The Illinois Domestic Relations Cover Sheet is a legal document that must be filed with the court when a party is filing a divorce, legal separation, or other family law matters within the state of Illinois. The cover sheet serves to provide the court with additional information about the parties involved in the case, including their address, number of children, and other pertinent information. There are two types of Illinois Domestic Relations Cover Sheet: the original cover sheet and the amended cover sheet. The original cover sheet must be completed and filed with the court when initiating the divorce or family law case. The amended cover sheet must be completed and filed with the court when bringing additional parties into the case or when changes have been made to the original petition.
