i just had a baby girl in november of 2007. the mother of the child says she is my daughter however we are not together. my ex is engaged and living with a guy she has dated for 6 or 7 months. while she said she would call me when she was in labor she didnt. she even went one step farther and gave my daughter her fiance's last name. i have since went throught the paternity stuff. i live in new york state. how do i go about getting my daughter's last name changed to either my last name or her mother's last name. it is such a joke that a person would give their child the last name of a third party who has nothing to do with the situation. just one of the many games played by this woman
