Ohio Revised Code Title XXI. Courts Probate Juvenile § 2135.08

(A) The proxy under a declaration is not, as a result of acting in that capacity, personally liable for the cost of treatment provided to the declarant. Except to the extent the right is limited by the declaration or any federal law, a proxy has the same right as the declarant to receive information regarding the proposed mental health treatment of the declarant and to receive, review, and consent to disclosure of the declarant's medical records relating to that treatment. This right of access does not waive any evidentiary privilege.

(B) In exercising authority under a declaration, the proxy has a duty to act consistently with the desires of the declarant as expressed in the declaration. If the declarant's desires are not expressed in the declaration, the proxy has a duty to act in what the proxy in good faith believes to be the best interests of the declarant.

(C) A proxy is not subject to criminal prosecution, tort or other civil liability for injury, death, or loss to person or property, or professional disciplinary action for an action taken in good faith under a declaration for mental health treatment.
