Grace Dennigan

After 30 years of practice, a couple of ideas resonate and prove true over and over.  One is that couples are much more satisfied with the terms of their divorce if they decide the issues for themselves rather than having a judge determine the outcome.  This notion of "owning it" led Grace to want to empower clients - to educate and empathize and provide clients with the skills to decide their own fate.  This has been actualized in the expansion of the practice into collaborative law and mediation.

Grace has tried countless cases and the emotional and financial toll does not equate with a superior result.  The decision a judge makes rarely reflects creative thinking or the personalities of the litigants.  In the collaborative process however, clients are encouraged to seek the result that really suits the individual or family without the constraints of litigation.  Mediation, which can be part of the collaborative method (or not), also promotes the parties' self-determination.  Although Grace is a seasoned litigator, she is a trained collaborative lawyer as well as a mediator and is dedicated to offering these services to the practice as an alternative to litigation for those clients looking for additional means of dispute resolution.

After completing law school, Grace became licensed in New Jersey and completed a judicial clerkship in Union County.  She became an associate at Carchman, Annich, Socher & Shuster, a Princeton law firm, before joining the Attorney General's office in 1987.  After a great deal of jury trial work there, she returned to private practice, concentrating on family law ever since.

In addition to her law practice, she teaches the Family Law for Paralegals course at Mercer County Community College as well as courses for the NJ Institute for Continuing Legal Education.

She has served as the Chair for the District VII Ethics Committee.  She is a member of the Mid Jersey Collaborative Law Alliance, the NJ Association of Professional Mediators, the Mercer County Bar Association and the NJ State Bar Association.

Elizabeth (Beth) Smith

Beth came to the practice of law over 12 years ago after working with families in crisis as a social worker for nearly 15 years. With this background, her focus as an attorney is two-fold.  Her first objective is to assist clients in defining their needs and goals for themselves and their families before, during and after a divorce.  The second is to work with persistence and professionalism to assist clients in divorcing in a manner that closely aligns with their needs and goals while minimizing the difficulty of the divorce experience.  A client recently recommended Beth as follows:


"Beth Smith is the best advocate you could ever have. Advocate - someone to fight for you, someone to support you, someone to argue for you, your champion. She was highly recommended and far exceeded my expectation of what working with an attorney on a divorce could be like.

She is highly professional, incredibly smart, resourceful, tenacious, tireless and caring. Let me say more about caring. Divorce is a stressful process and Beth helps you to make the best of it - she is calm, supportive, empathetic and when appropriate, humorous. She will help you work through your priorities, financial and emotional, give you all the options, assist you to make the best decisions, develop a strategy and work until she achieves your goals. She is also strong, and tough and aggressive if that's what the situation calls for."


In practice, Beth focuses primarily on family law issues: divorce, custody, domestic violence and DCP&P. She is as adept at complex litigation as she at trying to find the most economical way to resolve your matter.  Beth is a qualified Parenting Coordinator, maintaining a parenting coordination practice, assisting parents working through custody and parenting time issues in high conflict divorces. In addition to her family law focus, she is an experienced mediator in divorce and custody matters and serve as a court appointed Guardian Ad Litem.

Beth graduated from Hartwick College with a BA in political science and Spanish, followed by a Master's degree in social work from Fordham University, magna cum laude. She completed her law degree from the University of San Francisco, earning the Cali Award for excellence, and became licensed in New Jersey and New York in 2004. Prior to joining Dennigan Cahill Smith in 2008 she worked for the New Jersey Attorney General's Office as a Deputy Attorney General for three and a half years where she was in court three to four days a week honing her litigation skills as an attorney representing the Department of Child Planning and Permanency. Beth is a member of the Mercer County Bar Association, New Jersey Bar Association, American Bar Association, Mercer County Domestic Violence Task Force, and the Mid-Jersey Collaborative Law Alliance<https://www.mjcla.org/>.
