In a confidential adoption, neither the adopter nor the birthparents know each other, nor do they ever meet. Instead, all the arrangements and paperwork occur through a middleman, usually an adoption agency or an attorney. Some people call this a closed adoption, although I prefer the terms confidential and traditional because they sound nonjudgmental. A confidential adoption doesn't mean that the adopters and birthparents know nothing about each other. What it means is they have no identifying information about each other.
Some states have confidential intermediary systems. This often requires a person to petition the court to view the sealed adoption records, then the intermediary conducts a search similar to that of a private investigator. This can be either a search for the birth mother at the request of the adoptee, or vice versa. Quite often, in the many years which have passed since the adoptee was born, a birth mother or female adoptee has both moved to another address, and married or remarried resulting in a change of her surname. While this can make the search difficult and time consuming, a marriage certificate may provide the needed clue as to the person's whereabouts. If and when the intermediary is able to contact the birth mother (or adoptee), she is informed that her adopted child (or birth mother) is inquiring about her. In the few states that have open adoption records, should this party indicate that he or she does not want to be contacted, by law, the information would not be given out. Upon completion of the search in which the birth mother agrees to be contacted, the intermediary usually sends the adoptee the official unamended birth certificate obtained from the court. The adoptive parents' application to an adoption agency remains confidential, however.
The placement of older children can take two widely divergent paths. Generally speaking when a child has bonded to a birth parent then a need for an adoptive placement arises, it is usually critical for that child's emotional welfare to maintain ties with the birth parent. Sometimes a parent raised a child, but a problem has arisen, and parenting is no longer possible, and there are no family members able to take over the parenting role, so adoption is the best option.
In virtually all cases, the decision is up to the adoptive parents regarding how to inform the child that he or she has been adopted, and at what age to do so, if at all. Although a non-profit adoption agency (if one is used) might mail newsletters and solicit funds from the parents, traditionally, it has been extremely rare for them to communicate directly with the child (usually, adoption agencies do not contain the word "adoption" in their name).
The short answer is, yes. It was once believed that openness in adoption would undermine adoptive parents’ ability to feel entitled to parent their children, that children would be confused about the roles and rights of their adoptive parents in light of contact with their birth parents, that adoptive parents would lose all sense of control or that birth parents would not be able to successfully resolve their grief and loss in reference to their decision to place their child for adoption. What thirty-plus years of open adoption has taught us is that children are not confused about the roles of the people in their lives who love them. Adoption specialists now believe that openness can be a great gift — not just for the children — but for all who are involved in the story of adoption.
Open adoption is the exact opposite of a closed adoption. In this situation, there is some kind of fellowship between the birth and adoptive parents and the adopted child. Generally, there is an exchange of identifying information (e.g. first and last names, home address, phone number, etc.) and contact is retained between the two parties. There are several examples of an open adoption, including:
Closed adoption refers to an adoption process where there is no interaction of any kind between birth mothers and prospective adoptive families. This means that there is no identifying information provided either to the birth families or adoptive families. However, non-identifying information such as physical characteristics and medical history may be made available to those involved.
Many birth mothers do more than just meet the adoptive parents once before the birth. If they live close enough to each other it is not uncommon for the birth mother to invite the adoptive mother (or adoptive father too if the birth mother wishes) to come to her doctor appointments. This may allow all parties to the adoption a chance to bond. Adoptive parents may be present for the delivery if that is the birth mother's wish.
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.
