The California DWC-1 Employee’s Claim for Workers’ Compensation Benefits is the official one-page form an injured worker uses to open a workers’ compensation claim with their employer in California, and it triggers strict legal duties under Labor Code §5401. The current revision is the DWC 1 (rev. 1/2016), distributed as part of the Notice of Potential Eligibility packet by the California Division of Workers’ Compensation.
Filing this form correctly starts the 90-day presumption clock under Labor Code §5402, unlocks up to $10,000 in medical treatment, and protects the worker’s right to all benefits. According to the DWC 2024 Audit Report, more than 460,000 DWC-1 claims are filed every year in California, and roughly 18% are initially delayed or denied because of avoidable form errors.

What the DWC-1 Is and Who Must File It
The DWC-1 is the Employee’s Claim for Workers’ Compensation Benefits form that every California employer must give an injured worker within one working day of learning about a workplace injury, as required by 8 CCR §10119. The injured worker fills in the “Employee” section, signs and dates it, and gives it back to the employer. The employer then completes the “Employer” section and forwards the form to the claims administrator within one working day under Labor Code §5401(b).
Every California employer with at least one employee must keep DWC-1 forms on hand, even sole-proprietors who hire one part-time worker. The duty applies to public agencies, school districts, farm labor contractors, and household employers. Independent contractors are not covered, but misclassification disputes often turn on whether the worker should have received a DWC-1 at all, as the California Supreme Court explained in Dynamex v. Superior Court.
The form opens a claim, but it is not the same as the WCAB Application for Adjudication of Claim. The DWC-1 starts the administrative process with the carrier. The Application for Adjudication is filed later, with the Workers’ Compensation Appeals Board through EAMS, only when there is a dispute that needs a judge.
Failing to provide the DWC-1 does not erase the claim. The Honeywell v. WCAB (2005) 35 Cal.4th 24 ruling holds that the 90-day presumption of compensability runs from the date the employer receives the form, not the date of injury, which is why the date stamp on the form is so important.
Before You Start: Documents and Information You Need
Gathering documents before opening the form prevents 90% of common errors. The DWC-1 looks short, but each line cross-references other records the carrier will pull. Missing a single number can stall benefits for weeks.
- 📇 Government photo ID. Driver’s license or California ID. The name on the form must match exactly, because the carrier cross-checks against EDD wage records.
- 🧮 Social Security Number. Required on the employee section. A missing or wrong SSN delays the EDD wage match and the temporary disability calculation.
- 🏠 Current mailing address. All notices, including the Notice of Denial or Notice of Delay, are mailed here. A P.O. Box is allowed.
- 📞 Phone number where you can be reached during business hours. The claims adjuster will call within 14 days under 8 CCR §10140.
- 📅 Exact date and time of injury. For cumulative trauma, use the date you first missed work or first saw a doctor for the condition, per Labor Code §5412.
- 📍 Address where the injury happened. Include the street, city, and ZIP. If it happened off-site, note “while traveling for work” and the location.
- 🩺 Body parts injured and how it happened. Plain-language description; medical jargon is not required.
- 🏢 Employer’s legal name, address, and FEIN if known. The DBA on a paystub is not always the legal name; pull it from a W-2 if possible.
- 🛡️ Workers’ compensation carrier name from the workplace poster. Every employer must post the carrier’s name under Labor Code §3550.
- 📝 Predesignation of physician form, if you filed one. This locks in your personal doctor for treatment under Labor Code §4600(d).
- 🧠 Notes about witnesses. You will not list them on the DWC-1, but the adjuster will ask in the recorded statement.
Where to Get the Form and How to Access It
The official DWC-1 lives on the DWC Forms page as a fillable PDF, and it is also embedded inside the Notice of Potential Eligibility packet that employers must hand out. Workers can also pick up a paper copy at any DWC Information & Assistance office, where staff will help fill it out for free.
Most employers give the form in person, by mail, or by email within one working day of learning about the injury. If your employer refuses to give you one, you can download it directly from the state and serve it on your employer yourself. The 90-day presumption clock begins the moment the employer receives the completed form, regardless of who printed it.
The form is two-sided. The front contains the employee section, the employer section, and the signature blocks. The back contains the Notice of Potential Eligibility in English and Spanish. Always print both sides; an employer who receives only the front can argue the notice was incomplete.
For Spanish-speaking workers, the bilingual DWC-1 (Spanish) is on the same page. Filing in Spanish carries the same legal weight as filing in English under Labor Code §3550(b).
Step-by-Step: How to Fill Out DWC-1 Line by Line
The DWC-1 is divided into two main sections: the Employee section (lines 1–8 plus signature) and the Employer section (lines 9–18 plus signature). The claims administrator section sits at the bottom. Fill in only your section; never sign for someone else.
Line 1 — Name (Employee)
This field asks for the injured worker’s full legal name, first, middle, and last. Print legibly in blue or black ink, last name first if the form indicates, and use the exact spelling on your Social Security card. Do not use nicknames, married names you have not legally adopted, or initials.
For example, Maria Elena Lopez writes Lopez, Maria Elena in the name box, exactly as it appears on her SSA card. If your legal name has a hyphen or an apostrophe, include it.
A nuance worth flagging: if you use a different name at work than on your ID, write the legal name here and add the work name in parentheses. This avoids the carrier’s automated EDD mismatch hold.
The most common mistake is using a nickname like Mary instead of Maria. The consequence is a 7–14 day delay while the adjuster requests proof of identity. A misconception is that the name on the paystub controls; it does not — the SSA name controls.
Line 2 — Today’s Date
Enter the date you are signing the form, formatted as MM/DD/YYYY. This is not the date of injury. It is the date you complete the employee section and hand the form back.
For example, Carlos Ramirez writes 05/14/2026 on the day he signs and gives the form to his supervisor. The date here will often differ from the date received stamp the employer enters on Line 17.
A nuance: if you mail the form, write the date you sign it, not the date you drop it in the mailbox. Use a USPS Certificate of Mailing for proof.
The most common mistake is leaving this blank, which makes the carrier argue the form was never properly served. The misconception is that this date starts the 90-day presumption clock; it does not — the employer’s receipt date does, under Labor Code §5402.
Line 3 — Address
Print your current mailing address: street, city, state, ZIP. All official notices, checks, and medical authorizations are sent here. A P.O. Box is acceptable but list a physical address as well if you have one.
For example, Aisha Johnson writes 4421 Magnolia Ave, Apt 2B, Long Beach, CA 90805. If she moves before the claim closes, she must notify the adjuster in writing.
A nuance: homeless or transitional workers can list a shelter address or a trusted relative’s address. The DWC will not deny benefits for lack of a permanent residence.
The most common mistake is using an old address, which causes the Notice of Delay or Notice of Denial to be mailed somewhere the worker no longer lives, and the appeal clock still runs. The misconception is that updating the employer’s HR file is enough; you must also notify the claims administrator directly.
Line 4 — Date of Injury
Enter the date the injury happened in MM/DD/YYYY format. For a specific event, use that date. For cumulative trauma or occupational disease, use the date you first lost time from work or first knew the condition was work-related, per Labor Code §5412.
For example, Janet Nguyen, a nurse with carpal tunnel, writes 03/02/2026 — the day her doctor told her the condition was caused by repetitive charting. Marcus Bell, a warehouse picker, writes 05/10/2026, the day he felt his back pop.
A nuance: post-termination claims are still valid, but the date of injury cannot be after the last day worked unless cumulative trauma rules apply, under Labor Code §3600(a)(10).
The most common mistake is guessing a date months earlier than the §5412 date, which can blow the one-year statute of limitations under Labor Code §5405. The misconception is that a vague “around January” entry is acceptable; carriers reject undated claims.
Line 5 — Time of Injury
Enter the time the injury happened, AM or PM. For cumulative trauma, write N/A — cumulative. For psychiatric injuries, list the time of the precipitating event if there was one.
For example, Marcus Bell writes 2:15 PM. Janet Nguyen writes N/A — cumulative.
A nuance: if you cannot remember exactly, write a reasonable approximation and add (approx.). Carriers accept approximations far more readily than blanks.
The most common mistake is leaving this blank, which the carrier flags as an incomplete claim. The misconception is that the exact minute matters; it does not — the shift window is enough.
Line 6 — Address Where Injury Happened
Print the full address of the location where the injury occurred. If it happened on a job site, list that site, not the employer’s headquarters. If it happened in a vehicle while traveling for work, list the nearest cross-street and city.
For example, Marcus Bell writes Warehouse #7, 1500 Industrial Way, Fontana, CA 92335. Carlos Ramirez, a delivery driver, writes Intersection of Olympic Blvd and Western Ave, Los Angeles, CA — while making delivery.
A nuance: injuries at a company-sponsored holiday party or off-site training are still covered if attendance was expected, per Ezzy v. WCAB. Note the location precisely.
The most common mistake is writing only the city, which gives the carrier room to argue you cannot identify the site. The misconception is that injuries at home are never covered; remote-work injuries can be covered if work-related.
Line 7 — Describe Injury and Part of Body Affected
Describe in plain words what happened and which body parts were hurt. List every body part, even ones that hurt only a little. Adding parts later is allowed but invites carrier challenges.
For example, Marcus Bell writes Lifting a 60-lb box, felt sharp pain in lower back. Injury to lower back, left hip, and left leg (sciatica). Janet Nguyen writes Repetitive charting and IV starts caused numbness, pain, and weakness in both wrists and hands (carpal tunnel).
A nuance: psychiatric and stress-based injuries should be described too, with phrases like anxiety, sleep disturbance, depression secondary to physical injury — these unlock Labor Code §3208.3 benefits.
The most common mistake is listing only the worst body part, which lets the carrier deny treatment for everything else. The misconception is that medical terminology is required; plain English controls.
Line 8 — Employee Signature
Sign and date the form in ink. An electronic signature is acceptable if the employer accepts e-mail filing, per California Civil Code §1633.7. A typed name without a real signature is not enough.
For example, Aisha Johnson signs her name and writes 05/14/2026 next to it, then keeps a photocopy before handing the form over.
A nuance: if you cannot write because of your injury, you may make a mark with a witness, or have a representative sign with a notarized power of attorney.
The most common mistake is signing but not dating, which lets the carrier dispute when the form was completed. The misconception is that filing without a signature is substantial compliance; it is not — the WCAB has rejected unsigned DWC-1s as void.
Line 9 — Employer’s Name (Employer Section)
The employer enters its full legal name, not just the DBA. This must match the name on the workers’ compensation policy, because the carrier matches by FEIN.
For example, Sunrise Logistics, Inc. is the legal name even though the workers know the company as Sunrise Express. The HR rep writes Sunrise Logistics, Inc..
A nuance: staffing-agency workers should see both the staffing agency and the host employer listed. Dual coverage is allowed under Labor Code §3602(d).
The most common mistake is using the DBA, which causes the carrier’s intake system to reject the claim as a non-policyholder. The misconception is that small mismatches are harmless; even one wrong word can route the claim to the wrong carrier.
Line 10 — Employer’s Address
The HR rep enters the employer’s main business address. If the injury site address differs, that should already be on Line 6.
For example, Sunrise Logistics, Inc. lists 2200 Corporate Drive, Ontario, CA 91761. The carrier mails its acknowledgement here.
A nuance: large employers with multiple locations should list the registered agent address from the California Secretary of State Business Search.
The most common mistake is using the injury-site address instead of the policyholder address. The misconception is that any company address is fine; the policy address controls for carrier routing.
Line 11 — Date Employer First Knew of Injury
The employer enters the date a supervisor or HR rep first learned about the injury. This date triggers the one-working-day duty under 8 CCR §10119.
For example, the supervisor at Sunrise Logistics writes 05/10/2026 because Marcus told his lead the same day he got hurt.
A nuance: knowledge by any supervisor counts as knowledge by the employer, even if HR was not told.
The most common mistake is backdating to the same day as the form, which the worker can rebut with witnesses. The misconception is that only written notice counts; verbal notice to a supervisor is enough under Labor Code §5400.
Line 12 — Date Claim Form Given to Employee
Enter the date the employer handed the DWC-1 to the worker. This must be within one working day of Line 11, per Labor Code §5401(a).
For example, the HR rep writes 05/10/2026 — same-day delivery to Marcus.
A nuance: if the employee is hospitalized, the form may be mailed; the postmark counts as the delivery date.
The most common mistake is delaying delivery to “investigate first,” which violates §5401 and exposes the employer to a Labor Code §5814 25% penalty. The misconception is that informal investigation justifies delay; it does not.
Line 13 — Date Claim Form Received from Employee
The employer enters the date the completed, signed form came back. This date starts the 90-day presumption clock under Labor Code §5402.
For example, the HR rep writes 05/14/2026 — the day Marcus turned in the signed form.
A nuance: best practice is to date-stamp the form and sign a receipt for the worker. Workers should always keep a date-stamped copy.
The most common mistake is leaving this blank, which lets the worker argue an earlier date and shorten the 90 days. The misconception is that the 90 days run from the injury date; they run from this receipt date.
Line 14 — Name and Address of Insurance Carrier
The employer enters the workers’ compensation carrier’s full name and claims-handling address. Self-insured employers list themselves and their TPA.
For example, Sunrise Logistics writes Zenith Insurance Company, P.O. Box 9055, Pleasanton, CA 94566.
A nuance: the carrier name must match the DWC’s Self-Insurance and Carrier list. Misnaming a carrier sends the form into a black hole.
The most common mistake is listing the broker, not the carrier. The misconception is that the broker can accept claims; only the carrier or TPA can.
Line 15 — Insurance Policy Number
Enter the active workers’ compensation policy number on the date of injury. Pull it from the DIR Workers’ Comp Coverage Inquiry tool if HR is unsure.
For example, Sunrise Logistics writes ZWC-44991-2026.
A nuance: if the employer was uninsured, list UNINSURED and the worker may file with the Uninsured Employers Benefits Trust Fund (UEBTF).
The most common mistake is using last year’s policy number after a renewal. The misconception is that uninsured employers escape liability; they do not — UEBTF pays and chases the employer.
Line 16 — Employer Representative Signature
The HR rep, owner, or authorized agent signs and prints their title. A signature without a printed name and title is incomplete.
For example, Linda Park, HR Manager signs and prints her name and title.
A nuance: signature authority can be delegated in writing to a TPA. Keep the delegation letter on file.
The most common mistake is having a co-worker sign as a “favor”; this voids the certification. The misconception is that any manager can sign — only authorized representatives can.
Line 17 — Date of Employer Signature
Enter the date the employer rep signs. This should be the same day or within one working day of Line 13.
For example, Linda Park writes 05/14/2026.
A nuance: a signature dated after the carrier’s first benefits decision is suspect and often challenged at WCAB.
The most common mistake is leaving the date blank. The misconception is that the Today’s Date on Line 2 is enough; it is not.
Line 18 — Claims Administrator Section
The carrier or TPA stamps its acknowledgement, claim number, and adjuster contact info. The worker should receive a copy of this completed section within 14 days, per 8 CCR §10140.
For example, Zenith Insurance Company stamps Claim #ZWC-2026-117844, Adjuster Sarah Kim, (800) 555-1212.
A nuance: if the worker does not receive this stamped copy within 14 days, the worker can write the DWC Information & Assistance Unit and request enforcement.
The most common mistake on the carrier’s side is listing only a 1-800 line with no adjuster name. The misconception is that the worker is not entitled to a named adjuster; the worker is.
Three Filled-Out Examples Using Real Scenarios
The three scenarios below show how three different California workers complete the same form. Each illustrates a different fact pattern: specific traumatic injury, cumulative trauma, and post-termination denied claim heading to WCAB.
Scenario 1 — Marcus Bell, Warehouse Worker with Acute Back Injury
| Form Section | What Marcus Enters |
|---|---|
| Line 1 — Name | Bell, Marcus J. |
| Line 2 — Today’s Date | 05/14/2026 |
| Line 3 — Address | 812 Citrus St, Fontana, CA 92335 |
| Line 4 — Date of Injury | 05/10/2026 |
| Line 5 — Time of Injury | 2:15 PM |
| Line 6 — Address Where Injury Happened | Warehouse #7, 1500 Industrial Way, Fontana, CA 92335 |
| Line 7 — Injury and Body Parts | Lifting 60-lb box, felt pop in lower back. Lower back, left hip, left leg. |
| Line 8 — Employee Signature | Marcus J. Bell — 05/14/2026 |
| Employer Carrier | Zenith Insurance — Policy ZWC-44991-2026 |
Scenario 2 — Janet Nguyen, Nurse with Cumulative Trauma
| Form Section | What Janet Enters |
|---|---|
| Line 1 — Name | Nguyen, Janet T. |
| Line 2 — Today’s Date | 03/05/2026 |
| Line 3 — Address | 2244 Westwood Blvd #14, Los Angeles, CA 90064 |
| Line 4 — Date of Injury | 03/02/2026 (per LC §5412 — date of knowledge) |
| Line 5 — Time of Injury | N/A — cumulative trauma |
| Line 6 — Address Where Injury Happened | St. Vincent Medical Center, 2131 W 3rd St, Los Angeles, CA 90057 |
| Line 7 — Injury and Body Parts | Repetitive charting and IV starts. Both wrists, both hands (carpal tunnel), neck, both shoulders. |
| Line 8 — Employee Signature | Janet T. Nguyen — 03/05/2026 |
| Employer Carrier | Sedgwick CMS — Policy SVMC-2026-CT |
Scenario 3 — Carlos Ramirez, Delivery Driver, Post-Termination Claim Heading to WCAB
| Form Section | What Carlos Enters |
|---|---|
| Line 1 — Name | Ramirez, Carlos A. |
| Line 2 — Today’s Date | 04/22/2026 |
| Line 3 — Address | 7710 Atlantic Ave, South Gate, CA 90280 |
| Line 4 — Date of Injury | 03/15/2026 |
| Line 5 — Time of Injury | 11:40 AM |
| Line 6 — Address Where Injury Happened | Olympic Blvd & Western Ave, Los Angeles — during delivery route |
| Line 7 — Injury and Body Parts | Rear-ended in company van. Neck, mid-back, right shoulder, headaches, anxiety. |
| Line 8 — Employee Signature | Carlos A. Ramirez — 04/22/2026 |
| Employer Carrier | State Compensation Insurance Fund — Policy 9876543-2026 |
Carlos was terminated on April 1, 2026. He still has a valid claim because he reported the injury before termination, satisfying Labor Code §3600(a)(10). After his claim is denied, he files a WCAB Application for Adjudication of Claim through EAMS.
How to File the Completed Form
There is no fee to file a DWC-1, but how you deliver it determines your proof and your timeline. California allows four delivery channels for the worker, and each has its own best practice.
In person. Hand the signed form to a supervisor or HR rep at the workplace and ask them to date-stamp a photocopy for you. Processing begins immediately. Your proof is the date-stamped copy.
By certified mail. Mail to the employer’s HR department or registered agent listed on the California Secretary of State Business Search. Use USPS certified mail with return receipt; cost is roughly $5.00. Receipt date is the postal delivery date. Processing time: same as in-person once received.
By email or fax. Allowed if the employer accepts electronic service. Always request an email or fax confirmation back. Keep both the sent and received timestamps. Processing time: same day.
By filing with the carrier directly. If your employer refuses to accept the form, mail it to the workers’ compensation carrier listed on the DIR mandatory workplace poster. The 90-day clock still runs against the carrier. Use certified mail; keep the receipt.
If a dispute develops, the worker (or attorney) files a WCAB Application for Adjudication of Claim electronically through the EAMS portal — there is no filing fee at the WCAB. The Application must be filed within one year of the date of injury under Labor Code §5405.
What Happens After You File
Within one working day of receipt, the employer must authorize up to $10,000 in medical treatment under Labor Code §5402(c). This authorization stands even if the claim is later denied, so long as treatment was reasonable.
Within 14 days, the carrier mails a Notice of Acceptance, Notice of Delay, or Notice of Denial, per 8 CCR §10140. A Notice of Delay gives the carrier up to 90 days to investigate. Silence beyond 90 days creates a presumption of compensability that is very hard to rebut, as confirmed in Rodriguez v. WCAB (1994) 21 Cal.App.4th 1747.
If accepted, the worker is steered into the employer’s Medical Provider Network for treatment, unless the worker properly predesignated a personal physician before the injury. Temporary disability checks begin within 14 days of the first lost workday, paid at two-thirds of average weekly wages, capped at the statewide maximum.
If denied, the worker can challenge the denial by filing a WCAB Application for Adjudication and requesting a Mandatory Settlement Conference. A judge can also order penalties under Labor Code §5814 for unreasonable delay.
Mistakes to Avoid When Filling Out the Form
Each mistake below can delay or destroy a valid claim. Fix them before you sign.
- Listing a nickname instead of the SSA legal name causes an EDD wage-record mismatch and a 7–14 day hold.
- Leaving Line 2 (Today’s Date) blank lets the carrier argue the form was never properly served.
- Using an old mailing address sends Notices of Denial somewhere you no longer live, while the appeal clock keeps running.
- Guessing a date of injury earlier than the §5412 date of knowledge can blow the one-year statute under §5405.
- Listing only the worst body part hands the carrier a free denial of treatment for every other part.
- Forgetting to describe psychiatric symptoms blocks §3208.3 stress-claim benefits.
- Signing without dating the signature lets the carrier dispute when the form was completed.
- Skipping the Notice of Potential Eligibility back page leaves the worker unaware of MPN, predesignation, and §132a rights.
- Failing to keep a date-stamped copy makes it impossible to prove the receipt date that controls §5402.
- Filing only with the broker, not the carrier, sends the form into a black hole and loses the 14-day clock.
- Letting the employer fill in the Today’s Date before you sign violates the worker’s certification and is a ground for rescission.
- Believing termination ends the claim — a properly reported injury survives termination under §3600(a)(10).
Do’s and Don’ts
The list below captures the highest-leverage habits seasoned applicants’ attorneys teach every new client.
- Do keep a date-stamped photocopy of every page, because §5402 lives or dies on that timestamp.
- Do list every body part that hurts, because adding parts later invites denial.
- Do report the injury verbally the same day, because §5400 notice protects you even before the DWC-1 is signed.
- Do request the Notice of Potential Eligibility in your preferred language, because the carrier owes it under §3550.
- Do ask the adjuster for the claim number in writing, because oral claim numbers vanish.
- Do save every text, email, and voicemail with HR, because they often prove date of knowledge under §5400.
- Don’t sign a blank or incomplete form — the carrier will fill it in unfavorably.
- Don’t use medical jargon you don’t fully understand, because vague entries get reinterpreted against you.
- Don’t rely on the employer to mail the form for you; mail it yourself by certified mail.
- Don’t miss the one-year statute of limitations under §5405, even if the claim was “open” administratively.
- Don’t treat outside the MPN without a written predesignation under §4600.
- Don’t sign a Compromise & Release without reading it; it waives lifetime medical rights.
Pros and Cons of Filing on Your Own vs. With Help
Many California workers file the DWC-1 themselves, and many later regret not getting help. Here is the honest tradeoff.
Pros of filing pro se: – No attorney’s fee, which under Labor Code §4906 is typically 12–15% of the recovery. – Faster start, because there is no consultation queue to clear. – Direct relationship with the adjuster, which can speed simple medical authorizations. – Free help available from the DWC Information & Assistance Unit. – Full control over what gets written on every line of the form.
Cons of filing pro se: – Easy to miss the §5412 date-of-knowledge rule and blow the §5405 statute. – Adjusters routinely lowball permanent disability ratings without pushback. – Workers often miss the MPN-vs-predesignation choice that controls treatment. – Recorded statements are used to build denials, and there is no advocate present. – A Compromise & Release signed pro se waives lifetime medical, often without the worker realizing it.
FAQs
Do I have to be a U.S. citizen to file a DWC-1?
No. Immigration status does not affect workers’ compensation rights in California. Every employee, regardless of status, can file a DWC-1, per Labor Code §3351.
Is there a deadline to file the DWC-1?
Yes. Notice to the employer must occur within 30 days under §5400, and the formal claim under §5405 must be filed within one year of the date of injury or §5412 date of knowledge.
Do I write my maiden name or married name on Line 1?
Yes, use whichever name appears on your current Social Security card, because the carrier cross-checks against SSA records and a mismatch triggers a hold.
Can I leave Line 5 (Time of Injury) blank for cumulative trauma?
No. Write N/A — cumulative. A blank field is treated as an incomplete claim and delays processing.
Do I list every body part on Line 7 even if some hurt only a little?
Yes. List every part that hurts, because adding parts later allows the carrier to deny treatment as untimely.
Is the date on Line 13 (Date Claim Form Received) really that important?
Yes. That date starts the 90-day presumption clock under §5402. Always keep a date-stamped copy proving it.
Can my employer fire me for filing a DWC-1?
No. Retaliation for filing a workers’ comp claim is illegal under Labor Code §132a and exposes the employer to penalties up to $10,000 plus reinstatement.
Do I need a lawyer to fill out the DWC-1?
No. The DWC-1 itself is designed for self-completion, but most workers benefit from consulting a certified workers’ comp specialist before signing any settlement.
Is the DWC-1 the same as the WCAB Application for Adjudication?
No. The DWC-1 opens the claim with the carrier; the Application for Adjudication is filed later with the WCAB through EAMS only when there is a dispute.
Can I file a DWC-1 after I am fired?
Yes, if you reported the injury before termination, or if cumulative trauma rules under §3600(a)(10) apply.
Do COVID-19 illnesses get filed on the DWC-1?
Yes. California’s SB 1159 presumption for certain workers is filed on the same DWC-1, with COVID-19 listed as the injury on Line 7.
Can I file a DWC-1 for a psychiatric injury alone?
Yes, but you must have at least six months of employment and meet the predominant-cause standard under §3208.3.
What if my employer refuses to give me a DWC-1?
Yes, you can download the form from the DWC site and serve it yourself by certified mail; the employer’s refusal is itself a §132a and §5814 violation.
Do I need to file a separate DWC-1 for each body part?
No. One DWC-1 covers every body part injured in the same incident or cumulative-trauma period; just list them all on Line 7.
Is there a fee to file the DWC-1 or the WCAB Application?
No. California charges no filing fee for the DWC-1 or the WCAB Application for Adjudication of Claim.
