Thanks for your reply. Let me clarify a little more. I didn't sign the papers due to the threats to her as I had no knowledge of that at the time. I signed them due to the threats to me from her to push on the back child support to get me thrown in jail. It was after her seperation that I learned the reason for why she threatened me with that, but really her motivation at the time doesn't matter other than between me and her. My choice was sign or chance going to jail. So being my signature was made under duress would the consent stand up if I contested it now?
As for her "lost" custody at the moment I should of pointed out that he just has the temp custody while the divorce is being settled and her stuck with the visitation, etc. That part is mainly boiling down to the are in a small town and his family are important people in it's social structure so the law seems to be working more in his favor than it should.
