Corporate Litigation Over Company Ownership, Control and Assets

Business Divorce

50/50 Deadlock Judicial Dissolution Forced Buyouts Valuation Disputes Minority Oppression

Business divorce covers the separation of co-owners in a closely held New York business: negotiated buyouts, the sale of an interest or the entire company, and litigation when the other side refuses fair terms. We represent majority and minority owners of corporations, LLCs, and partnerships on the exit itself and on what surrounds it, including control of the company, access to its books and records, and the price of the departing stake.

Withheld Distributions Shareholder Agreement Breaches Derivative Actions Voting and Control Disputes Books and Records Demands

Shareholder disputes in a closely held New York corporation run from withheld distributions and blocked access to records through contests over voting power, board control, and the terms of the shareholders agreement itself.

Breach of Fiduciary Duty

Self-Dealing Diverted Business Opportunities Misappropriation of Company Funds Competing Business Ventures Fiduciary Accountings

A fiduciary claim arises when a partner, officer, director, or managing member uses a position of trust for personal benefit at the company’s expense, through self-dealing, diverted opportunities, or funds moved without authority. We pursue these claims for New York businesses and co-owners who uncover the misconduct, and we defend owners and managers accused of it, in damages actions, accountings, and disputes over removal from management.

Fraud & Tortious Interference Claims

Fraudulent Concealment Fraudulent Conveyance Claims Tortious Interference with Contract Conversion of Business Assets Aiding and Abetting Fraud

Business fraud claims reach conduct that contract law cannot: concealed liabilities, falsified records, assets conveyed out of reach, and third parties who induced a counterparty to walk away from its obligations. We represent New York businesses pursuing fraud, conversion, and interference claims against insiders, competitors, and counterparties, and we defend companies and owners accused of the same conduct in court and in arbitration.

Emergency Injunctions & TROs

Asset Freeze Orders Preliminary Injunctions Non-Compete Injunctions Prejudgment Attachment Business Lockout Relief

Applications for emergency relief in New York courts may be heard on an expedited schedule, and the record assembled before that hearing generally determines the outcome, because the responding side has little time to build one. A temporary restraining order can freeze an account, reverse a lockout, or halt a lease termination while the claim proceeds. We file applications for temporary restraining orders and preliminary injunctions, and oppose those obtained against New York businesses.

Lawsuits Over Contracts, Property and Debts

Contract Breach & Enforcement

Nonpayment Claims Deficient Performance Service Agreement Disputes Wrongful Termination of Contract Breach of Contract Defense

A counterparty that stops performing forces a decision with consequences of its own, because continued performance can waive the breach while premature termination can convert the non-breaching party into the defendant. We pursue payment and damages for New York businesses, and defend companies accused of breaching agreements they had cause to stop honoring, across vendor, service, supply and distribution relationships.

Real Estate & Lease Disputes

Holdover Proceedings Good Guy Guaranty Disputes Purchase & Sale Disputes Specific Performance Actions Yellowstone Injunctions

Commercial real estate disputes in New York run from lease defaults and terminations through fights over possession, guaranty liability, and deals that fail before closing. We represent landlords, tenants, buyers, and sellers on both sides of these matters: holdover and possession proceedings, injunctions that preserve a tenancy while a default is litigated, guaranty enforcement, and actions to compel or undo a sale of commercial property.

Construction Disputes

Mechanic’s Lien Claims Trust Fund Diversion Payment & Performance Bonds Construction Defect Claims Scope of Work Disputes

Construction contract disputes turn on whether the work performed matched the contract’s scope and where the project funds went. We represent owners, general contractors, subcontractors, and material suppliers on New York projects: filing and discharging mechanic’s liens, claiming against payment and performance bonds, litigating defective work and disputed scope, and tracing project funds a contractor spent somewhere other than the job they were paid to fund.

Misrepresentation & Fraudulent Inducement

Undisclosed Litigation Rescission Claims Merger Clause Defenses Negligent Misrepresentation Inflated Revenue Claims

A deal induced by false statements gives rise to claims the contract itself does not contain. We represent New York businesses that signed based on revenue figures, pending litigation, or financial obligations that were overstated, understated, or never disclosed at all, and we defend sellers and counterparties accused of making them, in actions seeking rescission, return of what was paid, and damages the merger clause does not bar.

Personal Guaranty & Business Debt Litigation

Personal Guaranty Enforcement Promissory Note Litigation Merchant Cash Advance Disputes Confessions of Judgment Business Loan Defaults

A personal guaranty converts company debt into the owner’s personal liability, which is why a business loan default frequently becomes a dispute about the guarantor rather than the borrower. Enforcement and defense turn on the scope of that guaranty, the validity of any confession of judgment supporting it, and whether an advance structured as a receivables purchase functions as a loan. We represent lenders enforcing a guaranty and the owners defending against one.

Judgment Enforcement & Asset Recovery

Restraining Notices Information Subpoenas Bank Account Restraints Judgment Domestication Property Liens & Executions

Collection is a separate proceeding from the case that produced the judgment. Recovery turns on locating assets, restraining bank accounts, compelling sworn disclosure of income sources, and docketing liens against real property the debtor owns. We enforce judgments against corporate and individual debtors, and domesticate those entered outside New York.

Tort Claims in Business Disputes Beyond Fraud and Contract

New York allows three years to bring each of these claims.

Interference With an Existing Contract

What New York requires

A valid contract with a third party, the defendant’s knowledge of it, intentional procurement of a breach without justification, an actual breach, and resulting damages.

Where the claim fails

The claim fails where the third party never breached or the defendant did not know of the contract.

Prospective Business Interference

What New York requires

A relationship that would have formed but for the defendant’s conduct, and wrongful means: conduct amounting to a crime or an independent tort, or conduct taken solely to cause harm.

Where the claim fails

Lawful competition for a customer, done to promote the defendant’s own business, does not qualify.

Unfair Competition by Misappropriation

What New York requires

Taking the results of a competitor’s skill, expenditures and labor, and using them to compete against the competitor’s own use of the same property.

Where the claim fails

The claim fails where nothing belonging to the plaintiff was taken and used against it.

Conversion of Property or Funds

What New York requires

A right to possess the property and an interference that defeats it. Money qualifies only as a specific, identifiable fund that must be returned or handled in a particular way.

Where the claim fails

Money owed under a contract, with no specific fund behind it, supports only a contract claim.

Deceptive Business Practices

What New York requires

Materially misleading conduct aimed at consumers at large that causes injury. Damages are actual loss or $50, up to three times actual loss capped at $1,000 if willful, plus fees the court may award.

Where the claim fails

Private contract disputes unique to the parties fall outside New York’s deceptive practices statute.

First Steps When a Business Dispute Becomes a Lawsuit

Deadline to Answer a Lawsuit

A company served by personal delivery to an officer, member, manager or authorized agent has 20 days to respond. A company served through the Secretary of State has 30 days from the date service is complete, and that date comes before the company receives anything: the papers are forwarded afterward to the mailing or email address on file with the Department of State, so an outdated address can use up the full 30 days.

Vacating a Default Judgment

A company that misses the deadline is in default, and the plaintiff can ask for judgment on the complaint without any defense being heard. Before judgment, the court can extend the time or accept a late answer on a reasonable excuse. After judgment, a motion to vacate for excusable default is due within one year after service of the judgment with notice of entry and must show a reasonable excuse and a potentially meritorious defense.

Evidence Both Sides Must Preserve

The duty to preserve evidence begins once a party is on notice of a credible probability of litigation, which can be well before any suit is filed. From then on, routine deletion of email, text messages and files has to stop. If relevant evidence is destroyed after that point, a court can let the factfinder infer it would have hurt the party that destroyed it, bar that party’s proof, or, for willful destruction, strike that party’s pleading.

Notice and Cure Before Termination

Where a contract requires written notice and a chance to cure before termination, New York courts enforce the requirement strictly, and a termination without that notice is ineffective. The notice is excused in narrow situations, such as repudiation, abandonment of performance, or a breach that cannot be cured. The same clause can bar a company from fixing the other side’s work and deducting the cost without first giving notice.

Counterclaims in the Answer

The answer is where a company asserts its own claims against the plaintiff, and New York allows any claim a defendant holds against the plaintiff to be raised as a counterclaim, related or not. A counterclaim that was timely when the complaint was filed stays timely, and one arising from the same transaction can be asserted up to the amount the complaint demands even if it would otherwise be time-barred.

Settlement Talks as Evidence

Settlement offers, and statements made during settlement negotiations, cannot be used to prove liability or the amount of a claim. The protection has limits. Documents and facts that are discoverable on their own do not become protected by being discussed in negotiations, and statements from the talks can still be admitted for another purpose, such as showing a witness’s bias or answering a claim of undue delay.

Where a New York Business Case Gets Decided

Thresholds and Case Types in the Commercial Division

The Commercial Division is the part of New York Supreme Court reserved for business disputes, and its monetary threshold is set by county: $500,000 in New York County, $150,000 in Kings County, $100,000 in Queens County and $75,000 in Bronx County. The figure counts compensatory damages only, without punitive damages, interest or fees, and since March 2025 an action seeking only equitable relief must clear it too, measured by the value of what the suit protects.

The claim must also fall within the listed commercial categories, such as breach of contract or fiduciary duty, business fraud and the internal affairs of business organizations. Shareholder derivative actions and dissolution proceedings qualify regardless of amount, while suits to collect professional fees, lease disputes over rent alone and proceedings to enforce a judgment are excluded.

Arbitration Clauses in Business Contracts

New York courts enforce arbitration clauses in commercial contracts and stay a lawsuit filed in the face of one. Disputes over these clauses turn on scope: a clause covering disputes arising under an agreement reaches less than one covering disputes relating to it, so a fraud or fiduciary claim can stay in court while the contract claim goes to arbitration.

Under the American Arbitration Association’s commercial rules, an emergency arbitrator can act before the panel is formed in arbitrations under agreements made on or after October 1, 2013, unless the parties agreed otherwise, and asking a court for interim relief does not waive arbitration. Review of an award is narrow: a court can vacate it only on the statutory grounds, such as corruption, fraud or misconduct in procuring it, an arbitrator’s partiality, or an arbitrator exceeding its power.

State Court and Federal Court Jurisdiction

A dispute between New York companies reaches federal court only through a federal claim, because diversity jurisdiction requires that no plaintiff share a state of citizenship with any defendant and that more than $75,000 be in controversy. A corporation is a citizen of its state of incorporation and of the state of its principal place of business.

Federal cases from Brooklyn, Queens and Staten Island go to the Eastern District, and those from Manhattan and the Bronx to the Southern District. Federal rules require each side to disclose its witnesses, documents, damages computation and insurance without a request, and a federal civil verdict must be unanimous unless the parties agree otherwise, while a New York State jury of six can decide by five. A state court defendant whose case qualifies for federal court has 30 days from receiving the complaint to remove it.

County Venue Rules for a Business Lawsuit

Venue lies in a county where any party resided when the action began, or where a substantial part of the events giving rise to the claim occurred. A contract that fixes venue in advance is enforceable on motion, so where the agreement names a county, that choice controls.

A corporation resides in the county of its principal office, so a company with a warehouse in Queens and its principal office in Manhattan can be sued in Manhattan. A partnership or individually owned business resides both where its principal office is and where the partner or owner suing or being sued lives. A defendant sued in an improper county serves a written demand naming a proper one with or before its answer, and if the plaintiff does not consent within five days, the defendant can move to transfer the case within fifteen days after serving the demand.

Disputes That Cross State Lines

Parties and Claims Outside New York

Jurisdiction Over an Out-of-State Company

New York courts can hear a claim against an out-of-state company that arises from its business here or a contract to supply goods or services here, a wrong other than defamation committed in the state, or real property it holds here. Service outside New York follows the in-state rules.

Claims That Arose in Another State

A claim that arose outside New York must be timely under both New York’s limitation period and the period of the place where it arose, so the shorter of the two controls. A claim that arose in favor of a New York resident is measured by New York’s period alone.

Subpoenas From Cases in Other States

To reach a New York business, a subpoena from another state’s case is presented to the county clerk where the discovery is sought, or to a New York attorney, who issues a New York subpoena on the same terms. A motion to quash or modify it is made in the court of that county.

Interstate Contracts and Judgments

Choice of New York Law

In a transaction of $250,000 or more, the parties can choose New York law even where the contract has no other connection to New York. The rule does not reach contracts for labor or personal services, or for personal, family or household services.

Consent to New York Courts

Where a transaction of $1 million or more chooses New York law and the out-of-state party agrees to New York’s courts, a suit against that party can be brought here, and a New York court cannot dismiss or stay it on the ground that New York is an inconvenient forum.

Out-of-State Judgments

A judgment from another state can be filed with a county clerk within 90 days of its authentication and then works as a New York Supreme Court judgment. A judgment entered by default in appearance or by confession is excluded and is enforced through an action on the judgment instead.

Court Orders That Secure Assets and Recover Property

Provisional Remedies Before Judgment

Order of Attachment

In an action for money, a court can freeze a defendant’s property where the defendant lives out of state, is a foreign company not qualified to do business here, or has hidden or moved property to defeat a judgment. The plaintiff posts an undertaking covering the defendant’s losses if the attachment proves unwarranted.

Temporary Receiver

A court can appoint a receiver to take charge of property that is the subject of the lawsuit where there is danger the property will be removed from the state, lost, materially injured or destroyed. The appointment can come at any point before judgment and while an appeal is pending, on the motion of an interested party.

Lis Pendens Filing

Where the judgment sought would affect title to, or the possession or use of, real property, a notice of pendency filed with the county clerk binds later buyers and lenders to the outcome of the case. The notice lasts three years from filing, and the court can extend it for good cause by an order entered before it expires.

Remedies That Return Property and Money

Voidable Transfers

A transfer made to hinder, delay or defraud a creditor, or made for less than reasonably equivalent value by a debtor left with too few assets to pay its debts, can be undone to the extent of the creditor’s claim. A claim of intent to defraud runs four years from the transfer, or one year from when it could reasonably have been discovered, if later.

Accounting From a Fiduciary

Where a managing partner, officer or managing member controls the money, New York courts can order a full accounting of how it was handled, provided the claimant has no adequate remedy at law. The right extends to a nonmanaging member against the members who manage the company.

Constructive Trust

A court can declare that property held by one party belongs in equity to another where there was a confidential or fiduciary relationship, a promise, a transfer in reliance on it, and unjust enrichment. The holder need not have acted wrongfully; the question is whether it can keep the property in good conscience.
