How to Interpret Results
Each row links to the attorney's full public record. The status badge reflects the most recent state in the NY OCA dataset - "Currently registered" means the attorney is in active, compliant registration for the current biennial period. Any other status (Delinquent, Suspended, Disbarred) warrants direct verification with the NY State Bar before engaging services.
Year admitted reflects when the attorney was first admitted to the NY bar, not when they last renewed. A long tenure is informational only; always assess fit for your specific matter separately.
Frequently Asked Questions
Can I search by bar registration number?
Yes. Enter a 7-digit NY bar registration number in the search box. The tool will return the matching attorney record directly, if it exists in the NY OCA dataset.
Why does a search return multiple attorneys with the same name?
Common names like Smith or Johnson appear many times in a 429,000-record dataset. The results table shows city and year admitted to help you identify the right record. Click through to the full profile for additional detail including law school, office address, and registration type.
What does the status badge mean?
Status reflects the attorney's current standing in the NY OCA registration dataset. "Currently registered" means the attorney is in good standing and registered for the current biennial period. Other statuses - Delinquent, Suspended, Disbarred - indicate an issue; check the NY Courts attorney-services portal for the authoritative, real-time status before engaging an attorney.
How is this different from the main search?
This tool is structured specifically for attorney-record lookups, with result columns optimized for a verification workflow (status, city, year admitted) and clear guidance on interpreting what you find. The main search on /search covers the same database but is a general-purpose interface without the educational framing.
