is there a way to have my father added to my birth certificate?
As a practical matter, no. More importantly, amending your birth record so as to now show the name of your father would not have any effect on your last name as originally listed. In other words, your legal last name on the birth record would still be your mother's maiden name. (That was the surname given you by your mother when you were born. Since your mother was not married at the time she gave birth, she was your only legal parent and she could have given you whatever name she wanted. Subsequent establishment of legal paternity
does not result in an automatic change of the out-of-wedlock child's last name.)
At this stage of your life, the best and most expeditious means for you to accomplish what you are seeking to do is to simply petition the court for a legal change of name=========================
