What Illinois expects
Illinois abolished 'custody' in 2016. Parents must file a proposed parenting plan within 120 days of a petition. The statute enumerates required contents — decision-making by category, the schedule, transportation, relocation notice, and a right-of-first-refusal provision if the parents want one.
Governing law: 750 ILCS 5/602.10.
The honest trade-off
Exchanges land on the same two days every week, which makes it easy to remember, and no one waits more than four nights. The trade is that which parent has the weekend flips each week, so weekend plans need a two-week memory.
