Overview

Provided by Oberdier Ressmeyer LLP

Oberdier Ressmeyer LLP is a New York litigation boutique whose two partners prevail against opponents represented by the largest national and international firms. The firm takes lead-counsel roles in high-stakes commercial disputes from $15 million to over $1 billion, with a particular concentration in cross-border litigation and international arbitration. Both partners personally handle every matter, from strategy through trial and appeal.

The firm concentrates on complex commercial litigation, international arbitration, and cross-border disputes, frequently for Chinese, Hong Kong, Latin American, and European clients in U.S. courts and before the ICDR, HKIAC, and ICC. It has recently defeated a billion-dollar RICO claim, a nine-figure arbitration demand, a $63 million developer counterclaim in a major real estate dispute, and it serves as strategic counsel in two of the largest U.S. corporate criminal proceedings of recent years.
