How to confirm it officially

For a statement of Matthew James Hayes’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 James Hayes in 2026. 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, 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).
