A party may seek to modify an existing divorce judgment only to change spousal support, child support, child custody or parenting time (visitation) schedules. The modification will result in a document called a "Supplemental Judgment."
Except for changes in parenting time which can be sought at any time, there is a requirement to show an "unanticipated substantial change in circumstances" from the last order before a court will grant a change. One exception is that child support can be reviewed every two years, without a change of circumstances, but only through an administrative proceeding, not through a court motion to modify. Issues related to property settlement cannot be modified.
