Either parent can file a petition to the family court system to alter a custody arrangement. With that petition, the parent must submit an affidavit outlining "adequate cause" to have the custody order modified. Adequate cause must prove that one parent is a danger to the child's physical, mental, emotional and moral health. Another admissible reason to have custody arrangements altered is if one parent is not respecting the terms of the initial order.
If evidence that the child is being harmed is not proven, the petition will be denied. If it is accepted, there still remain some complicated proceedings to have the "legal decision making and parenting time" order modified.
