we have a subcontractor that has walked off of the job before his job was completed, we have paid him for what work he has done, does he have the right to file a lien on the balance as if he completed his job?
The question should be – if the subcontractor files a lien is it enforceable? Based upon the facts you set out – the answer
is, no. If the facts might not be accurate or complete you should consult an attorney.
