Osen LLC is a boutique law firm with offices in mid-town Manhattan and Hackensack, New Jersey. We litigate high-profile and complex international cases bringing us into conflict with some of the world’s most powerful governments and corporations. We often litigate against some of the country’s most prominent law firms, but we retain an old-fashioned commitment to personal client service. We work in concert with other talented law firms around the globe, thereby allowing us to tackle major cases while avoiding conflicts and maintaining the flexibility of a small firm.
Our attorneys understand how difficult it is for individuals to obtain justice in a world dominated by impersonal, self-serving governments and large corporate conglomerates. We work hard to deliver high-quality legal services that fit within our clients’ budgetary guidelines. We understand that the playing field isn't level and know what it takes to deliver positive results: single-minded dedication, creative thinking, innovative strategy and the will to take on powerful interests without deference or hesitation.
Many law firms understandably tout their well-known institutional corporate clients, but we are equally proud of the hard-working and decent people we represent. They are often people that the legal system has failed and history threatens to forget. Their stories are our life-blood, and their cases are our cause.
The global scope of our practice requires us to help protect our clients’ interests in a variety of domestic and foreign jurisdictions. Whenever the circumstances dictate, our clients can count on capable legal representation in almost any forum and almost any language. Our cases range from terror financing litigation to stolen art cases to complex German property restitution, and because our practice is wide-ranging, our attorneys have been quoted or featured in many leading newspapers and magazines in the United States and around the world, including The New York Times, The Wall Street Journal, The Washington Post, The BBC, CNN and numerous other publications and forums.
