What Is a Breach of Fiduciary Duty in a Florida Business?

A breach of fiduciary duty in a Florida business happens when someone who is legally obligated to put the company’s interests ahead of their own does the opposite, and the company or its owners lose money as a result. Think of a manager who quietly routes a profitable contract to a side venture, a director who approves a lease with a company she secretly owns, or a partner who takes the customer list on the way out the door.

The label matters more than most business owners expect. Fiduciary claims carry remedies that ordinary contract claims do not, including disgorgement of profits, constructive trusts, and in some cases punitive damages. They also carry a higher bar than many claimants assume.

Who Owes Fiduciary Duties in a Florida Business?

Fiduciary duties attach to people in positions of trust and control, and Florida law identifies most of them by statute. If someone manages other people’s money or governs a company they do not solely own, assume a fiduciary duty exists until an attorney tells you otherwise.

Corporate Officers and Directors

Under section 607.0830, Florida Statutes, each director must act in good faith and in a manner he or she reasonably believes to be in the best interests of the corporation. The same statute requires directors to exercise “the care that an ordinary prudent person in a like position would reasonably believe appropriate under similar circumstances.”

Officers owe parallel duties of loyalty and care. Both roles sit at the center of most breach of fiduciary duty claims against an officer, director, or manager.

LLC Members and Managers

Section 605.04091, Florida Statutes states that each manager of a manager-managed LLC and each member of a member-managed LLC owes fiduciary duties of loyalty and care to the company and its members.

The duty of care under that statute is narrower than the corporate standard. It requires only that the member or manager “refrain from engaging in grossly negligent or reckless conduct, willful or intentional misconduct, or a knowing violation of law.” Ordinary bad judgment usually is not enough. Your operating agreement can also modify some of these obligations, which is why the document controls the analysis more often than people realize.

Partners

Section 620.8404, Florida Statutes limits a partner’s fiduciary duties to loyalty and care, and it spells out what loyalty means: account to the partnership for any benefit derived from partnership property or a partnership opportunity, avoid dealing with the partnership on behalf of an adverse party, and refrain from competing with the partnership before dissolution.

Note subsection (5). A partner does not breach a duty “merely because the partner’s conduct furthers the partner’s own interest.” Self-interest alone is not a claim.

Trusted Outsiders

Fiduciary duties are not limited to owners and managers. Florida courts recognize relationships implied in law based on the facts. In Capital Bank v. MVB, Inc., the Third District held that a bank owed a fiduciary duty to a borrower where the bank “knows or has reason to know of the customer’s trust and confidence under circumstances exceeding an ordinary commercial transaction.”

That principle reaches accountants, brokers, agents, and consultants. It can also reach lenders in an otherwise ordinary borrower relationship when the lender voluntarily steps into an advisory role.

What Does a Breach Actually Look Like?

Most breaches fall into a handful of recognizable patterns. The common thread is a fiduciary capturing value that belonged to the company or its owners.

• Self-dealing. Approving transactions with entities the fiduciary secretly controls, or on terms no arm’s-length counterparty would accept.
• Diverting company funds. Misappropriation or embezzlement of company funds, including personal expenses run through the business.
• Usurping company opportunities. Taking a deal that came to the fiduciary because of their role and keeping it for a personal venture.
• Competing while still inside. Building a competing business on company time, using company relationships, or misappropriating trade secrets and customer data.
• Concealing material information. Withholding facts owners need to vote, sell, or protect their investment.
• Freeze-outs and oppression. Cutting off distributions, information, or employment to squeeze out a minority holder, a recurring feature of majority versus minority shareholder disputes.
• Neglect rising to gross negligence. Mismanagement of company assets severe enough to clear the statutory threshold.

What Do You Have to Prove?

Florida courts require three things: a fiduciary duty existed, the fiduciary breached it, and the breach proximately caused damages. Cases are usually won or lost on the first element and the third, not the second.

The first element is the most contested. A plaintiff who cannot point to a statute or a governing document has to prove the relationship was implied in law, and that requires evidence of real dependence, not just disappointed trust.

The third element trips up otherwise strong cases. Proving the fiduciary behaved badly is not the same as proving the company lost a quantifiable amount because of it. Expect to need financial records, valuation testimony, and often an equitable accounting to trace where the money went.

How Does the Business Judgment Rule Change the Analysis?

The business judgment rule protects informed, good-faith decisions even when they turn out badly. It is the single biggest obstacle to a claim against a director.

Section 607.0831, Florida Statutes says a director is not personally liable for monetary damages for a decision or a failure to act unless the director both breached a duty and that breach constituted one of several specific things: a violation of criminal law, a transaction from which the director derived an improper personal benefit, an unlawful distribution under section 607.0834, conscious disregard for the corporation’s best interest, willful or intentional misconduct, or in third-party suits, recklessness or bad faith.

Read that as a filter: a claim that amounts to “the board made a bad call” will not survive, but a claim built on self-interest, concealment, or conscious disregard can. Our discussion of the business judgment rule and director liability walks through how Florida courts apply the standard in practice.

Who Owns the Lawsuit, the Company or the Owner?

If the harm ran to the company, the claim usually belongs to the company and must be brought as a derivative action. If the harm ran to an owner personally, the claim can be brought directly.

Getting this wrong is fatal early. Derivative claims carry procedural prerequisites, including a written demand on the board and standing requirements, which is why shareholder derivative lawsuits get dismissed on process grounds more often than on merits. Direct claims typically arise where the fiduciary breached a member, shareholder, or partner agreement or targeted one owner specifically.

The distinction gets blurry in closely held and family-owned businesses, where the company and its owners are practically the same people. Florida courts have allowed direct claims in that setting where the injury was distinct from the company’s.

What Remedies Are Available?

Fiduciary claims unlock equitable relief that contract claims generally do not. The remedy set is the main reason to plead a fiduciary theory when the facts support one.

1. Compensatory damages for the company’s or owner’s proven loss.
2. Disgorgement of profits the fiduciary earned through the breach.
3. A constructive trust imposed on specific assets or proceeds traceable to the breach.
4. Injunctive relief to stop ongoing conduct, freeze assets, or preserve records.
5. Removal of the fiduciary, or in severe cases, judicial dissolution.
6. Claims against third parties who helped, through aiding and abetting or civil conspiracy theories.

Where the conduct involved outright theft of money or property, a civil theft count can add treble damages and fees, though the statutory notice requirements are strict.

How Long Do You Have to Sue?

Most breach of fiduciary duty claims in Florida are governed by a four-year limitations period, but the deadline shifts based on how the claim is framed. Claims sounding in negligence now carry a shorter window after the 2023 amendments, and trust and probate contexts have their own, much shorter clocks.

Do not treat four years as a safe assumption. Our detailed analysis of the statute of limitations for breach of fiduciary duty in Florida explains how the framing of the claim changes the deadline.

What Defenses Should You Expect?

Defendants in these cases have a well-worn playbook, and it works often enough to take seriously.

• No fiduciary relationship existed. The most effective defense, because it ends the case rather than narrowing it.
• The governing document authorized it. Articles, operating agreements, and partnership agreements frequently permit conflicted transactions after disclosure and approval.
• Ratification or consent. Owners who approved the transaction, or accepted its benefits while informed, have a hard time complaining later.
• Business judgment. Informed, good-faith decisions are protected even when they lose money.
• No causation or no damages. Bad conduct that did not cause a measurable loss does not support recovery.
• Time-barred. Limitations and laches defenses, which is why documenting your discovery date matters.

What Should a Florida Business Owner Do First?

Move on documentation before you move on litigation. Fiduciary cases are won with records, and records disappear once the other side knows a claim is coming.

1. Secure the governing documents, board and member minutes, and any buy-sell agreement.
2. Preserve email, messaging, and accounting data, and suspend any automatic deletion.
3. Build a timeline of the transactions at issue, including who knew what and when.
4. Assess whether the claim is direct or derivative before sending any demand.
5. Consider whether a restrictive covenant or unfair competition claim travels alongside the fiduciary claim.

If you are on the receiving end, the analysis runs in reverse. Identify whether a fiduciary duty existed at all, then whether the governing documents, disclosure, or owner approval insulate the transaction.
