The Illinois Petition for Dissolution of Marriage Civil Union Children is a legal document used in the state of Illinois to end a civil union or marriage with children involved. There are two types of petitions: the Joint Petition and the Individual Petition. The Joint Petition is used when both parties agree to the dissolution of marriage or civil union and can agree on the terms of the divorce. The Individual Petition is used when one party does not agree to the dissolution of marriage or civil union or when the parties cannot agree on the terms of the divorce. The petition outlines the terms of the dissolution such as division of assets and liabilities, child custody and visitation, child support, and alimony. It also includes the filing fees, which must be paid to the court at the time of filing. The petition must be signed by both parties and notarized before it can be filed with the court. Once the petition is filed, the court will review the petition and issue an order of dissolution of marriage or civil union.
