Ohio Revised Code Title XIII. Commercial Transactions § 1311.21

(A) All liens or claims for liens which may arise or accrue under sections 1311.01 to 1311.22 of the Revised Code are assignable. No such lien shall be defeated or waived by the taking by the lien claimant from any person of any promissory note or of any security for such debt other than upon the real estate itself, in the absence of a written agreement that the taking of such note or such security is a waiver of the lien.

(B) Parties entitled to liens under sections 1311.01 to 1311.22 of the Revised Code, whose claims are not due and payable, may give notice of their intention to claim a lien and may become parties to any suit to enforce a lien, or to institute such suit or proceedings themselves. Their claims shall be allowed, subject to a reduction of interest, if such claims are not due at the time of the rendition of the judgment, but no process shall issue or proceedings be had to enforce a judgment for such claim until the same matures.

(C) The rule of lis pendens does not apply to a mechanics' lien claimant whose lien rights arose or accrued before an action involving the real property which is the subject of that lien became pending pursuant to section 2703.26 of the Revised Code and whose lien is filed within the statutory period but subsequent to the date the action becomes pending pursuant to section 2703.26 of the Revised Code.
