(A) When the department determines that a child is eligible for supplemental benefits, a written agreement must be executed between the parents and the department.

(B) In individual cases supplemental benefits may begin with the adoptive placement or at the appropriate time after the adoption decree and will vary with the needs of the child as well as the availability of other resources to meet the child’s needs.

(C) The supplemental benefits may be for special services only, or for money payments, and either for a limited period, for a long term, or for a combination of them. The amount of time-limited, long-term supplemental benefits may not exceed that which currently would be allowable for the child under foster family care or, in the case of a special service, the reasonable fee for the service rendered.

(D) When supplemental benefits last for more than one year the adoptive parents shall certify that the child remains under the parents’ care and that the child’s need for supplemental benefits continues. Based on the certification and investigation by the agency and available funds, the agency may approve continued supplemental benefits. These benefits may be extended so long as the continuing need of the child is verified and the child is the legal dependent of the adoptive parents.

(E) A child who is certified as eligible for supplemental benefits remains eligible and shall receive supplemental benefits, if necessary for adoption, regardless of the domicile or residence of the adopting parents at the time of application for adoption, placement, legal decree of adoption, or after adoption.
