We Are Here for You

At Wisselman Harounian, we want every client that walks in the door to feel safe and expertly represented. To feel good about placing their trust in us, and to feel confident about what we can do to help them reach their goals. Every single case is important to us, and our mission is for every client of our firm — whether their case is big or small — to get the best outcome possible. Our full service family law firm also offers estate planning and prenuptial agreements.  We call prenups “the closest thing to divorce insurance“.  

We Excel at Life Transition Strategy

Every family has unique values, priorities, commitments, traditions and challenges. No two families are the same. When your family relationships get “complicated”, you can turn to us for help, because we are leaders in modern divorce counseling and family transition advisors.  We are the firm that women breadwinners and business owners turn to for guidance.  Our clients are professionals that need executive divorce counsel.  From the very first meeting, we will address  your immediate concerns, present a clear strategic roadmap, and create peace of mind.  Depending on your case, our strategy may include: pre-divorce planning, financial risk analysis, relationship exit strategy and confidential advisory before filing.  We also have very strong courtroom capability. If you are in a high conflict matter, or if you or your children need protection from an abusive spouse, we will not hesitate to get a court order (in some cases within 24 hours) so that you are safe in your home.

Individual Attention and Winning Results

As one of the premier matrimonial and family law firms on Long Island and in the New York Metropolitan area, we have redefined the law firm experience.  We are committed to providing smart divorce solutions and calm strategic guidance. You can depend on our compassionate team of attorneys to help you move forward with your life. Importantly, we firmly believe that not every case must end up in court with high stakes litigation.  We orchestrate favorable out of court resolutions in the vast majority of cases.  Our mission is to navigate our clients to the finish line with their dignity intact, and children and finances protected — in the short term and the long term.  

The longevity and success of our firm since 1976 is due to our promise to safeguard our clients the way we would our own loved ones. We are proud that we are a referral based practice. We do not take your trust for granted.

Committed to Your Peace of Mind and Well Being - We Believe Mental Health Is Wealth

Our commitment is to address all of the needs that arise from your family law matter  — especially the concerns we can’t see — like your mental well being, stability and clarity.  From Day One, we will do an assessment for you and your children, including domestic violence issues, to make sure that your needs are addressed. Our goal is to give you peace of mind so that you can move on with your life.

Licensed Social Worker on Staff - We’re in the Habit of Helping

We have a licensed master social worker on staff to help consult with our attorneys and provide referrals to clients, so that they can better cope with the full spectrum of their family concerns. We can help you with referrals for individual counseling, rehab and support groups, and specialists for children with special needs.

Licensed Mediators - Going to Court is Not Always the Answer

Sometimes settling out of court is the best option. Our attorneys and mediators are ready to help. Unlike many other firms, we encourage peaceful and civilized resolution of issues from the outset. Litigation is almost always a Plan B at our law firm. We can also counsel you regarding annulments, uncontested divorce, or legal separation in lieu of divorce.

Our Managing Partner, Jacqueline Harounian was recognized with the “Humanitarian of the Year Award” by UJA, a leading non profit organization, for her advocacy and service.  We also sponsor and support several charities that help individuals and children with cancer.

Prenups - The Closest Thing to Divorce Insurance.

This phrase is our trademark!  Our law firm handles nearly 100 prenuptial agreements each year. We believe that premarital financial counseling and disclosure of assets, debts, income and expenses is the route to a healthier and happier marriage. And in the event the marriage ends — just like an insurance policy — your prenup will make sure that you are not exposed to extreme legal and financial risk.

What our clients are saying

I can’t tell you how much I appreciate working with you. I have been hearing such horror stories from my clients about their lawyers…from being unresponsive to giving bad advice. I was so lucky to have found you!

- Former Client

Derrick Rubin advised my elderly Dad on his apt lease renewal. Time was of the essence and Mr. Rubin reviewed the lease immediately and met with us to over questions and concerns. He is extremely professional and meticulous, as well as patient and kind. Thank you!

- Former Client

Jackie Harounian is professional, very knowledgeable, responsive and above all, kind and understanding. Working with her during difficult situations became a pleasurable experience and I plan to work with her again in the future. I would suggest her and her firm to everyone.

- Former Client

Thank you very much for your help throughout my divorce. Your skill, patience, and calm disposition brought me reassurance during a very dark time. I appreciate everything you have done.
