When you're working on a public project in California and haven't been paid, you can't file a mechanic's lien like you would on private property. Instead, California's Little Miller Act gives you the right to make a claim against the payment bond that was required for the project. This law ensures that contractors, subcontractors, and suppliers have a way to collect payment even when the government entity can't have liens placed against its property.
Many California contractors don't realize they have these bond claim rights, or they miss critical deadlines because they don't understand the process. The Little Miller Act has strict timing requirements and specific procedures that must be followed exactly, or you'll lose your right to payment forever. Understanding these rules can mean the difference between getting paid and losing thousands of dollars on a public project.
What is the Little Miller Act
California's Little Miller Act, found in Civil Code sections 9550-9566, is the state version of the federal Miller Act. This law requires payment bonds on most public construction projects over $25,000 in California. The payment bond serves as a guarantee that all contractors, subcontractors, suppliers, and laborers will be paid for their work and materials on the project.
The Little Miller Act creates a legal framework that allows unpaid parties to make claims against these payment bonds when they haven't received payment from the contractor above them in the payment chain. Since you can't place a mechanic's lien on government property, the payment bond becomes your primary security for getting paid on public projects.
Under this law, the surety company that issued the payment bond becomes responsible for investigating valid claims and making payments when the principal contractor fails to pay. The bond amount is typically equal to the full contract amount, providing substantial security for all parties working on the project.
When contractors use Little Miller Act claims
• Unpaid subcontractor work: When a general contractor fails to pay a subcontractor for completed work on a public project • Unpaid material suppliers: When suppliers haven't been paid for materials delivered to a public construction project • Equipment rental companies: When equipment rental fees remain unpaid after equipment was used on a public project • Second-tier subcontractors: When a subcontractor doesn't pay their own sub-subcontractors or suppliers • Labor and wage claims: When workers haven't received proper payment for work performed on public projects
How the process works
-
Verify bond requirements: Confirm the project required a payment bond by checking with the public entity. Projects over $25,000 typically require bonds, but verify the specific project details and bond information.
-
Gather documentation: Collect all contracts, purchase orders, delivery receipts, invoices, change orders, and proof of work completion. Document all communication attempts regarding payment and maintain detailed records of amounts owed.
-
Send preliminary notice (if required): California requires preliminary notices on many public projects within 20 days of first furnishing labor or materials. Check if this was properly sent, as it may affect your bond claim rights.
-
File the bond claim: Submit your written claim to the surety company within 6 months of your final furnishing of labor or materials. The claim must include specific information about the work performed, materials supplied, amounts owed, and the parties involved.
-
Wait for surety response: The surety company will investigate your claim, which typically takes 30-90 days. They may request additional documentation or clarification during this process.
-
File lawsuit if necessary: If the surety denies your claim or doesn't respond adequately, you must file a lawsuit within 6 months of completing your work to preserve your rights under the bond.
Common mistakes contractors make
• Missing the 6-month deadline: Failing to file the bond claim within 6 months of final furnishing labor or materials automatically bars your claim forever, regardless of how much money is owed
• Inadequate claim documentation: Submitting bond claims without sufficient supporting documentation, proper invoices, proof of delivery, or clear descriptions of work performed
• Not identifying the correct surety: Filing claims with the wrong surety company or using outdated bond information, which can waste precious time within the 6-month deadline
• Failing to send preliminary notices: Not providing required preliminary notices within 20 days can limit or eliminate your bond claim rights on certain California public projects
• Incomplete claim information: Omitting required details like project names, contract numbers, dates of work, or proper legal descriptions of the public entity and contractor relationships
Typical lawyer cost vs Lienra
Construction attorneys in California typically charge $300-$600 per hour for bond claim work, with total costs often ranging from $3,000-$8,000 for a straightforward claim and $10,000-$25,000 if litigation becomes necessary. These high costs can make it uneconomical to pursue smaller bond claims, even when you have valid rights to payment.
