Both child and spousal support are based on each party’s income. If there is a substantial change in either spouse's income, the amount of support paid might be subject to change. To change the existing Court Order, you will need to go back to Court to modify the child or spousal support order or the order establishing the child custody and visitation arrangement. 

 
If your or your ex-spouse's situation has undergone a change and you now want to modify an existing, it is important to speak with an attorney to discuss the options and develop a plan for identifying and obtaining important information to establish whether your ex-spouse is now making more money or the spouse to whom you are making payments is now making more money or is self-sufficient.  or the spouse receiving support has higher earnings or is now self-sufficient.
