This document discusses interrogatories, which are written questions sent by one party to another in a civil case that must be answered under oath. Interrogatories are part of the discovery process and are used to gather preliminary information before trial. The recipient has 30 days to provide full and complete answers to each interrogatory or object to specific questions. Failure to respond can result in a motion to compel being filed. While interrogatories provide a low-cost way to obtain information, depositions allow for more spontaneous questioning and follow-up.
