When a child is adopted through a closed adoption, the records of that adoption are sealed by a judge to make the transaction private. Biological parents will sometimes do this if they do not want to be contacted by their biological child, or if the parties involved agree that it is best if certain information be anonymous. But sometimes a child may grow up and want to contact his biological parents, or she may need to know her parents in the event of a hereditary illness or risk that requires knowledge of family medical history.
For children in open adoptions, the toughest challenge may come when a birth parent who’s been visiting or calling suddenly vanishes or drifts away. The trigger can be a move to a new job, a marriage, or a personal problem, such as drugs or alcohol. In some cases, a birth mother may not feel worthy of contact, or she may get the message from the adoptive parents that she’s not welcome.
Choosing between an open and closed adoption depends entirely on the adoptive family's preferences. It's strongly advised that couples that do not entirely support an open adoption should not engage in one. However, it's more rare to find an agency or attorney that is completely comfortable with a closed adoption and will not suggest a semi-open adoption to a birth mother.
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.
