Civil Code §8416 — What Must Be in a California Mechanics Lien

A mechanics lien that omits required information may be void and unenforceable. California Civil Code §8416 specifies exactly what a valid lien must contain. Here is what every claimant needs to know.

Required Contents Under §8416

California Civil Code §8416 provides that a mechanics lien must state all of the following:

1. The name of the owner or reputed owner of the property, if known
2. A general statement of the kind of work furnished or the kind of materials furnished by the claimant
3. The name of the person by or to whom the labor, service, equipment, or material was furnished
4. A description of the site sufficient to identify it — legal description or street address
5. The claimant's demand, after deducting all just credits and offsets
6. A verification — a sworn statement signed under penalty of perjury

The Verification Requirement

The verification is frequently overlooked and, when missing, renders the lien defective. The verification must state that the claimant has read the lien, knows its contents, and believes the contents to be true. It must be signed by an authorized person — typically the claimant, an officer of the company, or an attorney.

Statutory Form

California provides a mandatory statutory form for mechanics liens (found in Civil Code §8416). Use of the statutory form is strongly recommended — it ensures all required elements are present and minimizes risk of a successful challenge on technical grounds.

Common Defects That Void a Lien

• Missing verification or unsigned verification
• Insufficient property description (no address, no APN, no legal description)
• Overstated amount — including amounts for work not yet performed or not covered by the contract
• Failure to identify the person who contracted with the claimant
• Wrong entity name for the claimant (e.g., DBA not properly identified)

Challenging a Defective Lien

If you are a property owner facing a lien you believe is defective, California law allows you to petition the court to expunge it. Under Civil Code §8480, you can also serve a demand requiring release of a defective lien within 10 days. See our guide to fighting a mechanics lien for the full process.
