Semi-open adoption doesn't usually involve any post-placement, face-to-face visitation. The children involved don't normally have any direct communication with their birthparents. Like closed adoption, once a child reaches the age of majority in his or her state, they have the option of searching for or being searched for by their biological family. Unlike a closed adoption, those involved in a semi-open adoption usually have access to some basic information that can assist in the search process.
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.
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.
