455.530. Grounds for modification of orders.

This law explains when court orders for support, custody, or visitation can be changed.

Changes to support, custody, or visitation orders can only happen if something big has changed and it helps the child or makes the order more fair.

1. Support or maintenance payments can only be changed for future payments, and only if there’s a big and lasting change that makes the current terms unfair.

2. Custody orders can only be changed if new facts show that the child’s or guardian’s situation has changed and the change would help the child.

3. Visitation rules can be changed if the change is good for the child.
