Ohio Rev. Code § 4705.03: Procedure for suspension or removal.

Before an attorney at law is suspended or removed, or publicly or privately reprimanded, written charges must be filed against him, stating distinctly the grounds of complaint, and a copy thereof, certified by the clerk, under the seal of the court, served upon him. After such service, such attorney shall be allowed a reasonable time to collect and present testimony in his own defense, and he shall be heard by himself or counsel.
