Hello, My wife up and left with no warning in Jan. 05. 5 months later she called and told me she was pregnant and that she was in New York. The baby is mine, this has been established. I received a medical bill and it showed that my wife (we are now legally separated as of October 05') gave our doughter her maiden name. She has this name on her birth certificate and social security, etc. Is this legal? Do I have a right to change her last name to mine? I was not there for the birth, I came up a week later. So I did not have the opportunity to sign anything. Not sure if that plays a role.
