A mechanics lien is the strongest collection tool in California construction, and the easiest to lose. It secures payment against the property itself rather than against whoever failed to pay, which is why it works even when a general contractor is insolvent. It also runs on deadlines measured in days, and a claimant who misses one loses the lien permanently regardless of how much is owed. Bay Legal, P.C. records and enforces liens for contractors, subcontractors, and suppliers, and removes invalid ones for property owners.
Definition: A mechanics lien is a recorded claim against real property securing payment for labour, services, equipment, or materials that improved it.
Thanks so much for all the support on my case.
This review reflects one client’s experience. Results depend on the facts and law of each individual case and do not guarantee or predict a similar outcome in your matter.
Who can record a mechanics lien in California?
Anyone who furnished labour, services, equipment, or materials for a work of improvement. The right is constitutional as well as statutory — it sits in Article XIV, section 3 of the California Constitution, which is why courts construe the remedial provisions liberally while enforcing the procedural ones strictly. The operative statutes run from Civil Code section 8400 onward.
Contractors, subcontractors, material suppliers, equipment lessors, and design professionals all qualify. The threshold requirement is not the contract but the contribution: the work or materials must have gone into improving that specific property.
One prerequisite ends more claims than any other. A claimant without a direct contract with the owner must serve preliminary notice under Civil Code section 8200, generally within 20 days of first furnishing labour or materials. Serve it late and lien rights are limited to the 20 days preceding service. Never serve it and, for most claimants, there are no lien rights at all.
What are the mechanics lien deadlines?
Three, and each one ends the right if missed. The recording deadline differs depending on whether you contracted directly with the owner.
| Step | Deadline | Authority |
|---|---|---|
| Serve preliminary notice | 20 days from first furnishing labour or materials | Civ. Code § 8200 |
| Record the lien — direct contractor | Earlier of 90 days after completion, or 60 days after a notice of completion or cessation is recorded | Civ. Code § 8412 |
| Record the lien — all other claimants | Earlier of 90 days after completion, or 30 days after a notice of completion or cessation is recorded | Civ. Code § 8414 |
| Serve the recorded lien on the owner | Within 20 days of recording | Civ. Code § 8416 |
| File suit to enforce the lien | 90 days after recording | Civ. Code § 8460 |
Two consequences worth stating plainly. Failure to serve the recorded lien on the owner within 20 days under section 8416 is itself a ground on which the lien can be invalidated, not merely a procedural irregularity. And a lien not enforced by suit within 90 days under section 8460 expires by operation of law — though it will keep appearing in the property records until it is formally released, which is the problem the next section addresses.
What must the lien contain?
A recorded lien must state the claimant’s name, the amount actually owed, the name of the owner or reputed owner, and a description of the property sufficient to identify it. It must be verified, and it must be accompanied by the statutorily prescribed Notice of Mechanics Lien addressed to the owner.
Overstating the amount is a genuine risk rather than a negotiating tactic. A lien claiming substantially more than is owed can be attacked as wilfully exaggerated, which can invalidate it and expose the claimant to liability. Claim what is owed.
How does a property owner remove a mechanics lien?
Six routes, roughly in order of speed and cost.
- Payment and release. The amount is paid and the claimant records a release with the county recorder. Fastest where the debt is genuinely owed.
- Negotiated release. A settled figure in exchange for a recorded release. Frequently cheaper than the litigation it avoids.
- Expiry. A lien not enforced within 90 days of recording expires on its own. It remains visible in the records until formally removed, so expiry alone does not clear title.
- Written demand. A demand to the claimant to record a release. The claimant is allowed a period to respond, and the demand is a prerequisite to the petition route below.
- Petition to release. Where the claimant will not release an expired or invalid lien, a petition may be filed under Civil Code section 8480. It is an expedited procedure, and the prevailing party may recover reasonable attorney fees under section 8488 — which is unusual and makes the route more attractive than it first looks.
- Bonding off. A surety bond of 125 percent of the lien amount under Civil Code section 8424 releases the property from the lien while the underlying dispute continues against the bond. The route to take when a sale or refinance cannot wait for the merits.
Which one fits depends on whether the debt is owed, whether the lien is procedurally valid, and how quickly the title must be cleared. An owner facing a closing in three weeks has different priorities from one with time to litigate.
What if the lien is invalid?
An invalid lien is not merely unenforceable — recording one can itself be actionable. A lien recorded without a basis, or maintained after it has expired, may support a claim for slander of title, since it clouds the record and impairs the property’s marketability. That is the practical leverage behind a demand for release.
Common grounds for invalidity: no preliminary notice where one was required, recording outside the statutory window, failure to serve the recorded lien on the owner within 20 days, expiry through failure to bring an enforcement action within 90 days, a wilfully exaggerated amount, and work that does not qualify as an improvement to that property.

Frequently Asked Questions
Who can record a mechanics lien in California?
Anyone who furnished labour, services, equipment, or materials improving the property — contractors, subcontractors, suppliers, equipment lessors, and design professionals. The right is grounded in Article XIV, section 3 of the California Constitution. A claimant without a direct contract with the owner must first have served preliminary notice under Civil Code section 8200.
How long do I have to record a mechanics lien?
A direct contractor must record within the earlier of 90 days after completion of the work of improvement or 60 days after a notice of completion is recorded. Every other claimant must record within the earlier of 90 days after completion or 30 days after a notice of completion. Missing the window ends the lien right permanently.
What happens after I record the lien?
Two further deadlines. The recorded lien must be served on the owner within 20 days under Civil Code section 8416, and failure to do so is a ground for invalidating it. Suit to enforce must then be filed within 90 days of recording under section 8460. A lien not enforced in that window expires by operation of law.
How do I get a mechanics lien off my property?
By payment and recorded release, by negotiated settlement, by written demand where the lien has expired, by petition to release under Civil Code section 8480 if the claimant refuses, or by bonding around it with a surety bond at 125 percent of the claim under section 8424. Bonding off is the route when a sale or refinance cannot wait.
Can I recover attorney fees for removing an invalid lien?
Potentially. On a petition to release under Civil Code section 8480, the prevailing party may be awarded reasonable attorney fees under section 8488. That fee provision is unusual in California practice and makes the petition route more attractive than the cost of a motion would otherwise suggest.
What if the lien claims more than I owe?
A wilfully exaggerated lien can be invalidated and can expose the claimant to liability, so an inflated amount is a risk to the claimant rather than leverage. If a lien on your property overstates the debt, that overstatement is itself a ground to challenge it.
Related Questions
What is a preliminary 20-day notice?
A notice served early in a project that preserves lien, stop payment notice, and payment bond rights for claimants without a direct contract with the owner. It is the cheapest document in construction and its absence ends more otherwise valid claims than anything else.
Does a mechanics lien stop me selling my property?
In practice, usually. A recorded lien clouds title, and most buyers and lenders will not proceed until it is released or bonded around. That is precisely why the remedy has the leverage it does.
Can an unlicensed contractor record a lien?
No. Business and Professions Code section 7031(c) makes any security interest taken to secure payment for unlicensed work unenforceable, and that includes a mechanics lien.
What is a notice of completion, and why does it matter to me?
A document the owner records when the work of improvement is finished. Recording it shortens the lien window sharply — to 60 days for a direct contractor and 30 days for everyone else — which is why owners record one and why claimants must watch for it.
Is a mechanics lien the same as a stop payment notice?
No. A lien attaches to the property; a stop payment notice freezes construction funds held by the owner or lender. They are separate remedies with separate procedures and may be pursued at the same time.
