Last Oct. 30, 2007 the mother of my son signed over custody to me and all her parental rights. It was just a notarized letter. She hasn't had any contact with me or our son since December 25th, 2007. We were not married. She is now married. Can she and/or her husband come back and take the child? No one is named as father on the birth certificate. We live in Florida, would no contact for almost a year be abandonment? Thank you.
