Hi I'm new here. Stumbled into this site as I was searching for answers. I have recently been contacted by the Child Support Agency. I was ordered to pay such amount to my ex as I am now working full-time and he is still on the dole. Centrelink has recorded a child care percentage of 50/50, althought through the years, I know and have wittnesses and evidence that I have more care of my son that his father does, but I had never bothered to change this through Centrelink. It just upsets me as it's unfair that since we have been separated (8 years ago) my son's father has never paid for my son's school fees, uniforms, books and I even buy them groceries because I want to make sure my son doesn't go hungry. I have worked hard through these years to have a better life for my son and now having a full time job, he has applied for child support. On January, he was wanting me to pay him money but says if I continue to pay for my child's school and education needs then he will advise child support that it is private. But now I am being hit with a bill for me to back pay. Sorry, it's a bit long lol but need some answers if there's a way for me to appeal for this?
