In a Village This Size, You Will Keep Seeing Each Other
Clarendon Hills covers less than two square miles. Most children here go through Prospect or Walker and then Clarendon Hills Middle School, a small part of the village is in Maercker District 60 instead, and nearly everyone shares the same downtown, the same Metra platform and the same school events. After a divorce, both parents are usually still at the same pickups and the same games for years. That is a practical reason to choose a process that ends with two people who can still stand in the same gym. Mediation and collaborative divorce are built for that. A parenting plan written for Clarendon Hills should say who attends what, how the children move between two homes a few blocks apart, and what happens if one parent moves outside District 181.
How Illinois Family Law Works
Illinois family law is designed to support fairness and the well-being of children, even in the most challenging circumstances. With Attorney Kari Cornelison’s guidance, clients understand their rights and responsibilities throughout each step of the process.
Important elements of Illinois family law include:
Parental Responsibilities and Parenting Time
Allocated under 750 ILCS 5/602.5 and 602.7. Parents share or divide decision-making over education, healthcare, religion and activities, and a parenting plan is due within 120 days of service.
Child Support
Calculated under the income shares model in 750 ILCS 5/505 from both parents’ net incomes and the overnight count, with a shared parenting adjustment once each parent has at least 146 overnights.
Spousal Maintenance (Alimony)
Governed by 750 ILCS 5/504. When combined gross income is under $500,000, a guideline formula sets the amount and the length of the marriage sets the duration. Above that, the court works from the statutory factors.
Property Division
Marital assets and debts are divided equitably under 750 ILCS 5/503, which is not always equally. Property owned before the marriage or received by gift or inheritance can stay non-marital if it has been kept separate.
Post-Decree Modifications
Orders can be modified when circumstances change substantially, and a move of more than 25 miles from a DuPage residence with the children requires notice and, if contested, court approval under 750 ILCS 5/609.2.
Understanding these laws helps you approach your case with confidence and realistic expectations.
