Longyan Wei is delinquent on the New York attorney register file of Sep 29, 2026. Admitted in 2014 in the Second Department, with an office in Shanghai, China; next registration due Aug 2026. The status is the same in all 3 files we hold. The month shown is the next cycle’s; the delinquency concerns an earlier registration the register did not receive.
What this status means on the register
On the register, “Delinquent” means the attorney has a registration the register shows as due and not received. Under the rule a failure to register results in referral to the Appellate Division for disciplinary action; the register does not show whether a given attorney was referred. How many hold this status.

We show the 3 register files of the last twelve months (Jul 3, 2026, Aug 6, 2026, Sep 29, 2026). A change of standing between them is struck through in red; the routine birthday cycle is not.

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 Second 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.
