For a statement of Mariah Nicole Rivera’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 Mariah Nicole Rivera in 2019.

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).
