The social stigma of unmarried mothers, particularly during the Baby Scoop Era (1945-1975) rendered them social outcasts. By the 1980s the situation improved greatly and the vast majority of unwed mothers kept their babies. In a mother driven society after WWII infertile couples were also seen as deviant due to their inability to bear children. The social experiment of taking the children from "unmarried mothers" and "giving them" to adoptive parents became the norm during the BSE. These adoptions were predominantly closed. The records were sealed, biological mothers were told to keep their child a secret, and adoptive parents told to treat the child "as if born to".
Some states have confidential intermediary systems. This often requires a person to petition the court to view the sealed adoption records, then the intermediary conducts a search similar to that of a private investigator. This can be either a search for the birth mother at the request of the adoptee, or vice versa. Quite often, in the many years which have passed since the adoptee was born, a birth mother or female adoptee has both moved to another address, and married or remarried resulting in a change of her surname. While this can make the search difficult and time consuming, a marriage certificate may provide the needed clue as to the person's whereabouts. If and when the intermediary is able to contact the birth mother (or adoptee), she is informed that her adopted child (or birth mother) is inquiring about her. In the few states that have open adoption records, should this party indicate that he or she does not want to be contacted, by law, the information would not be given out. Upon completion of the search in which the birth mother agrees to be contacted, the intermediary usually sends the adoptee the official unamended birth certificate obtained from the court. The adoptive parents' application to an adoption agency remains confidential, however.
Open adoption is a form of adoption in which the biological and adoptive families have access to varying degrees of each other's personal information and have an option of contact. While open adoption is a relatively new phenomenon in the west, it has been a traditional practice in many Asian societies, especially in South Asia, for many centuries. In Hindu society, for example, it is relatively common for a childless couple to adopt the second or later son of the husband's brother when the childless couple has limited hope of producing their own child.
