Illinois Divorce Settlement Agreement Laws and Requirements

A divorce settlement agreement (also called a marital settlement agreement) in Illinois is a legally binding contract between spouses that resolves all issues arising from the dissolution of their marriage — including property division, alimony, child custody, and child support. Under 750 ILCS 5/ (Illinois Marriage and Dissolution of Marriage Act), Illinois follows equitable distribution — courts consider each spouse's contributions, dissipation, and other factors. The residency requirement is 90 days in Illinois before filing. Illinois recognizes no-fault divorce on the ground of irreconcilable differences — sole ground for dissolution since January 2016 reform. There is a no mandatory waiting period after meeting irreconcilable differences requirement. For spousal support, maintenance formula: (33.33% of payor's net) − (25% of payee's net), capped at 40% of combined net income.

Filing an uncontested divorce with a comprehensive settlement agreement is the fastest, most cost-effective path to dissolution in Illinois. Without a signed agreement, the court must resolve each disputed issue at trial — a process that can cost tens of thousands of dollars in attorney fees and take a year or longer. A well-drafted settlement also gives both spouses more control over the outcome than leaving decisions to a judge. Our divorce settlement generator creates a Illinois-compliant agreement covering all required terms. For marriages with children, pair it with a child custody agreement that addresses parenting time and decision-making authority.

Is Illinois a community property or equitable distribution state?
Illinois follows equitable distribution — courts consider each spouse's contributions, dissipation, and other factors. This directly determines how marital assets and debts are divided in a divorce. Your settlement agreement can override default rules if both parties agree.
How long does a divorce take in Illinois?
Illinois has a no mandatory waiting period after meeting irreconcilable differences requirement. After satisfying that requirement, an uncontested divorce with a signed settlement agreement can typically be finalized within weeks to a few months. Contested divorces with disputes over property, custody, or support can take 6 months to several years. Starting with a comprehensive settlement agreement is the fastest path.
Can a divorce settlement be changed after it is finalized in Illinois?
Property division terms are generally final and very difficult to modify. However, custody, visitation, child support, and sometimes alimony provisions can be modified upon showing a substantial change in circumstances. To modify, you file a motion with the Illinois court that originally approved the settlement. Both parties can also agree to modifications, subject to court approval.
