A more thorough explanation:

A motion for reduction is a request made to a court to decrease the amount of child support payments. It is a type of motion to modify, which is a post-final-decree motion asking the court to change one of its earlier orders.

For example, if a parent is struggling to make their child support payments due to a change in their financial situation, they can file a motion for reduction to ask the court to lower the amount they are required to pay.

This type of motion is specific to family law cases and illustrates how parties can request changes to court orders when their circumstances change.
