Martin F. Kane, II

Marty Kane has been a trusted attorney at McGrath & Kane since 1997, specializing in complex domestic relations law and criminal defense. With over three decades of legal experience, he has earned a reputation for his dedication to his clients and his comprehensive understanding of both family law and criminal law.

A graduate of Boston College School of Management (1988) and Boston College Law School (1992), Marty began his legal career at the Middlesex County District Attorney’s Office, where he served from 1992 to 1997. During his tenure there, he prosecuted numerous criminal cases, including more than 500 jury trials and over 1,500 bench trials across the District and Superior Courts. Marty also successfully argued a dozen appellate cases in the Massachusetts Appeals
Court, addressing both criminal and domestic relations issues.

Since joining McGrath and Kane, Marty has developed a robust practice focused on complex divorce cases, particularly those involving child custody and business valuations. He has also built a strong criminal defense practice, defending clients in both District and Superior Courts across the Commonwealth.

In addition to his private practice, Marty has been an adjunct professor of law at Boston College for over 20 years, sharing and teaching his expertise in domestic relations and criminal law. He is also an active member of several legal organizations, including the American Bar Association, Massachusetts Bar Association, Middlesex County Bar Association, and the Massachusetts Family and Probate American Inn of Court.

Marty’s leadership within the legal community is well-established. He is an elected member of the Executive Board of the Massachusetts Bar Association. He served as President of the Middlesex County Bar Association, where he played a key role in uniting local bar associations and establishing a bench-bar forum to foster collaboration between attorneys and judges. He has also chaired the Middlesex County Bar Association’s Probate and Family Court Conciliation Program for nearly 20 years, a program that has successfully resolved over 3,000 cases.

A passionate advocate for legal education and pro bono service, Marty has been a regular speaker and faculty member for Continuing Legal Education (CLE) seminars on topics such as domestic relations, post-divorce modifications, and criminal law. Marty has served as an Attorney Representing Children (ARC) and participates in the Lawyer for the Day programs in Probate and Family Courts in Middlesex, Suffolk, and Norfolk Counties.

Marty’s contributions to the legal profession have been widely recognized. He was named a Massachusetts “Super Lawyer” in 2010 and continues to hold that distinction today. He has also been nominated as one of the “Best Lawyers in America.” McGrath and Kane, under his leadership, is consistently ranked as a top-tier firm in domestic relations by U.S. News & World Report.
