How do lien rights work for unpaid commercial invoices in CA?

On Behalf of | Jul 10, 2025 | Commercial Collections |

When a commercial client fails to satisfy an invoice, California law provides mechanisms—specifically lien rights—that enable you to secure and recover unpaid amounts. These legal tools require precision, contractual foresight, and timely action to remain enforceable.

What types of liens apply to business invoices?

Two lien types commonly apply in commercial transactions: the retention of title and the artisan’s lien. A retention-of-title clause, typically embedded within a sales contract, allows you to retain ownership of goods until the purchaser completes payment. An artisan’s lien, on the other hand, permits you to hold possession of property you’ve repaired or enhanced until the debt is satisfied. Both mechanisms serve as lawful methods to mitigate nonpayment risks in business exchanges.

What steps must you take to enforce a lien?

To assert a lien, ensure your contract or invoice includes a clearly articulated clause granting lien rights. When a client defaults, you must issue a formal written demand and provide legally required notice before initiating enforcement actions, such as withholding or liquidating the secured asset. If the client contests your claim, litigation may become necessary. Omitting procedural steps could invalidate your lien and compromise your legal standing.

When do lien rights lapse?

Lien rights are time-sensitive. In California, an artisan’s lien typically expires one year after the services are rendered. Retention-of-title provisions depend heavily on the contract language and may be affected by events such as bankruptcy filings or asset transfers. Meticulous tracking of statutory deadlines is essential to preserve your enforcement rights.

How should you address lien disputes?

When disputes arise, proactive negotiation—such as offering structured payment terms or partial settlements—can resolve issues without judicial intervention. Mediation also provides a structured forum to reach consensus. Courts tend to view businesses more favorably when they demonstrate good-faith efforts to settle disputes before escalating the matter.

Once you enforce a valid lien, you may retain or liquidate the property to recover the outstanding amount. You must follow proper notice procedures and ensure any surplus from a sale returns to the debtor. If the asset’s value falls short, you retain the right to pursue a deficiency judgment through the courts.
