William F. Gramer

With more than 20 years of experience in litigation, I help my clients navigate through the often complicated and difficult process of divorce and contested probate matters. My work covers all aspects of family law, from negotiating and drafting prenuptial agreements, to litigating divorce, child support, alimony, custody, and domestic violence issues, as well as challenges to the probate of wills and trust administration matters. Although I attempt to minimize conflict and resolve your family matter by agreement, I am prepared to present your case to the Court when necessary.
I also have experience representing businesses, home owners, developers and contractors in a broad range of other civil litigation and transactional matters involving residential and commercial real estate, including construction disputes, partition, landlord/tenant, and land use, permitting and zoning matters.
The cases I handle are about helping people who are thrust into difficult, life changing situations, often for the first and only time in their lives and involving close family members. My experience handling life’s transactions and family disputes allows me to successfully represent clients through complex issues in overlapping legal areas.
As a husband and father of three, I enjoy spending time with my family and being involved in school and sports activities. As a family we enjoy camping and skiing in New England. I have also served as an elected member of the Tyngsboro Planning Board and Tyngsboro Board of Selectmen.
