Parenting time is child visitation. It is the time the children spend with each parent. Physical custody of the children also define parenting time. A parenting plan outlines the time spent with each parent, and this document also defines vacation and holiday time. In all custody cases, a parenting plan is prepared, usually with provisions that dictate unpaid medical expenses and the payment of activities. Each parent must follow the plan. The court approves the initial parenting plan, but this may be modified if the need arises.
