Let’s begin with the question: What is a mechanics lien? Mechanic's liens are legal devices by which contractors, subcontractors, laborers, suppliers, or even some design professionals can secure unpaid amounts by placing encumbrances on a property for the work done or materials supplied. The Constitution of California recognizes the right to the lien in favor of the party who may enforce payment according to statute.
Upon filing a mechanic's lien, it is placed on record against the property's title, thereby having a public record that could go against refinancing or sale of the property until the claim is settled. Property owners see it as a major encumbrance that must be addressed before the property can be sold or refinanced.
Who Can File a Mechanics Lien in California?
In California, certain workers and parties may file mechanics' liens if unpaid, including: general contractors, subcontractors, laborers, material and equipment suppliers, and certain design professionals such as architects and engineers.
The work or materials must directly contribute to the improvement of the real property. Generally, non-permanent or non-improving items are not valid and would not qualify for a lien.
Why File a Mechanic's Lien in California?
A mechanics' lien:
-
Creates a secured interest for payment by placing a lien on the property.
-
Causes a sense of urgency for the property owner because, as long as the lien is present, the property cannot be cleared or transferred in title.
-
Can be foreclosed upon as a means of enforcing payment, when necessary.
How to file a mechanics lien in California
Follow these five essential steps carefully to file a mechanics' lien and ensure your lien is valid and enforceable:
1. Send the Preliminary 20-Day Notice
Claimants must serve a preliminary notice within 20 days of the initial labor or material delivery. This requirement applies to all claimants who began work or delivered materials after those 20 days because they must notify the property owner, general contractor, and lender of the work's completion, which safeguards all lien rights.
Any delay in sending the above-mentioned notice results in the forfeiture of rights for amounts accrued before the notice was given.
2. Prepare the Mechanics' Lien Claim
A Lien Claim, which is a "Claim of Mechanics' Lien," must be in writing, signed, and verified. A claimant must include the following:
-
Name of the owner or reputed owner
-
Description of the labor or materials supplied
-
Name of the party who engaged or benefited from the work
-
Description of the property (address or parcel number)
-
Contact information of the claimant
-
Proof of service affidavit stating the date, means, and party served with the notice
-
In compliance with Civil Code $\S 8416$, a notice with a statutory warning statement typed or printed in bold
3. Serve the Claim and Proof of Service Affidavit
Exceptions in service may apply to the lender or contractor (if they cannot serve the owner). Service may be by registered mail, certified mail, or first-class mail, provided the post office retains evidence.
4. Enforcement of the Foreclosure Must Begin Within 90 Days
Foreclosure must be commenced within 90 days after the lien has been recorded, and a Notice of Lis Pendens must be filed to assert your claim.
