Unpaid as a Contractor? California's Payment Remedies Stack

An overdue invoice can strain a contractor’s cash flow, but California law does not offer one remedy for every unpaid job. A consultant may have a contract claim; a construction contractor may also have lien or bond rights; and a worker labeled an independent contractor may actually be an employee. This article explains how those payment remedies can overlap, what deadlines deserve attention, and how California businesses and individuals can choose a practical next step.

“Contractor not paid California”: which rules apply?

Start by identifying your work, your customer, and your legal status. The word “contractor” can describe a freelance designer, an individual providing services, a licensed builder, or a construction subcontractor. Those categories carry different rights.

  • Independent service provider: Your agreement and proof of performance usually form the foundation of a payment claim.
  • Construction contractor or supplier: Mechanics liens, stop payment notices, and payment bonds may provide additional routes to recovery.
  • Potential employee: Wage protections may apply even if your agreement calls you an independent contractor.

California’s ABC test under Labor Code section 2775 applies to many worker-classification questions, but exceptions and other tests exist. A label or tax form alone does not settle classification. If you may be an employee, unpaid wages may belong in a Labor Commissioner claim or another employment-law proceeding rather than an ordinary invoice dispute.

Build the contract claim before demanding payment

Collect the signed agreement, approved estimates, change orders, invoices, delivery records, emails, and evidence that the customer accepted your work. Identify the correct debtor: a company’s owner is not automatically personally responsible for its debts.

A useful demand states the amount owed, the contractual payment deadline, the work supporting the charge, and a reasonable response date. Separate undisputed charges from disputed extras. If the customer claims defective or incomplete work, request specifics and preserve your response.

California generally allows four years for an action on a written contract under Code of Civil Procedure section 337 and two years for an oral-contract action under section 339. Accrual, tolling, and the nature of the claim can affect those periods. Construction security deadlines are often much shorter, so do not treat the contract limitation period as your only deadline.

Attorney fees and interest also require analysis. A contract or statute may authorize fees; they are not available in every collection case. Itkin Law’s debt collection services address payment disputes for businesses and individuals, including evaluating the available claims before filing.

Protect construction lien and bond rights early

For qualifying work on private property, a mechanics lien can secure payment against the improved property. It is separate from your personal claim against the customer. Eligibility, licensing, notices, recording, and enforcement all matter.

  • Preliminary notice: Under Civil Code sections 8200 and 8204, claimants generally must give preliminary notice before recording a lien, serving a stop payment notice, or asserting a payment-bond claim, subject to statutory exceptions. Notice is generally due within 20 days after first furnishing work; a late notice generally preserves rights only for work furnished during the 20 days before service and afterward. Laborers are exempt, and a direct contractor with a direct contractual relationship with the owner generally need give preliminary notice only to the construction lender, if any.
  • Recording deadline: Under Civil Code sections 8412 and 8414, a lien generally must be recorded before the earlier of 90 days after completion of the work of improvement or the applicable period after a valid notice of completion or cessation is recorded—60 days for a direct contractor and 30 days for other claimants. Statutory service requirements and exceptions also affect whether the shortened deadline applies; under section 8190, an owner’s failure to give a claimant required notice prevents the shortened period from applying to that claimant. A direct contractor may record only after completing its direct contract; other claimants may record only after ceasing to provide work.
  • Enforcement deadline: Civil Code section 8460 generally requires a lien-enforcement action within 90 days after recording the lien.

Completion has a statutory meaning; it is not always your last day on site. Negotiations generally do not extend these deadlines.

Mechanics liens generally cannot be enforced against public property. Depending on the public project and claimant’s role, statutory payment-bond and stop-payment-notice remedies may be available, each with separate notice, timing, and enforcement requirements. Private projects may also involve bond or stop payment rights.

Licensing is critical. Business and Professions Code section 7031 generally bars an unlicensed contractor from recovering compensation for work requiring a contractor’s license unless the contractor was properly licensed throughout performance, subject to limited statutory exceptions. Section 7031(b) permits the person who used the unlicensed contractor’s services to seek recovery of compensation paid to that contractor, subject to statutory exceptions.

Check prompt-payment rights without overstating them

California construction prompt-payment statutes can supplement contract rights. Civil Code section 8800 addresses qualifying private-work progress payments from owners to direct contractors, including payment timing and penalties for certain wrongful withholding.

Different provisions govern downstream payments, retention, and public projects. Whether a penalty applies depends on the parties, payment type, contract terms, and any good-faith dispute. Late payment does not automatically establish entitlement to every construction penalty.

These remedies can work together: a contract claim seeks payment, while a lien or bond claim may add a source of recovery. But overlapping claims do not permit collecting the same unpaid amount twice.

Choose a collection path that fits the debt

Before filing, compare the amount owed with litigation costs, the debtor’s assets, and any arbitration clause. A judgment establishes liability but does not itself put money in your account.

  1. Consider small claims: California generally permits natural persons, including sole proprietors, to seek up to $12,500; corporations, partnerships, and most other entities are limited to $6,250. A natural person generally may file no more than two claims anywhere in California during a calendar year seeking more than $2,500. Claims for $2,500 or less are not subject to that two-claim limit; other small-claims rules and exceptions apply.
  2. Evaluate civil litigation or arbitration: Larger claims, complex disputes, and lien enforcement may require a different forum.
  3. Document any settlement: Specify payment dates and release terms. Review lien waivers carefully before signing, especially unconditional waivers before payment arrives.

Preserve deadlines while discussing payment. A promise to pay next month is not a substitute for protecting an expiring remedy.
