In closed adoptions, the identifying information of the birth parents and prospective adoptive parents are not known by the other party. Typically, all the arrangements and paperwork occur through a mediator, such as an adoption agency or attorney.
Semi-open adoptions can vary. Often facilitated by either an agency or an attorney, this arrangement involves birth and adoptive families having some level of communication but without identifying information being shared.
The identities of the adoptive parents and the birth parents are shared, and together, they have come to a mutual agreement on how involved they will be in one another’s lives.
