Primary law and terminology
O.R.C. § 3109.04 (shared parenting). In Ohio, courts generally describe the schedule as a shared parenting plan. The court's decision is based on the child's best interests, not simply a parent's preferred percentage of time.
Joint custody and parenting time
No presumption; either or both parents may file a shared parenting plan.
Child preference
The court may interview the child in chambers; a guardian ad litem may be appointed.
Relocation and move-away cases
A notice of intent to relocate must be filed with the court that issued the order.
Changing an existing order
A change in circumstances of the child or residential parent plus best interests, with a harm-versus-benefit test.
Where to file
Under the UCCJEA the child generally must have lived in the state for the 6 months before filing (or since birth, if younger). Ohio distinguishes between 'sole' custody and 'shared parenting,' each with its own plan requirements.
