In California, Labor Code section 3700.1 establishes and administers the California Uninsured Employers Benefits Trust Fund (UEBTF) — the state-administered fund that pays workers' compensation benefits to California injured workers whose employers violated the §3700 insurance requirement by going uninsured.
California Labor Code section 3700.1 establishes and administers the California Uninsured Employers Benefits Trust Fund (UEBTF) — the state-administered fund that pays workers' compensation benefits to California injured workers whose employers violated the California Labor Code §3700 California insurance requirement by going uninsured. Under section 3700.1, the California UEBTF steps in when a California employer was supposed to carry workers' compensation insurance under California Labor Code §3700 California but failed to do so, and a worker is then injured on the job. The section 3700.1 California UEBTF pays the California injured worker the same statutory benefits the worker would have received if the California employer had properly carried insurance — TD, PD, medical, vocational, and death benefits.
Under California Labor Code section 3700.1, the California UEBTF is funded by a combination of sources: civil penalties collected from uninsured California employers under California Labor Code §3700.5 California; surcharges and assessments on the California workers' compensation insurance industry; and recoveries the California UEBTF obtains by stepping into the shoes of California injured workers and pursuing the uninsured California employer personally for the benefits paid. The section 3700.1 California UEBTF funding model means the cost of California uninsured-employer claims is ultimately borne partly by the California insurance industry (through assessments) and partly by the uninsured California employers themselves (through California Labor Code §3700.5 California penalties and California Labor Code §3706 California civil-liability recoveries).
Under California Labor Code section 3700.1, the California UEBTF pays benefits through the same WCAB adjudication process that applies to insured cases. The California injured worker files an California Labor Code section 5500 Application for Adjudication naming both the California uninsured employer and the section 3700.1 California UEBTF as defendants; the WCAB judge determines liability and benefits; and the section 3700.1 California UEBTF pays the benefits while pursuing reimbursement from the California uninsured employer personally. The section 3700.1 California UEBTF benefit timing can be slower than insured-employer benefits because of the multi-party adjudication, but the California UEBTF ultimately pays the full statutory benefit due.
Under California Labor Code section 3700.1 and California Labor Code §3706 (uninsured-employer civil liability), the California UEBTF aggressively pursues recoveries from California employers who violated California Labor Code §3700 California by going uninsured. The section 3700.1 California UEBTF can obtain WCAB judgments against the uninsured California employer personally, file civil-court actions to collect, place liens on the California employer's assets, and seek criminal referrals under California Labor Code §3700.5 California for failure to insure. The section 3700.1 California UEBTF recovery effort is essential to maintain the California UEBTF's funding base; California uninsured employers face substantial personal liability that survives the corporate veil under California Labor Code §3706 California.
Under California Labor Code section 3700.1 (UEBTF), California Labor Code §3700 (insurance requirement), California Labor Code §3700.5 (criminal misdemeanor for failure to insure), and California Labor Code §3706 (uninsured-employer civil liability), the California uninsured-employer framework operates as a multi-layer enforcement system. California Labor Code §3700 California requires the California employer to carry workers' compensation insurance; California Labor Code §3700.5 California criminalizes failure to do so; California Labor Code §3706 California creates civil liability against the uninsured California employer personally; and section 3700.1 California UEBTF pays the California injured worker while pursuing recovery from the California employer. The four California sections together build the California uninsured-employer enforcement framework.
