Ohio Revised Code Title XXIX. Crimes Procedure § 2941.149

(A) The determination by a court that an offender is a repeat violent offender is precluded unless the indictment, count in the indictment, or information charging the offender specifies that the offender is a repeat violent offender. The specification shall be stated at the end of the body of the indictment, count, or information, and shall be stated in substantially the following form:

“SPECIFICATION (or, SPECIFICATION TO THE FIRST COUNT). The Grand Jurors (or insert the person's or prosecuting attorney's name when appropriate) further find and specify that (set forth that the offender is a repeat violent offender).”

(B) The court shall determine the issue of whether an offender is a repeat violent offender.

(C) At the arraignment of the defendant or as soon thereafter as is practicable, the prosecuting attorney may give notice to the defendant of the prosecuting attorney's intention to use a certified copy of the entry of judgment of a prior conviction as proof of that prior conviction. The defendant must then give notice to the prosecuting attorney of the defendant's intention to object to the use of the entry of judgment. If the defendant pursuant to Criminal Rule 12 does not give notice of that intention to the prosecuting attorney before trial, the defendant waives the objection to the use of an entry of judgment as proof of the defendant's prior conviction, as shown on the entry of judgment.

(D) As used in this section, “repeat violent offender” has the same meaning as in section 2929.01 of the Revised Code.
