Co-Ownership Litigation in Business and Real Estate: Partition, Derivative Claims, and Dissolution Strategy

 When co-owners start fighting, the instinct is to “file something.”

That is usually the first mistake.

In ownership disputes involving businesses or real estate, the most important decision is not whether to sue. It is what procedural vehicle you choose. Partition. Derivative action. Direct fiduciary claims. Dissolution. Receivership. Each one changes leverage, remedies, timing, and valuation risk. If you choose wrong at the start, you spend the rest of the case trying to recover.

The partition trap

Two siblings inherit a mixed-use building. One wants to sell. The other wants to keep collecting rent. The knee-jerk reaction is a partition action. But the real question is simple: who owns the property?

• If title is held personally by the co-owners, partition may be correct.
• If an entity owns the property, partition is usually wrong. The dispute is about governance and control.

If the property qualifies as heirs property under RPAPL 993, statutory procedures can alter settlement posture, valuation mechanics, and timing. That analysis belongs at the beginning of the case, not after filing.

Partition disputes frequently overlap with broader business disputes and commercial litigation where ownership structure determines the remedy.

Direct vs. derivative: who was harmed?

In a 50/50 LLC, one member diverts company funds to a related entity. The first legal question is not how offensive the conduct feels. It is: who suffered the injury?

If the entity was harmed, the claim is derivative. If the owner suffered a distinct personal injury, the claim may be direct. Plead this incorrectly and you can lose standing before you ever reach the merits.

Derivative actions for breach of fiduciary duty, self-dealing, and misappropriation are common in ownership disputes. (For more on that, see our work on Derivative Actions and Fiduciary Litigation.)

Common lawsuits in co-ownership conflicts:

• Derivative actions for breach of fiduciary duty or waste
• Direct oppression or freeze-out claims
• Judicial dissolution petitions
• Partition actions involving co-owned real estate
• Books-and-records proceedings used as leverage in buyout disputes
• Emergency applications tied to asset diversion or deadlock

The receiver fantasy

Clients often ask for a receiver immediately. Courts do not grant receivers lightly. Receivership is extraordinary relief. Disagreement is not enough. Allegations are not enough. You need proof that property or business assets are at risk of being lost or materially injured.

Asking for a receiver without sufficient factual support can reduce credibility and weaken leverage in ongoing commercial litigation.

Dissolution is not always leverage

Lawyers often threaten dissolution early in a dispute. Sometimes it works. Sometimes it destroys enterprise value. If the business depends on vendor relationships, licensing, financing, or regulatory approval, public dissolution litigation can trigger cascading harm.

A strong complaint is not always a smart complaint. Litigation strategy must account for operational fragility.

Ethical landmines

Representing the entity versus representing an individual stakeholder is not a minor distinction. Blurring those roles creates conflict exposure and unnecessary motion practice. Ethical clarity is strategic clarity.

The real issue: leverage architecture

Ownership litigation is about designing leverage. The procedural vehicle controls standing, remedies, buyout dynamics, valuation exposure, and pace. The first filing often determines the trajectory of the case.

NYS' Deceptive Acts and Practices Law Expanded and the AG will be Coming for Business

NYS' Deceptive Acts and Practices Law has been expanded to include "Unfair, Deceptive, or Abusive Acts and Practices" and it is now called the FAIR Act - "fostering affordability and integrity through reasonable (FAIR) business practices act" - with the changes being effective on February 17, 2026. The biggest change being that the law's, GBL 349, consumer-oriented requirement has been dropped as a requisite for the Attorney General to bring a claim, but not for private claims. Under the amended law, a business' act is now also violated for being "unfair" and "abusive." 

Unfair means that the act "causes or is likely to cause substantial injury which is not reasonably avoidable and is not outweighed by countervailing benefits to consumers or to competition." 

Abusive means if: 

"(i) "it materially interferes with the ability of a person to understand a term or condition of a product or service; or

(ii) it takes unreasonable advantage of:

(A) a lack of understanding on the part of a person of the material risk, costs, or conditions of a product or service;

(B) the inability of a person to protect such person's interests in selecting or using a product or service; or

(C) the reasonable reliance by a person on a person engaging in the act or practice to act in the relying person's interests." 

Businesses hit with claims under this amended law, remember YOU HAVE FIVE BUSINESS DAYS after receipt of a certified mail from the attorney general to advise as to why an action or proceeding should not be instituted. 

If you receive a certified letter from the NY Attorney General under the FAIR Act, you have five business days. Call Lieb at Law immediately.

FTC Drops Non-Compete Ban: What Employers and Employees Need to Know About Enforceability

On September 5, 2025, the Federal Trade Commission gave up on its federal non-compete ban. As a result, employees who are subject to non-competes can no longer expect a white night, in the form of the FTC, to free them from their handcuffs when seeking to jump jobs. Instead, non-competes will once again need to be evaluated on a case-by-case basis for enforceability by counsel prior to an employee considering their options and a new employer considering hiring while being subject to a tortious interference with a contract claim. Otherwise, questions like the non-compete's duration, scope of activities, and geographic restrictions will be before the courts. Judges will need to determine if an employee had specialized training or investment from the employer, whether the non-compete concerns a job function dealing with trade secrets and conditional information, and how goodwill was utilized in forming the customer relationship. Then, there is the issue of the enforceability of liquidated damages clauses (predetermined damages for breach) and whether the court will fully strike an overly broad non-compete or instead blue pencil it into a more modified non-compete. Either way, employers who cannot gamble as to what a judge will do and face deep-pocket competitors, who will happily battle out poaching a start employee, should consider garden leave where the employee remains on payroll for the period of the non-compete to avoid ever having to earn a living otherwise while preserving loyalty for as long as the employer seeks. 

Facing a Non-Compete Issue?
