The adult adoptee and each birth parent may voluntarily, without having been contacted by any employee or agent of the entity operating the registry, place his or her name in the appropriate registry before any disclosure or identifying information can be made. A qualified person may register by submitting a notarized affidavit to the appropriate registry stating his or her name, address and telephone number and his or her willingness to be identified solely to the other relevant persons who register. No registration may be accepted until the prospective registrant submits satisfactory proof of his or her identity in accord with the provisions specified in section 23-601 of this article. The failure of any of the three above described persons to file a notarized affidavit with the registry for any reason, including death or disability, precludes the disclosure of identifying information to those relevant persons who do register.
