Marshall is among a small group of lawyers in the Boston area who dedicates his practice almost entirely to handling trust, estate, and fiduciary disputes. Together with his colleagues who maintain a similar practice, Marshall has helped establish Goulston & Storrs as the preeminent probate and fiduciary litigation firm in Boston.

Trust and estate litigation is a specialized area of the law that can be highly emotional and personal, and of immense importance to the parties involved. A keystone of the firm’s fiduciary litigation practice is to understand each client’s unique circumstances and goals in order to help them navigate all aspects of a particular matter in the most efficient and effective manner possible.
