About Osen LLC

Osen LLC is at the forefront of groundbreaking civil counter-terrorism litigation, battles to recover looted art and efforts to obtain property restitution for Nazi victims and victims of communist-era property confiscations. The matters we work on are specialized, complex and time-intensive. As a result, we only accept a limited number of matters to ensure that we provide our clients with access, responsiveness, and a high standard of professionalism.

 

Our firm has been described as having “a penchant for tackling larger-than-life cases” and being “on a mission to fight terrorists by cutting off their bankroll.” The New York Times has called our managing partner an “internationally consulted legal authority on terror financing,” and a federal court has noted our “unusual qualifications and experience to handle” complex cases.

 

We are intensely focused on creatively representing our clients around the world in ways that satisfactorily resolve their most important problems.
