Before providing shelter and supportive services to an unaccompanied minor in need of shelter, a service provider shall: register with the Department; develop and implement a procedure to screen each staff member who works with minors, including through a State and national criminal history records check or a private agency background check conducted in accordance with § 4–2708 of this subtitle; and obtain written consent from the unaccompanied minor in need of shelter. The written consent from the unaccompanied minor in need of shelter shall state the minor’s: age; guardianship status, if known; and living situation. A service provider may not provide shelter to a minor if the service provider has knowledge that the minor: knowingly provided false information in the written consent required under subsection (a) of this section; or does not meet the definition of an unaccompanied minor in need of shelter under this subtitle.
