A child support order of 376.00 was put into place based off of a supposed base salary. He also pays 500.00 for another child from a different relationship. This order was based on one pay stub and only his supposed base salary. Also, In an argument he told me he had his boss alter his pay stub so I wouldn't get much. I've also learned that he grossed 160k last year. In NC a modification can usually be made every 3 years. In light of this new information would it be possible for me to try and get one now?
