I have a problem. My friend was just contacted by a woman whom it had a one night stand with last year and she told him that she had a baby and it is his. Not only that she put his name on the birth certificate without him being present. He lives in California, I know that it is illegal to do this but now what does do. He does not want the child, that he never knew about. He is going to do a paternity test, but if the child is his he wants to give up his rights voluntarily. How does he do this?
