When Living in Your Building Becomes a Fight

A Co-op Dispute Hits Close to Home

Unlike a typical apartment, your co-op is both your home and an investment tied to a proprietary lease and a board that holds real power. When a board denies your alteration, refuses your buyer, or comes after you over alleged arrears or house rules, the pressure is personal — and expensive.

Boards face the flip side: a shareholder who won't pay maintenance, ignores the rules, or disrupts the building puts every other resident at risk. Either way, co-op disputes turn on the proprietary lease, the bylaws, and how New York courts review a board's decisions.

Common Questions

Co-op Dispute FAQs

What is a co-op dispute?

A co-op dispute is a conflict involving a cooperative apartment building — typically between a shareholder (the resident-owner) and the co-op's board, or between the board and a shareholder. Common issues include maintenance and arrears, alteration and sublet approvals, house-rule enforcement, sale-application denials, and claims that a board acted unfairly or in bad faith.

Can I sue my co-op board?

In some situations, yes. However, New York courts generally give co-op boards significant deference under the business judgment rule, meaning a board's good-faith decisions within its authority are hard to overturn. Claims are more likely to succeed where a board acted in bad faith, outside the scope of its authority, or in a discriminatory or unequal way. An attorney can assess whether your situation fits one of those exceptions.

What is the business judgment rule in a co-op dispute?

The business judgment rule is the standard New York courts use to review co-op board decisions. As long as a board acts in good faith, within the scope of its authority, and in furtherance of the co-op's purposes, courts generally will not second-guess the decision. Understanding how this standard applies is often central to both challenging and defending a board's actions.

My co-op board denied my sale or alteration — what can I do?

Your options depend on the proprietary lease, the bylaws, and the reason for the denial. Boards have wide latitude, but that latitude is not unlimited — denials that are discriminatory or made in bad faith may be challengeable. Having an attorney review the governing documents and the circumstances is the best way to understand where you stand.

How much does a co-op dispute lawyer cost?

Fees depend on the nature and complexity of the dispute. We'll discuss fee structure directly with you so you understand the arrangement before moving forward. Contact our office to talk through your situation and the costs involved.
