every written complaint, every documented account of unauthorized trading, every instance of misconduct reported to FINRA becomes part of the information regulators may use when deciding whether to open an investigation or take disciplinary action. Filing one isn’t just paperwork. It’s how the securities industry polices itself.

What a FINRA Complaint Actually Does (and What It Doesn’t)

The Financial Industry Regulatory Authority, better known as FINRA, is the self-regulatory body that oversees brokerage firms and their registered representatives. When you file a complaint, you’re not suing anyone. You’re flagging potential rule violations to a regulator that can investigate, discipline, and, in serious cases, bar a broker from the securities industry for good.

Here’s the part that trips people up: a FINRA complaint is an investigative process, not a path to a check in the mail. It can lead to fines, suspensions, or a broker getting barred from the securities industry entirely, but it does not directly recover your losses. For that, you need a separate FINRA arbitration claim, where a neutral panel can actually award you money.

Action	Purpose	Typical Outcome
FINRA Complaint	Reports misconduct for regulatory review	Disciplinary action against the broker or firm (fines, suspension, bar)
FINRA Arbitration	Seeks financial recovery for your losses	A binding award, often after mediation or settlement

A lot of investors do both. They file a complaint to put the misconduct on the record, then pursue arbitration to recover what they actually lost.

Types of Broker Misconduct You Can Report to FINRA

You don’t need a law degree to know something’s wrong. If your broker or investment adviser did any of the following, it’s worth reporting:

• Unauthorized trading, meaning an unauthorized trade made in your account without your permission

• Churning or excessive trading to generate commissions rather than help you

• Unsuitable recommendations that didn’t match your risk tolerance or goals

• Selling away, where an advisor pitches products never approved by their firm

• Misrepresentation or omission of the risks, fees, or liquidity of an investment

• Elder financial abuse, a growing concern for retirees sold products they don’t understand

• Failure to supervise by a branch manager or compliance department

• Falsified or manipulated account statements

If any of this sounds familiar, especially stockbroker negligence or outright broker fraud, don’t wait. Evidence and memories fade, and elder fraud cases in particular tend to worsen the longer they go unreported.

How to File a FINRA Complaint: Step-by-Step Guide

Here’s exactly how the process works, from your first phone call to hitting submit.

Step 1: Contact Your Brokerage Firm First

Before filing a formal complaint, reach out to your broker or your firm’s compliance department. Many firms have internal processes built to resolve client complaints quickly, and this step can sometimes fix the problem without escalation. Stay calm, stay factual, and if the firm offers a resolution, get it in writing.

If you don’t get a satisfying answer, or the response confirms something is genuinely wrong, ask to speak with a branch manager, someone in the compliance department, or the office of supervisory jurisdiction overseeing your account.

Step 2: Gather Documents That Support Your Claim

Detailed records are the backbone of any FINRA complaint. Start collecting:

• Account statements showing the transactions in question

• Trade confirmations with dates, prices, and security names

• Emails, texts, and letters from your broker or advisor

• Marketing materials or investment proposals you were given

• Notes from phone calls or meetings, including dates

The more documents that support your version of events, the more seriously FINRA will take the complaint.

Step 3: Verify the Broker Through FINRA BrokerCheck

Before you submit anything, confirm you have the right person and firm. FINRA’s free BrokerCheck tool shows a broker’s registration status, employment history, and any prior customer complaints or disciplinary history. Our own guide to using BrokerCheck walks through exactly what to look for. Misidentifying a broker, especially in a firm with thousands of registered representatives, can delay your case for no reason.

Step 4: Submit Your Complaint Through FINRA’s Investor Complaint Center

You can file a complaint with FINRA online through the FINRA Investor Complaint Center. The online portal walks you through questions about you, the broker, the firm, and what happened. FINRA encourages investors to submit complaints through the online Investor Complaint Center; mail and fax options are available but less commonly used.

Step 5: Describe the Misconduct Clearly and Attach Evidence

FINRA investigators read hundreds of complaints a week, so specificity matters. Skip the emotional language. Instead of “my advisor lied to me,” try something like: “My advisor recommended a non-traded REIT described as low-risk and liquid. He didn’t disclose the 7 to 10 year lock-up period or the high commissions involved.” Attach copies, never originals, of everything that backs up your account.

Step 6: Save Your Confirmation and Cooperate With Follow-Up

Once submitted, you’ll get a confirmation and case number. Keep it. FINRA may reach back out for clarification or additional documents during its review, and staying responsive helps keep your case moving.

What Happens After You File a Complaint With FINRA

Once your complaint lands with FINRA, here’s roughly what unfolds:

• Initial review: FINRA checks whether the issue falls under its jurisdiction.

• Investigation: If warranted, FINRA may contact the firm, request records, and interview the parties involved.

• Outcome: If violations are confirmed, FINRA can take disciplinary actions ranging from fines to a full bar from the securities industry.

Even complaints that don’t lead to a slam-dunk enforcement action still matter. They become part of the broker’s regulatory record, visible on future BrokerCheck reports, and they can strengthen a related arbitration claim by documenting a pattern of misconduct.

Filing a FINRA Complaint vs. Pursuing FINRA Arbitration

This is the distinction that catches the most investors off guard. FINRA complaints and FINRA arbitration and mediation are two different tracks, and most customer agreements require arbitration for any dispute involving money.

Arbitration is where FINRA arbitration claims for compensation actually get resolved. You’ll file a statement of claim, and the case proceeds before a neutral panel, sometimes through settlement, sometimes through mediation, and occasionally all the way to a binding award. FINRA’s own data on arbitration outcomes for customers shows roughly 69% of customer cases settle and about 18% proceed all the way to a final award.

One important timing note: FINRA’s eligibility Rule 12206 generally bars arbitration claims once six years have passed from the event giving rise to the dispute. There’s no similar hard deadline for filing a complaint, but waiting rarely helps your case, especially once documents get harder to track down and memories start to blur.

Mediation and Arbitration: Your Two Paths to Compensation

Once you’ve decided to pursue money back, not just a regulatory record, you’ve got two main routes, and they’re not the same thing.

Mediation

Mediation is the informal option. A neutral mediator sits down with you and the brokerage firm and helps both sides work toward an agreement, face to face rather than in front of an arbitration panel. It’s voluntary, it’s confidential (nothing discussed becomes public), and it tends to move faster and cost less than a full arbitration hearing. A lot of disputes over excessive trading or unsuitable investments get resolved this way without ever escalating further. If mediation doesn’t produce an agreement, nothing is lost. You can still move forward with an arbitration claim.

Arbitration

Arbitration and mediation are both offered through FINRA’s Dispute Resolution Services, but arbitration is binding. A statement of claim gets filed, an arbitration panel is assigned, and the process unfolds much like a court hearing, complete with evidence, witnesses, and sometimes expert testimony. The panel’s decision, called an award, is final. Because arbitration clauses show up in nearly every brokerage customer agreement, this is usually the only forum available to investors seeking money for unauthorized trades, churning, or other broker misconduct.

How to File a Claim Against Your Financial Advisor for Compensation

If you actually want your money back, a complaint alone won’t cut it. You’ll need to file a FINRA arbitration claim, and this is where legal representation tends to matter most. A claim typically includes:

• A statement of claim laying out what happened and the damages you’re seeking

• Supporting documents that substantiate the alleged misconduct

• A calculation of your losses, including lost principal and, in some cases, lost opportunity

Whichever route your case takes, whether mediation, settlement, or a full hearing, the goal is the same: recovering the compensation you deserve and holding the broker or brokerage firm accountable.

Common Mistakes That Weaken a FINRA Complaint or Arbitration Claim

• Waiting too long. Delays hurt both your complaint and your arbitration eligibility.

• Leaving out details. Vague complaints get vague responses or get shelved.

• Skipping documentation. FINRA and arbitration panels work off evidence, not assumptions.

• Confusing a complaint with compensation. One triggers an investigation. The other seeks money.

• Misidentifying the broker or firm. Get the CRD number right before you file.

• Going it alone on a complex case. Selling away, elder abuse, and failure-to-supervise claims are hard to untangle without help.

Do You Need a Financial Advisor Complaint Attorney?

You can file a FINRA complaint yourself. Plenty of investors do. But if you’re also pursuing arbitration, which is the only path to actual compensation, having an experienced attorney can make a significant difference. An experienced FINRA arbitration attorney can:

• Pinpoint exactly which FINRA rules were violated

• Draft a complaint that’s precise enough to be taken seriously

• Coordinate the complaint with an arbitration claim so you don’t lose your shot at recovery

• Handle communication with FINRA investigators and the brokerage firm’s counsel

• Calculate damages and build the strongest possible case for your arbitration hearing

This matters just as much whether you’re dealing with a registered broker or an investment adviser operating under a different regulatory framework. Either way, protecting your interests as an investor starts with someone who’s done this before.

Filing a FINRA Complaint in California

California carries one of the largest concentrations of investors anywhere in the country, and that shows up in the complaint data. Retirees across the state are frequently steered into high-risk private placements, non-traded REITs, and structured products that never matched their stated risk tolerance in the first place. Advisors sometimes leave out the illiquidity, the 7 to 10 year lock-up periods, or the commissions baked into these products, then call them “safe.”

The filing process itself doesn’t change state to state. You’ll still go through FINRA’s Investor Complaint Center and, if you’re seeking compensation, still pursue a separate arbitration claim. What does change is how quickly and thoroughly a California investor should act, given how often selling away and elder financial abuse show up in complaints from the state. If your advisor discouraged you from looping in family members, pressured a quick decision, or sold a product they weren’t authorized to offer, treat that as a red flag worth documenting immediately.
