A.S.
I am not familiar with OK law but from what I know in my state and several others child support is set based on child support guidelines (a formula) so your attorney and your ex's attorney should be able to review child support guidelines, agree on the number the program spits out and then just have a judge sign the child support order during an order hour (then there is no need for a hearing). You can't really argue about child support because it is a computer calculation and whatever is owed is owed. Check this out: http://www.okdhs.org/onlineservices/cscalc/
