For those who do not want a completely open adoption, there is the option of semi-open adoption. Semi-open adoption is a great option to create an adoption relationship that meets the needs of a particular situation. Every adoption relationship is different, and semi-open adoptions can take many forms; a typical semi-open adoption involves communication without exchanging identifying information, along with sending pictures and letters on occasion.
A closed adoption is the type where there is totally no contact between the birth parents and the adoptive parents as well as the child. There is also no classifying information shared between families about each other, thereby effectively cutting possible contact between the two. Before the child joins the family, the adoptive parents are provided with non-identifying data about the child and his or her birth family. Once the adoption is concluded, all records are sealed. These sealed records may or may not become accessible to the adopted child once he or she turns 18, but this is dependent on the signed paperwork and local law.
Historically, the four primary reasons for married couples to obtain a child via closed adoption have been (in no particular order) infertility, asexuality, having concern for a child's welfare (i.e. would not likely be adopted by others), and to ensure the sex of the child (a family with five girls and no boys, for example). In 1917, Minnesota was the first U.S. state to pass an adoption confidentiality and sealed records law. Within the next few decades, most United States states and Canadian provinces had a similar law. Usually, the reason for sealing records and carrying out closed adoptions is said to be to "protect" the adoptee and adoptive parents from disruption by the natural parents and in turn, to allow natural parents to make a new life.
From the early 1950s when Jean Paton began Orphan Voyage, and into the 1970s with the creation of ALMA, International Soundex Reunion Registry, Yesterday's Children, Concerned United Birthparents, Triadoption Library, and dozens of other local search and reunion organizations, there has been a grass roots support system in place for those seeking information and reunion with family.
Closed adoption, not to be confused with sealed records, is an adoption in which the adoptive family and the birthmother never meet and know nothing or very little about one another. With the advent of open adoption, closed adoptions have become the exception in domestic adoption rather than the rule. The term closed adoption is most often used in relation to post-adoption contact, whereas the term sealed records is related to the access of legal documentation surrounding the birth and placement of the adopted child once the adoption is final. It is entirely possible to have a closed adoption and unsealed records or an open adoption with sealed records. The two practices are not mutually exclusive.
