If a divorced parent wishes to change a part of the original divorce order then they must understand the limitations. First any property settlements are final after the 42 day appeal time has expired. The only issues that are subject to modification are; child support, visitation, and alimony. The first two are always available for modification while alimony may require a certain set of facts specific to the particular case to become modifiable.
Generally child support may be reviewed and recalculated upon the occurrence of a 10% increase or decrease in either party’s income or some other material change in circumstance that would affect the support amount. Visitation may be reviewed upon the allegation of a material change in circumstance that is adversely affecting the children or is causing an interference with a party’s ability to have visitation with the minor child or children.
