Mechanics Lien Removal & Lambert Motions in California

Why owners attack the lien instead of paying

A recorded mechanics lien clouds title and pressures the owner and its lender, so a common owner response is not to pay but to try to make the lien disappear. The threat to “have the lien thrown out” is a negotiating tactic as much as a legal step — it works when the claimant is unsure whether the lien will hold up.

California gives owners several genuine ways to challenge a lien in court. Each is defensible, but only if the lien was recorded correctly, stated for the right amount, and enforced on time. Understanding the owner’s playbook is how a contractor keeps its most valuable leverage intact.

The Lambert motion

The lead tool is the Lambert motion, named for Lambert v. Superior Court (1991) 228 Cal.App.3d 383. Once a claimant has filed suit to foreclose (or the foreclosure action is stayed, for example for arbitration), the owner may bring a pretrial motion that shifts the burden onto the claimant to establish the “probable validity” of the lien. If the claimant cannot make that showing, the court can release the lien — in whole or in part — without waiting for trial.

Two points matter for a contractor. First, the question is not the ultimate merits of the underlying payment claim; it is whether the lien itself is probably valid as security pending resolution. Second, a later decision, Cal Sierra Construction, Inc. v. Comerica Bank (2012), confirmed that the Lambert motion is a remedy for property owners, not construction lenders — a useful distinction when a bank tries to use the same shortcut.

The owner’s other removal tools

Beyond the Lambert motion, owners commonly reach for three more options:

Petition to remove a lien not timely enforced — if the claimant does not file the foreclosure lawsuit within 90 days of recording, the lien expires, and the owner can petition the court to remove it and recover attorney’s fees. Missing the enforcement deadline is the single most common way a lien is lost.
Lien release bond — an owner (or contractor) may record a release bond, generally 1.5 times the lien amount, which frees the property and transfers the lien to the bond. This does not defeat the claim; it substitutes the bond for the real property as the security the claimant pursues.
Motion to expunge a defective lien — a lien that is facially defective (recorded late or early, naming the wrong owner, missing a required statutory notice, or stated in a plainly improper amount) can be expunged. The defect, not the size of the debt, is what controls.

Lambert’s real lesson: do not overstate the lien

Lambert is quoted as often for what may be liened as for the motion that bears its name. The court made clear that a mechanics lien secures the value of labor, services, and materials actually contributed to the project — not delay damages, interest, or other consequential losses, even where the contract labels them “extra work.” Those amounts may be fully recoverable in the breach of contract case, but folding them into the lien invites a removal motion and can taint the lien.

The practical takeaway is to state the lien conservatively for lienable amounts and pursue the rest through the contract and prompt-payment claims, so the lien itself is hard to attack.

Keeping a lien removal-proof

Most successful removals trace back to an avoidable error. A lien that survives an owner’s challenge usually shares the same features: a timely, valid preliminary notice; recording within the correct window; an amount limited to lienable labor and materials; the right owner and property description; the foreclosure lawsuit filed within 90 days; and contemporaneous records ready to establish probable validity if a Lambert motion comes. Getting these right at the outset is what turns the owner’s removal threat into an empty one.

Frequently asked questions

What is a Lambert motion?

It is a pretrial motion an owner brings after a foreclosure suit is filed, forcing the lien claimant to establish the lien’s “probable validity.” If the claimant cannot, the court may release the lien in whole or in part before trial. It comes from Lambert v. Superior Court (1991).

Can an owner remove my lien just by asking the court?

Not on a bare request. The owner must use a recognized procedure — a Lambert motion, a petition to remove an unenforced or expired lien, or a motion to expunge a defective lien. A properly recorded, timely, conservatively stated lien is difficult to remove.

What happens if I miss the 90-day deadline to foreclose?

The lien expires by operation of law, and the owner can petition to remove it and recover attorney’s fees as the prevailing party. This is the most common way contractors lose a lien, so the foreclosure deadline must be calendared.

If the owner posts a release bond, do I lose my claim?

No. A release bond (generally 1.5 times the lien) frees the property but transfers the lien to the bond. You pursue the bond instead of the real property; your underlying claim continues.

Can I include delay or interest damages in my lien?

Generally no. Under Lambert, a mechanics lien secures the value of labor and materials actually furnished, not delay or consequential damages. Including them can invite a removal motion — pursue those amounts through the contract claim instead. Call 949-477-9100.
