Denner Lamanna Fiduciary duty
Executives, directors, and partners owe duties that survive handshake deals. Breach litigation recovers losses from self-dealing, usurpation, and disloyalty in closely held and private company contexts. Without public company governance structures, closely held businesses depend on fiduciary duties as the primary check on insider abuse.
We advocate for you
Trial depth for fiduciary duty
The outcome of a fiduciary duty matter can affect your freedom, finances, family, career, or business for years. Massachusetts and federal deadlines move quickly; early counsel helps preserve evidence, shape strategy, and protect appellate rights. 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 assessment: Fiduciary duties, contract rights, and emergency injunctive needs evaluated within days. Emergency relief: TRO and preliminary injunction practice to preserve assets and confidential information. Focused discovery: Financial tracing, forensic imaging, and expert retention under BLS schedules. Trial preparation: Bench and jury trials for shareholder, trade-secret, and fraud disputes. Judgment & appeal: Enforcement and Appeals Court review with trial preservation in mind. Institutional defendants and opposing counsel deploy delay, denial, and resource advantages. Fiduciary duty matters deserve trial-ready counsel from Boston who builds for courtroom advocacy—not volume docket management.

In depth
Massachusetts fiduciary duty — what you should know
Educational overview of local law, data, and litigation context—not legal advice for your specific situation.
Shareholder and LLC control fights in Massachusetts
When partners become adversaries, oppression, freeze-out, and breach of fiduciary duty theories interact with operating agreements and buy-sell provisions. Massachusetts courts may order buyouts, dissolution, or damages—but only if the record supports reasonable expectations of minority owners.
Denner Lamanna litigates control disputes in the BLS and Superior Court with trial calendars that do not pause for informal negotiation.
Trade secrets and the first two weeks after departure
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.
