The Illinois Dormant Calendar is a tool used to track the expiration dates of certain statutory deadlines for filing claims against corporate entities in the state of Illinois. It includes all statutory deadlines imposed by Illinois law, including those related to the filing of tort claims, contract claims, and other legal actions. The calendar is updated annually to reflect changes in the state’s statutes. There are two types of Illinois Dormant Calendar: the Statute of Limitations Calendar and the Statutory Notice Calendar. The Statute of Limitations Calendar covers the time period in which a claim must be brought or a cause of action must be brought in order to be valid under the law, and the Statutory Notice Calendar contains notices of the deadlines imposed by the state for filing claims and serving legal documents.
