Which term defines a change in child support payments based on substantial and continuing changes?

The term that defines a change in child support payments due to substantial and continuing changes is "modification." In the context of family law, a modification is a legal process that allows for adjustments to be made to existing child support orders when there are significant changes in circumstances.

Such changes could include variations in the income of one parent, changes in the needs of the child, or alterations in living situations, among other factors. The modification process ensures that the support amount is fair and reflective of the current situation, rather than being stuck to a figure that may no longer be appropriate due to new developments in either parent's financial or personal circumstances.

This term is distinct from reduction, which implies lowering an existing amount but does not necessarily encompass the broader legal process of updating terms. Enforcement refers to ensuring compliance with existing support orders, and termination indicates the ending of support obligations entirely, neither of which reflect the nuanced adjustments involved in changing payment amounts.
