How to confirm it officially
The register is published by the court system; PlainAttorney shows it as released. For a statement of an attorney’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division in the attorney’s department. A complaint about this attorney would go to the First Department’s grievance committee, which covers New York County, where the register places the office.
This page reads the register file of Sep 29, 2026; the court system publishes the file every few weeks, so its own search can be newer. The register shows only the current value: a suspension that ended before the files we hold, or discipline short of suspension such as a censure, leaves no trace here. Appellate Division decisions on attorney discipline are published in the New York Official Reports, online through the court system’s Law Reporting Bureau.
