DETERMINATION OF APPROPRIATE REGISTRY.

(a) The administrator of the central registry shall determine the appropriate registry to which an applicant is entitled to apply.

(b) On receiving an inquiry by an adoptee, birth parent, or sibling who has provided satisfactory proof of age and identity and paid all required inquiry fees, the administrator of the central registry shall review the information on file in the central index and consult with the administrators of other registries in the state to determine the identity of any appropriate registry through which the adoptee, birth parent, or sibling may register.

(c) Each administrator shall, not later than the 30th day after the date of receiving an inquiry from the administrator of the central registry, respond in writing to the inquiry that the registrant was not placed for adoption by an agency served by that registry or that the registrant was placed for adoption by an agency served by that registry. If the registrant was placed for adoption by an agency served by the registry, the administrator shall file a report with the administrator of the central registry including:

(1) the name of the adopted child as shown in the final adoption decree;

(2) the birth date of the adopted child;

(3) the docket number of the adoption suit;

(4) the identity of the court that granted the adoption;

(5) the date of the final adoption decree;

(6) the identity of the agency, if any, through which the adopted child was placed; and

(7) the identity, address, and telephone number of the registry through which the adopted child may register as an adoptee.

(d) After completing the investigation, the administrator of the central registry shall issue an official certificate stating:

(1) the identity of the registry through which the adoptee, birth parent, or biological sibling may apply for registration, if known; or

(2) if the administrator cannot make a conclusive determination, that the adoptee, birth parent, or biological sibling is entitled to apply for registration through the central registry.
