Filing a Child Support Modification enables a parent to adjust the terms of a currently existing court order. A court may allow a modification of child support if a parent can provide evidence that their circumstances have significantly changed in such a way that it now makes sense for them to see their child more often. A significant change in circumstances will need to be demonstrated first to the court before being allowed to present evidence as to what is best for their child. Moving closer to the child is an example of a circumstance that might allow a modification on earlier rulings on custody. Another example is a new work schedule, that would allow a parent to spend more time with their child. Another example of modifying a child support or custody order is to show evidence that an ex-spouse has failed to provide for the welfare of the child.
