What is a Parenting Plan in Illinois?
A parenting plan in Illinois is a written agreement that outlines how parents will share custody and make decisions about their children after separation or divorce. Illinois courts require (or strongly encourage) a parenting plan as part of any custody proceeding.
The plan typically covers physical custody schedules, legal decision-making authority, holiday and vacation arrangements, transportation logistics, and communication protocols. Illinois uses the income shares model (changed from percentage in 2017) for calculating child support, which is directly influenced by the parenting time allocation in your plan.
While parents can draft their own parenting plans, courts in Illinois must approve any agreement to ensure it serves the best interests of the children. Having a well-structured, detailed plan increases the likelihood of court approval and reduces future disputes.
