a) For purposes of this Section, “post-adoption reunion services” means services provided by the Department to facilitate contact between adoptees and their siblings when one or more is still in the Department’s care or adopted elsewhere, with the notarized consent of the adoptive parents of a minor child, when such contact has been established to be necessary to the adoptee’s best interests and when all involved parties, including the adoptive parent of a child under 21 years of age, have provided written consent for such contact.
     (b) The Department shall provide to all adoptive parents of children receiving monthly adoption assistance under subsection (j) of Section 5 of this Act a notice that includes a description of the Department’s post-adoption reunion services and an explanation of how to access those services. The notice to adoptive parents shall be provided at least once per year until such time as the adoption assistance payments cease.
     The Department shall also provide to all youth in care, within 30 days after their 18th birthday, the notice described in this Section.
     (c) The Department shall adopt a rule regarding the provision of search and reunion services to youth in care and former youth in care.
