On Long Island, many people have accumulated significant assets during their marriage. Many families elect not to divorce until the children are over the age of 18 which means that the marriage was of long duration and perhaps very financially complicated. When one or both parties to a divorce are considered to be of a high net worth, experienced attorneys to negotiate a deal or litigate are required.

The Law Offices of Seidner & Associates, P.C., has represented many high net worth clients with a cumulative value that is in the hundreds of millions of dollars. We have had to negotiate and litigate business interests, residential and commercial real estate, professional licenses, corporate matters, etc. as such are often largely or entirely marital property subject to equitable distribution in a divorce. In addition to determining family assets, our attorneys often must engage in activities to ascertain which party is entitled to what. We have also had to negotiate/litigate the validity of pre-and post-nuptual separation agreements. Valuations for affluent families may require involvement of experts, including appraisers, forensic accountants, and other professionals in addition to the attorney. We are ready for whatever we need to handle.

Our attorneys will assess every detail of our client’s financial life. We will guide clients toward an amicable resolution, if possible, or prepare for a complicated trial as needed. The Law Offices of Seidner & Associates, P.C. has relationships with many third parties who are often instrumental in helping us achieve our goals for our clients. We know that even a small error can have large consequences and there is no room for error. High Net Worth clients have many concerns that are unique to the issues involving substantial funds, including Trusts and Estates, etc. Because our firm regularly handles such matters, we are prepared for any situation.
