Child support is always modifiable under Florida child support law, as long as the change would be at least $50 or 15% – whichever is greater. Any time a parent establishes the basic
requirements for modification, that parent may file a petition for modification of child support.
BASIC REQUIRMENTS FOR MODIFICATION
If there is a prior court order in place that requires child support , a parent may file for modification any time there is a “substantial change in circumstances.” The substantial change may consist of a change of income for either parent. The substantial change may also consist of a change in the overnight parenting pattern exercised by either parent. The Florida child support statutes allow a modification petition anytime the petition would result in a change in support of at least 15% or $50 (whichever is greater).
