There is oral discovery and written discovery.
Written discovery consists of written questions that must be responded to in writing. Written discovery falls into three types of requests.
1) Request for Production of Documents
This form of discovery requires that a party produce documents relevant to their claim.
2) Interrogatories
This form of discovery consists of written questions relevant to the action.
3) Request for Admissions
This form of discovery requests that a party admit or deny certain questions.
There is also oral discovery. A common example of oral discovery is a deposition. A deposition is an examination of a party or person under oath. There will be a court reporter present to record the deposition. Some depositions are also filmed. Similar to trial, an attorney is allowed to ask questions of this individual who is referred to as the deponent.
The deponent’s attorney will be present and may object to the questions similarly to trial. The transcript of the deposition may be used at trial subject to certain limitations.
