How to Look Up a Workers' Compensation Case in California

Why California Has a Separate Workers' Compensation System

California's Division of Workers' Compensation (DWC) handles all workers' comp claims, keeping records in a centralized database. Unlike many states that use a single state court, California's system is state‑administered and publicly accessible, which means case details can be requested through the DWC's online portal or by mail.

What You Need Before You Request a Case File

Before filing a request, gather the following:

• Case number (if known)
• Claimant's full name and date of birth
• Employer's name and address
• Reason for the claim (e.g., injury date, nature of injury)

Having these details speeds the search and reduces the risk of a denial due to incomplete information.

Online Search via the DWC Portal

Navigate to the DWC's official website and select "Case Lookup." Enter the claimant's name or case number. The system returns a summary that includes:

• Case status (Open, Closed, Pending)
• Current hearing dates
• Assigned judge or arbitrator

Note that the portal displays only publicly available information; confidential data requires a formal request.

Submitting a Formal Request for Records

If you need full case files, file a written request under the California Public Records Act. Include:

• Your name, address, and phone number
• Specific documents requested (e.g., medical reports, hearing transcripts)
• Statement of purpose (e.g., attorney representation, employee rights inquiry)

Mail or email the request to the DWC's Records Department. Processing typically takes 10–15 business days, and a small fee may apply.

Common Reasons for Denial and How to Avoid Them

Requests are often denied if:

• Information is incomplete or ambiguous
• The requester is not a party to the case
• Requested documents are protected under privacy laws

To mitigate denial, double‑check the claimant's full name, include all relevant identifiers, and, if possible, provide proof of legal standing.

Alternative Sources for Case Information

When the DWC's portal or records request does not yield results, consider:

• County clerk's office for related civil filings
• California Labor Commissioner's office for enforcement actions
• Legal databases such as Westlaw or LexisNexis for published opinions

These sources can supplement missing data or provide context on related legal decisions.
