When you are in the middle of a divorce, probably the biggest worry is for the well-being of children involved. You are ending what was supposed to be a lifelong commitment and your children are confused and hurt; they may even think this divorce is their fault. Nothing could be further from the truth. You want the best for your kids and so does the state of Illinois. The state has several statutes that deal directly with child custody.
Chapter 40 deals with custody issues. It is called the Uniform Child-Custody Jurisdiction and Enforcement Act. It specifies that the court system has jurisdiction to enforce law that deals with children and custody in a divorce situation. A parent must file a petition for dissolving the marriage or for the custody of any children that are a part of this marriage. It must be filed in the county in which the person filing is a resident.
