Open 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.
In no event should the contact be allowed to become substantial enough to undermine the primacy or security of the adoptive parents' relationship with their child. In the case of open adoption, there are only a few absolutes governing how much contact birth parents may have with the adoptive family. In some cases, the adopted child may know his birth parents' names, contact information, and basic information about their lives, but not really have any direct contact with them.
