In order to obtain a modification of an existing child custody or parenting time arrangement via motion, a hearing will be required. At this hearing, your lawyer will explain the substantial change in circumstances that justifies the modification, and how the child’s best interests will continue to be served following the modification (as well as how failing to grant the modification order would not be in the child’s best interests). Depending upon the case, the court can either grant or deny the motion, or even request additional information regarding the case.
