In Feb 2012 child support was awarded to me, with him owing arrears up to this date. At that time custody was joint with me being residentail parent. My ex husband and I have entered into an interim shared custody order for 6 months in June 2012. He has since filed for a decrease in child support eventhough the order has not been officially signed. Do I have a right to answer this Decrease in Child support petition? Can I file a Contempt of Court?
