Divorced in 1998, modification in 2002, 2 children Mid teens
All are in Missouri.

No Changes since the Form 14 was filed in 2002.

What is the process to ask for an administrative review of Child Support? What type of information do I need to provide? WIll they request the same from Mother?

We have a guy here from the MO state who'll hopefully chime in.

Generally both of you will have to provide certain financial info, ranging from checkstubs to 1040's.

Information On Modification
To ensure child support awards are in line with changing circumstances, CSE conducts triennial reviews of child support orders. On non-TANF cases, CSE conducts reviews if requested. On a TANF (Temporary Assistance for Needy Families) or MO HealthNet case, CSE either performs a review on its own or at either parent's request.

In conducting the review, CSE decides if a modification is appropriate by determining:

1. if a child support award figured using Missouri child support guidelines differs by 20 percent or more from the existing child support obligation;
2. if a health insurance provision needs to be added to the order.

If three years have passed since the order was entered, last reviewed, or modified and either or both of the above criteria are met, CSE will initiate a modification of the order.

State of Missouri will use both incomes for a new form 14 calulation. Wouldn't be surprised that while you are looking to better yourself and make more money, the NJ will actually take a cut in pay so that you have to pay the higher expenses. For instance, if you were to make $100 and she makes $60. You will pay the percentage of what you make. I bet anything that she probably only makes $40 this time around so you will have to pay a higher percentage.

Higher proportion, yes, but on a lower overall amount. i.e. the joint tables will use $140 vs the prior $160 for the overall joint CS obligation.

So it might well be a wash.
