Conversion Claims in New York: Recovering Stolen Money, Property, and Business Assets

Your bookkeeper just disappeared with $850,000 from your construction company's operating account. Your former partner emptied a joint Manhattan brokerage account and bought a beach house in the Hamptons. The bank tells you it's a civil matter, the police tell you to hire a lawyer, and the money is moving fast. In New York, the legal vehicle for getting that money back isn't a breach of contract claim — it's a tort claim called conversion, often paired with a constructive trust and an unjust enrichment count as alternative theories.

Conversion claims in New York are how businesses recover specific property and identifiable funds that someone has wrongfully taken or refused to return. They work in tandem with two equitable cousins — constructive trust and unjust enrichment — to plug gaps where a contract claim won't reach. Knowing when to use which theory, and how to lock down the assets before they vanish, is the difference between a meaningful recovery and a lawsuit against an empty shell.

What Is a Conversion Claim Under New York Law?

Conversion is the civil tort that mirrors theft. To win a conversion claim in New York, you must prove two things: that you had a possessory right or interest in specific property, and that the defendant exercised dominion or control over that property in a way that interfered with your rights. This two-element framework is well established under New York law and controls every conversion case filed in the state today.

The defendant doesn't have to consciously "steal" anything. Conversion is a strict-liability tort in the sense that good-faith mistake isn't a defense — if a vendor receives a wire transfer meant for someone else and refuses to return it after a demand, that's conversion. The classic ritual is a written demand for return followed by a refusal, which crystallizes the wrongful exercise of dominion.

The statute of limitations is short. Under CPLR § 214(3), you have three years from the date of conversion to file suit. That clock runs from the moment the wrongful taking occurred, not from when you discovered it — which is why the bookkeeper-skipped-town scenario can become a race against time if the theft happened years before the audit caught it.

Damages in conversion are typically the fair market value of the property at the time and place of conversion, plus interest. If the converted asset has fluctuated in value — say, converted shares of a startup that later spiked — New York courts can apply the highest intermediate value rule for certain securities. Most litigants miss that punitive damages are available in conversion when the conduct is willful and morally culpable, which gives the tort real teeth in cases involving fiduciary betrayal.

When Can You Recover Stolen Money Through a Conversion Action in NYC?

You can recover stolen money through a conversion claim in New York only when the funds are specifically identifiable and segregated, not when they represent a general debt. This is the single most-litigated issue in New York conversion law, and it trips up plaintiffs constantly. A breach of contract claim for $500,000 owed under an invoice is not a conversion claim, even if the defendant is acting like a thief — because the money is just an obligation, not a specific fund.

The line gets crossed when there's a particular, identifiable pool of money that the defendant was holding for your benefit or that belonged to you outright. Examples that satisfy the rule include funds wired into an escrow account, money sitting in a designated client trust account, insurance proceeds earmarked for a specific repair, and progress payments held under Lien Law Article 3-A trust fund obligations. In those cases, the money has a defined identity separate from the defendant's general assets.

That distinction matters tactically. A conversion claim opens the door to remedies that a contract claim doesn't — most importantly, prejudgment attachment under CPLR § 6201, which lets you freeze the defendant's assets at the outset of the case if you can show the defendant is disposing of property with intent to defraud creditors. We've covered the broader injunctive landscape in our piece on preliminary injunctions and TROs in New York, and attachment often runs in parallel with that relief.

NYC commercial scenarios where conversion of money typically applies include a managing partner who withdraws funds from a designated capital account for personal use, a contractor who diverts owner-paid trust funds to cover unrelated obligations, a brokerage account holder who liquidates jointly held positions without authorization, and a former employee who routes ACH payments from a customer-only payment processor into a personal account. In each, the money has a fingerprint that distinguishes it from a generic debt.

How Does a Constructive Trust Work in New York Business Disputes?

A constructive trust is an equitable remedy that treats the defendant as if they were holding property in trust for you, even though no formal trust was ever created. New York courts impose constructive trusts to prevent unjust enrichment when someone has acquired property through wrongful means or in breach of a confidential relationship. To establish a constructive trust, New York courts apply a four-factor test: a confidential or fiduciary relationship, a promise, a transfer in reliance on the promise, and resulting unjust enrichment.

The rules are applied flexibly. Courts have made clear the four factors are guideposts, not rigid elements, and constructive trusts have been imposed in cases where one factor is weak but the equities overwhelmingly favor the plaintiff. The remedy is powerful because it gives you ownership of the actual asset — not just a money judgment. If your business partner used embezzled funds to buy a Tribeca condo, a constructive trust lets you claim the condo itself, including any appreciation, instead of chasing a defendant who might be judgment-proof.

The statute of limitations for constructive trust claims is six years under CPLR § 213(1), the catchall provision for actions where no other limitation is specifically prescribed. The clock generally runs from the date of the wrongful act giving rise to the trust — though in cases of continuing fraud or fiduciary breach, accrual can be deferred. That six-year window is twice the conversion clock, which is why constructive trust is often the better vehicle when the underlying wrong happened years before discovery.

Constructive trust pairs especially well with claims arising in LLC and partnership disputes, where the confidential relationship element is essentially built in. A managing member who diverts a real-estate opportunity to a side LLC, a partner who buys out a third party using firm funds, a co-owner who titles a building solely in their own name — these are the bread-and-butter constructive trust scenarios in NYC commercial practice.

When Should You Plead Unjust Enrichment Instead of Breach of Contract?

You should plead unjust enrichment when there's no enforceable contract covering the dispute, or when you need an alternative theory in case the contract is held void or unenforceable. To state a claim, a plaintiff must show that the defendant was enriched, at the plaintiff's expense, and that equity and good conscience require restitution. It's a quasi-contract theory — the law implies an obligation to pay where fairness demands it, even without a signed agreement.

Unjust enrichment is not a catchall to be thrown into every complaint. If a valid contract governs the same subject matter, the contract claim displaces unjust enrichment. The doctrine fills gaps; it doesn't override agreements the parties actually made.

That said, unjust enrichment is indispensable in several NYC commercial scenarios. When a home-improvement contractor's contract is voided for failing to comply with GBL Article 36-A, the contractor's only path to recovery is unjust enrichment or quantum meruit for the reasonable value of the work. When a real-estate purchaser puts down a deposit on a deal that falls apart with no formal contract, unjust enrichment is the vehicle for recovering the deposit. When a business advances money to a vendor on a promise that's later disavowed, unjust enrichment captures the imbalance.

The statute of limitations is six years, also under CPLR § 213(1). Damages are measured by what the defendant gained, not what the plaintiff lost — a distinction that occasionally yields larger recoveries than a straight contract claim, particularly when the defendant resold property at a markup or used the plaintiff's funds to acquire something that has appreciated.

Experienced commercial litigators watch for cases where pleading unjust enrichment as an alternative is essential to surviving a motion to dismiss the contract claim — if the agreement turns out to have a fatal defect, the equitable count keeps the lawsuit alive.

What Procedural Steps Should You Take Immediately After Discovering Theft?

The first 30 days after discovering business theft determine whether you'll actually recover anything. Speed matters because converted assets get spent, hidden, or moved offshore, and a defendant who knows litigation is coming has every incentive to dissipate funds before a court can freeze them. New York courts will help you, but only if you move decisively.

The threshold steps look like this:

• Send a written preservation demand to the wrongdoer and any third parties holding identifiable funds (banks, brokerages, escrow agents) so the conversion clock and the demand-and-refusal element are documented.

• File suit and seek a TRO and preliminary injunction under CPLR § 6301 to freeze specific accounts and prevent transfer of identifiable property.

• Move for prejudgment attachment under CPLR § 6201 if you can show the defendant is a non-domiciliary, is concealing assets, or is acting with intent to defraud creditors.

• Subpoena bank records and trace the funds — most large conversions in NYC commercial cases involve a paper trail across multiple accounts and entities.

Pleading the case correctly is its own battle. Conversion and constructive trust claims that sound in fraud must satisfy the heightened pleading standard we walk through in our explainer on CPLR 3016(b) particularity. That means dates, dollar amounts, account numbers, and specific representations — not vague allegations of "misconduct."

If the wrongdoer ran the theft through a shell entity, you'll likely need to add an alter-ego count to reach the individuals behind the corporate veil. Our analysis on when New York courts pierce the corporate veil walks through the domination-plus-wrong test that controls those claims. Without alter-ego pleading, a judgment against an empty LLC is worth exactly what the LLC has in its bank account — which, by the time you get there, is usually zero.

Cases that meet the threshold are typically filed in the Commercial Division of the New York Supreme Court, which has dedicated rules and judges experienced in complex business disputes. The Commercial Division's docket includes a heavy concentration of conversion, constructive trust, and unjust enrichment claims, and the procedural rigor of that forum tends to favor well-prepared plaintiffs. Cases below the monetary threshold proceed in the regular Supreme Court track, which still has full equitable jurisdiction to grant injunctions and impose constructive trusts.

One last point on parallel proceedings: civil conversion lawsuits can run alongside criminal investigations, and a District Attorney's parallel prosecution often produces evidence — bank subpoenas, recorded interviews, forensic accounting — that strengthens the civil case. The Manhattan District Attorney's Office regularly handles white-collar matters involving stolen business funds, and a referral can be a useful pressure point even when criminal charges aren't ultimately filed. According to the NYC Comptroller's Office, the city itself processes thousands of claims each year that involve allegations of mishandled funds, giving you a sense of how frequently identifiable-fund disputes arise in commercial life.

Frequently Asked Questions

Can I sue for conversion if my business partner just won't pay me what I'm owed?

Probably not, at least not for conversion alone. Conversion requires identifiable property — a specific account, a specific check, a specific asset — not a general debt. If your partner simply owes you money under your operating agreement, that's a contract claim or a fiduciary-duty claim. Conversion enters the picture if your partner took funds out of a designated account or appropriated a particular asset that belongs to the business.

How long do I have to file a conversion claim in New York?

Three years from the date of the conversion under CPLR § 214(3). The clock runs from the wrongful taking, not from when you discovered it — which is why prompt forensic review matters so much. A constructive trust or unjust enrichment claim covering the same conduct typically has a six-year window, so even if the conversion clock has run, you may still have equitable remedies available.

What's the difference between conversion and fraud?

Fraud requires a misrepresentation, scienter (knowledge of falsity), and reliance. Conversion just requires a wrongful exercise of dominion over your property. You can have one without the other — a vendor who refuses to return a mistakenly-sent wire commits conversion but not fraud, while a fraudster who induces you to invest commits fraud but may not commit conversion if there's no specific identifiable fund. Many commercial cases plead both, because the same set of facts often supports each.

If I get a constructive trust, do I own the property outright?

Effectively, yes. A constructive trust gives you the right to have the property transferred to you, and the court can order the defendant to convey title. You take the asset with whatever appreciation has accrued — which is why constructive trust is so valuable when the wrongdoer used your money to buy a property that's gone up in value.

Conclusion

Conversion, constructive trust, and unjust enrichment are the three core equitable and tort theories New York businesses use to recover misappropriated assets when a contract claim alone won't do the job. Used together, they cover money, property, and improperly retained benefits across a wide range of NYC commercial disputes — and pairing them with attachment, injunctive relief, and alter-ego pleading is what turns a complaint into an actual recovery.
