Mark Christopher De St. Aubin is due to re‑register on the New York attorney register file of Sep 29, 2026. Admitted in 2016 in the Third Department, with an office in Atlanta, GA; next registration due Oct 2026. Since Jul 3, 2026 it has moved only through the routine two-year cycle.
What this status means on the register
On the register, “Due to re‑register” means the attorney has a biennial registration falling due or overdue: the rule asks for it within 30 days after the attorney’s birthday in each alternate year, and the record gives the month it is due. The value stays until the register records the filing or marks the registration delinquent, so the month can have passed; by itself it is not a finding.

How to confirm it officially
For a statement of Mark Christopher De St. Aubin’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division, Third Department, which admitted Mark Christopher De St. Aubin in 2016. The register places the office outside New York, so a complaint would go to that department’s grievance committee (22 NYCRR 1240.7(a)(2)).
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).
