Where others see a wall, we find a way.
Powerful advocacy built on strength, creativity, and global reach.
The Firm
Advocacy without borders.
Clients come to Seiden Law when the path isn't straightforward, the defendant is hard to reach, and another firm has called the case too risky or not worth the fight. When issues are not black and white and unique problems call for creative solutions, we set ourselves apart.
We take on the biggest commercial disputes, international and domestic arbitrations, judgment enforcement proceedings, and economic sanctions matters for multinational companies, sovereign governments, high net worth individuals, and defrauded investors and creditors.
Our matters cross the world but what sets us apart is not only our global reach but what we do with it. We pursue countries that other firms treat as untouchable, using tools most of the profession overlooks and pressing forward where others stop.
