Birth Certificate

If you are not married, each hospital has their own policy in order to put the father's name on the birth certificate.

If you are not sure who the father is of the new baby (or if you are the father and you are not sure if you are the father), then either ask for DNA testing OR don't put your name on the birth certificate.

If the man signs the proper paperwork that is then sent to Austin, TX, and becomes a binding legal document in the State of Texas. The man is voluntarily acknowledging that he wants to be the of this child, even if it turns out he is not the bio-father.

FYI: Of course, my advice could change in the future, if the TX legislature makes a change the next time it meets.

I urge you to talk to a family law attorney before you sign the birth certificate.
