Florida has no jurisdiction over him. You should speak to an Alabama lawyer about it, but I think you're going to have to open a child support case in the county where he lives.

From the facts you have written it does not appear that FL would have jurisdiction over him. You need to have an attorney in GA look into the case and determine what needs to be done. There might have been a fraud on the court if he knew exactly where you were, and published in the newspaper to avoid you finding out about him filing for divorce.

I agree with both of my colleagues. Additionally, you do not state how long ago this occurred and when you found out about it. You state that your daughter is now 19 which leads me to believe that it may have been a while ago. You have some timing issues and jurisdictional issues. Also, GA would have jurisdiction over child support if they had jurisdiction over your husband, they would NOT have had jurisdiction over parenting and timesharing if your child was in Florida the entire time. You should consult a GA attorney to see what can be done.
