Where Advocacy Meets Business

“He is fully dedicated to the case and the client. He instils confidence that every aspect of the case is being meticulously and personally attended to.”

-Chambers USA

Andy Frischknecht excels at resolving difficult cross-border disputes. In over 20 years of practice, he has handled litigation and arbitration involving parties, evidence and laws on every continent.

Eine Kurz-Biographie auf Deutsch finden Sie hier.


Andy is known for leveraging jurisdictional and other procedural defenses to shut down cases early, saving overseas clients the time, expense and uncertainty of litigating in an unfamiliar system. When cases do continue, he has the experience to see them through to conclusion. He has dealt extensively with recurring issues in cross-border disputes such as foreign sovereign immunity, data privacy, and discovery in aid of foreign proceedings under 28 U.S.C. § 1782.

Andy has acted as counsel in international commercial arbitrations under various institutional rules (including the ICC, ICDR, SIAC, NAI and Swiss Rules). He is a recognized award and judgment enforcement specialist and, for over a decade, has led or co-led nearly all of the firm’s major engagements in this area. Andy co-authored the leading treatise on the enforcement of foreign arbitral awards and judgments in New York and has opined as an expert in foreign proceedings on U.S. award enforcement issues.

Andy is an officer of the International Bar Association’s Litigation Committee and co-editor of its Newsletter. Originally trained as a Swiss lawyer, he has a deep understanding of both the common and civil law systems and traditions. He is a sympathetic and effective guide for businesses and individuals confronted with U.S. disputes. And as a bilingual German speaker, Andy regularly represents German-speaking clients in litigation and arbitration proceedings.

Andy has been with Chaffetz Lindsey since the Firm’s founding in May 2009. Previously, he was associated with Clifford Chance US LLP and Hughes, Hubbard & Reed LLP.
