My son just found out a couple of months ago that he has a child. The last 12months the mother of this child told him that he was not the father. Now they are talking again, and she told him that he is the father. My son is in the Army, he said that he was told all he had to do is walk in to the hosptial and tell them the story and they will put him on the baby's birth certificate. We live in Texas. The baby was born in Texas. So my question is: Can you really go in to a hospital and tell them that you are the father of the baby and they will put you on a birth certificate without no documentation on being the real father. I keep telling him that he has to have some kind of documentation that he is the father of this child. Or he will have to go thru an adoption to be legally be put on the birth certificate.
