First call the bureau of vital statistics to see if you can do it by affidavit. You may need the acquiescence of the man who signed the birth certificate. If you cannot do it by affidavit, then you will have to "sue" the bio father to determine paternity. Once paternity has been established by a court-ordered DNA test, the court will order the birth certificate to be changed.
