Received a Notice of Right to Lien from a subcontractor that has been hired by the "Customer" the General Contractor to supply material on a commercial property. Possibly supply labor too. The General Contractor has been hired by the Tenant, the Tenant per the lease has agreed that it shall get the Landlord's review and approval for all contractors that will be performing to the improvements of the Premises. The Tenant will not allow for any liens to be attached to the premises. At this time the Tenant has not submitted the contractor's name that we received the Notice to Lien for approval or for review as the lease states. In addition, the material that the subcontractor has listed in the Notice of Right to Lien is not an item mentioned as an improvement of the space. I'd like to know besides the posting of a non-responsibility, If I should take this a step further and send a letter in response to this notice to all three parties, (1) Tenant (2) General Contractor (3) the Subcontractor that provided the notice. The notice would state the non-responsibility and the agreed-upon terms of the lease.
