Children deserve to receive financial support from both of their parents, whether a mother and father are married, unmarried, or divorced. In order to help unmarried or divorced parents share the costs of raising a child, a court may order one parent to make child support payments to the other. In Illinois, child support is calculated using the “Income Shares” method, which takes both parents’ financial circumstances into consideration. If a parent fails to fulfill his or her child support obligations, he or she can face serious civil and even criminal consequences. Child support orders may be modified later if one of the parents experiences a “substantial change in circumstances” that necessitates the change.
The “Income Shares” Model for Calculating Child Support
Before major changes were made to the Illinois Marriage and Dissolution of Marriage Act (IMDMA) in 2017, child support was determined using a simple percentage of the paying parent’s income. For example, if a parent had two children with an ex-spouse, he or she would pay a monthly child support payment that was 28 percent of his or her monthly take-home income. Currently, however, Illinois uses a different model to calculate child support. This calculation method takes both parents’ net incomes, as well as the amount of parenting time each parent has, into consideration in order to arrive at an amount that is fair and reasonable.
