Birth Certificate Question?

When the babys born and father is not listed on BC
. Can u always go back too fill it in?

Each state is diff, but normally no, only.time that happens is if he wants his. Rights and he asks a judge for his name to be put on it.

depends on the state, if he establishes paternity then normally yes

I have no idea... my ex established paternity and got some custody, and I never had to add his name or change deans last name, I'm guessing the judge would have to order that,
