Ohio Rev. Code § 2715.044
An order of attachment issued by a court shall not be effective until the plaintiff that filed the motion for attachment files with the court a bond to the defendant against whom the motion was filed, executed by the plaintiff's surety, in an amount twice the approximate value of the property to be attached under the order, to the effect that, should judgment be issued against the plaintiff, the plaintiff will return the property taken or pay the value so assessed, at the election of the defendant, and also pay the damages suffered by the defendant as a result of the taking and detention of, and any injury to, the property and the costs of the action. If the plaintiff does not know the approximate value of the property sought to be attached under the order, or if the identity of the property to be attached is not known, the bond shall be in an amount twice that of the plaintiff's claim, as indicated in the plaintiff's affidavit filed pursuant to section 2715.03 of the Revised Code.
In lieu of the bond, the plaintiff may deposit with the clerk of the court cash in an amount equal to twice the approximate value of the property or, if that value is not known or the identity of the property to be attached is not known, equal to twice the amount of the claim of the plaintiff.
When the ground of attachment is that the defendant is a foreign corporation, or not a resident of this state, the order of attachment may be issued without a bond.
If the plaintiff is indigent, the court may, on motion of the plaintiff or on its own motion, waive the bond required by this section or may set the bond in a lower amount, as fairness requires.
