Parenting plans are a necessary part of custody proceedings in Illinois. If parents agree, they can submit one plan together. If they do not agree, each parent generally submits a proposed plan, and the court will order mediation unless there is a reason mediation would not be appropriate. If the parents still cannot agree, a judge will decide the disputed issues based on the child’s best interests.
