I have 4 children with my ex wife. My visitation was modified to have the children 26% percent of the time in 2007, I still pay child support at 10%. They did not do a disso master for it either. Can they go back to when it was made an order and retroactive it. Or do I have to have it all changed through the courts again? I can barely feed them and put them in the lifestyle she has made for them which make me look bad to them as they always complain. I was told I would have to pay more since I remarried and have another child. Is this true also? My last child was a huge surprise as we thought we could not have any children can I get made to pay more to my ex wife for this?
