A birthparent can sign anytime after birth, there is no thirty day limit. In our case it was nearly fifty days after birth and nearly forty-eight days after placement.

"CA does allow the bfather to sign before the child is born."

It all depends on how the birthfather is termed by the state, a presumed birthfather or an alledged birthfather. A presumed birthfather, a husband for instance who was in relationship with the woman within a certian time frame, can not sign before birth- his rights are the same as the birthmother's when it comes to relinquishing. An alledged birthfather, possibly a brief relationship or long term boyfriend, can waive his rights before birth and deny paternity- this isn't really the same as his signing relinquishments but in effect removes his right to parent. An alledged birthfather can choose to sign after birth, thus openly claiming his his paternity, and actively relinquishing his parental rights. This was the case in our adoption. Our child's birthfather did not want to deny he was this child's father in any way, and it was important to him that he be afforded the same process and respect given to the birthmother.

In the case of an unknown birthfather, well someone else will have to address that. My undestanding is that the process by which an unknown birthfather's rights are terminated doesn't start until after birth. I may be wrong.

If you can identify the type of adoption you are pursuing people can better answer your question about law.
