When it comes time to have signatures on my unborn baby's birth certificate... If I am unsure which man is the father and they both are aware of that, what should I do? Will I get in trouble if my fiance signs the certificate (he is more than likely the father) and i turns out to be the other man's child? What should I do? He has been there throughout the entire pregnancy and the baby will have his last name and everything. What to do?
