How Illinois Family Law Works

Illinois family law is governed by the Illinois Marriage and Dissolution of Marriage Act (IMDMA), which focuses on fairness and the best interests of children. Even when emotions run high, the law encourages cooperation and equitable outcomes.

Some key principles include:

icon

Parental Responsibilities and Parenting Time

Determining how decisions for your children will be made and how time will be shared.

icon

Child Support

Calculated under Illinois’ “income shares” model based on both parents’ incomes.

icon

Spousal Maintenance (Alimony)

Determined using statutory factors, and in some cases, state guideline formulas.

icon

Property Division

Marital assets are divided equitably, not necessarily equally.

icon

Post-Decree Modifications

Custody, support, and maintenance orders may be modified when life circumstances change.

Understanding these principles early helps set realistic expectations and leads to smoother resolutions.
