What Is a Mechanic's Lien?

A mechanic's lien is a statutory, nonconsensual lien placed on real property by a person who supplied labor, materials, or services to improve that property and has not been paid. The lien gives the claimant a security interest in the real estate itself, which means the claimant may eventually force a sale to collect. Mechanic's liens are creatures of statute, so the requirements are strict and vary from state to state. For paralegals, they are a classic area where a missed deadline can destroy a client's rights, which is exactly why they show up on certification exams.

Who Can File a Mechanic's Lien?

Eligible claimants usually include:

General contractors who contract directly with the owner.
Subcontractors who contract with the general contractor.
Material suppliers who deliver goods used in the improvement.
Laborers, equipment lessors, architects, engineers, and surveyors in many states.

The person who deals directly with the owner is often called the original or prime contractor. Everyone below that tier is a subcontractor or supplier. Many states limit how far down the chain a lien right extends, and sub-subcontractors or lower tier suppliers often must give additional notices to preserve rights.

What Are the Steps to Perfect a Mechanic's Lien?

While specifics differ, the process generally follows this path:

Preliminary notice. Many states require subcontractors and suppliers to send a notice to the owner and general contractor within a set period after first furnishing labor or materials. Failure to send it can bar the lien.
Performance of work. The claimant furnishes labor or materials under a contract, whether written or oral.
Nonpayment. The claimant is not paid the amount due.
Preparing the lien claim. The paralegal drafts the notice or claim of lien, which typically includes the claimant's name and address, the owner's name, a legal description of the property, a description of the work, the amount owed, and the dates of first and last furnishing. Many states require verification or notarization.
Recording. The claim is filed in the county land records where the property is located, within the statutory deadline. Recording gives constructive notice to the world.
Serving the owner. Many states require a copy of the recorded lien to be served on the owner, sometimes within a short period after recording.
Foreclosure. If the debt remains unpaid, the claimant must file suit to enforce the lien within the statute of limitations, often between six months and two years after recording. If suit is not timely filed, the lien expires.

What Is Lien Priority?

Priority determines who gets paid first from sale proceeds. Most states follow a first-in-time rule for ordinary liens, but mechanic's liens are often treated differently. In many jurisdictions the lien relates back to the date work began or the date the first materials were delivered, which can give it priority over a mortgage recorded after commencement of work, even though the lien itself was recorded later. Other states use the recording date. Purchase money mortgages and construction loans often have special rules. This is a common exam topic, so remember the idea of relation back and always check the local statute.

What Defenses Can an Owner Raise?

An owner or general contractor challenging a lien may argue:

The claimant failed to give required preliminary notice.
The lien was filed late or foreclosure suit was not timely commenced.
The work was defective or the contract was not fully performed.
The amount claimed is overstated, since a knowingly overstated lien can be invalid and may expose the claimant to liability.
The owner already paid the general contractor and the state follows a rule limiting subcontractor recovery to the unpaid balance owed by the owner.
The claimant signed a valid lien waiver.

What Are Lien Waivers?

A lien waiver is a document in which a claimant gives up lien rights in exchange for payment. Waivers come in four common forms: conditional progress, unconditional progress, conditional final, and unconditional final. A conditional waiver is effective only when payment actually clears. An unconditional waiver takes effect upon signing, so a claimant should never sign one before funds are received. Owners and lenders routinely require waivers with each draw to protect against double payment, and paralegals frequently track them.

How Can an Owner Remove a Lien?

Options include paying the claim, negotiating a release, recording a lien bond (also called bonding around the lien) so that the claim attaches to the bond instead of the property, or successfully challenging the lien in court. Once resolved, a release or satisfaction of lien should be recorded to clear title. A title company will not insure over an unreleased lien.

Mechanic's Liens and Public Projects

Public property generally cannot be subject to a lien because of sovereign immunity. Instead, contractors on public works typically rely on payment bonds, such as those required under the federal Miller Act or state "little Miller Acts." Claimants on these projects must follow bond claim notice and suit deadlines rather than lien procedures.

Practical Tips for Paralegals

Build a deadline calendar the moment a lien matter opens. Confirm the correct legal description from the deed, not from a street address. Verify the last date of furnishing from project records. Keep proof of service and recording. And always review the state statute, since even small variations in wording can invalidate a claim.
