How Illinois Calculates It

Illinois courts can order divorced parents to pay for college under 750 ILCS 5/513, making Illinois one of approximately 16 states with statutory authority for post-majority educational support. The statute caps tuition contributions at the University of Illinois at Urbana-Champaign in-state rate (approximately $33,558–$38,744 annually for 2024-25) and housing at UIUC double-occupancy residence hall costs. Courts allocate expenses between parents based on four statutory factors: each parent's present and future financial resources including retirement savings, the standard of living the child would have enjoyed if the marriage had not dissolved, the child's financial resources including 529 plans and scholarships, and the child's academic performance. Under Illinois law, educational expenses include tuition, fees, room and board, medical insurance, books, and supplies.

The statute also covers pre-college costs: up to five college application fees, two standardized entrance exams, and one prep course. Both parents and the child must complete the FAFSA. For FAFSA purposes, the parent who provided the majority of financial support—not necessarily the custodial parent—must submit their information. Illinois college contribution obligations terminate when the child fails to maintain a cumulative C average, turns 23 (or 25 for good cause), earns a bachelor's degree, or marries.

Military enlistment, incarceration, or pregnancy do not terminate the obligation. Unlike child support, which considers income, Section 513 examines total financial resources—including a new spouse's assets that reduce household expenses. Petitions are only retroactive to the filing date, so parents should file before college begins.

Frequently Asked Questions

Can Illinois courts order parents to pay for college after divorce?

Yes, Illinois is one of approximately 16 states where courts can order divorced parents to contribute to college expenses under 750 ILCS 5/513. This authority applies to divorced parents, those in parentage cases, and those who were never married. Married parents have no such legal obligation—the statute specifically addresses the financial disadvantages children face when parents separate.

What factors determine college contribution in Illinois divorce?

Illinois courts consider four statutory factors under Section 513(j): each parent's present and future financial resources including retirement savings, the standard of living the child would have enjoyed had the marriage continued, the child's own financial resources including 529 plans and expected scholarships, and the child's academic performance. Courts also weigh whether comparable public school options exist and how the chosen school aligns with the child's goals.

Is there a cap on college costs in Illinois divorce agreements?

Yes, Illinois law caps court-ordered tuition at the University of Illinois at Urbana-Champaign in-state rate (approximately $33,558–$38,744 for 2024-25) and housing at UIUC double-occupancy residence hall costs with a standard meal plan. Courts can exceed these caps only for 'good cause shown.' Parents can voluntarily agree to higher amounts in their settlement agreement, but courts cannot order contributions beyond UIUC rates without justification.

How does FAFSA work for children of divorced parents in Illinois?

Starting with the 2024-25 FAFSA, the parent who provided the most financial support during the prior 12 months must complete the form—not necessarily the custodial parent. If that parent has remarried, the stepparent's income and assets must also be included. Child support payments are now reported as an asset rather than income. Many private colleges also require the CSS Profile, which typically requires financial information from both biological parents.

Who controls 529 plans in Illinois divorce?

Under Section 513(h), 529 plans established before divorce are considered a financial resource of the child, not the parents, when calculating contribution obligations. Only one parent can legally own a 529 account. Divorce agreements should specify which parent controls the account and include protective language restricting withdrawals to educational purposes only. Violating such provisions can result in contempt of court charges.

Can I include college costs in my Illinois divorce agreement?

Yes, parents can contractually agree to college contribution terms in their marital settlement agreement, and Illinois courts enforce these agreements. In fact, negotiated agreements often provide more flexibility than court orders—parents can agree to pay for private schools, graduate programs, or costs exceeding the UIUC cap. Written agreements also establish contribution amounts and timelines that courts cannot impose without a contested hearing.

Does Illinois require college contribution for private school?

Illinois courts can order private school contributions, but the mandatory cap limits tuition to University of Illinois at Urbana-Champaign in-state rates unless a parent demonstrates 'good cause' for higher amounts. Courts consider whether comparable public options exist and how the private school aligns with the child's academic and career goals. Parents who want to ensure private school funding should negotiate it explicitly in their settlement agreement.

What age does college support end in Illinois?

Under Section 513(g), Illinois college support terminates when the child turns 23, earns a bachelor's degree, marries, or fails to maintain a cumulative C grade point average. The age limit can extend to 25 for good cause, such as delayed enrollment due to military service or illness. Graduate school, law school, and medical school are not covered—Section 513 applies only to undergraduate and vocational education.
