Ohio Rev. Code Ann. § 2715.34

If the plaintiff proceeds against the garnishee by action, as provided in section 2715.33 of the Revised Code, for the cause that his disclosure was unsatisfactory, unless it appears on the trial that such disclosure was incomplete, the plaintiff must pay the costs thereof. When the claim of the plaintiff in attachment is satisfied, on motion, the defendant may be substituted as the plaintiff in the judgment.
