Trial Ready and Broad Record of Success

In today’s risk-averse legal environment, there are few firms that can match Weil’s trial resume and breadth of practice. Drawing on the robust experience of leading trial lawyers across all of our practices and offices, our litigation attorneys possess the tools to take any matter to trial – and win.

Notable Representations, Key Contacts

Success at Trial. While our litigation group is well-versed in all aspects and phases of the litigation process in jurisdictions around the world, we have  particularly robust experience  taking our clients’ most important matters to trial – and we have a superior record of success.

  • Weil’s Litigation Department counts more than two dozen, first-chair trial lawyers who regularly coordinate and try complex cases. We seek to engender in all of our litigation attorneys a trial-ready posture at the outset of every matter.
  • Weil is regularly called upon to manage and try unique cases that involve emerging technology, bet-the-company levels of damages, and/or issues of first impression.
  • Though we typically handle the majority of our trial work in the course of an existing representation, we occasionally are called in by other firms, and their clients, to assist with or lead trial proceedings just before they commence.
  • We excel at navigating our clients through multijurisdictional, multi-phase matters that involve a range of practices and specializations.

An Efficient Approach. We recognize that each case affords the opportunity to win prior to trial. Clients hire us because we have the ability to identify the weaknesses in our adversary’s case quickly and the broad knowledge to take advantage of those weaknesses and to emphasize the strengths of our clients’ cases. Our goals are always to assist our clients in managing risk, capitalizing on strategic opportunities, and obtaining the best results in litigation.

Weil litigation partners are consistently trying cases before judges, juries or arbitration panels in venues around the world, and our extraordinary efforts have resulted in substantial, game-changing outcomes for our clients. In the last two years alone, more than 26 litigation partners have tried and won a case – avoiding billions in liability for our clients.
