About James R.
James R. Duffy began his legal path in the classroom. He earned a B.B.A. from St. John’s University School of Law and went on to receive an LL.B. from Brooklyn Law School. Those years shaped his grasp of business principles and the mechanics of courtroom procedure alike.
He practices in New York and has built a career as a trial lawyer. He is a senior trial partner at Duffy & Duffy, PLLC, a role that places him at the center of the firm’s litigation work. In that capacity he directs trial preparation, manages witness development, and marshals evidence for contested hearings. He often appears in courtrooms where careful presentation and courtroom poise matter most.
Duffy’s colleagues say he brings a methodical approach to litigation. He prepares cases with attention to detail and emphasizes practical strategy over rhetoric. He handles pretrial motion work and jury trials, and he is involved in case assessment from intake through resolution. He also participates in client counseling on litigation risk and procedural timing.
Professional association ties include current membership in the New York Academy Trial Lawyers. That connection keeps him engaged with peers who practice trial advocacy in the state. He has maintained ties to local legal networks and to organizations that study trial technique and evolving case law.
Over the years Duffy has taken on the kinds of contested matters that test courtroom advocacy. He has worked across phases of litigation: discovery disputes, dispositive motions, and trial. He views trial work as a sequence of decisions that combine legal analysis and tactical choices. He also contributes to firm leadership by mentoring junior lawyers and organizing trial teams.
Outside the courtroom his work is mainly practice-driven. He spends most of his time preparing cases, meeting with clients, and supervising litigation staff. He adapts to changing rules and case law while keeping the immediate needs of a case in view.
As of 2026 he remains based in New York and continues to serve as a senior trial partner at Duffy & Duffy, PLLC. His current practice focuses on trial litigation in New York.
