Lien Law

Lien

In Plain English

A legal claim against property that someone uses to force payment for work or materials.

Definition

A lien is a legal right or claim against property as security for the payment of a debt or obligation. In construction, liens arise by statute and allow contractors and suppliers to encumber the property they improved when payment is not received. A lien must be perfected through specific filing and notice procedures and can ultimately be enforced through a foreclosure action that forces the sale of the property to satisfy the debt.

Why It Matters in Bidding

Lien rights are the primary leverage subcontractors and suppliers hold to secure payment, so they directly shape how procurement, payment terms, and risk are negotiated on a project. Owners and general contractors track lien deadlines and preliminary notices closely because an unresolved lien can cloud title, block financing draws, and stall project closeout.

Example

When the framing subcontractor went 60 days unpaid, it preserved its rights by filing a mechanic's lien against the property before the statutory deadline, forcing the owner to address the dispute before refinancing.

Frequently Asked Questions

Lien rights are created by statute and vary by state. A claimant typically must serve a preliminary or pre-lien notice, then record the lien within a strict deadline tied to last work or project completion. To collect, the claimant files a foreclosure action within another deadline, potentially forcing a court-ordered sale of the property.
A lien is the claim itself, encumbering the property as security for unpaid work. A lien waiver is a signed document in which a contractor or supplier gives up that claim, usually in exchange for payment. Owners collect waivers with each progress payment specifically to keep title clear of potential liens.
In many states, yes. Mechanic's lien rights generally attach to the improved property, not to the chain of payments. If the GC was paid but failed to pay a subcontractor or supplier, that party may still lien the property. This double-payment exposure is why owners require lien waivers throughout the project.
