Some judges enforce co-parenting vigorously, others only pay lip service.
In all fairness to them, most judges do not know how to handle delicate family matters and they would welcome and encourage parents to resolve such important issues between themselves and keep such matters out of the courts and within the family circle. In the event you are not able to mutually agree on a shared parenting plan, you might want to consult a family counselor or mediator. Each family is unique in the way it functions. The less detailed your agreement, the more contact you will need with each other. A carefully planned agreement allows family members to decide for themselves what will be best for their special needs.
