Illinois Joint Petition For Simplified Dissolution Of Marriage is a legal document that allows couples to legally end their marriage in a streamlined, simplified process without having to go through the full court process. This type of dissolution is available only to couples who meet certain criteria, such as having a valid marriage, no minor children, and no more than $20,000 in marital assets. The petition must be signed by both spouses and filed in the circuit court of the county where either spouse resides. There are two types of Illinois Joint Petition for Simplified Dissolution of Marriage: an uncontested dissolution and a contested dissolution. An uncontested dissolution is when both spouses agree to the terms of the dissolution and submit the petition. A contested dissolution is when one spouse does not agree to the dissolution or the terms of the dissolution, in which case the court will have to decide the terms of the dissolution.
