When you place your trust and confidence in another person or entity to act in your interests, the law imposes a serious obligation on that party to honor it. That obligation is a fiduciary duty, one of the highest standards of conduct New York law recognizes. When a fiduciary betrays the trust — through self-dealing, mismanagement, dishonesty or negligence — the person harmed has legal remedies, and the fiduciary has exposure that can reach beyond the loss actually caused.
We represent individuals, businesses, beneficiaries, shareholders and investors who need to hold a fiduciary accountable: a dishonest business partner, a self-serving corporate officer, an unfaithful trustee, a financial advisor who put their own interests first. We also defend fiduciaries who have been wrongly accused. This page explains what the duty is, who owes it, what a claim requires, what a court can order, and how long you have to act.
What Is a Fiduciary Duty Under New York Law?
A fiduciary duty is a legal obligation requiring one party to act in the best interests of another.
New York courts recognize a fiduciary relationship where one party reposes trust and confidence in another, who in turn assumes a position of superior knowledge, influence or control. The fiduciary must set aside personal interests and act with complete loyalty and good faith toward the person served. New York law generally treats that obligation as having two core components. The duty of loyalty requires the fiduciary to act solely in the interest of the beneficiary: no self-dealing, no secret profits, no personal interests allowed to conflict with the obligation. The duty of care requires the fiduciary to carry out their responsibilities with the diligence, prudence and competence a reasonable person would exercise in similar circumstances.
The New York Court of Appeals has long described the standard in demanding terms. In Meinhard v. Salmon, the court explained that a fiduciary is held to something stricter than the morals of the marketplace — not honesty alone, but the most sensitive standard of honor and loyalty. That standard continues to govern fiduciary relationships throughout New York today.
Common Fiduciary Relationships in New York
Some relationships are fiduciary as a matter of law; others depend on the facts and the degree of trust placed in one party.
| Fiduciary | Owes the duty to | Scope |
|---|---|---|
| Business partners | Each other | Loyalty, good faith and full disclosure regarding partnership affairs. |
| Corporate officers and directors | The corporation and its shareholders | Avoiding self-dealing and acting in the company’s best interest. |
| Majority shareholders | Minority shareholders | In closely held corporations, controlling shareholders may owe fiduciary duties to the minority. |
| LLC members and managers | The company and other members | Depends on the operating agreement and the structure of the company. |
| Trustees and executors | Beneficiaries | Strict fiduciary duties in administering the trust or estate. |
| Agents and brokers | Their principals | Real estate brokers, insurance agents and other agents. |
| Attorneys | Clients | Loyalty and confidentiality. |
| Financial advisors and investment managers | Clients whose money they manage | May owe an obligation to act in the client’s best interests. |
| Guardians | Their wards | Managing the affairs of an incapacitated person. |
If it is not clear whether a fiduciary relationship existed in your situation, that question is usually the first one we analyze, because the rest of the claim depends on it.
Elements of a Breach of Fiduciary Duty Claim
A plaintiff in New York generally must establish three elements.
- 1
A fiduciary relationship
The defendant owed you a fiduciary duty, either as a matter of law or because of the relationship of trust and confidence between you.
- 2
Misconduct by the fiduciary
The fiduciary breached the duty through wrongful conduct: self-dealing, a conflict of interest, mismanagement, concealment, or a failure to act with the required care and loyalty.
- 3
Damages caused by the breach
The breach directly caused you harm, whether financial loss, a lost opportunity or other quantifiable damage.
Whether these elements are met turns on the facts of each case. Fiduciary claims typically involve financial records, business transactions and questions of intent, so the investigation matters as much as the legal argument.
Examples of Breach of Fiduciary Duty
Breaches take many forms. These are the ones we see most often.
| Breach | What it looks like |
|---|---|
| Self-dealing | The fiduciary uses the position to enter into transactions that benefit themselves at the expense of the person they serve. |
| Misappropriation of assets | The fiduciary takes money or property belonging to the beneficiary, partnership or corporation for personal use. |
| Usurping a business opportunity | A corporate officer or partner takes for themselves an opportunity that rightfully belonged to the company. |
| Conflict of interest | The fiduciary fails to disclose a personal interest that conflicts with the obligation. |
| Mismanagement | A trustee, officer or manager handles assets recklessly or negligently, causing losses. |
| Failure to disclose | The fiduciary conceals material facts the beneficiary was entitled to know. |
| Commingling funds | The fiduciary mixes their own money with the funds they were entrusted to protect. |
| Excessive compensation | An officer or fiduciary pays themselves unreasonable amounts at the expense of the company or the beneficiaries. |
| Fraud and deception | Dishonest conduct that harms the person who trusted the fiduciary. |
Remedies for Breach of Fiduciary Duty in New York
The remedy depends on the nature of the breach and the harm suffered; several can be sought together.
The most straightforward remedy is compensatory damages: money for the actual financial loss the breach caused. But fiduciary law goes further than ordinary damages. A court can order disgorgement, forcing the fiduciary to hand over any profit wrongfully obtained even where the beneficiary cannot prove direct damages, on the principle that a fiduciary should not profit from disloyalty. It can impose a constructive trust over assets the fiduciary wrongfully holds, requiring them to be held for the rightful owner. It can order an accounting — a detailed statement of every transaction — to establish the extent of the wrongdoing, and it can grant an injunction to stop ongoing or threatened breaches.
Where the fiduciary holds an office, the court can remove them: a trustee, an executor or another fiduciary can be taken out of the position in an appropriate case. And where the misconduct is particularly egregious, malicious or willful, New York courts may award punitive damages to punish the wrongdoer and deter similar conduct.
The faithless servant doctrine deserves special mention. When an employee or agent acts disloyally, New York law may require them to forfeit all compensation received during the period of disloyalty, regardless of whether the employer suffered actual damages. In the right case that forfeiture is a substantial recovery on its own.
In the estate and trust context, our pages on whether a beneficiary can sue a trustee, estate accountings and removing an executor or trustee under SCPA 711 go into how these remedies play out in the Surrogate’s Court.
Statute of Limitations for Fiduciary Duty Claims in New York
The time limit depends on the type of relief sought, because New York has no single limitations period written specifically for fiduciary claims.
Courts look at the substance of the claim and the remedy requested. Generally, where the relief sought is purely monetary, a three-year statute of limitations applies. Where the relief is equitable in nature, a six-year period may apply. Claims based on actual fraud may also be governed by a six-year period, with a discovery rule that can allow the claim to be brought within two years after the fraud was discovered or could have been discovered with reasonable diligence.
Working out the right period is fact-specific, and waiting too long can permanently end the right to recover. The practical rule is to get advice as soon as you suspect a breach, so that the claim is framed and filed within whichever deadline applies.
Defenses to Breach of Fiduciary Duty Claims
A fiduciary accused of a breach has several recognized defenses, and a claimant should expect to meet them.
| Defense | The argument |
|---|---|
| No fiduciary relationship | The relationship was an arm’s length business transaction that did not give rise to fiduciary obligations. |
| Consent or ratification | The beneficiary consented to the conduct, or ratified it afterwards, particularly where there was full disclosure. |
| Business judgment rule | Corporate officers and directors are protected for good-faith business decisions made in the honest belief that they were in the company’s best interest. |
| Statute of limitations | The claim was filed too late. |
| No damages | The plaintiff suffered no actual harm from the alleged breach. |
Whether we are bringing the claim or defending it, these defenses shape the case from the start: the facts we develop and the documents we gather are chosen with them in mind.
Who Can Bring a Breach of Fiduciary Duty Claim?
Standing follows the relationship: whoever was owed the duty can sue on it.
That includes minority shareholders harmed by controlling shareholders or corporate insiders, business partners harmed by another partner, LLC members harmed by managers or other members, beneficiaries of trusts and estates harmed by trustees or executors, clients harmed by attorneys, financial advisors or other professionals, investors harmed by investment managers, and corporations seeking to recover from disloyal officers, directors or employees. Where the fiduciary is a shareholder or corporate insider, our shareholder disputes page covers the corporate side in more detail.
In some situations, particularly those involving corporations, the claim has to be brought derivatively on behalf of the company rather than directly by an individual. Choosing the right way to assert the claim is a strategic decision made at the outset, and getting it wrong can cost the case.
How We Handle These Cases
Fiduciary cases turn on financial analysis, business records and, often, expert testimony.
We begin by evaluating whether a fiduciary relationship existed and whether a breach occurred, then obtain and review the financial records, communications and other evidence needed to prove or disprove it. From there we build a strategy aimed at the best realistic outcome, whether by negotiation, settlement or trial, and where litigation is necessary we pursue every remedy New York law allows, including compensatory damages, disgorgement, forfeiture and equitable relief. We represent both sides of these disputes — beneficiaries, shareholders, partners and investors bringing claims, and fiduciaries defending against them.
