Any person that improves real estate, whether under contract with the owner of such real estate or under contract with any agent, trustee, contractor, or subcontractor of the owner, has a lien upon the improvement and upon the land on which the improvement is situated or to which the improvement may be removed for the price or value of such contribution. Provided, however, that the amount of the lien is only for the difference between the price paid by the owner or agent and the price or value of the contribution. If the owner or agent has paid the full price or value of the contribution, no lien is allowed. Provided further that if the owner or an agent of the owner has received a waiver of lien signed by the person that improves the real estate, a lien is not allowed.
Any person that extends credit or makes a contract with any agent, trustee, contractor, or subcontractor of the owner for the improvement of real estate, upon demand, has the right to request and secure evidence of the legal description of the real estate upon which the improvement is located, including the name of the title owner of the real estate. Written notice that a lien will be claimed must be given to the owner of the real estate by certified mail at least ten days before the recording of the construction lien.
