Practice Areas


Business / Commercial Litigation

We have almost two decades of experience representing sophisticated corporate and individual clients in complex state, federal, and arbitral proceedings involving finance, banking, technology, life sciences, commercial real estate, and other industries. We have helped clients in close corporation disputes and other matters involving allegations of breach of contract, fraud, negligence, Chapter 93A violations, breach of fiduciary duty, breach of the implied covenant of good faith and fair dealing, and other commercial claims.


Real Estate / Land Use Litigation

We have represented corporations, individuals, and conservation entities in matters before the Land Court, Superior Court, and municipal boards, concerning boundary disputes, adverse possession, easements, trespass, zoning, and other issues.


Third-Party Discovery

We have extensive experience representing corporations and individuals in responding to third-party discovery requests. If you or your business have received a subpoena to produce documents and/or to testify in a lawsuit or other matter, Cosmas Law may be able to work with you to limit the potential burden of compliance.


Local Counsel to Out-of-State Law Firms

Cosmas Law welcomes the opportunity to serve as local counsel and share our expertise with out-of-state law firms who need assistance before Massachusetts’ state or federal courts, whether with lawsuits, requests for discovery for use in out-of-state proceedings, or other matters. Though located north of Boston, our firm has access to space downtown where we can host depositions or attorneys in town for hearings.
