Long Island's Premier Divorce and Family Law Attorneys

If you are looking at our website, you may be going through some very tough times. You may have major, immediate concerns and are ready to proceed, or perhaps are in an early phase of the decision-making process. We get it! Our team is here to help you un-complicate your life when you need it the most. We do more than represent; we explain and educate about the law and the options along the way. We work as a team with each client all of the time. There are no exceptions.

It is simply no secret that Family and Divorce Law are very personal and emotional subjects that can be difficult for families to navigate. After all, it often means major changes in the dynamics and finances of the home. It can even mean litigating against each other in court. This very truth is the reason why most attorneys elect not to practice any of these areas, but we embrace the challenges and handle them all. There are few, if any, other law firms on Long Island that exclusively handles what we handle and only what we handle.

Finding a law firm is easy. The real challenge is finding the right group of professionals who can provide representation that’s thorough, effective, and fair during the entire process. Often, a case is not simply determined by how bright or forceful the lawyer may be, but by how much respect they have within the courts and with other lawyers. Our firm has a retired Family Law Judge on staff. Our attorneys are in court to interact with those within the system on a daily basis. We regularly represent people who work within the Court system when they face their own personal legal issues. Again, these three areas are the only types of law that we practice, and we do it every single day. We represent every type of person imaginable from ultra-high net worth to those on a shoe-string budget, fathers and mothers, young and not so young, professionals and stay-at-home parents, and the list goes on. We handle simple cases that settle quickly, as well as cases that ranked as some of the longest litigated. If within our practice areas, we have done it successfully before and will do it successfully again for many years to come.
