When each parent is to spend significant time with the child, there is significant flexibility in arranging the shared custody. The child will essentially live with both parents in these cases—some parents prefer that the child spend one week with them, and the next with the other parent, while in other cases, the child will spend 3 or 4 days a week with one parent and the remainder of the time with the other. The parents will share the right to both physical custody and legal custody (decision-making authority). This, as well as the interaction that will naturally be required in sharing physical custody, makes it important that the parents’ relationship is amicable enough for the arrangement to succeed.
