How to confirm it officially
For a statement of Matthew Harris Rosen’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division, Second Department, which admitted Matthew Harris Rosen in 2019. A complaint about this attorney would go to the Second Department’s Grievance Committee for the Tenth Judicial District, which covers Nassau County, where the register places the office.
This page reads the register file of Sep 29, 2026, and the court system’s own search can be newer; the register shows only the current value, so a suspension that ended before the files we hold, or a censure, leaves no trace here (Appellate Division decisions are published through the court system’s Law Reporting Bureau).
