Breach of Fiduciary Duty in Florida: A Complete Guide

By Steven M. Katzman

Some business relationships are built on arm’s-length bargaining, where each side is expected to look out for itself. Others are built on trust, and the law treats them very differently. When you hand someone control over your money, your company, or your family’s inheritance, whether a business partner, a corporate officer, a trustee, or a financial advisor, Florida law imposes fiduciary duties on that person: obligations of loyalty, honesty, and care that sit above ordinary contract promises. When those duties are broken, the harm is rarely a single bad decision. It is self-dealing, diverted opportunities, hidden profits, and books that no longer add up.

A word of caution before anything else: fiduciary breach cases are won and lost on records, and the person you suspect usually controls them. Before you confront anyone, quietly gather what you can, your agreements, account statements, distributions, emails, and tax returns, and understand your inspection rights, because Florida law gives shareholders, LLC members, partners, and trust beneficiaries powerful tools to demand the underlying books. Confronting a fiduciary before you understand the paper trail gives them time to explain, paper over, or delete. And remember the deadlines: most fiduciary duty claims in Florida must be brought within four years, and trust beneficiaries can face far shorter windows once a trustee’s disclosures start the clock.

This guide explains how breach of fiduciary duty claims actually work in Florida: who owes these duties, what you must prove, the most common ways fiduciaries go wrong, the defenses you should expect, what you can recover, and the practical steps that protect your position from day one.

What is a fiduciary duty under Florida law?

A fiduciary duty is the highest standard of care the civil law imposes. It arises when one person places trust and confidence in another to act for their benefit, and the other accepts that role. Florida law recognizes two broad sources:

• Formal fiduciary relationships, created automatically by law or by a defined role: corporate directors and officers, LLC managers, general partners, trustees, personal representatives of estates, guardians, and agents acting under a power of attorney.
• Implied fiduciary relationships, which Florida courts find when the facts show one party reposed trust and the other accepted the duty, even without a formal title. Long-standing advisory relationships and joint venturers can qualify. The label on the relationship matters less than who actually held the trust and the control.

Two core obligations run through all of them. The duty of loyalty requires the fiduciary to put the beneficiary’s interests ahead of their own: no self-dealing, no secret profits, no competing, no diverting opportunities. The duty of care requires the fiduciary to act with reasonable diligence and informed judgment, not recklessly or in willful disregard of the interests they serve.

Who owes fiduciary duties in Florida?

The list is longer than most people expect, and each role carries its own statute:

• Corporate directors and officers. Under Fla. Stat. § 607.0830, directors must act in good faith and in a manner they reasonably believe to be in the corporation’s best interests. Their personal liability is governed by Fla. Stat. § 607.0831. Disputes among owners of closely held companies are the heart of our shareholder and corporate litigation practice.
• LLC managers and managing members. Under Fla. Stat. § 605.04091, managers of a manager-managed LLC and members of a member-managed LLC owe the company and each other duties of loyalty and care.
• Partners. Under Fla. Stat. § 620.8404, each partner owes the partnership and fellow partners duties of loyalty and care, including a duty to account for any benefit derived from partnership business. These fights are the focus of our partnership litigation practice.
• Trustees. Florida’s Trust Code, Chapter 736, requires a trustee to administer the trust in good faith, solely in the beneficiaries’ interests, with the duty of loyalty codified at Fla. Stat. § 736.0802.
• Personal representatives of estates. Under Fla. Stat. § 733.602, a personal representative is a fiduciary held to the same standard as a trustee. Estate and trust fights run through our probate litigation practice.
• Agents under a power of attorney. Fla. Stat. § 709.2114 imposes strict loyalty and recordkeeping duties on attorneys-in-fact, a frequent battleground in exploitation-of-the-elderly cases.
• Stockbrokers and investment advisers. Financial professionals who exercise discretion or give advice can owe fiduciary duties under Florida common law and federal securities regulation, which we pursue through our securities litigation practice.

The elements of a breach of fiduciary duty claim

Florida courts require a plaintiff to prove three elements:

1. A fiduciary duty existed. By statute, by role, or by an implied relationship of trust and confidence.
2. The fiduciary breached it. Self-dealing, disloyalty, concealment, or a failure of care.
3. The breach proximately caused damages. The loss must flow from the breach itself.

Hypothetically: the managing member of a Boca Raton real estate LLC quietly forms a second company, steers the LLC’s best acquisition target to it, and finances the purchase using a lender relationship built on the LLC’s track record. The other members lose the deal and its profits. Those facts line up with each element: a statutory duty under § 605.04091, a classic loyalty breach through a usurped opportunity, and measurable damages in the profits the venture would have earned.

Common ways fiduciaries breach their duties

After decades of litigating these cases on both sides, we see the same patterns repeat:

• Self-dealing. The fiduciary sits on both sides of a transaction: selling company property to himself, leasing from an entity he owns, or setting his own above-market compensation.
• Usurping opportunities. A director, manager, or partner takes for himself a deal that belonged to the business.
• Secret profits and kickbacks. Undisclosed commissions, rebates, or side payments from vendors and counterparties.
• Commingling and diversion of funds. Company or trust money flowing into personal accounts, or “loans” to insiders that are never documented or repaid.
• Competing against the beneficiary. Building a rival business, soliciting the company’s customers, or exploiting its confidential information while still owing loyalty.
• Concealment and false reporting. Books kept from co-owners, altered financials, trust accountings that hide transfers, or distributions reported but never made.
• Favoritism by trustees and personal representatives. Administering a trust or estate to benefit one beneficiary, often the fiduciary’s own family line, at the expense of the others.

Hypothetically: a trustee of a Florida family trust, who is also one of three sibling beneficiaries, sells the trust’s waterfront lot to her son at a price far below the appraisals she never shared, then reports the sale in a single line of an annual accounting. That is self-dealing, concealment, and favoritism in one transaction, and each has its own remedy.

The business judgment rule and other defenses

Not every bad outcome is a breach, and Florida law gives fiduciaries real defenses. Anyone considering a claim, or defending one, should anticipate them:

• The business judgment rule. Florida courts will not second-guess an informed, good-faith business decision made by disinterested directors or managers, even one that turned out badly. The rule protects honest misjudgment; it does not protect self-interest, concealment, or decisions made without reasonable information.
• Authorization and ratification. A transaction fully disclosed to and approved by the disinterested owners or beneficiaries is difficult to attack later. Silence after full disclosure can also start limitation clocks running.
• Exculpation and statutory limits. Corporate directors enjoy the liability limits of Fla. Stat. § 607.0831, and operating agreements can lawfully narrow, though not eliminate, certain LLC duties under Fla. Stat. § 605.0105. The governing documents are always the first read.
• The independent tort doctrine. Where the parties’ relationship is defined purely by contract, Florida courts require a fiduciary claim to rest on duties independent of the contract’s terms. Some disputes that feel like betrayal are, legally, breach of contract cases, which we cover in our guide to breach of contract in Florida.
• The statute of limitations. Discussed below, and often the first motion a defendant files.

Direct claims versus derivative claims

When the fiduciary harmed a company, Florida law asks who really owns the claim. If the injury fell on the business itself, diverted profits, a wasted opportunity, looted accounts, the claim usually belongs to the company and must be brought derivatively on its behalf, under Fla. Stat. § 607.0741 for corporations and Fla. Stat. § 605.0802 for LLCs. Both require pre-suit demand on the company or a showing of futility, and any recovery generally flows to the entity, not the individual owner.

If the injury fell on you personally and directly, for example a freeze-out from distributions everyone else received, or fraud in the purchase of your interest, you may bring a direct claim in your own name. Getting this distinction right at the pleading stage matters enormously; choosing the wrong path can cost a year of motion practice. It is one of the first strategic calls we make in our complex commercial litigation practice.

What can you recover? Remedies and damages

Florida gives courts an unusually broad toolkit against a disloyal fiduciary:

• Compensatory damages for the losses the breach caused, including the value of diverted deals and mismanaged assets;
• Disgorgement of profits, forcing the fiduciary to surrender gains from the breach even where the beneficiary’s own loss is hard to measure;
• Constructive trust and equitable liens over property acquired with misappropriated funds, so specific assets can be traced and recovered;
• An accounting, compelling the fiduciary to open the books and justify every transaction;
• Removal, of a trustee under Fla. Stat. § 736.0706, of a personal representative under Fla. Stat. § 733.504, or of corporate control through receivership or judicial dissolution in appropriate cases;
• Injunctions to freeze assets or halt ongoing diversion while the case proceeds; and
• Punitive damages under Fla. Stat. § 768.72 where the conduct rises to intentional misconduct or gross negligence, a bar that egregious self-dealing can clear.

Valuing these claims is its own discipline. Diverted opportunities, suppressed distributions, and looted entities require forensic accounting and expert valuation, which is the focus of our financial damages practice. A fiduciary case pleaded without a credible damages model invites a low settlement; one built on traced dollars changes the negotiation.

The deadline: four years, and sometimes far less

Under Fla. Stat. § 95.11, a breach of fiduciary duty claim in Florida must generally be filed within four years. When the claim is founded on fraud, the clock can run from when the fraud was or should have been discovered, but Florida’s delayed-discovery doctrine is narrow, and courts apply it reluctantly outside the fraud context.

Three traps shorten the runway:

• Trust beneficiaries. Under Fla. Stat. § 736.1008, a trustee who serves a sufficient trust disclosure document with a limitation notice can cut the window to challenge a disclosed matter to as little as six months. Reading trustee correspondence carelessly can forfeit a claim before you know you have one.
• Probate. Estate administration runs on short, unforgiving objection deadlines measured in months, not years.
• Sitting on knowledge. A beneficiary who knew of the conduct and accepted its benefits invites ratification and laches defenses even inside the limitations period.

The safe assumption is always that your deadline is closer than it appears, and that the analysis should be done by counsel at the start, not the end.

What to do if you suspect a breach

1. Gather documents quietly. Agreements, amendments, account statements, tax returns, distribution records, and communications. Preserve everything, including your own files.
2. Use your inspection rights. Shareholders can demand corporate records under Fla. Stat. § 607.1602, LLC members under Fla. Stat. § 605.0410, partners under Fla. Stat. § 620.8403, and trust beneficiaries are entitled to accountings under Chapter 736. A refused records demand is itself evidence, and often the first exhibit.
3. Do not self-help. Freezing accounts, seizing property, or locking a co-owner out of the business can convert you from plaintiff to defendant.
4. Watch the calendar. Identify every limitations trigger, especially trustee disclosures and probate notices.
5. Get counsel involved early. The sequencing decisions, records demand, forensic review, injunction, then suit, determine whether assets are still there when judgment comes.

Frequently asked questions

What is a breach of fiduciary duty in Florida? It is the failure of someone who owes duties of loyalty and care, such as a business partner, corporate officer, LLC manager, trustee, or agent, to act in the interests of the person or entity they serve. Self-dealing, secret profits, diverted opportunities, and concealment are the classic forms.

What must I prove to win a breach of fiduciary duty case? Three elements: a fiduciary duty existed, the fiduciary breached it, and the breach proximately caused your damages. The duty can arise from a statute, a formal role, or a relationship of trust the other side accepted.

What is the statute of limitations for breach of fiduciary duty in Florida? Generally four years under Fla. Stat. § 95.11. But trust beneficiaries can face windows as short as six months after adequate trustee disclosures under Fla. Stat. § 736.1008, and probate deadlines are shorter still. Have the deadline analyzed early.

Is a business partner a fiduciary in Florida? Yes. Under Fla. Stat. § 620.8404, partners owe the partnership and each other duties of loyalty and care, including the duty to account for any personal benefit taken from partnership business. LLC managers and managing members owe comparable duties under Fla. Stat. § 605.04091.

What is the business judgment rule? A doctrine that shields informed, good-faith decisions by disinterested directors and managers from second-guessing in court. It protects honest mistakes. It does not protect conflicts of interest, self-dealing, or decisions made without reasonable diligence.

Can I recover punitive damages for breach of fiduciary duty? Sometimes. Under Fla. Stat. § 768.72, punitive damages require intentional misconduct or gross negligence, pleaded with a proffer of supporting evidence. Deliberate looting, concealment, and exploitation of vulnerable beneficiaries are the fact patterns that qualify.

What is the difference between a direct and a derivative claim? If the wrong injured the company, the claim usually belongs to the company and must be brought derivatively on its behalf, with any recovery flowing to the entity. If the wrong injured you personally and directly, you sue in your own name. Choosing correctly at the outset avoids costly motion practice.

Can a trustee be removed for breach of fiduciary duty? Yes. Florida courts can remove a trustee under Fla. Stat. § 736.0706 for serious breach, unfitness, or persistent failure to administer the trust effectively, and can surcharge the trustee for losses. Personal representatives face removal under Fla. Stat. § 733.504.
