Ohio Rev. Code § 5123.58
An agency providing protective services under contract with the department of developmental disabilities may be nominated under any of the following conditions as guardian, trustee, protector, conservator, or as trustee and protector of a person with a developmental disability:
If the results of the comprehensive evaluation required under section 5123.57 of the Revised Code indicate that the person named in the nomination is in need of protective services, the agency or service either shall reject or accept the nomination as guardian, trustee, or conservator, subject to appointment by the probate court, or reject or accept the nomination as protector, or trustee and protector.
At the time the nomination is accepted or when an appointment is made by the court, the person with a developmental disability and any person who made application for service on behalf of the person with a developmental disability under this section shall be informed by the agency, service, or court of the procedure for terminating the appointment or service. The agency or service shall cease to provide protective service as a protector pursuant to nomination under division (A), (B), or (D) of this section when a written request for termination is received by the agency from or on behalf of the person with a developmental disability. If the agency or service believes the person to be in need of protective service, the agency or service may file an application for guardianship, trusteeship, or protectorship with the probate court. Termination of any court appointment as guardian, trustee, or protector shall be by order of the probate court.
