Florida Breach of Fiduciary Duty Attorneys

When Someone Takes Advantage of Your Trust

Some disputes are about broken promises. Some are about bad judgment. A breach of fiduciary duty claim is different.

A fiduciary duty claim arises when one person or entity is legally required to act for the benefit of another person, business, beneficiary, investor, shareholder, partner, member, client, principal, or protected party—and instead uses that position for personal advantage, concealment, self-dealing, or disloyal conduct.

In plain English, Florida law recognizes that some relationships require more than ordinary honesty. Some people are trusted with money, property, business control, confidential information, decision-making authority, or legal power over someone else’s interests. When they abuse that power, the claim may be more serious than a contract dispute.

At Mockler Leiner Law, P.A., we represent individuals, businesses, business owners, shareholders, partners, LLC members, professionals, investors, beneficiaries, trustees, and property owners in Florida breach of fiduciary duty litigation. These cases often overlap with business tort litigation, shareholder and partner disputes, contract disputes, fraud litigation, civil theft claims, real estate litigation, and federal litigation.

We approach fiduciary duty cases as trial lawyers. The question is not simply whether the other side acted unfairly. The question is whether the evidence proves a legally recognized duty, a breach of that duty, causation, damages, and a remedy the court can actually award.

What Is a Breach of Fiduciary Duty Under Florida Law?

Under Florida law, the basic elements of a breach of fiduciary duty claim are:

• The existence of a fiduciary duty;

• A breach of that fiduciary duty; and

• Damages proximately caused by the breach.

The Florida Supreme Court described the claim this way in Gracey v. Eaker, 837 So. 2d 348, 353 (Fla. 2002), explaining that a breach of fiduciary duty claim requires the existence of a fiduciary duty and a breach of that duty that is a proximate cause of the plaintiff’s damages.

That sounds simple. It is not.

The hardest fight in many fiduciary duty cases is the first one: whether the defendant actually owed a fiduciary duty at all. Florida law does not treat every friendship, family relationship, business relationship, negotiation, lender relationship, or contract as fiduciary. A person can act badly, selfishly, aggressively, or dishonestly without automatically becoming a fiduciary.

A fiduciary relationship may be express or implied. Express fiduciary relationships may arise from recognized legal relationships such as trustee and beneficiary, principal and agent, guardian and ward, attorney and client, corporate officer and corporation, corporate director and corporation, partner and partnership, or other relationships created by agreement, statute, or legal status.

An implied fiduciary relationship depends on the facts. Florida courts have described a fiduciary relationship as one where confidence is reposed by one party and trust is accepted by the other. In Doe v. Evans, 814 So. 2d 370, 374 (Fla. 2002), and Taylor Woodrow Homes Florida, Inc. v. 4/46-A Corp., 850 So. 2d 536, 540 (Fla. 5th DCA 2003), Florida courts discussed fiduciary relationships in terms of trust, confidence, and acceptance of that trust.

The word “accepted” matters. A plaintiff usually cannot create a fiduciary duty simply by saying, “I trusted the defendant.” The defendant must have accepted, assumed, occupied, or acted within a role that Florida law recognizes as fiduciary in nature.

Breach of Fiduciary Duty Is Not the Same as Breach of Contract

Many fiduciary duty cases also involve a contract. There may be an operating agreement, shareholder agreement, partnership agreement, employment agreement, real estate contract, trust document, agency agreement, power of attorney, settlement agreement, or business purchase agreement.

But breach of fiduciary duty and breach of contract are not the same thing.

A contract claim usually asks: Did someone fail to do what the agreement required?

A fiduciary duty claim asks: Did someone with a heightened duty of loyalty, care, confidence, disclosure, or protection abuse that trusted position?

That distinction can matter for pleading, damages, defenses, settlement leverage, trial strategy, and remedies. A fiduciary duty claim may support remedies that do not fit neatly into an ordinary contract case, including disgorgement, accounting, constructive trust, injunctive relief, removal from a fiduciary role, equitable relief, or claims based on self-dealing and secret profits.

But the distinction also creates risk. If the alleged fiduciary duty is nothing more than a dressed-up contract obligation, the claim may be attacked. Florida courts often scrutinize attempts to turn ordinary contract disputes into tort claims. The pleading must identify the source of the fiduciary duty and the conduct that breached it.

Common Fiduciary Relationships in Florida Civil Litigation

Breach of fiduciary duty claims arise in many different Florida disputes. The specific relationship matters because the duties, defenses, remedies, and procedural rules may change depending on the context.

Business Partners and Partnerships

Florida partnership law recognizes fiduciary duties between partners. Section 620.8404, Florida Statutes, provides that partners owe duties of loyalty and care to the partnership and the other partners. The duty of loyalty includes accounting to the partnership for property, profit, or benefit derived from partnership business or use of partnership property; refraining from dealing with the partnership as an adverse party; and refraining from competing with the partnership before dissolution.

In practical terms, partnership fiduciary duty claims may involve a partner who diverts business, conceals income, misuses partnership money, takes a partnership opportunity, favors another business, hides books and records, or uses partnership property for personal gain.

LLC Members and Managers

Florida LLC fiduciary duty cases often require careful analysis of Chapter 605, the operating agreement, and whether the company is member-managed or manager-managed. Section 605.04091, Florida Statutes, addresses standards of conduct for members and managers. It provides fiduciary duties of loyalty and care for managers of manager-managed LLCs and members of member-managed LLCs.

The statutory duty of loyalty includes accounting to the LLC and holding as trustee for it property, profit, or benefit derived from company activities, use of company property, or appropriation of a company opportunity. It also includes refraining from adverse dealings with the company and refraining from competing with the company before dissolution.

LLC fiduciary duty claims often arise when one member controls the bank accounts, customer relationships, books, tax returns, leases, vendor relationships, or company opportunities. These cases can become urgent when money is moving, records are disappearing, or a member is using company assets to prepare a competing business.

Corporate Officers and Directors

Corporate officers and directors owe fiduciary obligations to the corporation and, in appropriate circumstances, its shareholders. In Cohen v. Hattaway, 595 So. 2d 105 (Fla. 5th DCA 1992), the court explained that corporate directors and officers owe fiduciary obligations and must act in good faith and in the best interests of the corporation.

Florida corporation law also includes statutory standards. Section 607.0830, Florida Statutes, requires directors to act in good faith and in a manner they reasonably believe to be in the best interests of the corporation, while discharging duties with appropriate care under the circumstances.

Corporate fiduciary duty claims may involve self-dealing, secret profits, excessive compensation, misuse of corporate funds, diversion of assets, improper related-party transactions, concealment from shareholders, or appropriation of corporate opportunities.

Trustees, Beneficiaries, and Estate-Related Disputes

Trustees owe serious fiduciary duties. Section 736.0801, Florida Statutes, requires a trustee to administer a trust in good faith, in accordance with the trust’s terms and purposes, in the interests of the beneficiaries, and in accordance with the Florida Trust Code. Section 736.0802, Florida Statutes, addresses the duty of loyalty and generally requires a trustee to administer the trust solely in the interests of the beneficiaries.

Trust-related fiduciary duty cases may involve self-dealing, failure to account, improper distributions, favoritism among beneficiaries, misuse of trust property, conflicts of interest, failure to preserve assets, unreasonable compensation, or transactions benefiting the trustee personally.

Some fiduciary duty cases involving trusts are handled in probate or trust litigation. Others overlap with civil litigation, real estate litigation, business disputes, family disputes, or financial exploitation claims.

Agents, Representatives, and People With Control Over Someone Else’s Money

Fiduciary duty claims may also arise from agency relationships. An agent who is authorized to act for someone else may owe duties within the scope of that agency. Those duties may include loyalty, care, obedience to lawful instructions, disclosure, accounting, and avoiding conflicts of interest.

These disputes may involve powers of attorney, business representatives, real estate agents, financial representatives, bookkeepers, escrow holders, employees with special authority, or people entrusted with funds for a specific purpose.

Not every employee is a fiduciary for every purpose. Not every business representative owes the same duty. The facts matter. The scope of authority matters. The documents matter. The money trail matters.

What Counts as a Breach of Fiduciary Duty?

A breach occurs when the fiduciary violates the duties owed within the scope of the relationship. The precise duty depends on the relationship, statute, agreement, and facts.

Common examples include:

• Self-dealing;

• Taking secret profits;

• Diverting business opportunities;

• Misusing company funds;

• Concealing conflicts of interest;

• Competing against the company while still owing duties;

• Using confidential information for personal advantage;

• Failing to disclose material facts;

• Failing to account for money or property;

• Transferring assets to insiders;

• Favoring one beneficiary or owner improperly;

• Paying unauthorized compensation;

• Using trust, company, or partnership property for personal purposes;

• Approving unfair transactions;

• Hiding books, records, tax returns, bank statements, or ledgers;

• Using control to freeze out a minority owner;

• Misrepresenting the financial condition of a business; or

• Helping another fiduciary conceal misconduct.

The law is not blind to subtle misconduct. Fiduciary breaches are often disguised as ordinary business decisions, compensation issues, reimbursements, related-party transactions, “loans,” consulting fees, management expenses, or undocumented transfers.

That is why the documents usually matter more than the speeches. Bank records, accounting files, emails, operating agreements, corporate minutes, QuickBooks data, tax returns, loan documents, closing statements, text messages, metadata, and third-party records often tell the real story.

Implied Fiduciary Duties and Arm’s-Length Business Deals

Some plaintiffs assume that unfair conduct automatically creates a fiduciary duty. Florida law is more demanding.

In Taylor Woodrow Homes Florida, Inc. v. 4/46-A Corp., the Fifth District emphasized that a breach of fiduciary duty claim is founded on a fiduciary relationship. Business parties negotiating at arm’s length generally do not become fiduciaries merely because one side has more knowledge, more experience, or more leverage.

Similarly, in banking and lender disputes, a bank normally does not owe fiduciary duties simply because it lends money, negotiates terms, protects collateral, or acts in its own financial interest. But special circumstances may change the analysis. In Capital Bank v. MVB, Inc., 644 So. 2d 515 (Fla. 3d DCA 1994), the court found evidence supporting a fiduciary duty where the bank’s conduct went beyond a typical lender relationship and the facts supported an implied fiduciary relationship.

The lesson is practical. Fiduciary duty claims should not be pled lazily. The complaint should identify what made the relationship fiduciary, what trust was accepted, what duty existed, how the duty was breached, and how that breach caused damage.

Direct Claims, Derivative Claims, and the Standing Trap

In shareholder, LLC, and closely held business disputes, one of the most important questions is whether the claim belongs to the individual owner or to the company.

This is not a technicality. It can decide whether the claim survives.

In Dinuro Investments, LLC v. Camacho, 141 So. 3d 731 (Fla. 3d DCA 2014), the Third District addressed the confusing distinction between direct and derivative claims in LLC disputes. The court explained that an individual member or shareholder may bring a direct action only when there is direct harm and a special injury separate and distinct from other owners, unless there is a separate contractual or statutory duty owed to the individual plaintiff.

If the injury is really an injury to the company—such as company funds being diverted, company assets being wasted, company opportunities being taken, or company value being reduced—the claim may need to be brought derivatively on behalf of the entity.

This distinction matters in fiduciary duty litigation involving:

• LLC member disputes;

• Shareholder disputes;

• Partnership breakups;

• Closely held corporations;

• Family-owned businesses;

• Professional practices;

• Real estate holding companies;

• Operating agreements;

• Deadlock and freeze-out claims; and

• Claims that one owner diverted value from the business.

A poorly framed claim can be dismissed even when the underlying misconduct is real. A strong fiduciary duty case must be brought by the right party, in the right capacity, with the right remedies.

That is one reason fiduciary duty claims often belong with broader shareholder and partner dispute litigation, not isolated pleading templates.

Damages and Remedies in Florida Fiduciary Duty Cases

The remedy depends on the breach. Some cases are about money. Some are about control. Some are about stopping ongoing harm. Some are about undoing transactions. Some are about forcing a fiduciary to account for what happened.

Potential remedies may include:

• Compensatory damages;

• Lost profits;

• Diminution in business value;

• Return of misappropriated funds;

• Disgorgement of profits;

• Accounting;

• Constructive trust;

• Injunctive relief;

• Removal of a fiduciary;

• Surcharge against a trustee or fiduciary;

• Rescission or unwinding of transactions;

• Recovery of diverted business opportunities;

• Recovery of improper compensation;

• Declaratory relief;

• Punitive damages in appropriate intentional misconduct cases; and

• Attorney’s fees when authorized by statute, contract, trust document, operating agreement, or other legal basis.

Damages can be straightforward when money was taken from an account. They become more complex when the misconduct caused lost customers, lost company value, loss of a business opportunity, tax consequences, financing problems, reputational harm, or litigation costs.

In many cases, the damages analysis requires forensic accounting, valuation evidence, bank record analysis, expert testimony, tax review, or industry-specific proof.

Emergency Relief in Fiduciary Duty Litigation

Some fiduciary duty cases cannot wait.

If a fiduciary is moving money, transferring assets, deleting records, competing with the company, misusing confidential information, selling property, diverting customers, or draining accounts, the client may need emergency relief before final judgment.

Possible emergency strategies may include temporary injunctions, preservation orders, expedited discovery, motions to compel access to books and records, receivership requests in appropriate cases, lis pendens in real estate-related matters, or narrowly tailored orders preventing further transfer or misuse of property.

Emergency relief requires evidence. Judges do not grant injunctions because a client is angry or suspicious. The moving party must be prepared to show facts, documents, witness testimony, irreparable harm where required, and a proposed order that is specific enough to enforce.

At Mockler Leiner Law, P.A., we look early at whether the case requires immediate action or whether a more measured litigation strategy will create better leverage.

Defenses to Breach of Fiduciary Duty Claims

Mockler Leiner Law, P.A. also defends individuals, fiduciaries, owners, professionals, businesses, trustees, managers, officers, directors, and agents accused of breach of fiduciary duty.

Not every accusation is valid. Fiduciary duty claims are sometimes used as leverage in business breakups, family disputes, shareholder fights, trust conflicts, divorce-related business disputes, and post-transaction litigation.

Common defenses may include:

• No fiduciary duty existed;

• The relationship was an arm’s-length transaction;

• The defendant did not accept fiduciary responsibilities;

• The alleged duty was outside the scope of the relationship;

• The claim is really a contract claim;

• The plaintiff cannot prove breach;

• The plaintiff cannot prove causation;

• The damages are speculative;

• The claim belongs to the company and must be brought derivatively;

• The plaintiff lacks standing;

• The transaction was authorized, disclosed, ratified, or fair;

• The plaintiff consented to the conduct;

• The business judgment rule or statutory reliance defenses apply;

• The operating agreement, partnership agreement, corporate documents, or trust document modifies the analysis;

• The statute of limitations bars the claim;

• The plaintiff failed to mitigate damages;

• The plaintiff has unclean hands; or

• The plaintiff is using fiduciary duty language to inflate a business dispute.

A strong defense begins with narrowing the alleged duty. Fiduciary duties are not unlimited. A fiduciary is not automatically liable for every loss, bad result, failed investment, business downturn, market condition, or disagreement.

The Statute of Limitations for Breach of Fiduciary Duty in Florida

Many Florida breach of fiduciary duty claims are subject to a four-year statute of limitations. Section 95.11(3), Florida Statutes, contains several four-year limitation provisions that may apply depending on how the claim is characterized.

Limitation issues in fiduciary duty cases can be dangerous because misconduct is often hidden. Clients sometimes assume the clock does not start until they discover the wrongdoing. That assumption can be wrong.

In Davis v. Monahan, 832 So. 2d 708 (Fla. 2002), the Florida Supreme Court refused to broadly apply the delayed discovery doctrine to claims including breach of fiduciary duty, conversion, civil conspiracy, and unjust enrichment. The Court emphasized that delayed discovery is limited to specific categories recognized by statute or narrow case law.

That does not mean every limitations defense will win. Accrual, concealment, fraud, continuing conduct, trust accountings, statutory claims, equitable tolling arguments, and the precise nature of the claim may all matter. But it does mean that waiting can destroy a claim.

If a fiduciary duty issue involves missing money, hidden transfers, trust property, business assets, company records, investment funds, or real estate, legal advice should be obtained quickly.

Fiduciary Duty Claims Often Overlap With Other Claims

A breach of fiduciary duty claim rarely travels alone. Depending on the facts, the same conduct may support or relate to other claims, including:

• Fraud;

• Civil theft;

• Conversion;

• Breach of contract;

• Tortious interference;

• Unjust enrichment;

• Accounting;

• Constructive trust;

• Civil conspiracy;

• Aiding and abetting breach of fiduciary duty;

• FDUTPA;

• Trade secret misappropriation;

• Real estate claims;

• Derivative claims;

• Business dissolution; or

• Injunctive relief.

The strongest case is not always the one with the most counts. Overpleading can create credibility problems, fee exposure, dismissal risk, and unnecessary complexity. Underpleading can leave remedies on the table.

The strategy should begin with the evidence and the remedy. What happened? Who owed the duty? Who was harmed? Who owns the claim? What relief will actually fix the problem?

Fiduciary Duty in Real Estate, Investment, and Business Sale Disputes

Florida fiduciary duty claims frequently arise in real estate and investment disputes. These cases may involve agents, managers, brokers, investors, joint venturers, escrowed funds, development opportunities, rental income, closing proceeds, property management, or related-party transactions.

A fiduciary duty issue may arise when someone entrusted with a property opportunity secretly takes it, moves proceeds, manipulates ownership, conceals a buyer, diverts rent, misuses escrow funds, or fails to disclose a conflict.

But not every real estate or investment relationship is fiduciary. A buyer and seller negotiating a real estate contract are usually adverse parties, not fiduciaries. A lender protecting its loan is usually acting for itself. A business buyer conducting due diligence is not automatically a fiduciary for the seller.

The line between hard bargaining and fiduciary misconduct can determine the case.

Mockler Leiner Law, P.A. handles real estate litigation and business disputes where fiduciary duties intersect with contracts, ownership, title, fraud, financing, and control.

Why Fiduciary Duty Cases Require Trial Judgment

Breach of fiduciary duty cases are fact-heavy. The other side may argue that the transaction was authorized, the plaintiff knew everything, the money was a loan, the payment was compensation, the opportunity did not belong to the company, the business was already failing, or the plaintiff is simply trying to rewrite a bad deal.

These cases often turn on credibility and motive.

The court may need to understand why a transaction was structured a certain way, why money moved when it did, why records were missing, why a fiduciary did not disclose a conflict, why company funds were used for personal benefit, or why a supposed “business judgment” conveniently benefited the person in control.

Richard J. Mockler brings a background in complex civil litigation, financial disputes, business litigation, securities-related issues, banking litigation, and tax. His work has included high-stakes commercial cases, derivative litigation, federal litigation, and matters involving sophisticated financial records.

Angela L. Leiner brings substantial civil litigation, real property litigation, banking litigation, contract, fraud, business dispute, and courtroom experience. Her background in economics and courtroom-heavy litigation is especially valuable in cases where money, documents, and credibility collide.

Together, Mockler Leiner Law, P.A. brings trial experience and financial sophistication to fiduciary duty disputes. These cases reward lawyers who can read the documents, understand the numbers, prepare witnesses, cross-examine carefully, and explain complicated misconduct in a way that makes sense.

Our Approach to Breach of Fiduciary Duty Cases

We do not assume that every betrayal is a fiduciary duty claim. We also do not assume that every fiduciary can hide behind paperwork.

Our analysis usually begins with these questions:

• What relationship created the alleged fiduciary duty?

• Was the duty express, statutory, contractual, implied, or based on legal status?

• What was the exact scope of the duty?

• What conduct allegedly breached the duty?

• Was the conduct authorized, disclosed, concealed, ratified, or disputed?

• Who was harmed—the individual, the company, the trust, the partnership, or someone else?

• Is the claim direct or derivative?

• What records prove the money trail?

• Are emergency remedies needed?

• Are damages measurable?

• Are equitable remedies available?

• Are attorney’s fees available?

• Is the defendant collectible?

• Are there related claims for fraud, civil theft, conversion, tortious interference, or breach of contract?

• Should the dispute be in state court, federal court, arbitration, probate court, or business litigation?

The answers shape the case.

A fiduciary duty lawsuit should not be filed as a generic accusation of betrayal. It should be built as a proof-driven claim with a clear theory of duty, breach, causation, damages, and remedy.

Frequently Asked Questions About Florida Breach of Fiduciary Duty Claims

What is a fiduciary duty in Florida?

A fiduciary duty is a legal duty requiring one person or entity to act for the benefit of another within the scope of a trusted relationship. Fiduciary duties may arise from formal legal relationships, statutes, contracts, agency, business control, trust relationships, or special facts showing that confidence was reposed and accepted.

What are the elements of breach of fiduciary duty in Florida?

The core elements are the existence of a fiduciary duty, breach of that duty, and damages proximately caused by the breach. The plaintiff must prove more than unfairness. The plaintiff must prove a legally recognized duty and a causal connection between the breach and the harm.

Is every business partner a fiduciary?

Partners generally owe fiduciary duties under Florida partnership law. LLC members and managers require a more careful analysis under Chapter 605, the operating agreement, and whether the LLC is member-managed or manager-managed. Corporate officers and directors also owe fiduciary obligations. The exact duty depends on the entity structure and governing documents.

Can I sue my business partner directly for breach of fiduciary duty?

Maybe. In Florida, some owner claims must be brought directly, while others must be brought derivatively on behalf of the company. If the injury was suffered by the company first, the claim may belong to the company. If the owner suffered a direct and special injury, or if a separate contractual or statutory duty was owed to that owner, a direct claim may be possible. This issue should be analyzed before filing.

What is self-dealing?

Self-dealing occurs when a fiduciary uses a trusted position to benefit personally at the expense of the person, company, partnership, trust, or beneficiary to whom duties are owed. Examples may include taking company opportunities, paying unauthorized compensation, transferring assets to insiders, buying property from the entity on unfair terms, or secretly profiting from a transaction.

Can breach of fiduciary duty support punitive damages?

In appropriate cases involving intentional misconduct, fraud, malice, or other conduct meeting Florida’s punitive damages standards, punitive damages may become an issue. They are not automatic. Florida has specific pleading and procedural requirements for punitive damages, and the facts must justify that remedy.

What damages are available for breach of fiduciary duty?

Damages may include lost money, lost profits, lost business value, return of misappropriated funds, disgorgement, accounting, constructive trust, injunction, removal of a fiduciary, surcharge, or other legal and equitable remedies. The remedy depends on the breach, the relationship, the documents, and the proof.

How long do I have to bring a breach of fiduciary duty claim in Florida?

Many breach of fiduciary duty claims are subject to a four-year statute of limitations, but limitation issues can be fact-specific. Do not assume the clock starts only when the misconduct is discovered. Florida law does not broadly apply delayed discovery to every fiduciary duty claim.

Is breach of fiduciary duty the same as fraud?

No. Fraud generally involves false statements, concealment, reliance, and damages. Breach of fiduciary duty focuses on abuse of a fiduciary relationship. The same facts may support both claims in some cases, but the elements and defenses are different.

Can a fiduciary duty claim be based on concealment?

Yes, in appropriate cases. A fiduciary may have duties of disclosure, loyalty, accounting, or candor depending on the relationship. Concealing conflicts, transactions, profits, transfers, or material facts may support a fiduciary duty claim when the defendant had a duty to disclose.

Can fiduciary duty claims involve family members?

Sometimes. Family relationship alone does not always create a fiduciary duty. But fiduciary duties may arise when a family member serves as trustee, agent under a power of attorney, business manager, personal representative, guardian, company officer, or person entrusted with control over money or property.

Do I need emergency court action for a fiduciary duty case?

Possibly. If money is being moved, property is being transferred, records are disappearing, confidential information is being used, or business opportunities are being diverted, emergency remedies may need to be considered quickly. The need for emergency relief depends on the facts and available evidence.

Speak With a Florida Breach of Fiduciary Duty Attorney

Breach of fiduciary duty cases are about power, trust, money, and proof. The person who controlled the records may also be the person accused of hiding the truth. The person who owed loyalty may be the person who quietly profited. The sooner the evidence is preserved, the stronger the case may become.

Mockler Leiner Law, P.A. represents plaintiffs and defendants in serious Florida fiduciary duty litigation, including business disputes, shareholder and partner disputes, LLC litigation, trustee disputes, real estate disputes, financial misconduct claims, fraud cases, civil theft claims, and related business tort litigation.
