Business Litigation Lawyer Long Island
The Frank Law Firm provided me with legal advice and guidance during a difficult situation. I came to them to review and explain a legal contract I had signed. Amanda was very knowledgeable and explained the document thoroughly. She was very reassuring, and honest in answering all my questions. I would highly recommend to anyone seeking legal representation to reach out to this firm.
Thomas Frank came highly recommended by an attorney I trust and represented me in a complex matter against a large business entity represented by a large NYC firm. He immediately grasped the nature and scope of my case and came up with a brilliant, linear strategy in short order. Just as swiftly, Thomas strategically executed on each step. I have worked with white glove law firms and have never found the level of consistency and professionalism that Thomas provided in his capacity of counsel. He literally made zero mistakes, even in the moments of game time decisions in the courtroom. Not only that, his creativity and judgement led to an outcome that exceeded my expectations, and, as a human being, he was an absolute pleasure to work with. I cannot recommend Thomas Frank highly enough!
We came to Frank Law Firm because our original attorney put us in a scenario where everything was mismanaged. Amanda quickly cleaned up our previous attorneys mess and put us back on track. From day one they were very transparent about their process and fees. They provided fantastic guidance for us as new home owners. The team was highly responsive and often took time to ensure we fully understood potential outcomes and next steps. Overall we would work with them again and recommend to friends.
Amanda was a pleasure to work with!!! Selling and buying a home at the same time is very stressful too begin with and my experience was very difficult and stressful to say the least. Amanda was so patient, always available, and very knowledgeable to every question and concern that I had. I was truly blessed to have her represent me with both of my transactions. I would definitely recommend The Frank Law Firm to anyone that is looking for the best lawyers out there!!!
Amanda was extremely attentive and followed up on everything promptly. The law firm was professional and courteous and I highly recommend it.
Top of the line customer service. Helped me get my moving violation dismissed and I didn't have to do anything ! Was certain I would get in some trouble but was completely shocked when I received the news that it was completely dismissed. In the past with other law firms I paid a lot of money to only get the penalty months later. The Frank Law Firm dealt with my situation in the most kind and professional way. Very nice people.

Thomas Frank was a pleasure to work with. The experience was nothing but a professional one. Mr. Frank guided me through the whole process of Chapter 7 bankruptcy. He was always available to reach by email or texting at any time that I contacted him. He never failed to get back to me within hours. I highly recommend Mr. Frank for all of your legal issues. Also, you'll find their price for their legal services to be more than fair. Again, a great big thank you to a professional and knowledgeable team.
I needed an attorney quick fast and in a hurry. My girlfriend recommended this firm. I called and Amanda got back to me quickly. She researched my issue and gave me good guidance. She is a former prosecutor but able to explain convoluted legal concepts in a very straight forward way. We didn't wind up retaining the firm due to the time contraints of our case, but I know we will be working with them in the future. Give them a call, I think you will like what you hear.
I would like to thank Thomas in handling my first time home buying experience with his law firm. He was very polite and very professional. He even took the time to explain to me page by page about some documents I received from the seller, which by the way it was on his spare time to answer all of my concerns about those documents. He responded on every email and text that I had questions and concerns and I got answers. Thomas made himself accessible and told me if I have any other closing related issues pertaining any documents to give him a call. Thank you once again on doing a great job. I would highly recommend Thomas Frank and his law firm.
I retained Frank Law Firm when I received a warrant for an unpaid ticket. Not knowing the severity of this issue, I called and consulted Amanda. Before giving me any direction, she took the time to make some calls and figure out what exactly was going on. She then guided me through the process. She was very comforting and explained everything in a manor that I understood. I would like to send a sincere thank you to her and Frank Law Firm. The amount of attention and guidance I received was refreshing. I would recommend them to anyone!
The Frank Law firm has helped me and my family tremendously. Amanda has been nothing but a blessing with her vast knowledge and resources, Me and My family were very satisfied with their service. Would definitely recommended them.
I'm a real estate investor in NY and I honestly could not ask to partner up with any firm better than the incredible people at Frank Law Firm. There passion, love and dedication for what they do is evident. I can't thank them enough for everything they have helped me with so far and we are only going to grow from here...

Commercial Dispute Attorney Long Island
The Commercial Division is a specialized part of New York Supreme Court for bigger business disputes, and getting in depends partly on the dollar amount. In Nassau County, the threshold is $200,000. In Suffolk County, it's $100,000. That means a $150,000 dispute could qualify in Suffolk and not in Nassau.
Those figures leave out punitive damages, interest, costs, and counsel fees, and some corporate-governance cases are exempt. The thresholds are set by court rule and can change, so we confirm the current numbers for your case. As a commercial dispute attorney on Long Island, we'd rather you know where you're headed before anything is filed.

Commercial Trial Attorney Long Island
Small businesses make up about 90 percent of registered companies on Long Island, and plenty of them operate out of leased or mortgaged property. So the disputes we see often involve a lease, a loan, or a piece of real estate. Our practice also covers foreclosure, lis pendens, easements, SBA lending, and loan modifications, and we've represented creditors, debtors, and trustees.
If you need a commercial trial attorney on Long Island, you get lawyers who understand both sides of the table and can try your case if negotiating stops working. We only escalate when it serves your business.

Have a question about your situation? Start with a conversation.
Ask our team ↗Most commercial litigators in New York bill hourly, and we do too. What you'll pay depends on the scope of the dispute, how hard the other side pushes back, and how many stages it goes through: demand letter, pleadings, discovery, mediation, and possibly trial. We won't throw out a number before we've seen your documents. What we will do is explain how billing works at the start, break the likely path into stages, and tell you honestly when a stage may not be worth the spend. Be careful about choosing any Long Island commercial litigation attorney on the lowest hourly rate alone. Ask for the plan, then compare. You can request a free quote on this page.
The Commercial Division is a specialized part of New York Supreme Court for larger business disputes. To qualify, your case has to be the right type, such as breach of contract, fiduciary duty, shareholder or partnership disputes, or commercial real property transactions, and it has to clear a dollar threshold set by county. In Nassau County that's $200,000. In Suffolk County it's $100,000. Interest, costs, and counsel fees don't count toward it, and some corporate-governance cases are exempt. Because the thresholds are set by court rule and can change, we confirm the current figure for your case before anything is filed.
As soon as you have the papers, or sooner. A summons carries a deadline to respond, and missing it can seriously hurt your position, so don't set it aside hoping it resolves on its own. Call us before you answer, before you send a demand, and before you sign any settlement. In the meantime, keep every email, text, invoice, and contract, and don't delete anything, even if it looks unhelpful. A business lawsuit lawyer on Long Island can often spot a defense, a counterclaim, or a contract clause that changes your position in the first conversation. Waiting rarely improves anything.
There's no honest single answer, because it depends on the facts, the other side, and the court. Some disputes settle after a demand letter or a motion. Others go through discovery and mediation, and a smaller number reach trial. Court calendars matter too, and in Suffolk County a case can stretch for months if nobody keeps it moving. We plan for both settlement and trial from day one, so you're never negotiating from a weak position. No lawyer can promise an outcome, and we won't. What we can do is tell you where your case likely sits.
Not always, but it helps more often than you'd think. Many Long Island businesses buy from Manhattan or New Jersey suppliers, sell to customers in Florida, or have owners who split time between states. Contracts often name where a dispute must be heard, and that clause can pull you out of Nassau or Suffolk entirely. We're licensed in New York, New Jersey, Florida, and federal courts, so a cross-border dispute doesn't mean hiring a second firm and re-explaining everything. If your contract has a venue or forum-selection clause, bring it to us first.
Bring whatever shows the story: the contract or lease, invoices, emails and texts, any demand letter or summons, corporate documents like an operating or shareholder agreement, and a rough timeline of what happened and when. Don't worry if it's messy or incomplete. We'd rather see everything than a polished summary. On the first call, we'll ask what outcome you want, what's at stake for your cash flow, and whether you'd like to preserve the relationship. Then one of our attorneys, not an intake coordinator, will tell you where you stand and what your options look like. Call 516-246-5577 and we'll take it from there.
