CSLB Law & Business ExamInsurance and LiensMedium
A subcontractor's office manager prepares a 20-day preliminary notice and simply drops it in a regular first-class mailbox addressed to the property owner and general contractor. Under California mechanics lien law, what is the legal effect of this method of service?
- AThe notice is invalid because preliminary notices must always be served by personal delivery to the owner
- BThe notice is invalid because preliminary notices must be served by certified or registered mail, or express service
- CThe notice is valid because any form of mail delivery satisfies the statutory requirement
- DThe notice is valid only if the recipients later acknowledge receiving it in writing
Show answer & explanationAnswer & explanation
Correct answer: B. The notice is invalid because preliminary notices must be served by certified or registered mail, or express service
California Civil Code requires preliminary 20-day notices to be served by certified or registered mail (return receipt requested), or by an express service carrier that provides proof of service, or by personal delivery. Ordinary first-class mail does not satisfy the statute even if the notice actually reaches the recipient.
Why the other options are wrong
- A. Personal delivery is one acceptable method but not the exclusive required method.
- C. Ordinary first-class mail alone does not meet the statutory service requirement.
- D. Acknowledgment of receipt is not a substitute for proper statutory service method.
Preliminary Notice Service Method
California law requires the 20-day preliminary notice to be served by certified/registered mail, express service, or personal delivery — not ordinary mail.
- First-class mail alone is insufficient
- Certified/registered mail with return receipt is the common method
- Proof of proper service is essential to preserve lien rights
Memory trick: Certified, not just stamped — proof is required
