I am a general contractor in ohio and have filed a mechanic's lien on the property owner. The contract I have is with his tennant and the owner states he was unaware (and very well could have been) of the project and his attorney has sent a letter asking me to voluntarily remove the lien stating that in Ohio I cannot file a lien on his property since he had no knowledge or contract for us to do the work there. Any light you can shed on this?
