Mechanic's Lien
A lien filed by a contractor, subcontractor, or supplier who provided labor or materials to improve a property but wasn't paid — securing their claim against the property itself.
A mechanic's lien (also called a construction lien or materialman's lien) is a lien that contractors, subcontractors, laborers, and material suppliers can record against a property when they have furnished work or materials to improve it and have not been paid. The lien attaches to the improved property, giving the unpaid party security and, ultimately, the ability to force a sale to collect. Mechanic's liens are a distinctive type of encumbrance because, in many states, they can claim priority dating back to when the work began or materials were first furnished — even ahead of a later-recorded mortgage. That makes them an important item in evaluating a mortgage note's collateral.
How a mechanic's lien works
The process is governed by detailed, deadline-driven state statutes, but generally:
- A contractor or supplier provides labor or materials to improve real property.
- They go unpaid and (in many states) send a required preliminary notice.
- They record a mechanic's lien within a statutory deadline after completing work or last furnishing materials.
- If still unpaid, they must file to foreclose the lien within another deadline, or the lien expires.
Missing any statutory deadline can invalidate the lien — which is why both claimants and title professionals watch these dates closely.
The priority twist
Unlike most liens, which take priority strictly by recording date, mechanic's liens in many states relate back to the commencement of the work or the first delivery of materials. A mechanic's lien recorded after a mortgage can therefore sometimes prime that mortgage if the work began earlier. This "relation-back" feature is a key risk for lenders and note buyers and a major reason title companies require lien waivers and may hold back funds during construction.
Why mechanic's liens matter when you buy or sell a note
For a note buyer, a mechanic's lien on the collateral is a red flag that warrants close attention during due diligence:
- Possible super-priority: Because of relation-back rules, a mechanic's lien could outrank the note's lien, threatening the holder's first-lien position and the equity protecting the note.
- Signals a dispute: A recorded mechanic's lien often indicates an unresolved payment dispute or recent construction, both of which add uncertainty.
- Cure before closing: Such liens may need to be paid, bonded around, or released (with lien waivers) before a note sale can close cleanly.
For a note seller, ensuring no unexpected mechanic's liens cloud the collateral — and obtaining lien waivers when work has been done — protects the sale price and avoids last-minute surprises. A title search and title insurance help identify and manage this risk.
Example
A note buyer is reviewing a $200,000 first-lien note on a recently renovated home. The title search turns up a $25,000 mechanic's lien filed by a contractor whose work predates the recording of the note's deed of trust. Because of the state's relation-back rule, that lien may take priority over the note. The buyer requires the lien to be paid and released before closing, protecting the note's first-lien position.
