(a)

(1) A mutual consent voluntary adoption registry may be established and maintained by any licensed voluntary agency involved in an adoption.

(2) Persons eligible to receive identifying information shall work through the agency involved in the adoption. If that agency has merged or ceased operations, a successor agency may assume possession of the files for the purpose of establishing, maintaining, and operating the mutual consent voluntary adoption registry concerning those adoptions.

(3) Any licensed voluntary agency may delegate or otherwise contract with another licensed voluntary agency with expertise in post-legal adoption services to establish, maintain, and operate the registry for the delegating agency.

(4) If any agency ceasing to operate does not transfer adoption records to another licensed agency, it shall provide all records required to be maintained by law to the Department of Human Services.

(b) The department shall establish and maintain a mutual consent voluntary adoption registry for all adoptions arranged by the department or may contract out the function of establishing and maintaining the registry to a licensed voluntary agency with expertise in providing postlegal adoption services, in which case the agency shall establish and maintain the registry that would otherwise be operated by the department.

(c) The department shall keep records of every adult adoptee and birth parent reunited through the use of the mutual consent voluntary adoption registry.
