Illinois divides marital property in 'just proportions' — meaning fairly, based on the specific circumstances of your marriage, not necessarily equally. Courts look at 12 factors including each spouse's financial contributions, career sacrifices, the value of property assigned to each person, and economic circumstances after the divorce. One important Illinois rule: marital property runs from your wedding day all the way to the final divorce judgment — so assets acquired even during a multi-year divorce process can still be marital property.
Illinoisuses equitable distribution, meaning the court divides marital property in a way that is fair — but not necessarily equal. The judge considers multiple factors including the length of the marriage, each party's income and earning potential, contributions as a homemaker, and the economic circumstances of each spouse.
Primary statute: 750 ILCS 5/503 (Property division), 750 ILCS 5/504 (Maintenance) — Illinois Marriage and Dissolution of Marriage Act
Illinois has a statutory formula for maintenance (alimony): you take 33⅓% of the paying spouse's net income and subtract 25% of the receiving spouse's net income, with a cap so the receiving spouse doesn't end up with more than 40% of the combined net income. This formula applies when your combined gross income is under $500,000. How long maintenance lasts is tied directly to how long you were married — roughly 20% to 80% of the marriage length for marriages under 20 years; for marriages of 20 years or more, the court can order maintenance for as long as the marriage lasted or even indefinitely.
Illinois has two rules that catch people off guard. First, marital property in Illinois runs until the final divorce judgment is entered — not until you physically separated or filed for divorce. If your divorce takes two years to finalize, income and property accumulated during those two years is still marital property, unless you formally file for legal separation. Second, Illinois has strict rules about claiming that your spouse 'dissipated' (wasted) marital assets — you have to file a formal notice of your claim before trial, and you cannot look back further than 5 years before filing or 3 years after you first knew about the dissipation.

Illinois is an equitable distribution state. This means courts divide marital property fairly — but not necessarily equally. The judge considers multiple factors including the length of the marriage, each spouse's income and earning capacity, and contributions to the marriage.

No. Illinois is a no-fault state for property division purposes. Adultery does not directly affect how property is divided, though it may impact other aspects of the divorce.
Illinois does not have a mandatory waiting period. However, the residency requirement is 3 months — at least one spouse must have lived in the state for this long before filing.
Based on Illinois law, the three most important questions to ask are: (1) Since Illinois marital property runs until the final judgment, what steps should I take to document assets and income during the divorce proceedings, and should we consider a legal separation to limit further marital property accrual? (2) Given the statutory maintenance formula, what is the guideline maintenance amount based on our incomes, and does the duration schedule give me enough time to retrain or re-enter the workforce — or is there a case to deviate from the guidelines? (3) Has my spouse dissipated any marital assets, and if so, what documentation do I need and what are the procedural deadlines for making that claim?
