What the relationship legally is
People call each other business partners whether they own a corporation together, share an LLC, or never formed an entity at all. The legal form decides which documents govern, what duties the owners owe each other, and which remedies are available. A handshake venture may or may not be a partnership in the legal sense, and that question can itself be the first issue in the case. In a corporation or LLC, the shareholders agreement or operating agreement usually controls exit and dispute resolution, and New York law treats corporations and LLCs differently when it comes to dissolution. Identifying the entity and its governing documents is the starting point for any strategy.
Urgent problems and early court relief
When one owner is diverting money, taking customers, or cutting the other off from information, waiting for a trial may not be workable. Courts can issue temporary restraining orders and preliminary injunctions in appropriate cases, and in some situations appoint a receiver or order an accounting, though these require a strong showing and are not granted routinely. Keep the records you already have lawful access to, such as bank statements and your own emails, and note evidence of any competing business. Ask a lawyer before copying company files to a personal account. Avoid retaliatory moves, like cutting off your partner's pay or changing the locks, until you have advice, since they can weaken your position.
How the litigation usually unfolds
After any emergency phase, a business partner dispute generally proceeds through pleadings, document exchange, depositions, and often a valuation contest if a buyout is on the table. Many cases end in a negotiated buyout or a structured separation once both sides have seen the records. An arbitration clause in the governing agreement can move the case out of court entirely. In our first meeting, we look at the entity documents, what has happened recently, which money or customers are at risk right now, and whether your goal is to stay, to leave, or to wind the business down. Those answers decide whether the first filing should be an emergency application or a more measured complaint.
