By Eman Yazdchi, Esq. · Certified Specialist in Workers' Compensation Law, State Bar of California Board of Legal Specialization
In California, every employer must carry workers' comp insurance under §3700. An uninsured employer faces criminal liability under §3700.5, and the worker can sue in civil court outside the §3601 exclusive-remedy bar under §3706, plus file with the UEBTF. Yazdchi Law, a Certified Specialist in Workers' Compensation Law firm, handles these cases.
For an injured California worker, discovering that the employer never carried workers' compensation insurance is one of the harder shocks in the case. The worker reports the injury, asks for the DWC-1, and finds out there is no insurance carrier — or the supervisor admits "we don't have workers' comp." Many workers assume they have no claim at all. They are wrong, and they often have stronger options than workers with insured employers, not weaker ones.
This guide walks through what California law actually does when the employer is uninsured: the criminal liability under California Labor Code §3700.5, the worker's right to sue in civil court under California Labor Code §3706 (outside the normal exclusive-remedy bar of California Labor Code §3601), the Uninsured Employers Benefits Trust Fund claim path, and the general-contractor exposure under California Labor Code §2810 when a subcontractor is uninsured.
The short version: California requires every employer with even one employee to carry workers' compensation insurance under California Labor Code §3700. Failure is a misdemeanor under California Labor Code §3700.5. An injured worker of an uninsured employer can both sue the employer civilly under California Labor Code §3706 (with the §3601 exclusive-remedy bar lifted) and pursue benefits through the state-administered Uninsured Employers Benefits Trust Fund. For workers of a subcontractor, California Labor Code §2810 can put liability on the general contractor.
Under California Labor Code §3700, every California employer with at least one employee must secure workers' compensation insurance — either through a licensed California insurance carrier, through approved self-insurance, or through approved group insurance. There are no exceptions for small employers, family businesses, or "informal" arrangements. A California employer with one part-time employee must carry workers' comp insurance from day one.
Under California Labor Code §3700.5, failure to carry workers' compensation insurance is a misdemeanor. The penalty includes criminal fines, potential jail time, and substantial civil penalties payable to the state. An uninsured employer is also exposed to a stop-work order from the California Department of Industrial Relations, shutting down the operation until insurance is in place.
Under California Labor Code §3706, when an employer is uninsured, the normal exclusive-remedy bar of California Labor Code §3601 does not apply. The §3601 rule is the "grand bargain" of California workers' compensation: in exchange for no-fault workers' comp benefits, the worker generally cannot sue the employer in civil court for negligence. But when the employer fails to carry insurance — fails to hold up the employer's end of the grand bargain — the §3601 bar is lifted, and the worker can sue civilly.
The §3706 civil action is a major right. In civil court, the worker can recover damages that workers' compensation does not provide: pain and suffering, full lost wages (not the two-thirds capped under California Labor Code §4653), full medical expenses (not subject to UR and IMR), and in some cases punitive damages. The civil action runs alongside (not instead of) the workers' comp claim, which means the worker can also pursue UEBTF benefits.
The Uninsured Employers Benefits Trust Fund (UEBTF) is a state-administered fund that pays workers' compensation benefits to injured workers whose employers were uninsured at the time of the injury. The UEBTF stands in the shoes of the absent insurer — paying medical care under California Labor Code §4600, temporary disability under California Labor Code §4653, and permanent disability under California Labor Code §4660, then seeking reimbursement directly from the uninsured employer.
The UEBTF claim is filed at the WCAB with the standard DWC-1, naming both the uninsured employer and the UEBTF as parties. The UEBTF investigates, may dispute compensability, and provides benefits if the claim is accepted. The state's enforcement against the uninsured employer is separate from the worker's recovery — meaning the worker is not waiting for the employer to pay before benefits flow.
The two paths are complementary, not exclusive. A specialist attorney typically files both: the §3706 civil action against the uninsured employer for the full range of civil damages, and the workers' comp / UEBTF claim for statutory workers' comp benefits. The civil court action and the WCAB proceeding run on separate tracks with separate evidence and separate remedies.
The strategic value of the dual-track approach is leverage. An uninsured California employer facing both a civil lawsuit and state enforcement under California Labor Code §3700.5 has substantial financial exposure — criminal fines, civil penalties, the civil judgment, and reimbursement to the UEBTF. The combined pressure often produces settlement value that exceeds what a workers' comp-only claim could deliver.
Under California Labor Code §2810, a California general contractor that hires a subcontractor it knew or should have known was unable to comply with workers' compensation insurance requirements is liable for the subcontractor's workers' comp obligations. The §2810 rule exists to prevent general contractors from insulating themselves by hiring uninsured subs.
For an injured worker of an uninsured subcontractor, the §2810 claim against the general contractor is often the most valuable path. The general contractor typically has substantial insurance and assets, where the subcontractor may have neither. A specialist attorney evaluates the general contractor's knowledge — direct knowledge, willful blindness, or constructive knowledge under the "knew or should have known" standard — and structures the claim to put liability on the GC under §2810.
Every California workers' comp protection applies regardless of the employer's insurance status. California Labor Code §4600 requires medical care; California Labor Code §132a prohibits retaliation against the worker for filing the claim; California Labor Code §3351 extends coverage to every worker regardless of immigration status; California Labor Code §244 prohibits immigration-status threats; California Labor Code §5811 entitles the worker to a qualified interpreter at WCAB hearings, depositions, and medical-legal exams. The worker's medical needs do not wait for the employer's enforcement outcome — UEBTF benefits begin once the claim is accepted, and an adverse Findings and Award can be challenged via Petition for Reconsideration within 25 days of service by mail (or 20 days from electronic service) under California Labor Code §5903.

Tap to call →Discovering the employer has no workers' comp insurance is a setback that quickly becomes an advantage when the worker has the right legal team. The §3706 civil action removes the §3601 exclusive-remedy bar, the UEBTF provides baseline benefits, and §2810 can put a general contractor on the hook for an uninsured sub. The framework was built for these cases.
The DWC-1 still gets filed when the employer is uninsured — both the uninsured employer and the UEBTF are named as parties. The UEBTF stands in for the absent insurer and pays medical care under California Labor Code §4600, temporary disability under California Labor Code §4653, and permanent disability under California Labor Code §4660. The worker's benefits do not wait for the state's enforcement against the employer; they flow through the UEBTF once the claim is accepted.
The civil action under California Labor Code §3706 runs alongside the workers' comp claim — not instead of it. In civil court, the worker can recover damages the comp system does not provide: pain and suffering, full lost wages, full medical expenses outside UR, and in some cases punitive damages. The dual-track approach combines civil pressure with comp benefits, and often delivers settlement value exceeding what either path would produce alone.
California workers' compensation attorneys work on contingency under California Labor Code §4906 — typically 15% of any settlement, paid only if the case recovers. A free consultation costs nothing, and a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California, can evaluate the uninsured-employer claim, the UEBTF path, the §3706 civil action, and any §2810 general-contractor exposure within days.
