In Family Law

By Law Offices of Bonnie Alexander

Before July 1 of this year, child support was awarded as a percentage of the paying parent’s income. This method gave no regard for the income of the primary residential parent, but instead focused only on the parent with whom the child did not live for a majority of the time. Although Illinois law has said that both parents have an obligation to support the child, the new law actually puts it into place. Public act 099-0764 has amended section 5 to the Illinois Marriage and Dissolution of Marriage Act (also known as the IMDMA). Whether you’re in the midst of a divorce or a paternity case, or currently give or receive child support, this new law radically changes the rules.

The new law, in effect as of July 1, 2017, sets about a major change to the child support system. The so-called “income shares” model looks at both parents income to determine the amount of child support. This statute provides for the court to consider both parents’ income, both parents’ working history, parenting time and parents’ additional expenses. As you can imagine, this is a massive change and will have significant impact for families with children.

In our next post, we’ll expand this topic and discuss the calculations for what is now called the Total Family Income.
