A California Discovery Request (WI 300) is a form typically used in civil cases in California state courts. It is a discovery form that can be used to request documents, items, or information from another party in the case. The form allows the requesting party to specify the type of documents or information sought, including but not limited to depositions, interrogatories, requests for production, requests for admission, and other types of requests. The form also allows the requesting party to specify the time period, location, and other relevant information. There are three types of California Discovery Request (WI 300): Request for Production of Documents, Request for Admissions, and Request for Interrogatories.
