The Illinois Petition For Dissolution Of Marriage-No Children (Pro Se) is a legal document that is filed with the court in order to begin the process of terminating a marriage in Illinois when there are no children involved. It is completed and signed by the petitioner and provides information about the couple, their marriage, and their agreement to end it. The petition can be filed in either a joint or separate format. In a joint petition, both parties agree to the dissolution and sign the document together. In a separate petition, only one party signs the document and the other party must be served with notice of the dissolution action. There are two types of Illinois Petition For Dissolution Of Marriage-No Children (Pro Se): Uncontested and Contested. An Uncontested Petition is one in which both parties agree to all terms of the dissolution, including division of property and debts, alimony, and other matters.
