Open adoption has slowly become more common since research in the 1970s suggested that open adoption was better for children. In 1975 the tide began to change, and by the early 1990s open adoptions were offered by a majority of American adoption agencies. Especially rapid progress was seen in the late 1980s and early 1990s - between 1987 and 1989 a study found only a third of agencies offered fully open adoption as an option; by 1993 76 percent of the surveyed agencies offered fully open adoptions. As of 2013, roughly half of US states consider them legally binding, however contact in open adoption is not always maintained.
It's equally important adopters understand that in a closed adoption little to no information will be exchanged with the birth parents, including their choice to arrange an adoption with the couple. This can feel like a distant business deal for some adoptive couples who want to know the nuances and personality of the mother of the child they're being placed with. Other adoptive parents may feel the separation of adoptive and birth parent eliminates possible instability an openly known birth mother's lifestyle may bring into a family dynamic. Also, in an open adoption, if communication is lost between the birth mother and adoptee, the child may become confused and hurt.
Closed adoption (also called "confidential" adoption and sometimes "secret" adoption) is a process by which an infant is adopted by another family, and the record of the biological parent(s) is kept sealed. Often, the biological father is not recorded—even on the original birth certificate. An adoption of an older child who already knows his or her biological parent(s) cannot be made closed or secret. This used to be the most traditional and popular type of adoption, peaking in the decades of the post-World War II Baby Scoop Era. It still exists today, but it exists alongside the practice of open adoption. The sealed records effectively prevent the adoptee and the biological parents from finding, or even knowing anything about each other (especially in the days before the Internet). The International Association of Adopted People does not support any form of closed adoption because it believes that closed adoption is detrimental to the psychological wellbeing of the adopted child. However, the emergence of non-profit organizations and private companies to assist individuals with their sealed records has been effective in helping people who want to connect with biological relatives to do so.
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.
Like other, more open adoptions, what a semi-open adoption looks like will vary based on the preferences of the birth parents involved. As prospective adoptive parents, you should prepare to be flexible on communication in a semi-open adoption, as birth parents’ comfort levels (and communication preferences) may change over time as you build a relationship with them.
Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
