A custodial parent has the parental responsibilities to make each day selections concerning upbringing and properly being of the child. these obligations encompass identifying who the child socializes with, the region and mode of schooling, which extracurricular sports the child will participate, religious beliefs of the child, and many others.
If both parents are custodial parents, then both must generally consult each other regarding all parental responsibilities.
also notice that the courts can change your agreed upon arrangement if the court deems it as inappropriate for the children.
