Skilled Representation In Key Legal Areas


We build relationships with clients over the long term since we will represent them in a variety of important legal areas, including real estate law, family law/divorce, and estate planning.

Although these three areas form the backbone of our current practice, we frequently represent clients in many other situations, including business formation, commercial litigation, felony and misdemeanor criminal defense, DUI defense, traffic violations and municipal law.

 We are creative lawyers who are able to discover hidden money in a system that has been engineered to repel scrutiny.


Help During A Difficult Divorce


“Harvey Arnoff and his team were invaluable in helping me through my difficult divorce. I was very distraught when I first met with him, and he immediately put me at ease by walking me through the process and advising on what information he needed to represent me to the best of his abilities. With his guidance I was able to deal with my overwhelming emotions and stay focused and organized. He answered my questions no matter how trivial they seemed, and his staff was also very responsive at all times. Most importantly I was able to keep everything in perspective and concentrate on being a good Mom to my children as we all dealt with this.”
