Questions for Michael Roe about Illinois Child Support? Here’s a quick summary of the application of overnight calculations that affect actual child support.
Recent changes to Illinois divorce law have reshaped how courts handle child support calculations when parents share parenting time almost equally. These updates reflect the state’s ongoing efforts to align financial responsibility with actual time spent with children, a critical issue in modern family law.
Illinois courts determine child support under the Income Shares Model codified at 750 ILCS 5/505. This model allocates support based on each parent’s income and the proportion of time the child spends with them. The 2023 amendments to the Illinois Marriage and Dissolution of Marriage Act clarified that when each parent has the child for at least 146 overnights per year, the “shared parenting” formula must be applied, adjusting both parents’ obligations proportionally.
