n. the right of a craftsman, laborer, supplier, architect or other person who has worked upon improvements or delivered materials to a particular parcel of real estate (either as an employee of the owner or as a sub-contractor to a general contractor) to place a lien on that real property for the value of the services and/or materials if not paid. Numerous other technical laws surround mechanic's liens, including requirements of prompt written notice to the owner of the property (even before the general contractor has been tardy in making payment), limits on the amount collectable in some states, and various time limitations to enforce the lien. Ultimate, last-resort enforcement of the mechanic's lien is accomplished by filing a lawsuit to foreclose the lien and have the property sold in order to be paid. Property owners should make sure that their general contractors pay their employees or subcontractors to avoid a mechanic's lien, since the owner could be forced to pay the debts of a general contractor even though the owner has already paid the contractor. If the worker or supplier does not sue to enforce the mechanic's lien, he/she may still sue for the debt.
