According to Free Printable Certificates, there are several adoption certificate templates available. There are adoption certificates for children, pets, dolls and stuffed animals. Before adoption certificates can be issued, the adoption must be finalized, notes Adoption.org.
Adoption.org states that when a child is adopted, the original birth certificate is stored away with a state file of the adoption record. A new birth certificate is then issued identifying the adoptive parents. This is the same process even for stepchildren who have been adopted. The adoption certificate serves as a temporary document given to the adoptive parents, which remains in place until the new birth certificate has been received, according to Adoption.org.
