Labor Code §3852 says that filing a workers’ comp claim does not take away your right to sue someone other than your employer, such as a negligent driver, a property owner or an equipment maker, for all damages caused by your injury. Your employer, or its insurer, can also pursue that third party to get back what it paid in benefits.
Workers’ comp is usually your only remedy against your own employer. Section 3852 keeps the door open against everyone else. A civil claim can seek “all damages proximately resulting from the injury or death,” which reaches beyond the formula benefits workers’ comp pays. In return, the law gives the employer a share of the recovery and, in most cases, a credit against future benefits. For a broader look at when you can bring a lawsuit outside the comp system, see our guide Can I sue outside of workers’ comp? If your case involves a head injury, our guide to traumatic brain injuries and third-party liability covers those claims. This page explains the statute and the sections that work with it.
- Labor Code §3852 says a workers’ comp claim does not affect your right to sue “any person other than the employer” for all damages from the injury or death.
- Your employer or its insurer can also sue the third party, or join your case, to recover what it paid in benefits.
- Expenses and attorney’s fees come first; the employer is then reimbursed and can generally take a credit against future benefits (§§3856, 3858, 3860, 3861).
- Since January 1, 2026 (SB 487), employers of covered peace officers and firefighters can recover no more than one-third of the third party’s policy limits when insurance falls short, with no future-benefit credit.
- Most injury lawsuits must be filed within two years (CCP §335.1), and claims against public entities have a much shorter claim deadline.
What Labor Code §3852 says
Section 3852 has two subdivisions. Subdivision (b) is new: it was added by Senate Bill 487 (Chapter 763, Statutes of 2025) and took effect January 1, 2026.
Subdivision (a): your claim against third parties survives
“The claim of an employee, including, but not limited to, any peace officer or firefighter,” for workers’ comp “does not affect their claim or right of action for all damages proximately resulting from the injury or death against any person other than the employer.” The same subdivision lets an employer that has paid, or become obligated to pay, compensation or salary in lieu of compensation “make a claim or bring an action against the third person.” In that suit the employer can recover the compensation plus salary, wages, pension or other benefits it paid to the employee or dependents. If the worker died, the heirs can bring a wrongful death claim under Code of Civil Procedure §377.60, and “the respective rights against the third person” of the heirs and the employer “shall be determined by the court.”
Subdivision (b): a cap for certain public safety employers (2026)
Subdivision (b) “applies only to an employee who is a peace officer,” as defined in Penal Code §830 and the sections that follow, “or a firefighter who is employed by” a city, a county, a city and county, or a fire protection district. For those workers, the employer may recover “no more than one-third of a third-party defendant’s applicable liability insurance policy limits,” but only when both of these are true:
- The employee shows that their total damages exceed the net recovery left after the employer’s claim is paid.
- The total liability insurance available is not enough to fully compensate both the employer and the employee’s proven damages.
The cap “shall take precedence over any employer lien or subrogation claim.” SB 487 also amended §§3858, 3859, 3860, 3861 and 3862. Under §§3858 and 3861, the employer in these cases cannot take a credit against future workers’ comp benefits. Under §3860, a release or settlement in these cases is not valid or binding unless it provides that the employer “shall not receive more than one-third of the third-party insurance limits.”
Who §3852 covers
- Any injured employee whose injury was caused, at least in part, by someone other than the employer.
- Families in death cases. Subdivision (a) refers to damages from “the injury or death” and to heirs claiming under the wrongful death statute.
- Employers and their insurers, who may sue the third party themselves or join your case.
- Public safety workers described in subdivision (b), who get the 2026 cap on the employer’s share.
Common third parties include an at-fault driver in a work-related crash, the owner of a property where you were hurt on the job, the maker of a defective machine or tool, and another company whose workers caused the accident. Our guides on a car accident while driving for work and on being crushed by machinery at work cover two of the most frequent situations.
Section 3852 does not let you sue your own employer. That is generally barred by the exclusive remedy rule in Labor Code §3602, which has its own exceptions. An employer that failed to carry workers’ comp insurance can be sued under Labor Code §3706.

How the recovery is shared: §§3853 to 3861
Section 3852 opens the door. The sections right after it decide who gets what.
- Notice and joining the case (§3853). If you or your employer sues, the one who sues must promptly serve the other with a copy of the complaint by personal service or certified mail. The other may join as a co-plaintiff, or consolidate a separate suit, at any time before trial on the facts.
- Judgments (§3856). If you sue alone and win, the court first pays reasonable litigation expenses and your attorney’s fee. The employer can then ask for a “first lien” on the judgment for the compensation it paid.
- Settlements (§3860). A settlement of the third-party claim is not valid or binding unless both you and the employer got notice and a chance to protect what each is owed. Reasonable expenses and attorney’s fees come out of the settlement before the employer is reimbursed. In §3852(b) cases, the employer’s reimbursement is limited to the portion of the settlement allocated to it.
- Future benefits (§§3858 and 3861). After expenses, fees and the employer’s reimbursement, the employer is generally relieved of paying further compensation up to the balance you received. The Workers’ Compensation Appeals Board allows that credit. For subdivision (b) public safety cases, no credit against future benefits is allowed.
A driver, property owner or equipment maker may owe you damages that workers’ comp doesn’t pay. The two claims have to be coordinated from the start.

How it plays out
💡 Example: Tomás, a hypothetical delivery driver, is rear-ended by another motorist while on his route in 2026. Workers’ comp pays $30,000 in medical and temporary disability benefits. Tomás settles with the at-fault driver for $150,000, with notice to his employer’s insurer. To keep the arithmetic simple, assume the approved litigation expenses and attorney’s fees total $50,000. That leaves $100,000. The insurer is reimbursed its $30,000, and Tomás receives the remaining $70,000. Under §3861, the Workers’ Compensation Appeals Board can then generally allow the insurer a credit of up to $70,000 against future comp benefits: if Tomás later needs another $20,000 in treatment for the same injury, that cost can be charged against the credit instead of paid by the insurer, and $50,000 of credit would remain. Had Tomás been a city firefighter covered by §3852(b), with total damages above what he would net after the employer’s claim and a driver’s policy too small to cover everyone, the employer’s share would be capped at one-third of the policy limits, with no credit against future benefits.
What to do if someone else caused your work injury
- File your workers’ comp claim. Section 3852 lets you pursue both.
- Get the names, insurance details and police or incident report numbers for anyone else involved.
- Keep the evidence: photos, the tool or part that failed, and witness contact information.
- Tell your workers’ comp lawyer about the third party early, and tell any civil lawyer about your comp claim, so the lien and credit are handled together.
- Don’t sign a release with the third party or its insurer before you understand how the employer’s claim will be resolved.
- Calendar the civil deadline. The two-year clock in most injury cases runs separately from the comp deadlines, and claims against public entities move much faster.
Frequently asked questions
Does a workers’ comp claim affect my right to sue a third party under §3852?
No. Labor Code §3852(a) says your workers’ comp claim does not affect your right to sue “any person other than the employer” for all damages caused by the injury.
Do I have to pay workers’ comp back out of my third-party recovery?
Usually, in part. After expenses and attorney’s fees, the employer can be reimbursed for compensation it paid (§§3856 and 3860), and it can generally take a credit against future benefits for what you net (§§3858 and 3861). Subdivision (b) limits this for covered public safety workers.
Can I use §3852 to sue my employer?
No. Section 3852 is about “any person other than the employer.” Claims against your own employer are generally limited to workers’ comp under §3602, with specific exceptions, and §3706 for uninsured employers.
What changed in §3852 in 2026?
SB 487 added subdivision (b), effective January 1, 2026. For covered peace officers and firefighters (the text lists firefighters employed by a city, county, city and county, or fire protection district), the employer’s recovery is capped at one-third of the third party’s liability policy limits when the insurance can’t cover everyone, and the employer gets no credit against future benefits.
Does my employer’s insurer have to know about my settlement?
Under §3860, a settlement of the third-party claim is not valid or binding unless both the employee and the employer received notice and an opportunity to recover what each is owed. Section 3859 adds written-consent rules for some settlements.
Does §3852 cover a worker who died?
Yes. Subdivision (a) covers damages from “the injury or death.” The worker’s heirs can bring a wrongful death claim, and the court decides how their rights and the employer’s rights against the third party fit together.
