What is a mechanic's lien?

A mechanic's lien is a security interest attached to a specific piece of real property. When a contractor, subcontractor, or supplier is not paid for work or materials they provided to that property, they can file a lien that becomes part of the public record on the title. The lien creates a cloud on ownership: the property cannot be sold or refinanced without addressing the outstanding claim, which is the practical leverage that motivates payment.

The filing process is highly state-specific. Most states require the claimant to serve a preliminary notice early in the project, then file the lien within a fixed window after the last day of work — typically 60 to 120 days, though the exact deadline varies. Missing any step, including the preliminary notice, can permanently waive the lien right even on a legitimately unpaid balance. Lien rights are one of the few collection tools that expire automatically if not used on time.

This page is general information, not legal advice. Mechanic's lien law varies significantly by state, project type, and the claimant's position in the payment chain. Before filing a lien or relying on lien rights to resolve a disputed balance, consult a qualified attorney in the state where the project is located.
