A licensed child-placing agency, children’s residential facility or independent foster home shall have the right to accept, for any purpose not contrary to the limitations contained in its license, such children as may be entrusted or committed to it by the parents, guardians, relatives or other persons having legal custody thereof, or committed by any court of competent jurisdiction. The agency, facility or home shall, within the terms of its license and the agreement or order by which such child is entrusted or committed to its care, have custody and control of every child so entrusted or committed and accepted, until he is lawfully discharged, has been adopted, or has attained his majority. An entrustment agreement for the termination of parental rights and responsibilities with respect to such child shall be executed in writing and notarized. An agency that is licensed as a child-placing agency by the Department and certified as a proprietary school for students with disabilities by the Department of Education shall not be required to take custody of any child placed in its special education program but shall enter into a placement agreement with the parents or guardian of the child concerning the respective responsibilities of the agency and the parents or guardian for the care and control of the child. Such an agency shall conform with all other legal requirements of licensed child-placing agencies including the provisions of §§ 16.1-281 and 16.1-282. A licensed private child-placing agency may accept placement of a child through an agreement with a local department where the local department retains legal custody of the child or where the parents or legal guardian of the child retain legal custody but have entered into a placement agreement with the local department or the public agency designated by the community policy and management team. Whenever a licensed child-placing agency accepts legal custody of a child, the agency shall comply with §§ 16.1-281 and 16.1-282. A children’s residential facility licensed as a temporary emergency shelter may accept a child for placement provided that verbal agreement for placement is obtained from the parents, guardians, relatives or other persons having legal custody thereof, within eight hours of the child’s arrival at the facility and provided that a written placement agreement is completed and signed by the legal guardian and the facility representative within 24 hours of the child’s arrival or by the end of the next business day after the child’s arrival.
