Illinois Child Custody Agreement Laws and Requirements

A child custody agreement in Illinois must comply with state-specific statutory requirements to be approved by the court and enforceable as a binding order. Both parents can negotiate their own agreement covering legal custody, physical custody, visitation schedules, and decision-making authority — but the agreement must ultimately serve the best interests of the child as determined by a Illinois judge. Under 750 ILCS 5/600–610 (Illinois Marriage and Dissolution of Marriage Act, Article VI), Illinois courts apply the best interests of the child standard when evaluating custody arrangements. Illinois law provides no presumption for joint or sole allocation; courts use 17 best-interest factors under §602.7. Regarding a child's input, child's wishes considered based on maturity — no fixed age threshold. Illinois requires 60-day written notice required for moves more than 25 miles (within Illinois) or any out-of-state move when a custodial parent plans to move. A parenting plan is required — each parent must submit a proposed parenting plan or joint plan within 120 days of filing.

Without a written custody agreement, Illinois courts make all decisions about parenting time, legal custody, and physical custody based on statutory factors — often resulting in outcomes neither parent prefers. A comprehensive child custody agreement gives parents control over the arrangement while satisfying Illinois's legal requirements. Illinois follows the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) for interstate custody matters, meaning the child's "home state" generally has exclusive jurisdiction over custody proceedings.

Illinois Child Custody Agreement FAQ

Can parents make their own custody agreement in Illinois?
Yes, parents in Illinois can create their own custody agreement without going through a contested court hearing. A well-drafted agreement covers legal custody (decision-making), physical custody (living arrangements), visitation schedules, holiday arrangements, and dispute resolution. The agreement must be submitted to the Illinois court for approval — the judge will ensure it serves the child's best interests. Use our custody agreement generator.
What factors do Illinois courts consider in custody decisions?
Illinois courts evaluate the "best interests of the child" using statutory factors that typically include: each parent's ability to provide care, the child's relationship with each parent, the child's adjustment to home and school, each parent's physical and mental health, history of domestic violence, the child's preference (if old enough), and each parent's willingness to support the other's relationship with the child.
How do I modify a custody agreement in Illinois?
To modify a custody agreement in Illinois, you must demonstrate a substantial change in circumstances since the original order — such as relocation, change in the child's needs, parental unfitness, or domestic violence. Both parents can agree to modifications, which must be approved by the court. Contested modifications require a hearing where Illinois courts again apply the best interests standard.
What is the difference between legal and physical custody in Illinois?
Legal custody refers to the authority to make major decisions about the child's upbringing — education, healthcare, religion, and extracurricular activities. Physical custody determines where the child primarily resides. Illinois courts can award joint or sole legal custody independently of physical custody, so one parent may have primary physical custody while both share legal custody.
