Business Partner Stealing From the Company: What to Do in New York

A New York guide to spotting financial misconduct, avoiding the self-help trap, and getting your money back.

How to Tell If a Business Partner Is Stealing From the Company

Most partner theft does not look like someone walking out with cash. It looks like accounting that almost adds up. The early signs are quiet, and by the time the numbers feel wrong, money has usually been moving for a while. These are the patterns that surface most often before an owner realizes what is happening.

The financial reports you used to receive stop arriving, or show up late and incomplete.
The bank balance is consistently lower than your sales volume should produce.
Payments appear to vendors you do not recognize and cannot verify.
Your partner's draws or distributions no longer match the operating agreement.
Your partner resists an outside audit, a new accountant, or shared access to the books.
Expense categories spike with no business explanation behind them.
One partner has quietly taken sole control of the books, banking, and payroll.
Transfers appear at odd times or in round numbers that tie to no invoice.

Where the Money Actually Goes

Recognizing the symptoms is the first step. Understanding the mechanism is the second. Financial misconduct between partners almost always runs through one of six channels, and more than one often runs at the same time.

Ghost Vendors & Inflated Invoices

Payments flow to vendors that do not exist, are controlled by the partner or a relative, or are real vendors billing at inflated rates. The money leaves as a legitimate expense, and the partner keeps the spread.

Revenue Skimming

Cash or card payments that never reach the books. The diversion happens before the sale is recorded, which makes it invisible until you compare revenue against inventory depletion, supplier orders, or foot traffic.

Unauthorized Transfers & "Loans"

Money moved from the company account to a personal account, a related LLC, or a shell entity, often labeled a "loan" or "advance" that was never authorized and never repaid. In partnership disputes, these transfers become the centerpiece of the damages claim.

Personal Expenses Through the Business

Personal insurance, legal fees, home renovations disguised as office upgrades, and meals or travel with no business purpose, all run through the company card and buried in ordinary expense lines.

Diverted Business Opportunities

A client, contract, or project that belongs to the company gets routed through a separate entity the partner controls. This is breach of fiduciary duty in its purest form: taking not just money, but the relationships the business runs on.

Payroll & Compensation Manipulation

Unapproved raises, ghost employees, and bonuses paid to the partner or family. In closely held companies this is how theft scales quietly, compounding into real money that only a full accounting exposes.

Embezzlement, Theft, Fraud, Conversion: What's the Difference?

"Stealing" is the word owners use. The law uses narrower terms, and the label matters because it decides which claims you can bring and what you can recover. A partner with legitimate access who diverts money is rarely committing simple theft. Here is how the conduct actually breaks down in New York.

Embezzlement

Lawful possession turned to unlawful use. A partner who is entitled to handle company funds but redirects them to personal accounts is embezzling, even though no break-in or unauthorized access ever occurred. It is the most common form of partner theft precisely because access is built in.

Conversion

The civil counterpart to theft: exercising unauthorized control over money or property in a way that excludes the rightful owner. Conversion is what you sue on when a partner takes a specific, identifiable sum and treats it as their own.

Fraud

A knowing misrepresentation you relied on, that caused a loss. Fake invoices, fabricated vendor relationships, and false financial statements move the conduct from a bookkeeping dispute into business fraud territory, which can unlock punitive exposure.

Self-Dealing & Misappropriation

Using a position of trust to benefit personally at the company's expense: routing deals to a side entity, paying a related party above market, or taking a corporate opportunity. This is the core breach of the duty of loyalty every New York partner and member owes.

What Owners Get Wrong

When owners discover financial misconduct, the instinct is to act fast: change the passwords, freeze the accounts, lock the partner out, confront them, or move assets before they can. Every one of those moves can turn you from the victim into the defendant.

New York courts look at conduct on both sides. If you lock a partner out, transfer funds unilaterally, or take company property outside proper legal channels, the other side's attorney will use it against you in the shareholder and partnership dispute and may file a counterclaim that shifts the focus off what your partner actually did. The goal in the early weeks is not to retaliate. It is to build a clean, unassailable record while the other side keeps making mistakes.

What Not to Do, Ever

Do not confront your partner before preserving records. Do not move business assets unilaterally. Do not access systems or accounts you are not currently authorized to use. Do not send threatening messages. Do not tell employees, vendors, or clients what you suspect before speaking with an attorney. Every one of these actions weakens your position and hands the other side a narrative.

The 30-Day Playbook

Every day without action is a day your partner can move money, alter records, or build a counter-narrative. This is an illustrative sequence, not a court timetable. Urgent relief may need attention immediately rather than waiting for a later phase.

Civil and Criminal: Two Tracks That Run at Once

When a partner steals, two separate processes are available, and they do not depend on each other. Most owners care most about the civil track because it is where the money comes back. Lawful reporting serves a different purpose from civil recovery, and the prosecutor controls criminal charges.

The Civil Case
You control it
GoalRecover the money, remove or buy out the partner, or dissolve the business.
Who decidesYou and your attorney. You choose when to file, settle, or walk away.
ForumNew York Supreme Court, often the Commercial Division.
BurdenGenerally a preponderance of the evidence; common-law fraud requires clear and convincing proof.
The Criminal Case
The District Attorney controls it
GoalPunishment of the wrongdoer, not compensation to you. Restitution is possible but secondary.
Who decidesThe DA decides whether to charge. You cannot file or drop charges yourself.
ForumCriminal court, on referral from a complaint to the DA or police.
BurdenBeyond a reasonable doubt. A far higher bar than the civil case.

Parallel civil claims and a good-faith criminal report may be appropriate, depending on the evidence. New York lawyers may not pursue or threaten criminal charges solely for leverage in a civil dispute. Counsel should assess lawful reporting separately from settlement demands.

Seven Claims You Can Bring

Financial misconduct between partners supports multiple civil claims in New York, usually brought together. What each one accomplishes, and what it takes to prove, shapes how the case is built from the evidence up.

Breach of Fiduciary Duty
The foundational claim in most partner theft cases. Fiduciary duties depend on the entity, the owner's role and applicable law; corporate officers and directors, LLC managers and controlling owners may owe duties that do not apply identically to every passive investor. Taking company assets for personal use violates both. A successful claim supports recovery of the stolen amounts plus consequential damages to the business.
Conversion
A civil claim for the wrongful taking of property belonging to the business or to you. In New York, conversion requires showing ownership, wrongful dominion, and resulting damage. It can be brought alongside fiduciary duty claims and may support additional damages categories.
Fraud & Misrepresentation
Where the partner actively lied about how money was being used, about vendor relationships, or about the company's financial condition, a fraud claim may be available. Fraud requires proving intentional misrepresentation, reasonable reliance, and damages. It often overlaps with the fiduciary duty claim.
Breach of Contract
If the operating agreement or shareholder agreement prohibited the specific conduct at issue (unauthorized transfers, self-dealing, competing activity), a breach of contract claim runs in parallel. This matters for attorney's fees provisions and for cases where the fiduciary duty framework is disputed.
Unjust Enrichment
A fallback claim for situations where the partner benefited at the expense of the business or the other owners, even where a specific contractual provision does not cover the conduct precisely. Courts apply this where allowing retention of the benefit would be inequitable.
Derivative Action
Where the theft harmed the business entity (not just you personally), the proper vehicle is a derivative claim brought on behalf of the company. If successful, recovery goes back to the business. Choosing direct vs. derivative incorrectly can result in dismissal. It is one of the most common procedural errors in these cases.
Faithless Servant & BCL §720
Under New York's faithless servant doctrine, a disloyal fiduciary can be forced to forfeit all compensation earned during the period of disloyalty, on top of returning what was taken. Where the wrongdoer is a director or officer, BCL §720 provides a direct statutory route to compel an accounting and recover for misconduct and waste of corporate assets.

What You Can Actually Recover

The claim is only half the question. The other half is what each one puts back in your pocket. New York law offers more than a refund of the stolen amount, and the right combination of remedies often recovers more than the cash that left the account.

Compensatory Damages
The money taken, plus the downstream losses it caused: lost revenue, additional financing costs, and the value of opportunities diverted away from the business. This is the floor, not the ceiling.
Disgorgement & Constructive Trust
A faithless fiduciary does not get to keep the profit they made on your money. Courts can order disgorgement of those gains and impose a constructive trust over specific assets the partner bought with diverted funds, letting you reach the asset itself.
Faithless Servant Forfeiture
Under New York's faithless servant doctrine, a disloyal partner or employee can be ordered to forfeit all compensation earned during the period of disloyalty, on top of returning what was taken. Over a multi-year scheme, the forfeiture alone can exceed the theft.
Pre-Judgment Interest
CPLR 5004 generally sets interest at nine percent per year for ordinary commercial claims unless another rule applies. CPLR 5001 governs entitlement and the accrual date, including losses incurred at different times; in equitable actions, interest, rate and timing are discretionary. Counsel should calculate interest for the particular claims and losses.
Punitive Damages
Available where the conduct is egregious and morally culpable, not for an ordinary breach. Sustained fraud, fabricated records, and deliberate concealment are the fact patterns that support a punitive award when they are proven.
Attorney's Fees
New York follows the American Rule, so each side pays its own fees unless a statute, a fee-shifting clause in the operating or shareholder agreement, or a derivative recovery under BCL §626 changes that. Your governing documents are the first place to look.

Building the Case

These cases are won or lost on documents, not arguments. New York courts respond to patterns established through financial records, communications, and expert analysis. Suspicion without documentation is not a case.

Highest-Value Evidence Categories

Bank and financial records: Complete transaction histories showing unauthorized transfers, unusual timing, and amounts inconsistent with stated business purposes.

Vendor documentation: Contracts, invoices, and payment records for any vendor whose legitimacy is in question, particularly where the vendor is a related party or where services are vague.

Internal communications: Emails, texts, and messages referencing financial decisions, distributions, compensation changes, or business direction, especially anything the partner sent to themselves or to third parties that contradicts what they told you.

Accounting records: General ledger, payroll records, expense reports, and tax filings. Discrepancies between what was reported to the IRS and what actually moved through accounts are among the most powerful evidence available.

Forensic accounting analysis: For patterns that span years or involve complex structures, a forensic accountant traces the money through every layer. Their report becomes the damages calculation and the expert testimony that makes the numbers legible to a court.

Evidence gathering is not a passive exercise. In New York, it is an active legal process: books and records demands under BCL §624 or LLCL §1102, formal discovery once litigation is filed, and court-ordered accounting are tools that force production of records your partner controls and would rather you never see.

When You Need a Forensic Accountant

For a single unauthorized transfer with clean documentation, you may not need one. For anything that spans months or years, runs through ghost vendors, or involves skimming before the sale is recorded, a forensic accountant is essential. They trace the money through every layer, reconstruct what the books were hiding, and turn a stack of statements into a single defensible damages number. Their report becomes both the figure you sue for and the expert testimony that makes it credible to a court. The cost is real, but on a contested scheme it is usually the difference between a suspicion and a provable case.

Getting the Money Back After You Win

A judgment is a piece of paper until it is enforced. If your partner has spent or hidden the money, collection becomes its own phase, and New York gives a judgment creditor real tools to find assets and pull them back.

Restraining Notice (CPLR 5222)

Freezes the debtor's bank accounts and property the moment it is served, before they can move funds again. It is one of the fastest post-judgment levers and often the first one used.

Turnover Proceeding (CPLR 5225)

Compels the debtor, or a bank or third party holding their assets, to turn property over to satisfy the judgment. This is how you reach money that is sitting where you cannot grab it directly.

Information Subpoenas & Asset Tracing

Force disclosure of where the money and property actually are. Combined with forensic tracing, they follow funds through the personal accounts, shell entities, and relatives a partner used to move them out of reach.

Clawing Back Transfers

Money moved to family members or shell companies to dodge a judgment can be unwound as a fraudulent conveyance under New York's Debtor and Creditor Law, pulling those assets back into reach.
