The "Validate Envelope Stage" extension is designed to assist attorneys in Illinois by validating envelope information related to attorneys and case parties. Specifically tailored for those using the CRIS (Clerk Restricted Information System) application, this tool allows attorneys to review pending envelopes from the Tyler Reviewer Application. Attorneys can verify information such as case parties, attorneys involved, existing documents, and future schedules for existing cases. For new cases, the extension helps in validating the active status of attorneys added to the envelope.

The extension's primary functions include extracting necessary data from the Tyler reviewer portal webpage and retrieving information from the CRIS Application based on the data obtained from the Tyler reviewer portal.
