The Human Story: Lay Evidence
Your voice is evidence. Here's how to translate your service into language the VA understands.
Why Lay Evidence Matters
You have your service records (Step 03). They show dates, duty stations, maybe a sick call visit or two. But they don't tell the full story.
They don't explain what it felt like to carry 80 pounds of gear on patrol every day for a year. They don't describe the mental toll. They don't show how your back pain makes you miss your kid's baseball games.
The VA Rater has to consider "Lay Evidence" (your story and witness statements) just as seriously as medical evidence, as long as it describes things you can see, hear, or feel.
Which Form Do I Use?
Personal Statement (VA Form 21-4138)
Use this when YOU are writing about yourself. Describe your symptoms and your in-service event.
Download FormBuddy Letter (VA Form 21-10210)
Use this when SOMEONE ELSE (spouse, friends, service members, co-workers) is writing about you. They act as your eyewitness.

1. The Before: "I was healthy when I joined. Played sports, no issues."
2. The Event: "In 2014, I fell off a truck. Went to sick call, took 800mg Motrin, kept working."
3. The Now: "Today, I miss work 2 days a month because my back locks up. I can't lift my kids."
✅ Example: Strong Lay Statement
Before: “I joined the Army in 2005 with no knee problems. I ran track in high school and passed all physical requirements.”
Event: “During a training exercise in 2007, I landed wrong coming off a wall and felt my knee pop. I went to sick call the next day. They gave me 800mg Motrin and told me to ice it. I continued training because I didn't want to be seen as weak.”
Now: “Today, my knee swells up after standing for more than 30 minutes. I can't run anymore. I have trouble going up stairs. On bad days, I limp.”
🎯 Speak Their Language — From One Veteran to Another
Most VA claim managers were never in the military. They don't know your job, your unit culture, or what your day-to-day life actually looked like in uniform.
Don't assume they understand what your MOS/Job Code duties were, how often you carried weight, bent, knelt, jumped, or stood watch.
You have to spell it out in plain language. Explain what a normal day looked like, the physical and mental strain, and how doing the same tasks over and over broke you down over time.
Buddy Letter Tips
- •Get buddy letters from people who served with you and witnessed the injury or event
- •Spouses can describe how your condition affects your daily life
- •Co-workers today can observe how your condition affects your work
- •Multiple buddy letters from different people strengthen your case
Common Mistakes to Avoid
❌ Bad: “My knee hurts a lot.”
✅ Good: “My knee pain is a 7 out of 10 most days. It prevents me from standing for more than 30 minutes without needing to sit down.”
❌ Bad: “I have PTSD.”
✅ Good: “I was deployed to Iraq in 2007. I was in a convoy that was hit by an IED. Since then, I have nightmares 3-4 times a week, avoid crowds, and can't handle loud noises.”
Pro Tip
Keep your statement under 2 pages. Raters have hundreds of claims to review. Make yours easy to read.
