O'Sullivan & Zacchea represents clients in the prosecution and defense of claims in commercial disputes and administration proceedings. Our clients benefit from a collaborative approach designed to ensure efficient, cost-effective representation to meet our clients goals. 

We provide expert counsel for civil litigation matters.

We commence and defend civil litigation matters involving real estate, business and partner disputes, contract disputes, complex commercial transactions, debt/financing issues, zoning issues, estate matters, administrative law and foreclosures. Our team has substantial trial experience before courts, administrative agencies and arbitration panels in New York, Queens, Brooklyn, Long Island and Westchester.

We work together with our clients from the inception of their case to create and present a winning argument at trial. We are cognizant of the cost of litigation - both time and money - and we are mindful of our clients' resources.

    Starting a business is a major event. Whether alone or in partnership, the proper formation is essential to the foundation of the entity. We counsel entrepreneurs, sole proprietors, start-ups, family businesses and small business through the critical process of formation. From understanding the value of incorporation and the various corporate forms to compliance with the rules and regulations of formation, our goal is to provide our clients with the proper platform for success. We regularly advise, draft and analyze operating agreements and partnership agreements, as well as joint ventures and acquisitions.
    Clear communication and mutual understanding is essential to business. Our clients rely on us to negotiate, draft and execute documents that accurately reflect their understanding, comply with regulations and achieve their goals. We counsel clients on reducing liability, mitigating risk and resolving problems before they arise.
    Commercial disputes can be complex and challenging. Businesses require skilled, experienced counsel to advise and advocate for them. We have counseled a wide variety of clients in commercial litigation, including real estate developers, accountants, attorneys and other entrepreneurs in connection with partnership disputes, corporate accountings, liquidations and dissolutions.
    As businesses expand and contract, legal needs often unexpectedly arise. We approach these transitions with our clients' unique financial and strategic plans in mind. We advise and counsel clients in connection with an array of commercial agreements including sales and supply agreements, research and development agreements, licenses, franchise agreements, distribution agreements and indemnifications. We also advise clients on establishing and implementing exit strategies for partners and owners, including transfer of ownership between partners, family members or chosen employees.
