What Is a Mechanics Lien?
A mechanics lien (also called a construction lien or materialman's lien) is a security interest in a property created by statute. It gives contractors and suppliers a legal tool to compel payment by attaching a claim to the property itself—not just to the owner personally.
The lien attaches to the real property record at the county courthouse or recorder's office. It can prevent the property owner from selling or refinancing until the disputed amount is paid or the lien is otherwise released.
Who Can File a Mechanics Lien?

- Subcontractors of any tier

How the Lien Process Works
1. Preliminary notice — Many states require claimants to serve a preliminary notice within a set period after first furnishing work or materials. Missing this deadline can eliminate lien rights entirely.
2. File the lien — The claimant prepares and records a formal lien document at the county level within the statutory deadline after last furnishing.
3. Enforce or release — The claimant must file a lawsuit to enforce the lien before the enforcement deadline or the lien expires. Alternatively, once paid, they file a lien release.
