Child Support Information

Effective July 1, 2017 Illinois enacted a new method of calculating child support payments known as the Income-Shares model. The Income-Shares model is to be used to reach any determination regarding support made after July 1, 2017. 

More information on the Income-Shares model will be updated shortly. Until then, please consult the following link maintained by the Illinois Department of Healthcare and Family Services and resources contained therein to guide yourself: https://www.illinois.gov/hfs/ChildSupport/parents/Pages/IncomeShares.aspx

After the Court has determined a child support amount, the Court will enter a Uniform Order for Support.  The Uniform Order of Support will state the following:

  • amount of child support payment
  • frequency of payments (i.e., weekly, bi-weekly, bi-monthly, monthly)
  • who is responsible for providing health insurance for the child or children
  • percentage of uninsured medical costs for which payor is responsible
  • whether payments are to be deducted from payor’s paycheck or payor is responsible for making the payments directly
  • whether the payments are to be paid directly to the payee or to the Illinois State Disbursement Unit
  • termination date for support payments
  • amount of penalty for late support payments

The Illinois State Disbursement Unit (ILSDU) is the payments processing center for all Illinois child support payments. The ILSDU processes child payments from the payors and issues checks or direct deposits to the payees. 

The ILSDU website is www.ilsdu.com.  On this website, you can view payments and disbursements that have occurred within the last 30 days.
