Negotiate with your biological parents and/or their representatives through a confidential intermediary. This is only an option if your parents are still alive (if they are dead, it is usually easier to unseal adoption records). Use the intermediary to explain your reasoning for wanting the records unsealed. If you can reach a mutual agreement, the records can be unsealed.
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.
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.
