John J. McGlone III

Criminal Litigation

We have achieved tremendous success in a comprehensive range of criminal matters. We have represented individuals and corporations in a variety of contexts, including very sensitive and high-profile matters. Our broad criminal defense practice in State and Federal courts – at both trial and appellate levels – is grounded in our longstanding commitment to individual rights. The firm has successfully defended those charged with crimes in Massachusetts, including:

  • OUI
  • Motor Vehicle Homicide
  • Drug Possession and Drug Trafficking
  • Armed Robbery
  • Domestic Assault and Battery
  • Violation of 209A Restraining Orders
  • Rape
  • Assault and Battery with a Dangerous Weapon
  • Sexual Assault
  • Murder

We often handle grand jury investigations and advise clients on internal investigations of alleged criminal activity. Our experience with complex criminal litigation and the Massachusetts court system provides us with the means to expertly advise our clients facing simultaneous civil allegations and criminal investigations or prosecutions. GNCM also has extensive experience with those ancillary issues such as restitution, accord and satisfaction, and the effect a conviction has on a person’s driver’s license. We are dedicated to an aggressive defense and work tirelessly to exonerate our clients.

Domestic Relations

We have extensive experience in all aspects of domestic relations practice, including divorce, custody, child support, alimony property division, and guardianship. In any divorce or legal dissolution of the marriage, a court must be involved, as marriage is a legal contract. The authority of the court is required to settle many other related and complicated issues. GNCM has handled all domestic relations matters and has trial experience in these matters in every county in Massachusetts. Domestic Relations practice includes:

  • Divorce
  • Custody
  • Child Support
  • Alimony Issues
  • Property Division
  • Guardianships
  • Modifications
  • Contempt Actions
  • Pre-nuptial Agreements
  • Appellate Issues

Given the obvious sensitivities of the domestic relations practice, it is important to seek counsel with the appropriate experience and a proven trial record. Whether in negotiations or at trial, the firm’s lawyers expertly analyze the important issues involved, including assets and financial interests often at stake, business concerns, investments, stock options, pensions and profit-sharing plans, and the tax consequences related to the division of assets and setting support obligations.
