Financial Adviser Negligence and Malpractice Claims
Representing investors nationwide whose adviser or broker failed to do the job the rules required, and who lost money because of it.
An adviser does not have to lie to be responsible for a loss. Failing to learn a client’s situation before recommending an investment, ignoring stated objectives, leaving a portfolio unattended, or letting a junior broker run an account unsupervised can each be enough. The rules that govern brokers and advisers set a standard of care, and a claim that the standard was not met is decided on the records the firm itself kept. Industria Business Lawyers represents investors in those claims nationwide.
This page explains the standards of care that apply to brokers and to investment advisers, the forms of negligence that most often reach an investor’s lawyer, where a claim is brought, the deadlines, and what to gather before you call. Every rule and statute cited was read at its source on 17 September 2026.
Every matter is reviewed on its own facts. Market losses alone are not negligence, and you will hear that plainly if that is what the records show.

Adviser Negligence Claims We Handle
Negligence claims against brokers and advisers usually take one of these forms. Each is measured against a written rule.
Failure to Know the Customer
Under FINRA Rule 2111, a broker must have a reasonable basis to believe a recommendation is suitable, based on reasonable diligence to learn the customer’s investment profile: age, other investments, financial situation and needs, tax status, objectives, experience, time horizon, liquidity needs, and risk tolerance. A recommendation made without that diligence is the most common negligence claim.
Recommendations Not in the Customer's Best Interest
Under SEC Regulation Best Interest, 17 C.F.R. 240.15l-1, a broker making a recommendation to a retail customer must act in the customer’s best interest at the time of the recommendation, without placing the broker’s or the firm’s interest ahead of the customer’s. A recommendation driven by commissions or a product’s payout to the firm can breach that obligation.
Investment Adviser Breaches
Under section 206 of the Investment Advisers Act, 15 U.S.C. 80b-6, it is unlawful for an investment adviser to employ any device or scheme to defraud a client or to engage in any practice that operates as a fraud or deceit on a client. Advisers owe clients a duty that reaches negligent management as well as deliberate misconduct: unmonitored accounts, ignored instructions, and strategies never explained.
Failure to Supervise
Under FINRA Rule 3110, each member firm must establish and maintain a system to supervise the activities of each associated person that is reasonably designed to achieve compliance with the securities laws and FINRA rules, and final responsibility for supervision rests with the firm. A broker’s negligence becomes the firm’s when the supervisory system did not catch it.
Overconcentration and Unmanaged Risk
A portfolio left in one stock, one sector, or one illiquid product long after the customer’s circumstances called for something else. Concentration claims are proved from the account statements and the customer’s stated profile.
Errors, Delays, and Unexecuted Instructions
Orders entered wrong, instructions not carried out, transfers delayed, and paperwork mishandled in ways that cost the customer money. Small in each instance, and often large in aggregate.
Where a Negligence Claim Is Brought, and by When
Forum depends on who the adviser is. Timing depends on which clock runs first.
Against a broker or a brokerage firm: FINRA arbitration. Under FINRA Rule 12200 a firm must arbitrate a dispute with a customer when a written agreement requires it or when the customer requests it, so long as the dispute arises from the firm’s business. Under FINRA Rule 12208 a party may be represented there by an attorney admitted in any U.S. state, which is why IBL represents investors in FINRA arbitration nationwide.
Against a registered investment adviser: arbitration or court. Advisers who are not FINRA members cannot be compelled into FINRA arbitration. The advisory agreement may name an arbitral body; if it does not, the claim goes to state or federal court.
The FINRA clock. Under FINRA Rule 12206, a claim is not eligible for arbitration once six years have passed from the occurrence or event giving rise to it.
The state clock. In Florida, an action founded on negligence must be brought within two years under section 95.11(4)(a), Florida Statutes, and an action not otherwise provided for within four years under section 95.11(3)(o). Other states set their own periods, and the shortest applicable period controls, so the dates are the first thing reviewed.
What the records show. Negligence claims are decided on the firm’s own paper: the new account form that records the customer’s profile, the suitability notes, the supervisory reviews, and the trade blotter. Under FINRA Rule 12506 the documents presumed discoverable in customer cases are set out in FINRA’s Document Production Lists, and each side must produce them within 60 days of the date the answer is due.
Next question: Is FINRA arbitration worth it? Then: How do I file a FINRA arbitration claim?

FAQ
01 • Securities My adviser did not lie to me. Do I still have a claim?
Possibly. Negligence is a failure to meet the standard the rules set, not a lie. A recommendation made without learning your situation, or an account left unsupervised, can be enough. The records decide it.
02 • Securities How do I separate market losses from my adviser's fault?
By comparing what the account did with what a suitable portfolio for your profile would have done over the same period. That analysis is part of every claim IBL brings.
03 • Securities Is a financial adviser a fiduciary?
A registered investment adviser is; the Advisers Act imposes the duty. A broker is held to Regulation Best Interest and FINRA’s suitability rule, which are strict but not identical. Which rule applies depends on who the person was when the recommendation was made.
05 • Securities What should I gather before I call?
Account statements for the full period, the account opening paperwork, every email and text with the adviser in date order, any risk questionnaire you completed, and a figure for the amount lost with the year it occurred.
