In Wisconsin, the Department of Health and Social Services maintains a centralized file for the maintenance of genetic and medical information provided by the birth parent(s). Such information is available on request in a non-identifying form to an adult adoptee (age 18), adoptive parents, the offspring of a child placed for adoption if the offspring are at least 18 years old, and an agency or social worker providing services to a child placed for adoption.

If the desired information is not in the centralized birth record file, the Department will conduct a confidential search for the birth parent(s) if the request is accompanied by a doctor's certification that the person's condition requires access to this information. Upon contacting the birth parent(s), the Department, with consent of the birth parents, will provide the requesting party with the desired genetic or medical information in a non-identifying fashion.

If the birth parent(s) consent to the release of this information the requesting party may petition the court for release. Identifying information will be provided to an adult adoptee (age 21) if both birth parents have filed with the Department or adoption agency a consent to the release of such information. Information will be released if only one parent files such consent ONLY if the other parent was not known at the time of the original adoption.

If the Department or agency does not have consents on file, the Department will [upon request] attempt to locate the birth parent(s). If they are located and consent given identifying information will be released. If they are located and consent not given, identifying information will not be released. If one known birth parent is located but not the other, information will be released.

If neither is located, information will not be released.
