Interrogatories are written questions that are asked and answered under oath as part of the pre-trial discovery process. They are used to supplementing evidence and help parties understand the facts behind a case. Interrogatories can be used to gain information from the opposing party that is not available through other means, such as depositions or requests for production of documents. There are two main types of interrogatories: standard interrogatories and special interrogatories. Standard interrogatories are a set of questions that are typically used in most civil cases. These are designed to elicit information about the parties, the facts of the case, and the legal theories that may be at play. The party who is served with the interrogatories must answer the questions and return the answers to the other party. Special interrogatories are questions that are tailored to the facts of a specific case. These interrogatories may ask for more specific information than standard interrogatories, such as details about a transaction or contact information for a witness. Special interrogatories may also include requests for documents or other materials that are relevant to the case. In most jurisdictions, a party must respond to interrogatories within a certain amount of time. If a party fails to respond or provides incomplete or evasive answers, they may be subject to sanctions, such as an order to pay the other party’s legal fees.
