VA Form 21-10210 — Lay/Witness Statement — is the official VA form for submitting buddy letters and lay evidence in support of a disability claim. Introduced in 2021 as the preferred replacement for VA Form 21-4138 for witness statements, it is designed specifically for testimony from people who personally observed a veteran's condition or an in-service event.
What Is VA Form 21-10210?
Lay evidence is testimony from someone who is not a medical professional but who personally witnessed something relevant to a veteran's disability claim. That can be a fellow service member who saw an injury happen, a spouse who has lived with symptoms for years, or a friend who sees how the condition limits daily life.
VA Form 21-10210 is purpose-built for this type of evidence — with dedicated fields for the observer's relationship to the veteran and the nature of their observations. Both 21-10210 and VA Form 21-4138 are accepted, but 21-10210 is now the preferred form for buddy letters and lay statements.
Who Can Submit a Lay Statement
- The veteran themselves — a personal statement about an in-service event or how the condition affects daily life
- Fellow service members — who witnessed an injury, incident, or stressor during service
- Spouses and partners — who have observed symptoms and behavioral changes over time
- Family members — parents, siblings, children who have seen the condition's impact
- Friends, coworkers, neighbors — anyone with firsthand knowledge of the veteran's condition
Why Lay Evidence Matters
Under VA law and the court precedent set in Caluza v. Brown, lay evidence is competent evidence for conditions with observable symptoms. The VA cannot simply dismiss a well-written lay statement. Lay evidence is especially powerful for:
- Establishing continuity of symptoms — showing a condition has been present since service even when medical records have gaps
- Corroborating an in-service event — confirming an injury or stressor that was not officially documented
- Describing functional impact — showing how the condition limits daily life, work, or relationships
What Makes a Strong Lay Statement
The difference between helpful and weak statements comes down to specificity. "He always seemed to be in pain" is far less useful than a concrete, dated observation.
Strong statements include:
- Specific dates and locations — "During our deployment to [location] in [year]…"
- The observer's relationship — how you know the veteran, for how long, in what context
- Concrete observations — not "he seemed hurt" but "I watched him fall and he could not put weight on his left knee for the rest of the week"
- Changes over time — how the condition has evolved or persisted since service
- Impact on daily life — specific examples of limitations

VA Form 21-10210 vs. VA Form 21-4138
- 21-10210 — designed specifically for lay/witness statements with structured fields for the observer's relationship and observations. Use this for buddy letters.
- 21-4138 — a more general "Statement in Support of Claim." Still accepted but better suited for general statements, clarifications, and requests.

Tips for Veterans Writing Their Own Statement
Veterans can use 21-10210 to submit their own personal lay statement. Your account of what happened in service, how your condition developed, and how it affects you today is valuable evidence. Be specific: use dates, locations, and concrete descriptions. Your statement can also explain gaps in service records, describe an undocumented stressor, or clarify why you did not seek treatment immediately after an injury.
