My ex and I agreed on our child support together. I did not have a lawyer representing me, he did. We agreed on $600/mo for 5 kids (ages 18-6) that we share equal time with. He is responsible for direct expenses. Recently he came to me saying that I am responsible for paying half the kids cars and car expenses, as they were not direct expenses. He makes more than 4 times what I make. Our medical responsibility for example, is 67/23. Anyways, I decided to download the child support calculator and see what it calculated my child support should be. I work part time, so I figured what it would be full time. I looked at the worksheet that was submitted in our divorce and the only adjustment was "overall financial condition" (other than health ins premium and child care). Is this possibly what he is keeping for the Direct expenses he pays? When I did the calculations, it told me I should be getting over $2k/month…a big difference from what I get. I just want to make sure I am using the calculator correctly. He threatened to take me to court over a car bill, and if he did, I might have to look closer at the child support amount. Everyone I have ever talked to pays more support for less kids.
