This form can be used to ask a judge to change or end child support payments. Learn about the process and what other forms are needed.

Child support payments can be modified if there has been a substantial change in circumstances. A substantial change in circumstances can be:
- An increase in the needs of children;
- An increase in the ages of children;
- An increase in the cost of living for the children; or
- A change in either party’s financial situation (such as an increase or decrease in income or involuntary job loss of a party)
Learn more about changing or ending child support and use the Illinois Child Support Estimator calculator.
