In some cases, people preplan for the need to make adjustments to a parenting schedule and can agree ahead of time that they’re going to simply apply the best interest of the child standard for any future consideration of child support. Absent that agreement, if someone were wanting to make a substantial change in the parenting relationship altering the parenting time schedule they either need to demonstrate an agreement to the parties, an endangerment to the emotional and physical welfare of the child or children. Or an integration meaning that the children are living with one parent or the other in a manner inconsistent with the provisions of the divorce degree.
