How is a Mechanic's Lien Created?  Any time a property owner hires someone to perform labor or furnish skill, material or machinery to improve the owner's real property, that person, or another person hired by that person (subcontractor), may claim a mechanic's lien against the owner's real estate to secure and enforce the payment of their bill.  It is important to understand that even subcontractors you have not directly hired can claim a mechanic's lien against your property, and they can make this claim even if you have paid your contractor.
