You need a partner who will not only look after your best interests,
but also be there for you when you need it most.


At Dennigan Cahill Smith, DSC, we are devoted to representing clients with family or divorce legal issues. We focus our personalized representation around the client, and his or her needs. Our attorneys are experienced in negotiating fair settlements, in pursuing court litigation, arguing motions, litigating trials, representing clients in mediation, and in the process of collaborative divorce. 

When it comes to important legal issues in your family, we can help inform you about your rights and guide you in your decision making. We work as litigators, mediators, parent coordinators, and guardians for children.

We represent clients in court and outside of court on all issues of family law.  Some of our work includes: trials, domestic violence, restraining orders, negotiating and drafting settlement agreements (MSA’s), and pursuing issues after-divorce (post-judgment). After-divorce issues often include: college expenses, cohabitation, termination of alimony, modification of alimony or moving out of state with children (removal).  We also represent individuals involved in DCP&P actions. 

We will always recommend the most cost   efficient manner of handling your case, without compromising your rights. Call 609-919-1600 or email to set up a consultation.
