In Missouri, liens filed on private property or on funds relating to a public project are known as Missouri Mechanic’s Liens. When a Missouri mechanics lien is filed with regard to work performed on privately owned property, it attaches to and encumbers the fee simple ownership of property. Contractors, as well as subcontractors, sub-subcontractors and suppliers who have a contract with a general contractor or a subcontractor can file a Missouri mechanics lien. The original contractor who contracts directly with the owner must give a disclosure notice in writing to the owner as a condition precedent to the establishment of any Missouri mechanic’s lienrights in its favor. The notice must be given either at the time of execution of the contract, when the material is delivered, when the work is commenced or with the first invoice.
