Most parents assume the child support number in their order is fixed. Illinois law says otherwise — and knowing what can change it determines whether you act at the right time or wait too long.

In this episode, Attorney Nina Kelly of Sterling Lawyers walks through the key factors that can adjust child support in Illinois beyond what the formula produces — income changes, parenting time shifts, evolving child needs, broader financial changes, and the periodic review process most parents never knew existed.

In this episode, you'll learn about:

  • How child support in Illinois is calculated using the income shares model
  • What qualifies as a substantial change in circumstances
  • How income changes on either side affect the full calculation
  • Why parenting time shifts directly impact child support amounts
  • What types of child expenses can justify a modification
  • How broader financial changes factor into the court's assessment
  • How Illinois periodic review works even without a major triggering event

Listen in to discover what can adjust child support in Illinois so you know when to act, what to bring to court, and how to make sure the number reflects your family's actual situation instead of where things stood years ago.
