Ohio Rev. Code § 5123.93
Minors with intellectual disabilities shall remain under the guardianship of their parents or of a guardian appointed pursuant to Chapter 2111. of the Revised Code, notwithstanding institutionalization pursuant to any section of this chapter, unless parental rights have been terminated pursuant to a court finding that the child is neglected, abused, or dependent pursuant to Chapter 2151. of the Revised Code. If a minor with an intellectual disability has been found to be dependent, abused, or neglected, the public children services agency to whom permanent custody has been assigned pursuant to Chapter 2151. of the Revised Code shall have the same authority and responsibility it would have if the child were not a person with an intellectual disability and were not institutionalized. In no case shall the guardianship of a person with an intellectual disability be assigned to the managing officer or any other employee of an institution in which the person is institutionalized, or be assigned, unless there is a relationship by blood or marriage or unless the service is a protective service as defined in section 5123.55 of the Revised Code, to a person or agency who provides services to the person with an intellectual disability.
