When my little girl was born, I thought that she belonged to my boyfriend. He naturally wanted his last name on her birth certificate. I was pressured to allow him to do so. Well, time passed by and her skin darkened and her hair kinked. Needless to say, she was not his. Now she has the last name of a man that is not her biological father. What can I do to change her last name? She is now 2 years old.
