Mechanics Lien

A mechanics lien is the construction industry's foundational credit protection: a statutory right to encumber the improved real property itself when labor or materials furnished to a project go unpaid. It exists because construction credit runs downhill through parties who have no contract with each other — a material supplier sells to a subcontractor, who works for a general contractor, who works for the owner. The lien lets the unpaid supplier reach past its insolvent customer to the property that received the value, converting an unsecured claim against a shaky subcontractor into a secured claim against real estate.

The right is powerful but perishable, and every state's statute is different. Deadlines govern everything: many states require a preliminary notice near the start of furnishing to preserve rights at all, then a lien filing within a fixed window after last furnishing (commonly 60 to 120 days, but it varies widely), then a foreclosure suit within a further period or the lien expires. Miss any deadline and the right is gone regardless of how valid the debt is. States also differ on who qualifies (how far down the chain lien rights extend), whether residential projects carry extra requirements, and what notice the owner must receive. Public projects are generally not lienable at all — payment bonds fill that role instead.

For a credit department selling into construction, lien rights should be managed as an asset with a lifecycle: capture job information at order entry (project address, owner, GC, your customer's role), send preliminary notices systematically rather than selectively, calendar last-furnishing dates per job, and escalate well before filing windows close. The economics justify the discipline — lien-secured receivables routinely get paid because owners and lenders will not tolerate encumbered title, while unsecured claims against failed subcontractors recover little. This entry is educational, not legal advice; statutes vary by state and change, so build your notice-and-lien program with counsel or a specialized service.
