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.
