Even when a custody and parenting time agreement has been going smoothly, you can never really predict how your former spouse or parent of your child will act in the future. In some cases, the other parent may start to deviate slightly from a custody agreement. This turns into a complete refusal to follow your court-ordered agreement. In other situations, the other parent my suddenly make changes to your agreement and fail to pick-up or drop-off your child at the agreed location and time. This is very problematic and illegal.
