Trusted Boston advocates
Fiduciary conflicts, trade secrets, shareholder fights, and balance-sheet litigation where control, reputation, and enterprise value are on the line—in the Business Litigation Session and federal court. Denner Lamanna represents clients in business disputes where the outcome reshapes companies—not just resolves a single invoice. That includes fiduciary duty claims, trade secret misappropriation, partnership dissolution, and contract litigation with fraud or punitive theories.
We advocate for you
Shareholder fights, trade-secret theft, and fiduciary breaches can freeze assets, destroy enterprise value, and end careers overnight. Massachusetts Business Litigation Session schedules move fast—and unprepared parties lose injunctive battles in the first two weeks. Once a TRO expires or evidence walks out the door with a departing employee, recovery may be impossible even if you ultimately win on the merits. Employee departures triggering non-compete and trade-secret disputes move on emergency timelines. Forensic imaging, customer list tracing, and ex parte relief determine whether a client keeps market share or loses it permanently. Post-2018 non-compete reform changed enforcement analysis. Both plaintiffs seeking injunctions and executives responding to cease-and-desist letters need current statutory guidance—not boilerplate templates. Denner Lamanna follows a disciplined process—Rapid case assessment: We evaluate fiduciary duties, contract rights, emergency injunctive needs, and forum—BLS, Superior Court, or federal court—within days of engagement. Emergency & preliminary relief: TRO and preliminary injunction practice to preserve assets, customer relationships, and confidential information when departures or breaches threaten irreparable harm. Focused discovery: Forensic imaging, financial tracing, depositions, and expert retention under BLS or federal discovery plans designed for commercial complexity. Trial preparation: Bench and jury trials with financial and technical experts—shareholder oppression, trade secrets, fraud, and contract disputes. Judgment enforcement & appeal: Post-judgment collection, Appeals Court review, and coordination when parallel criminal or regulatory exposure exists. Institutional defendants and opposing counsel deploy delay, denial, and resource advantages. Business litigation matters deserve trial-ready counsel from Boston who builds for courtroom advocacy—not volume docket management.
Emergency injunctive relief is often decided in the first 14 days—speed of counsel engagement matters.
Massachusetts context
The Business Litigation Session and specialized commercial dockets move faster than general civil tracks—TRO practice often decides outcomes.

Overview
Denner Lamanna represents clients in business disputes where the outcome reshapes companies—not just resolves a single invoice. That includes fiduciary duty claims, trade secret misappropriation, partnership dissolution, and contract litigation with fraud or punitive theories.
Massachusetts Business Litigation Session cases demand early case-management discipline, focused discovery, and counsel comfortable with sophisticated financial and technical evidence. We staff accordingly.
