A New York business relationship becomes a fiduciary one when a party is entitled to rely on the other to act for that party’s benefit, not merely to perform a bargain. Partners, managing LLC members, and corporate officers carry that duty. Arm’s length counterparties usually do not. That single line decides most of these cases.
You have been served with a complaint that says you betrayed someone’s trust. The word “fiduciary” is doing a lot of work in that pleading. Make the plaintiff prove it.
When does a business relationship become a fiduciary relationship in New York?
A fiduciary relationship exists in New York when one person is under a duty to act for, or to give advice for the benefit of, another on matters within the scope of the relation. The inquiry is fact specific: trust reposed on one side, resulting superiority and influence on the other. Arm’s length dealing alone creates no duty.
Authority: EBC I, Inc. v Goldman, Sachs & Co., 5 NY3d 11, 19-20 (2005); Northeast Gen. Corp. v Wellington Adv., 82 NY2d 158, 162-164 (1993).
Control, dominance, and dependence are what courts look for, but no single one is a required element. The rule is about function, not vocabulary. In Northeast General, the Court of Appeals held that a fiduciary-like duty turns not on the label “finder” or “broker” or even “agent,” but on the services the parties agreed to under their contract. Calling someone a partner in an email does not make him one. Calling yourself a consultant does not save you if you controlled the books, the bank account, and the information the other side relied on.
Apply that to the complaint in front of you. It calls you a partner, says the plaintiff trusted you, and says you took an opportunity for yourself. The court will ask what you were retained or organized to do, and whether the plaintiff surrendered control to you. If both sides dealt at arm’s length and each kept his own lawyer and accountant, the duty ordinarily does not attach.
| Relationship | Default position on fiduciary duty | Where the defense usually lives |
|---|---|---|
| General partners | Duty applies by statute. A partner must account for any benefit and hold as trustee any profit taken without the consent of the other partners. | Whether a partnership existed at all, and whether the other partners consented. |
| Managing member or manager of an LLC | Duty applies, including to non-managing members. | Whether you actually managed, and whether the operating agreement allowed the act. |
| Corporate officer or director | Loyalty and care run to the corporation. A controlling shareholder may also owe duties to the minority. | Whether the plaintiff shareholder can sue directly rather than derivatively. |
| Contract counterparty at arm’s length | Ordinarily no duty. The contract sets the obligation. | Showing the complaint describes nothing beyond the contract. |
| Advisor outside the written deal | Duty may exist if a relationship of higher trust arose apart from the contract. | Confining the role to what the signed document defines. |
Law: Partnership Law 43; Business Corporation Law 717.
Do LLC members and managers owe fiduciary duties to each other?
An LLC manager in New York must perform his duties in good faith and with the degree of care an ordinarily prudent person in a like position would use under similar circumstances. Managing members owe a fiduciary duty to non-managing members. A member who manages nothing is a weaker target, but not automatically immune.
Law: Limited Liability Company Law 409(a).
Authority: Pokoik v Pokoik, 115 AD3d 428, 429 (1st Dept 2014).
The statute also gives you a defense most complaints ignore. A manager may rely on information, opinions, reports and statements prepared by the company’s employees, by counsel, and by public accountants on matters within their professional competence.
Law: Limited Liability Company Law 409(b).
So the sequence matters. If you approved a distribution after your accountant said the company could afford it, the statute contemplates that reliance. The protection is not unconditional. It assumes good faith and does not cover reliance on a report you knew was wrong. The plaintiff must attack your good faith, not the outcome. Bad results are not breaches.
What does a plaintiff actually have to prove?
A breach of fiduciary duty claim in New York requires three things: a fiduciary relationship between the parties, misconduct by the defendant, and damages directly caused by that misconduct. Each element is a separate point of attack. Test all three. The first and the third are frequently the softer targets.
Take damages. The plaintiff must tie a dollar figure to your conduct, not to the market or to his own decision to stop funding. If the venture failed for reasons the complaint describes, causation is contested.
Take the demand for an accounting. As a general rule, a claimant must show he has no adequate remedy at law, so his parallel money claim is worth pressing. Do not overstate it. Where a fiduciary relationship is established, courts have allowed a common-law accounting even though a contract remedy exists. This is an argument, not a certainty.
Authority: Unitel Telecard Distrib. Corp. v Nunez, 90 AD3d 568, 569 (1st Dept 2011); Gottlieb v Northriver Trading Co. LLC, 58 AD3d 550, 551 (1st Dept 2009).
Does CPLR 3016(b) require the complaint against me to be pleaded in detail?
Usually yes. CPLR 3016(b) requires that where a claim is based on misrepresentation, fraud, mistake, willful default, breach of trust or undue influence, the circumstances constituting the wrong be stated in detail. New York courts apply that requirement to breach of fiduciary duty claims that sound in fraud or breach of trust. Its reach beyond those claims varies.
Law: CPLR 3016(b).
Authority: Palmetto Partners, L.P. v AJW Qualified Partners, LLC, 83 AD3d 804, 808 (2d Dept 2011).
The standard is not impossible to meet. The Court of Appeals has held that CPLR 3016(b) is satisfied when the alleged facts permit a reasonable inference of the misconduct, and that it should not be read so strictly as to defeat a valid claim where the details sit in the defendant’s own files.
Authority: Pludeman v Northern Leasing Sys., Inc., 10 NY3d 486, 491-492 (2008).
But a reasonable inference is still an inference from stated facts. In Eurycleia, the Court of Appeals affirmed dismissal because the allegations, taken with the surrounding circumstances, raised no reasonable inference of the wrongdoing charged. Conclusory assertions were not rescued by volume.
Authority: Eurycleia Partners, LP v Seward & Kissel, LLP, 12 NY3d 553, 559-561 (2009).
So read the complaint with a pen. Which transaction? What date? What was diverted, and to where? A pleading that says you “engaged in self-dealing and usurped company opportunities” over four years, without naming one transaction, has not stated the circumstances in detail. That is your particularity motion. Expect a request for leave to replead, and expect Pludeman in response.
Particularity is not a technicality. It is the difference between a complaint that states a claim and a complaint that states a suspicion.
How long does someone have to sue me for breach of fiduciary duty in New York?
There is no single limitations period for breach of fiduciary duty in New York. The Court of Appeals has held that claims seeking money damages carry three years, and claims seeking equitable relief six years. Where actual fraud is essential to the claim, six years applies. The remedy sought controls, not the label.
Authority: IDT Corp. v Morgan Stanley Dean Witter & Co., 12 NY3d 132, 139 (2009).
| What the plaintiff seeks | Period | What you check first |
|---|---|---|
| Money damages only | Three years | The earliest act described, not the date he says he found out. Then check for tolling. |
| Equitable relief, such as rescission, a constructive trust, or an accounting | Six years | Whether the equitable demand is real or decorative, added to buy three years. |
| Fiduciary claim where actual fraud is essential | Six years from the wrong, or two years from discovery, whichever is longer | Whether every element of fraud is pleaded, including justifiable reliance, and whether the fraud allegations are merely incidental. |
Authority: Kaufman v Cohen, 307 AD2d 113, 118-119 (1st Dept 2003).
That third row is where cases are won. A plaintiff out of time on three years will often add the word “fraud” to reach six. The word alone does not do it. Where the fraud allegations are incidental, or an element such as justifiable reliance is missing, three years applies and an old monetary claim is untimely.
Accrual is the other half. A breach of fiduciary duty claim accrues at the time of the alleged breach, even where the injured party did not then know of the wrong.
Authority: Matter of Hersh, 198 AD3d 767, 769 (2d Dept 2021).
Accrual is not the end of it. Where the relationship continued, courts have held the clock does not run until the fiduciary openly repudiates or the relationship ends. Concealment can support equitable estoppel. Assume the plaintiff argues both.
Authority: Kaufman v Cohen, 307 AD2d 113 (1st Dept 2003).
So build the timeline before the merits. Put every transfer, amendment, and distribution the complaint describes on one page with dates. Compare that page to the commencement date.
Can the same facts support both a breach of contract claim and a breach of fiduciary duty claim?
Often they cannot. New York requires a fiduciary claim to rest on a duty independent of the contract. The Court of Appeals has framed it as a relationship of higher trust than would arise from the written agreement alone. Where every allegation traces to a promise in a signed document, the fiduciary count duplicates the contract count.
Authority: EBC I, Inc. v Goldman, Sachs & Co., 5 NY3d 11, 20 (2005); Clark-Fitzpatrick, Inc. v Long Is. R.R. Co., 70 NY2d 382, 389 (1987); William Kaufman Org. v Graham & James, 269 AD2d 171 (1st Dept 2000).
Run the test mechanically. Take each numbered paragraph of the fiduciary cause of action. Ask whether it describes conduct the operating agreement already governs. An allegation that you missed a required distribution is a contract allegation. So is one about withheld books and records.
Then compare the damages demands. The same sum, computed the same way, is one claim pleaded twice.
Know the limit. Where an independent fiduciary relationship exists, as between partners or a managing and non-managing member, duplication is not automatic. The count survives if it alleges disloyalty the agreement does not address and damages the contract measure does not capture.
The stakes are not academic. A duplicative fiduciary count exists to unlock remedies the contract does not offer: disgorgement, an accounting, and rarely punitive damages. Strike it and the case shrinks to what the parties signed.
A fiduciary claim that lives entirely inside a contract is not a second claim. It is the same claim wearing a better suit.
What can a motion to dismiss reach at this stage?
A motion to dismiss under CPLR 3211 can reach a breach of fiduciary duty claim on several grounds at the pleading stage, before any deposition. Statute of limitations is one, as the Court of Appeals confirmed in IDT. Failure to plead the circumstances in detail is another. So is documentary evidence that refutes the alleged relationship.
Documentary evidence is where a well-drafted deal pays for itself, within limits. Under CPLR 3211(a)(1) the proof must utterly refute the allegations and conclusively establish a defense. Unambiguous instruments qualify. Emails and affidavits generally do not. Useful documents include:
- The operating agreement, if it defines who manages and who does not.
- The partnership agreement, if it permitted the outside venture now called a usurpation.
- A written consent or waiver signed by the complaining member.
- Any release the plaintiff signed, if the conduct predates it.
Watch the clock on the motion itself. Most CPLR 3211(a) grounds must be raised before you answer, and some are waived otherwise. The motion is a menu, not a single dish. Choose grounds that dispose of whole counts.
What should you do next?
Your first task as a defendant in a New York breach of fiduciary duty case is not to explain yourself. It is to test whether the duty existed, whether the wrongdoing was pleaded in detail, when the conduct occurred, and whether the count merely repeats a contract claim. Do that before you answer.
Concrete steps:
- Collect the governing documents. The operating agreement, the partnership agreement, every amendment, every written consent.
- Mark your role in each. Manager or member, officer or shareholder. That often decides the first element.
- Build a dated timeline of every act alleged. Compare the earliest date to the commencement date.
- Highlight every allegation naming a specific transaction. If the highlighter stays dry, CPLR 3016(b) is your argument.
- Note the relief demanded. Money only usually means three years. Actual fraud, properly pleaded, buys six.
- Preserve everything now. Emails, texts, accounting files, bank records. Suspend automatic deletion.
- Stop discussing the dispute with the plaintiff, with employees, and in writing.
Then hand that package to counsel. A defense team such as Prencipe International can move far faster when the documents and timeline arrive together. The strongest motions are built from the plaintiff’s own complaint and the parties’ signed papers, and nothing else.
