About me

Robert Grossman focuses his practice in the area of matrimonial and family law, and also practices in the areas of real estate, commercial litigation and appeals. Understanding that clients often prefer to resolve their disputes out of court, Mr. Grossman is an adept negotiator who seeks to work collaboratively with opposing counsel to devise creative solutions to complex issues. But, when settlement cannot be achieved and trial becomes necessary, he aggressively pursues his client's goals without losing sight of the repercussions. From the outset Mr. Grossman works with his clients to determine their goals and develop a detailed plan for each, often including the "thereafter." In his view, the absence of a properly developed plan could be compared to taking a trip by car to a new destination without directions or a map – you may eventually arrive at your destination, but not without unnecessary complications and delays.

Mr. Grossman's work in the field of matrimonial and family law began over a decade ago, when clients who benefitted from his representation in commercial matters sought his representation in matrimonial disputes. He is experienced in matters involving pre-nuptial and post-nuptial agreements, separation agreements, child custody and visitation, child support and spousal support (maintenance) issues, equitable distribution of assets and liabilities, valuations of assets including enhanced earnings, licenses, practices and businesses, as well as post-judgment enforcement and modification proceedings. Mr. Grossman is also experienced in appellate practice. His business and commercial experience allows him to see issues from a practical perspective and gives him an in-depth understanding of certain complex issues that often arise in matrimonial disputes.  Mr Grossman has also been called upon to act as a "special prosecutor" for certain local municipalities from time to time.

    While it is true that he is my boss, he is a consummate professional and I fully endorse him. His breadth of knowledge of the law is as impressive as his courtroom temperament, skill, and commitment to all of his clients. He is a true gentleman in every respect and is highly regarded and respected in the matrimonial bar. I wholeheartedly and without hesitation endorse him.
