My daughters mother left us around 8 months ago and has not been back since. She is on drugs and has been arrested for this. My name is on her birth certificate as father but she was in another county when she delivered and I did not make it in time to sign it. She has not helped with any type of support for our daughter and I really don't want anything from her. She did file her federal taxes and claim our daughter even though she has not been around for 8 months or more.. how do I file something to keep her from just showing up and taking her from me when she abandoned her for over 8 months now?
