The previous Illinois child support law stated that the courts award child support based on a certain minimum of the non-custodial parent’s income, not taking into account the income of the custodial parent. The new laws that have taken effect on July 1, 2017 now considerboth parents income and awards child support based on an “income shares” model. This new law may cause some parents to pay more while others will be ordered to pay less than under the previous law.
