Ohio Rev. Code Ann. § 2151.411

Whenever a child comes into the custody of a public children services agency, either as part of a sibling group or subsequent to the previous placement of a sibling, the agency is strongly encouraged to make reasonable efforts to place the siblings together, unless it would be contrary to the siblings' best interest or well-being. If siblings are not placed together, the agency should make reasonable efforts to ensure the siblings maintain frequent connections through visitation or other ongoing interaction, unless contrary to the siblings' placement or well-being.
