Ohio Revised Code Title LIII. Real Property § 5303.04

In an action for the recovery of real property, it is sufficient if in his answer the defendant denies generally the title alleged in the petition, or that he withholds the possession. If he denies the title only, possession by him shall be taken as admitted. When he does not defend for the whole premises, the answer shall describe the particular part for which defense is made. The defendant also may set forth in his answer other grounds of defense and counterclaim, as in any other form of action.
