Ohio Crim. R. 12.1
As amended through March 13, 2024
Whenever a defendant in a criminal case proposes to offer testimony to establish an alibi on his behalf, the defendant shall, not less than thirty days before trial in a felony case and fourteen days before trial in a misdemeanor case, file and serve upon the prosecuting attorney a notice in writing of the defendant's intention to claim alibi. The notice shall include specific information as to the place at which the defendant claims to have been at the time of the alleged offense. If the defendant fails to file such written notice, the court may exclude evidence offered by the defendant for the purpose of proving such alibi, unless the court determines that in the interest of justice such evidence should be admitted.
