Post-Decree Modification in Chicago

Illinois Standards for Post-Decree Modification

The Illinois Marriage and Dissolution of Marriage Act applies different requirements depending on the provision a party wants to change. Courts generally consider the existing judgment, the circumstances surrounding its entry, later developments, and the evidence supporting the request. A change isn’t automatic simply because the current arrangement has become inconvenient.

Child Support & Maintenance Modifications

A child support modification or maintenance modification generally requires a substantial change in circumstances, subject to statutory exceptions and the language of the existing judgment or agreement. Relevant developments may include changes in income, employment, insurance costs, child-related expenses, or financial needs. Maintenance provisions must also be reviewed to determine whether and how they may be changed.

Changes to Parenting Time & Parental Responsibilities

Illinois law generally permits modification of parenting time when changed circumstances make it necessary to serve the best interests of the child. Requests involving allocation of parental responsibilities may concern significant decisions about education, health care, religion, and extracurricular activities. Changes to those responsibilities are subject to additional timing rules and statutory exceptions.

What We Evaluate Before Filing

Each request requires a fact-specific analysis. We examine the controlling order, compare past and current circumstances, and consider how the proposed change would affect the family.

Modification matters may involve:

• Modification of parenting time or decision-making responsibilities
• Child support changes based on updated financial or child-related information
• Maintenance modification under the judgment and Illinois law
• Parental relocation and related parenting schedule changes
• Complex income, closely held businesses, or high-value assets
• Difficult communication or high-conflict dynamics
