With over 25 years of experience in business litigation and complex commercial matters, Seth W. Brewster is a successful litigator and trial lawyer arising from his representation of a wide variety of businesses, developers, dealers, franchisees, manufacturers, distributors, corporations, shareholders, individual officers and directors, and service providers in corporate and commercial disputes. In the courtroom, Seth has successfully tried a number of cases to verdict. Clients who have observed Seth at trial have high praise for his skills. As an example, one client wrote: “Attorney Brewster’s dedication, knowledge, hard work and integrity were invaluable in achieving the favorable result in this litigation.”

With vast experience in commercial disputes and the antitrust laws, Seth brings innovative and creative approaches to advance the clients’ interests. For example, in a matter where an arbitrator ruled that Maine dealership law applied extraterritorially, Seth helped to amend the Maine dealership statute (so it applied only to Maine dealers) and made the legislative amendment retroactive to the pending case. In another matter, on behalf of a terminated distributor of fire-fighting equipment, Seth successfully argued that the dealer was entitled to the protection of the Maine power equipment dealership statute because the products required batteries for certain critical safety features.

Having represented both dealers/franchisees and manufacturers/distributors/franchisors, Seth’s ability to anticipate how the opposing party will argue a particular law (or fact) helps the client negotiate the complexities of a dealer termination.

Seth’s legal career also has included being a partner in one of Maine’s largest law firms, serving for three years on the legislative staff of U.S. Senate Majority Leader George J. Mitchell, and practicing law for three years at Ropes & Gray in the areas of securities and antitrust litigation.

When not practicing law, Seth is the Chairman of the Board of Trustees for Birch Rock Camp, a summer camp in Waterford, Maine focused on outdoor and wilderness education for boys between the ages of 7 and 15. Started in 1926 by his grandfather, the camp’s motto is “Help the Other Fellow.”
