"In 2012, the Korean National Assembly implemented the Special Adoption Law that explicitly discourages sending children abroad," according to CNN. Under the law, birth mothers must wait seven days before relinquishing the child. If a mother chooses adoption, her consent must be verified and her child's birth registered. Finally, a mother may choose to revoke the adoption up to six months after her application.
