Mechanic's Lien

A mechanic's lien (also called a construction lien or materialman's lien in some states) is one of the most powerful tools in a contractor's collection arsenal. If you perform work on a property and don't get paid, you can file a lien against that property. The lien attaches to the real estate itself — not to the person who hired you — which means the property can't be sold or refinanced with a clear title until the lien is resolved.

The right to file a mechanic's lien exists because of a simple principle: if your labor or materials improved someone's property, you have a right to be paid for it. The property itself serves as your collateral. This right typically extends to general contractors, subcontractors, sub-subcontractors, material suppliers, and equipment rental companies.

Every state has its own mechanic's lien laws, and the requirements vary significantly. Most require you to: (1) send a preliminary notice to the property owner within a certain number of days of starting work, (2) file the lien with the county recorder within a deadline after your last day of work (often 60-90 days), and (3) enforce the lien through a foreclosure lawsuit within a set timeframe (usually 6-12 months). Miss any of these deadlines and you lose your lien rights.

The mechanic's lien is your ultimate leverage as a contractor. The threat of a lien often motivates payment faster than anything else, because property owners can't sell or refinance with a lien on title, and lenders get nervous. Even subcontractors who have no direct contract with the property owner can lien the property — which is why owners care deeply about making sure their GC is paying the subs.

But lien rights are "use it or lose it." You must follow your state's notice and filing requirements exactly, and the deadlines are strict. Many contractors lose their lien rights simply because they didn't send the preliminary notice on time.
