Last April I was told that a former acquaintance thought she was "pregnant" with a child she claimed to be mine, although i do not remember sleeping with her. she never told me if she really was or not. she sent a picture of a baby to my wife in november and said she had the baby. she has told a mutual friend of mine that she never had a baby, and when she found out the friend knew me, she changed her story and said she had the baby and gave it up for adoption. how do i legally go about finding out if she ever had a child, and if she did and gave it up for adoption, what are my legal rights?
