Illinois Appellate Court
Civil Court
Child Support
In post-decree litigation, court determined in 2/16 that total amount of father's child support arrearage, from 2009 to 2014, was $5,701. Court, in 2018, calculated mandatory statutory interest on arrearage as starting to accrue in 2/16. Court erred in failing to assess mandatory interest on father's arrearage beginning 30 days from the first missed payment. Court's determination of the amount of father's total arrearage was not an abuse of discretion. (REYES and BURKE, concurring.)
