My case was dismissed July 16, 09... DNA proved that i am not the legal or biological father of my ex's two kids. I received a letter today saying I owe almost 3,000 in back child support and it has already gone to the dep. of treasurey and i am in legal trouble because it has exceeded 2000. How is this possible? DHR told me back in July that the case was closed. I have a letter of dismissal signed by Judge Bowens of Fulton co. superior court. and now I am getting this letter. These children are not mine and I have a letter of dismissal. Every attempt I have made to ensure that I would not fall through the cracks and this would not happen obviously did not work. What can I do?
