Deborah L. Thaxter

Deborah L. Thaxter has extensive experience in complex business litigation in both federal and state jurisdictions, with special emphasis on securities and corporate disputes representing corporations and their officers and directors, as well as general partnerships and public and private limited partnerships.

She has also taught and lectured extensively on state and federal trial tactics involving securities and class action litigation, as well as litigation involving trade secrets and restrictive covenants.

Before entering private practice, Deborah served as a law clerk to Hon. June Green in the U.S. District Court for the District of Columbia.

What do you focus on?

I have extensive trial experience in both state and federal courts, including bankruptcy courts, throughout the country, including the New England states, Delaware, Florida, California, New Jersey, Maryland, New York, Oklahoma, Ohio, Pennsylvania and Texas. I’ve also litigated extensively in the Chancery Courts of Delaware.

Over my decades of practice, I have litigated a variety of corporate control contests and regulatory enforcement actions. For example, I recently represented the CEO of a public company in federal court in Massachusetts in a civil enforcement action brought by the SEC, where the jury, after a lengthy trial, rendered a defense verdict for the CEO on all counts.

I have also litigated numerous cases involving trade secrets and non-competition agreements for software, distribution and financial companies in both federal and state courts in over a dozen states.

What do you see on the horizon?

Litigation attorneys need to be more willing to partner with clients through alternative fee arrangements and to adopt disciplined project and budget management strategies. I believe clients will continue to look for trial lawyers who have solid court room experience and who can use that experience to manage cases efficiently, avoid unnecessary discovery disputes and expenses and to identify, when appropriate, the alternative dispute resolution procedures that are most likely to succeed.
