Using a private lawyer:
You can hire a private attorney to take your case in front of a judge and ask that current child support be changed. You will probably have to give the lawayer money up front to start the case and you will probably have to pay court filing fees. It is usually much faster to use a private attorney for this proces.
Using your own lawyer also allows you to address other issues such as custody, visitation, or tax exemptions.
Doing it yourself:
You can write up court papers yourself and file them with the court clerk, asking that the judge set a hearing to decide if a modification of child support will be ordered. You should always talk to a lawyer and have your paperwork reviewed before you do this. You must understand the law that will be applied to your case and be able to give the judge reasons and present evidence that supports your request to change the child support order.
You can do it yourself through a Pro Se Modifiation process. You can request a Pro Se Modification packet by calling the OK DHS CSS CARE Call Center at 1-800-522-2922.
Using OK DHS Child Support Services:
You must send a written request to the OK DHS Child Support Services office that has your case. If you do not have a child support case with OK DHS CSS or you are unsure of where to send your request, you can obtain that information by calling the Child Support CARE (Customer Assistance Response Effort) Call Center at 1-800-522-2922. If you are opening a new case with OK DHS CSS, please note that you are requesting all child support services not just a modification of the child support order. Upon receipt of a request, the child support office will review the order and determine if it qualifies to modify. Using DHS usually takes a lot longer than using a private lawyer or going to court yourself.
