How to Document Your Injury: Evidence That Wins Cases
Workers' compensation cases live or die on documentation. Strong evidence transforms questionable claims into six-figure settlements. Poor documentation—even for serious injuries—can result in denials and minimal payouts. This guide shows you exactly what to collect and how to use it.
Why Documentation Matters
Here's the hard truth: insurance companies don't believe you. They assume every claim is exaggerated or fraudulent until proven otherwise. Your job is to prove your injury is real, work-related, and as severe as you claim.
Good documentation accomplishes three critical goals:
- Proves the injury happened at work (establishes compensability)
- Demonstrates the severity (maximizes settlement value)
- Creates a timeline (prevents insurance companies from rewriting history)
Let's break down exactly what evidence you need and how to collect it properly.
Immediate Documentation: The First 24 Hours
The clock starts ticking the moment you're injured. Take these steps immediately:
1. Report to Your Supervisor in Writing
Verbal reports aren't enough. Send an email or text message to your supervisor stating:
- The date and time of the injury
- Where it happened (specific location on work premises)
- What you were doing (job task being performed)
- How it happened (brief description)
- What hurts (body parts affected)
Example Email/Text:
"Hi [Supervisor Name], I'm reporting a work injury that happened today at 2:30 PM in the warehouse. I was lifting a 50-lb box from the floor to the shelf when I felt sharp pain in my lower back. I can barely move right now and need to see a doctor. Please provide the workers' comp claim form (DWC-1). Thank you."
Why this matters: Written reports create a timestamp. Insurance companies can't later claim you delayed reporting or the injury happened elsewhere.
2. Photograph the Accident Scene
If physically able, take photos immediately:
- The exact location where the injury occurred
- Any hazards (wet floors, broken equipment, missing safety guards)
- The object or equipment involved
- Overall context showing workplace conditions
Use your cell phone with the timestamp feature enabled. Take multiple angles. Don't wait—evidence disappears quickly when employers know there's been an accident.
3. Document Visible Injuries
Photograph any visible signs of injury:
- Bruising, swelling, cuts, or lacerations
- Burns or chemical exposure marks
- Deformities or unusual positioning
- Redness or inflammation
Update photos daily for the first week. Bruising often worsens over 48-72 hours, and progressive documentation strengthens your case.
4. Get Witness Information
If anyone saw the accident happen:
- Get their full name, phone number, and email
- Ask them to write down what they saw while memory is fresh
- Don't rely on promises like "I'll tell them what happened"—people forget, quit, or get pressured by employers
Text yourself witness contact information immediately. Save those texts permanently.
Medical Documentation: Building Your Case
Medical records are the foundation of every workers' comp claim. Here's how to maximize their value:
1. Seek Treatment Immediately
Don't "tough it out" or wait to see if you feel better. Insurance companies interpret delayed treatment as proof the injury wasn't serious. Get evaluated within 24 hours, even if it's just urgent care or your primary doctor.
2. Be Specific and Detailed with Doctors
When describing your injury to medical providers:
- Don't minimize: Describe your worst pain, not your average day
- Be specific about location: "Sharp pain in my lower left back radiating to my left leg" beats "my back hurts"
- Quantify pain: Use the 1-10 scale consistently
- Explain functional impact: "I can't lift my arm above shoulder height" is better than "my shoulder hurts"
- State it's work-related: Always mention the injury happened at work
Critical Mistake to Avoid:
Never tell a doctor "I'm fine" or "I'm feeling better" if you're not. Doctors write what you say. If records show "patient reports feeling well," insurance companies will use that against you forever. Be honest about your limitations.
3. Keep a Pain Journal
Starting the day of your injury, maintain a daily log documenting:
- Pain levels (1-10 scale) at different times of day
- Activities you can't do (lifting kids, sleeping through night, getting dressed)
- Medications taken and their effectiveness
- Medical appointments attended
- Work days missed
- How the injury affects your daily life
This journal becomes powerful evidence at settlement negotiations and hearings. It's hard to dispute contemporaneous notes.
Sample Pain Journal Entry:
March 15, 2026
Morning pain: 7/10 in lower back
Couldn't tie my shoes - wife had to help
Took 2 ibuprofen at 8am, minimal relief
Physical therapy at 10am - exercises made pain worse
Afternoon pain: 9/10
Can't sit for more than 20 minutes
Couldn't pick up my daughter (28 lbs)
Slept only 3 hours due to pain
4. Request Complete Medical Records
Don't rely on the insurance company to get your records. Request copies yourself from:
- Emergency room visits
- Primary treating physician
- Specialists (orthopedists, neurologists, pain management)
- Physical therapists
- Imaging centers (X-rays, MRIs, CT scans)
Review records for errors. Doctors sometimes transcribe wrong information. If you find mistakes, request amendments in writing.

Workplace Documentation
1. Incident Reports
Your employer should complete an incident report. Demand a copy. Review it carefully for inaccuracies. If the report minimizes the accident or contains false statements, write a rebuttal and attach it.
2. Safety Violation Evidence
If your injury resulted from safety violations, document:
- Missing or broken safety equipment
- Lack of training or warnings
- Unsafe work practices your supervisor ordered
- Previous complaints about the hazard
- OSHA violations (if Cal/OSHA inspected)
This evidence is gold. It proves employer negligence and strengthens your case significantly.
3. Job Description and Physical Demands
Obtain your official job description showing:
- Physical requirements (lifting, standing, repetitive motions)
- Typical tasks performed
- Equipment used
- Work schedule and hours
This proves the injury relates to your job duties. It also establishes you can't return to work if permanent restrictions exceed job requirements.
4. Wage Documentation
Collect evidence of your earnings:
- Recent pay stubs (at least 3 months before injury)
- Tax returns (W-2s or 1099s)
- Overtime records
- Bonus or commission statements
Your temporary and permanent disability benefits are calculated from your average weekly wage. Higher documented wages = higher benefits.
Communication Documentation
1. Save All Emails and Texts
Create a dedicated folder for workers' comp communications:
- Emails with your supervisor about the injury
- Messages with the insurance adjuster
- Texts about medical appointments
- Any communication about your claim
Never delete anything. What seems insignificant now may be crucial later.
2. Document Phone Calls
After every phone call with the adjuster, doctor's office, or employer, send yourself an email summarizing:
- Date and time of call
- Who you spoke with
- What was discussed
- What was promised or agreed to
- Any deadlines mentioned
This creates a written record of verbal conversations that might otherwise be denied.
3. Keep a Claims Timeline
Maintain a chronological record of all claim-related events:
- Injury date
- Report to supervisor date
- DWC-1 form received date
- First medical treatment date
- When temporary disability started/stopped
- Claim acceptance or denial dates
- Settlement offers received
This timeline becomes essential if you need to prove delays or bad faith by the insurance company.
Financial Documentation
Track the financial impact of your injury:
1. Lost Wages
- Days of work missed
- Reduced hours due to injury
- Lost overtime opportunities
- Missed promotions or raises
2. Out-of-Pocket Expenses
Keep receipts for:
- Medications not covered by workers' comp
- Mileage to medical appointments
- Medical equipment (back braces, ice packs, cushions)
- Home modifications (grab bars, shower seats)
Some expenses may be reimbursable. Even if not, they demonstrate the injury's impact.
Video Documentation
For certain injuries, video evidence is extremely powerful:
Range of Motion Limitations
Record yourself attempting normal movements that cause pain:
- Reaching overhead (shoulder injuries)
- Bending forward/backward (back injuries)
- Walking or climbing stairs (leg/knee injuries)
- Gripping objects (hand/wrist injuries)
Daily Function Struggles
Show how the injury affects routine tasks:
- Getting dressed
- Getting in/out of a car
- Lifting grocery bags
- Playing with your children
Short clips (30-60 seconds) are sufficient. Date-stamp everything.
What NOT to Document
Be careful what you create and share:
Social Media Posts
Don't post about your injury, your case, or activities on Facebook, Instagram, Twitter, etc. Insurance companies monitor social media religiously. Even innocent posts can be twisted.
Social Media Mistakes That Kill Cases:
- Photos of physical activities (hiking, sports, yard work)
- Check-ins at gyms or sporting events
- Posts about "feeling great" or "having a good day"
- Pictures showing you without visible pain or limitations
Exaggerations or Lies
Never document anything that isn't 100% true. If you claim you can't lift 10 pounds, don't let surveillance catch you carrying a case of water. Dishonesty destroys credibility and can result in criminal fraud charges.

- Communications: Emails, texts, call summaries
- Financial: Pay stubs, expense receipts, wage loss calculations
- Photos/Videos: Organized by date
- Legal Documents: Claim forms, settlement offers, hearing notices
Keep multiple backups. Cloud storage (Google Drive, Dropbox) ensures you don't lose everything if your computer crashes.
How Attorneys Use Your Documentation
When you hire a workers' comp lawyer, strong documentation allows us to:
1. Prove Liability Quickly
Clear evidence of a work-related injury speeds up the claims process and reduces the chance of denial.
2. Maximize Medical Evidence
We coordinate with your doctors to ensure medical reports accurately reflect your condition and work-relatedness. Your pain journal and photos help doctors write better reports.
3. Calculate True Value
Wage documentation, expense records, and functional limitations help us determine the full value of your claim—not just what the insurance company offers.
4. Negotiate Aggressively
Well-documented cases give us leverage. Insurance adjusters know we can prove our case at trial, which increases settlement offers.
5. Win at Hearings
If your case goes before a Workers' Compensation Judge, documentation is everything. We present your evidence in a compelling narrative that wins benefits.

Frequently Asked Questions
What if I didn't document the injury right away?
Start now. While immediate documentation is ideal, you can still build a strong case by gathering evidence currently available: medical records, witness statements (even delayed), job descriptions, and going-forward pain journals. Consult an attorney to help fill gaps.
Can the insurance company demand to see my personal medical records?
They can request records related to the injured body part. They can't access your entire medical history without authorization. Be careful what you sign—never agree to blanket medical releases. Your attorney can negotiate appropriate record disclosure.
Should I keep documenting after my claim is accepted?
Yes. Ongoing documentation proves the injury's lasting impact and supports your permanent disability rating. Keep your pain journal going, attend all medical appointments, and document functional limitations until your case settles.
What if my employer refuses to give me a DWC-1 form?
They're legally required to provide it within one business day. Document the refusal (email your supervisor requesting it). You can download the DWC-1 yourself from California's Division of Workers' Compensation website. File it directly with your employer's insurance carrier (listed on workplace posters). Report the employer's violation to the DWC.
The Bottom Line
Workers' compensation claims are won or lost based on evidence. Insurance companies count on injured workers being too overwhelmed, too injured, or too uninformed to document properly. Don't let them win by default.
Start documenting immediately. Be thorough, be honest, and be organized. The few hours you spend gathering evidence can be worth tens of thousands of dollars in additional settlement value.
And if you're feeling overwhelmed by the process, that's exactly when you need an attorney. We'll guide you through documentation, obtain evidence you might miss, and use it to build the strongest possible case for maximum compensation.
