I am in CA, and receive child support through DCSS. For purposes of calculating support, under tax information, I am listed as head of household with the children as my dependents. DCSS said it is done that way because I have them most of the time. I am a stay at home mom and ex claims the children on his tax return. Anyone have experience with an issue like this, and if I go to court can I have it calculated with him as head of household/claiming children.?
