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. The register places the office outside New York, so a complaint would go to the grievance committee of the Third Department, which admitted this attorney (22 NYCRR 1240.7(a)(2)).
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.
