The Application for Adjudication of Claim is the form that opens a case with California's workers' compensation court, the Workers' Compensation Appeals Board (WCAB). Filing it gives you a case number and the right to have a judge decide disputes about your benefits. It is different from the claim form you give your employer.
DWC-1 claim form vs. the Application
| DWC-1 claim form | Application for Adjudication | |
|---|---|---|
| Who gets it | Your employer | The WCAB (workers' comp court) |
| What it does | Starts your workers' comp claim with the insurer | Opens a court case so a judge can resolve disputes |
| When | As soon as possible after the injury. Your employer must give you the form within one working day after learning of it (Labor Code 5401) | When there is a dispute, or when you need a judge to approve a settlement |
| What happens next | The insurer has up to 90 days to accept or deny the claim (Labor Code 5402) | You get a case number and the other side is served |
Turning in a DWC-1 does not open a court case. Only the Application does that (8 CCR 10450).
When to file the Application
Common reasons:
- the insurer denied your claim or is delaying it,
- your checks stopped, came late, or were figured too low,
- treatment was denied and you need the court's help,
- you disagree with a disability rating,
- you are ready to settle and need a judge to approve it.
Deadlines that protect your case
- One year. In most cases, a claim must be filed within one year of the injury, or within one year of the last benefit payment (Labor Code 5405).
- Five years. If your condition gets worse after an award, you can ask for more benefits within five years of the date of injury (Labor Code 5410).
Missing a deadline can end your right to benefits, so do not wait if the insurer is not paying.
Who files it and where
Your lawyer usually files the Application electronically. Workers without a lawyer can file it too, and the state's Information and Assistance officers can help. The case is assigned to a WCAB district office based on the venue rules in Labor Code 5501.5, which look at where you live, where you were hurt, and, if you have a lawyer, where your lawyer's office is.
What happens after you file
- The WCAB assigns a case number and the other side is served.
- Medical evaluations, records and settlement talks move forward.
- When the case is ready for a judge, a party files a Declaration of Readiness to Proceed.
- The court sets a Mandatory Settlement Conference. If the case does not settle there, the judge sets it for trial.
- Most cases settle before trial. A judge still has to approve the settlement.
