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:

The cost for a confidential intermediary and related court fees can be around $500, but varies by state and agency. For persons who cannot afford the fees, there is usually assistance available from the tax-payer supported state department or the non-profit agency, and anyone can request from them how-to request this help. Most agencies charge a fixed fee which includes everything, and only in the most extreme and unusual circumstances ask for additional funds. If the adoptee is unable to locate (or would prefer to use a third person) to find his or her birth father, often the same confidential intermediary can be used for an additional fee.

There are also private search companies and investigators who charge fees to do a search for or assist adoptees and birth mothers and fathers locate each other, as well as to help other types of people searching. These services typically cost much more, but like search organizations and search angels, have far greater flexibility in regards to releasing information, and typically provide their own intermediary services. However, they may not circumvent the law regarding the confidentiality process.

Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
