Mechanics Liens on California Property
By Josué Cristóbal Guerrero, Founding Partner · Published

In short
A mechanics lien is a recorded claim securing payment for work on a property, available under Civil Code sections 8000 and following to contractors, subcontractors, suppliers, equipment lessors, laborers and design professionals. It clouds title until released or removed, and the way you respond matters, because suing over the act of recording can trigger the anti-SLAPP statute.
Who can record one
Civil Code section 8400 sits within Part 6 of the Civil Code, Works of Improvement, at sections 8000 and following. It gives lien rights to a person who provides work authorized for a work of improvement, and lists direct contractors, subcontractors, material suppliers, equipment lessors, laborers and design professionals.
The breadth surprises owners. A subcontractor or supplier you never hired, and may never have heard of, can record against your property if they supplied the job and were not paid by the contractor who was.
That is the risk the preliminary notice system exists to surface, and it is why paying a general contractor is not by itself proof that everyone below them was paid.
What it does to you
The lien is recorded against the parcel. It appears on the title report, it clouds title, and it will generally stop a sale or a refinance until it is resolved. That leverage is the point of the mechanism.
It applies whether or not the underlying claim is well founded. A disputed lien and a valid lien look identical to a title company.
The routes to removing it
Pay or settle the underlying claim and obtain a release. Fastest where the amount is small or the claim is good.
Wait for it to lapse. A lien is time limited: the claimant must commence an action to enforce it within the statutory period, and a lien not enforced in time can be removed. Deadlines here are short and specific, so this depends on knowing the exact dates.
Petition to release it where it is invalid on its face or has expired. There is a statutory procedure for this.
Post a bond to release the property, which substitutes the bond for the land and lets a transaction proceed while the dispute continues.
Why suing over the recording is risky
The instinct on receiving a lien you regard as bogus is to sue the person who recorded it. That is where owners run into Code of Civil Procedure section 425.16.
The anti-SLAPP statute provides a special motion to strike claims arising from protected petitioning activity, and the Legislature directed that it be construed broadly. Recording a lien and pursuing it can fall within that protection, because it is a step toward and connected with a judicial proceeding.
The mechanics of the statute make the risk concrete. The defendant must show the claim arises from protected activity, then the burden shifts to the plaintiff to establish a probability of prevailing. A defendant who succeeds recovers attorney fees and costs.
So an owner who responds to an unjustified lien by suing over the act of recording can find themselves paying the lien claimant's legal fees. The safer route is almost always to attack the lien through the lien procedures, not to attack the person for having recorded it.
Checking whether the lien is even valid
Before deciding how to respond, establish whether the lien is good. Several requirements have to be met and a failure on any of them affects enforceability.
Whether the claimant gave a preliminary notice where one was required. Many claimants below the direct contractor must serve one to preserve lien rights.
Whether the lien was recorded within the applicable period, which depends on the claimant's role and on whether a notice of completion or cessation was recorded.
Whether the claimed amount corresponds to work actually provided, since a lien substantially overstated can be challenged.
Whether an action to enforce was commenced within the statutory period. A lien not enforced in time can be removed, and this is the most common route by which they resolve without payment.
Whether the property description and the claimant's details are correct.
Why the anti-SLAPP risk is real
Code of Civil Procedure section 425.16 gives a special motion to strike claims arising from protected petitioning activity, and the Legislature directed that the statute be construed broadly.
Recording a mechanics lien and pursuing it is connected with an anticipated judicial proceeding, so a claim aimed at the act of recording can fall inside that protection.
The consequences are asymmetric. The defendant shows the claim arises from protected activity; the burden then shifts to you to establish a probability of prevailing. A defendant who succeeds recovers attorney fees and costs. An owner who sued out of frustration ends up funding the lien claimant's lawyers.
The safer route is to use the lien procedures themselves: dispute the amount, wait out the enforcement period, petition to release an expired or facially invalid lien, or bond around it. Those routes attack the lien rather than the act of recording.
Preventing them on your next project
Track the preliminary notices you receive. Each one tells you who is on the job and who could lien, which is information you only get if you keep them.
Use joint checks or conditional releases so that payment to the direct contractor is tied to the people below being paid.
Obtain lien releases as you go, conditional on payment and then unconditional once funds clear, rather than at the end.
Consider a payment bond on larger work.
The common thread is that paying your contractor is not by itself proof that the people who supplied the job were paid, and the lien system puts that risk on the owner.
