On June 1, 2009, Ontario, Canada, opened its sealed records to adoptees and their birth parents, with a minimum age of 18 for the adoptee, or one additional year if the birth parents initiate the request. Both parties can protect their privacy by giving notice of how to be either contacted or not, and if the latter, with identifying information being released or not. All adoptions subsequent to September 1, 2008, will be "open adoptions"
Likely the most common arrangement in open adoptions is for the adoptive parents to commit to sending the birth mother photos of the child (and themselves as a family) each year, and short written updates, until the child reaches the age of 18. Often these photos and updates will be sent more than just once a year, such as the child's birthday or other significant events. Sometimes an intermediary is selected to receive and forward the updates, and sometimes it is done directly. This can be through mail or email. Some adoptions are more open than just sending photos and updates and include face-to-face contact. The amount of contact can vary greatly from just once in the first year, to multiple times annually throughout the child's life. Some of the adoptees raised in open adoption are now in adulthood and are writing about the experience of growing up in an open adoption.
Closed adoptions are rare in the United States, but remain common in international adoptions and were the norm in adoptions in the past, when families usually used an agency to adopt a newborn. The prospective adoptive family would put their name on a list, and wait for the social worker to make a match. The adoptive parents didn't know where the child came from, or who his or her birthparents were. The child might not have even known that he or she came into the family through adoption.
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.
