Sean R. Weissbart, who has been named a "Rising Star" by Super Lawyers magazine, practices in the areas of trusts and estates and tax-exempt organizations.  Specifically, Mr. Weissbart's trusts and estates practice focuses on domestic and international estate planning, the administration of trusts and estates, and representing beneficiaries and fiduciaries in contested matters in the Surrogate's Courts.  With respect to tax-exempt organizations, Mr. Weissbart counsels  clients on matters from formation and obtaining tax-exempt status from the Internal Revenue Service to complying with state and federal tax-exemption laws and the avoidance of excise taxes and the unrelated business income tax.  Mr. Weissbart has also litigated against the Internal Revenue Service in the United States Court of Federal Claims and the United States Tax Court.

Mr. Weissbart is an adjunct professor of law at New York University School of Law, where he teaches Income Taxation of Trusts and Estates, and Fordham University School of Law, where he teaches Trusts and Estates Drafting.  He is also a regular faculty member of the Hawaii Tax Institute and publishes scholarly and practice-driven articles, which have been featured in leading journals, including The ACTEC Law Journal, The Journal of Taxation, and Estate Planning.  He is proud to serve on the boards of various philanthropic organizations, including as General Counsel to ment'or, an organization that sponsors the American team at the Bocuse d'Or (a biannual culinary competition in France), and as part of the Young Lawyers Division of the UJA Federation of New York.  Mr. Weissbart has been awarded the "Justice Award" by MFY Legal Services for his outstanding contribution to pro bono legal services in New York City.

Prior to joining the firm, Mr. Weissbart was an associate at the law firm of Patterson Belknap Webb & Tyler LLP in New York City.
