How to Send a Notice of Lawsuit to Workers' Compensation in California

Why the Notice Matters

In California, a workers' compensation claim must be filed within 30 days of injury. If a claimant decides to pursue a lawsuit in civil court, a notice of lawsuit must be served on the employer and the workers' compensation board. The notice preserves rights, triggers the waiver of the administrative benefits, and allows the claim to move into the civil arena.

Timing and Deadlines

California law imposes strict timing. The claimant must serve the notice no later than 60 days after the claim is filed with the Workers' Compensation Appeals Board (WCAB). Missing this deadline can forfeit the right to sue. It is crucial to track dates from the injury, claim filing, and any board decisions.

Required Documents

To comply with the statute, the claimant must provide:

• Form WC 1‑10 (Notice of Claim) if not already filed.
• Form WC 1‑25 (Notice of Lawsuit) detailing the claim and the desired damages.
• Proof of service, such as a certified mail receipt or a return receipt from the employer.
• Any supporting evidence: medical reports, witness statements, or payroll records.

How to Serve the Notice

The notice must be personally served on the employer's designated representative. If personal service is impractical, certified mail with return receipt is acceptable. The notice must also be filed with the WCAB within the same 60‑day period. Keep copies of all documents and proof of service for court records.

Legal Consequences of Non‑Compliance

Failing to file the notice within the statutory window can result in:

• Loss of the right to pursue a civil lawsuit.
• Continuing eligibility for workers' compensation benefits.
• Potential penalties for procedural violations.

Best Practices for Claimants

Claimants should:

• Consult an attorney experienced in workers' compensation litigation.
• Maintain a detailed timeline of events.
• Use a reputable service to handle document filing and service of process.
• Keep all medical and payroll documentation organized for easy reference.

Employer's Response and Possible Outcomes

Once the notice is served, the employer has 30 days to respond. A timely response may lead to settlement negotiations or dismissal of the lawsuit if the claim is deemed insufficient. If the employer fails to respond, the claimant can proceed with filing the civil action in the appropriate court.
