My ex had a child with another girl and they have recently split up. He told me today that she is filing for child support. So my question is does anyone know how this will affect the child support that I receive from him? I only get $450 a month for 3 kids as it is, and half the time he does not even pay that. Has anyone else had to deal with this? Does anyone have any idea how much they will lower the amount that I get for my kids? Will I have to go back to the attorney generals office and do the whole process over again? Oh and when I first filed for child support his other kid was already born so they did take that into account when figuring the amount he owed me.
