Sean P. Gaynor, Esq.

Family & Criminal Law | New Jersey & New York

Sean is an experienced litigator who understands that every case requires particularized attention and detail.  He approaches every case with a “two track” mentality: while Sean tries to settle cases as early in the process as possible, he is also preparing the case for trial from day one in case a fair settlement does not come together.  This strategy allows him to always stay one step ahead of his peers, which can often lead to more favorable terms for his clients.  Conversely, Sean’s trial experience allows him to prepare his clients for the range of possible outcomes that a trial can bring so they can perform an adequate cost-benefit analysis of moving forward versus settling their case.

Sean understands that some in some cases, for whatever reason, settlement will not be appropriate.  If a case needs to proceed to trial, Sean’s initial preparation becomes all the more important, and he is always prepared and ready to ensure the best possible outcome for his client.  In addition to trying cases, Sean has significant experience preparing witnesses for the stresses and anxiety of testifying so that they can put forth their testimony in a manner that is comprehensive and understandable for the judge or jury.

Prior to joining Daly & Associates, Sean was an Assistant Prosecutor with the Morris County Prosecutor’s Office.  Sean was assigned to the Trial Team, where he regularly handled large caseloads quickly and efficiently.  Sean has experience with nearly all aspects of criminal law, including charges related to possession and use of firearms, sexual assault, domestic violence, robbery, controlled dangerous substances, burglary, and more.  He handled multiple cases subject to New Jersey’s “bail reform” law, and has experience with both grand jury and jury trials.  A staunch advocate for victim’s rights, Sean attended the prestigious Gunderson Finding Words/ChildFirst training, where he was trained on handling forensically sound interviews of children.

Since joining Daly & Associates in 2019, Sean has devoted the majority of his practice to family law clients, handling a wide variety of cases dealing with nearly every area of family law.  Sean continues to hone his trial skills and has tried cases relating to child custody and parenting time, business valuation, domestic violence, and more.  Sean regularly handles all types of family law matters, including matters involving custody and parenting time, alimony, child support, life and health insurance, financial protection, and division of assets such as a business, real property, stock options, restricted stock units, retirement accounts and cryptocurrency.

Sean is a graduate of the Catholic University of America, where he earned a B.A. in Politics, and The Columbus School of Law, where he earned his J.D.  In law school, he participated on the school’s National Mock Trial Team, tried misdemeanor-level cases in the Prince George’s County State’s Attorney’s Office’s Criminal Prosecution Clinic, and interned at the Warren County Prosecutor’s Office’s Major Crimes Unit.  After graduating law school, he clerked for the Honorable Ann R. Bartlett in Warren County during Judge Bartlett’s tenure in the family division.  During his clerkship, Sean was trained as a mediator and successfully mediated a number of family law cases to resolution.

Sean is admitted to practice in the State of New Jersey and the State of New York.  He is a Member of New Jersey State Bar Association and the Morris County Bar Association.  He is actively involved with the Family Law Section on both the state-wide and county-wide level.  He is a member of the Family Law Section’s Young Lawyers’ section and also serves as a volunteer attorney for the Battered Women’s Legal Advocacy Project, where he assists victims of domestic violence in obtaining Final Restraining Orders against their abusers.

Outside of his law career, Sean volunteered as the coach of Union Catholic Regional High School (his alma mater)’s Debate Team for 15 years, where he worked with students to hone their public speaking skills and learn about various topics affecting both the United States and the rest of the world.  He now enjoys spending time with his wife, Kaitlin, and his two young children, Daniel and Abigail.  In the summer, if you can’t find Sean at the office, he is probably playing in a pool with his kids.
