Litigating for Long Island businesses
Supreme, District & Surrogate's Court coverage in Nassau and Suffolk
High Stakes, Handled Directly
Commercial litigation is where business disputes get decided: contract breaches, partnership disagreements, and vendor conflicts that threaten what you've built. Before founding the firm in 2006, Shari spent years at multi-practice Long Island firms handling commercial litigation and asset protection, and that experience shapes how every dispute gets handled as part of our business law practice.
Many of the disputes we see start the same way: a deal done on a handshake, an operating agreement nobody updated, a partner who never signed anything. If that's you, you're not alone, and the worst move is waiting to see if it blows over.
Our approach is straightforward. When a dispute can be resolved through negotiation, we pursue that path first, because the fastest good outcome is usually the best one for the business. When it can't, we're fully prepared to represent you in court, and we appear in Nassau and Suffolk County Supreme Court so regularly that other law firms hire us to cover their appearances.
You also won't get lost in the shuffle. Unlike larger firms, you work directly with the attorney who understands your business and knows your file, at every stage, from the first demand letter to the last signature on a settlement.

What a Commercial Lawsuit Actually Looks Like
Most owners have never been through one. Click each stage to see what happens and where cases usually end.
Demand & Negotiation
A demand letter lays out your claim and what resolves it. A meaningful share of disputes end here, because a letter from a litigation attorney signals you're prepared to go further.
Filing the Lawsuit
If talks fail, a summons and complaint gets filed and served. If you're on the receiving end, the response clock is already running: generally 20 to 30 days in New York depending on how you were served.
Discovery
Both sides exchange documents, answer written questions, and sit for depositions. This is usually the longest stage, and it's where cases are won by the side with better records.
Motions
Either side can ask the court to narrow the case or end it outright. A strong motion can resolve a dispute without ever picking a jury.
Settlement or Mediation
Most commercial cases resolve here, on terms shaped by everything that came before. Preparing like you'll try the case is what gets you good terms at this table.
Trial
If no resolution comes, the case is decided in court. By this point you'll know your case inside and out, because we will have built it that way from day one.
Timelines vary: some disputes resolve in months, complex cases can run years. We push for the earliest resolution that actually protects your business.
Personal Attention. Aggressive Advocacy.
Business owners turn to us because they get both. We listen, explain your options in plain English, and keep you informed at every stage, and then we fight for the outcome. The same values that run the whole firm run the litigation practice: integrity, honest open communication, and hard work.
Litigation is also where prevention pays for itself. Nearly every partnership dispute we handle traces back to an agreement that was never drafted or never updated. If your dispute settles and you want to make sure there's never a second one, our business contracts work closes those gaps for good.
And if the fight is over who takes the company forward, the long-term answer usually isn't another lawsuit. It's a succession plan that settles the question in writing.
