Ohio Revised Code Title LIII. Real Property § 5309.57

Whenever any attested account to obtain a mechanic's, material supplier's, or laborer's lien is filed in the office of the county recorder by which a lien is sought to be obtained upon any registered land, the county recorder shall forthwith make notation and enter a memorial thereof upon the folium of the register where the last certificate of title to the land is registered, stating the name of the claimant, amount claimed, volume and folium of the record where recorded, and the exact time when said memorial was entered.  No lien shall attach to said land until such notation is entered by the recorder.

The recorder may, upon written application of the registered owner, cancel from any certificate of title, a mechanic's lien which has remained uncanceled for six years and one day from the date of registration of said lien, provided that no notice of any suit affecting said lien has been noted upon the register.
