Substantial Change
A substantial change refers to a significant, unanticipated, and lasting change in circumstances that can justify modifying an existing Florida court order for alimony, child support, or time-sharing. Examples include a major change in income, a relocation, or a shift in a child's needs. Florida courts require this high standard so that final orders are not reopened over minor or temporary changes.
