Digital Accessing Methods via Official New York State Portals

The New York Unified Court System provides centralized digital tools for public record retrieval. For most civil and criminal matters in 2026, the primary portal used by attorneys and the general public is the WebCivil and WebCriminal database networks.

To perform an effective digital lookup, follow this step-by-step procedure:

1. Access the Unified Court System Portal: Navigate to the official New York State Unified Court System website and select the specific case search module corresponding to the court type (Supreme, District, or Local Courts).
2. Select the County and Court Facility: Choose Nassau County from the county dropdown menu to restrict your search parameters to local dockets.
3. Enter Identification Criteria: Input the known parameters. You can search by party name (Individual or Business), Index Number / Docket Number, Attorney Name, or Judge presiding over the matter.
4. Review Docket Activity and Documents: Once the matching record appears, examine the docket sheet. For public cases, viewable documents can be accessed directly through the Electronic Document Delivery System (EDDS) or New York State Courts Electronic Filing (NYSCEF) system, depending on whether the case is mandatory e-file or paper-filed.
