Serving Clients With Skill And Integrity

Any legal issue involving your family has the potential to impact your life for years to come. It is essential to retain the services of legal counsel who will develop effective strategies that will help you move forward on the best possible terms. I am Kevin Duffy of the law firm Marx & Duffy, LLP. Since 1983, I have devoted my practice solely to Family Law, handling complex divorce, child custody and support, property division, paternity, post-judgment modification and other related Family Law issues.

A substantial portion of my practice involves creating and negotiating prenuptial, postnuptial and marital settlement agreements. I am adept at preparing legally enforceable agreements that protect your immediate and long-term interests.

What Does It Mean To Have A Certified Family Law Specialist On Your Side?

I am certified by the California Board of Legal Specialization as a Family Law Specialist. Certification reflects an attorney's experience, knowledge and standing in the legal community. Furthermore, certified specialists must pass a test in their field of law and must demonstrate competency and professionalism by peer review. As a certified specialist, I am equipped to identify and implement a course of action that suits your needs.

In many cases, I am able to negotiate an effective resolution that meets my client's needs. If litigation is necessary, however, I will take an aggressive approach. Above all, I recognize that each case is unique and must be resolved in such a way that accomplishes your goals.

I have also been selected for inclusion in Northern California's Super Lawyers each year since 1996.
