About Me

Michael S. Karpoff  is a partner in the Princeton, N.J. office of Hill Wallack LLP and is a member of the firm’s Community Association Group and the firm’s Professional Licensing and Regulation Practice.

Mr. Karpoff is certified by the Supreme Court of New Jersey as a civil trial attorney and oversees the Community Association Group’s litigation. He has served as lead counsel for numerous plaintiffs in construction defect cases during the past 25 years.

In addition to community association law and litigation, Mr. Karpoff concentrates his practice in administrative law including professional and occupational licensing and regulation, construction code and zoning matters. Previously, as a New Jersey Deputy Attorney General, he represented professional and occupational licensing boards and other state agencies before entering private practice in 1984.

His practice now includes representing professional and occupational licensees before New Jersey regulatory boards. He also served as the attorney for the Highland Park Zoning Board from 1987 until 1996

In addition to being admitted to practice law in the states of New Jersey, Pennsylvania and New York, Mr. Karpoff is admitted to practice before the U.S. Supreme Court, the U.S. Court of Appeals for the Third Circuit, and the U.S. District Court for New Jersey.
