How to confirm it officially

For a statement of J. Marcelo Arellano’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division, First Department, which admitted J. Marcelo Arellano in 2001. 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).
