How to write a VA buddy letter or lay statement
A statement from someone who was there is real evidence, and the VA is required to consider it. It works best when it describes what the writer saw, not when it argues the claim.
A VA buddy letter is a lay statement: a written account of facts someone personally knows about your condition, or about an event that matters to your claim. You can also write one about yourself. VA accepts lay evidence on VA Form 21-10210, on VA Form 21-4138, or on plain paper, and reviews it along with the rest of the evidence (VA.gov, evidence needed).
Lay evidence is testimony from someone without medical training: you, your spouse, the person who shared your barracks room, your old squad leader, a coworker. The VA cannot dismiss it just because it did not come from a doctor. Where it is competent and credible, it has to be weighed like any other evidence. It is also easy to misuse, by writing a statement that argues the claim instead of describing what happened. The template and format checklist below show what goes in one.
Buddy statement format and template
VA does not require special wording. On VA Form 21-10210, the person writing fills in Section IV (witness name, relationship to the veteran, telephone number, email), writes the statement in item 17, and signs and dates it in Section V. Each witness uses a separate copy of the form. The veteran's own details go in Section I. A format checklist:
- Who: the writer's full name and how they know the veteran (served with, family or friend, coworker or supervisor, or other).
- How they know: when and where they met or served together, and for how long.
- What they saw or heard: events and symptoms they observed themselves, in plain terms, with no diagnosis and no opinion on the cause.
- When: dates, or the nearest month and year, and the place.
- How often and how long: for symptoms the writer sees now, how often they happen, how long they last, and what the veteran stops doing because of them.
- What changed: how the veteran was before, if the writer knew them then.
- Signature and date: the writer signs and dates it. Item 22A, the signature, is marked required on the form.
- The penalty statement: the form carries VA's warning that the law provides fine or imprisonment, or both, for willfully submitting a false statement of material fact. A statement on plain paper should end with a signed, dated line saying it is true and correct to the best of the writer's knowledge and belief.
A fill-in-the-blanks template for item 17 of VA Form 21-10210. Replace each bracket with the writer's own facts, and delete any line that does not apply.
I am [writer's full name]. I [served with / am the spouse of / am a friend of / worked with] [veteran's full name] and have known [him / her / them] since [month and year], when we [were stationed at / lived in / worked at] [base, city, or employer].
On or about [month and year], at [place], I personally saw [what happened, or what the veteran was doing]. [Describe what you saw, heard, or helped with, and who else was there.]
Since then I have seen [symptom or limitation, for example waking up several nights a week, leaving work early, avoiding crowds] about [how often] and lasting about [how long]. Because of it, [name what the veteran stopped doing or has to do differently].
Before [event or date], [veteran] was [how the veteran was before, if you knew them then].
I certify that this statement is true and correct to the best of my knowledge and belief. [Signature] [Date, MM/DD/YYYY]
What lay evidence can and cannot prove
The line is roughly this: you are competent to describe what you personally observed through your own senses. You are not competent to diagnose a disease or explain its medical cause.
| A lay statement can establish | A lay statement cannot establish |
|---|---|
| Symptoms you felt or a witness saw: pain, ringing, nightmares, stopping breathing in your sleep, a limp. | That you have obstructive sleep apnea rather than another sleep disorder. |
| An event in service: the blast, the fall, the convoy, the injury nobody wrote down. | That the blast caused your current headaches, as a medical conclusion. |
| Continuity: that the symptom started then and never stopped. | The correct diagnostic code or rating percentage. |
| Functional impact: what you can no longer do at work or at home. | A rating criterion that depends on medical testing, such as a range-of-motion measurement or a sleep study result. |
The medical side of the link, what caused the condition, is what a nexus letter supplies. So a buddy letter saying "his back was clearly injured in the fall and it caused his current degenerative disc disease" is doing the one thing it cannot do. The same letter saying "I helped him off the vehicle after he fell, he could not stand up straight for a week, and he was still complaining about his back when we separated in 2011" is doing exactly what it should.
A veteran claims service connection for a left wrist condition the service treatment records never mention. A fellow service member's VA Form 21-10210 makes three points:
- In August 2010, under small-arms fire, the writer saw the veteran jump from a stopped truck to take cover and land hard on an outstretched left hand.
- The wrist swelled badly. The medic splinted it, nobody went to sick call, and the writer watched the veteran work one-handed for the rest of that month.
- That landing caused the chronic wrist pain and arthritis the veteran has now.
The writer saw points 1 and 2, so 38 CFR § 3.159(a)(2) makes the writer competent to report them. Point 3 is a diagnosis and a medical cause, which no witness can observe, so it needs competent medical evidence as § 3.159(a)(1) defines it: a current diagnosis, and a medical opinion linking it to that landing.
If VA finds the veteran engaged in combat with the enemy, 38 U.S.C. § 1154(b) and 38 CFR § 3.304(d) accept satisfactory lay evidence of a combat injury as proof, even with no official record, if consistent with the circumstances of that service. That eases proof of the injury only. A Board decision applying Federal Circuit precedent still requires a current disability and a link to service, though the link can be easier to show when the injury was lasting. Point 3 still needs medical evidence.
The forms
Two VA forms cover this, and VA's own descriptions split them like this.
- VA Form 21-10210, Lay/Witness Statement. VA's form for a formal statement supporting a claim, whether it comes from the veteran or from someone writing on the veteran's behalf, the "buddy statement". Each statement goes on its own copy of the form, and the statement box asks the writer to describe what they personally know or have observed.
- VA Form 21-4138, Statement in Support of Claim. VA's form for adding information when another VA form or process asks for it, including details about claimed disabilities that do not fit on the original claim form.
A statement on plain paper is not ruled out, but 38 CFR § 3.200(b) requires written testimony offered to establish service connection to be certified or made under oath or affirmation. A plain-paper statement should therefore carry the veteran's name and file number and end with a signed, dated line certifying that it is true and correct to the best of the writer's knowledge and belief. Both forms build that certification in and remove any doubt about who wrote the statement and which claim it belongs to. Whoever writes it signs and dates it. To send it in with a new claim, see how to file a VA disability claim.
What makes a statement carry weight
Specific beats emphatic
"His migraines are absolutely debilitating" tells a rater nothing they can use. "He gets one about every ten days. When it starts he goes into the bedroom with the blinds shut, does not come out for the rest of the day, and cannot be spoken to. He has left work early because of it at least six times since March" is evidence a rater can map directly onto rating criteria.
Frequency, duration, and what stopped as a result. Those three carry almost all the weight.
Dates and details prove you were there
Naming the unit, the base, the rough month, the other people present, and what you were doing establishes that the writer actually witnessed the event. A statement with no anchoring detail reads as generic and gets weighed accordingly.
Describe the full range of symptoms
Veterans describe their best functioning almost automatically, out of pride or habit. The rating is meant to reflect the disability picture over time, including flare-ups. Describe the range honestly: what a good week looks like, what a bad week looks like, and how often each happens.
Say what changed
A statement from someone who knew you before and after service is unusually powerful, because it establishes a baseline nobody else can. "He was the one organising everyone before he deployed. Now he will not come to anything with more than four people in the room" is the kind of observation no medical record contains.
Credibility is weighed. Under 38 CFR § 3.102, mere suspicion that a statement is untrue is not a reason to withhold the benefit of the doubt, but the rule sets apart a statement impeached or contradicted by evidence or known facts. So a statement that conflicts with the medical records, or overstates in a way the file disproves, may not get the benefit of the doubt. Describe it accurately and let the criteria do their work.
Where lay statements matter most
- Undocumented in-service events. Some injuries in service were never written down, and records that were made cannot always be found. A buddy statement may be the only surviving evidence. For a veteran who engaged in combat with the enemy during a period of war, campaign, or expedition, 38 U.S.C. § 1154(b) goes further: satisfactory lay evidence that an injury or disease was incurred in that service is accepted as proof of it, even with no official record, as long as it is consistent with the circumstances, conditions, or hardships of that service.
- PTSD stressors. 38 CFR § 3.304(f) generally requires credible supporting evidence that the stressor happened. In a few situations the veteran's own testimony alone can establish it, if consistent with the circumstances of service. Those are PTSD diagnosed during service with a stressor related to that service, and a stressor related to combat or to prisoner-of-war experience. A fear of hostile military or terrorist activity also qualifies when a VA or VA-contracted psychiatrist or psychologist confirms the stressor is adequate to support the diagnosis and that the symptoms are related to it. For a claim based on in-service personal assault, the regulation names statements from family members, roommates, fellow service members, or clergy among the evidence that can corroborate it, including what they noticed about behavior changes afterward. These statements go in alongside VA Form 21-0781.
- Sleep apnea. Someone who slept in the same room and watched you stop breathing, years before any sleep study, is evidence of symptoms back then. It does not diagnose apnea; a medical opinion still has to connect those symptoms to the later diagnosis. See the sleep apnea guide.
- Continuity of symptoms. Where there is a gap in treatment records, statements bridge it: you had the symptom the whole time, you just did not go to a doctor about it.
- Unemployability. Statements from supervisors and coworkers about accommodations, missed days, and performance decline go to the question a TDIU claim turns on under 38 CFR § 4.16: whether service-connected disabilities leave the veteran unable to secure or follow a substantially gainful occupation.
One page is plenty. Three specific paragraphs beat six pages of adjectives, and a rater reading a large file will find the specifics faster in a short document.
Buddy letter and lay statement questions
What is a VA buddy letter or lay statement?
It is a written statement from someone without medical training about facts they personally know, such as an event in service or symptoms they have watched. The writer does not have to be someone you served with: a spouse, relative, friend, coworker, or you yourself can give one. VA treats it as competent lay evidence when it comes from someone who knows the facts and describes things a layperson can observe (38 CFR § 3.159(a)(2)). Buddy letter, buddy statement, and lay statement all mean the same thing here.
Do I need lay statements for my VA claim?
VA does not require one, and a statement does not guarantee an award. VA reviews lay evidence along with the other evidence in the file. Statements help most when they add something the records lack: an injury nobody wrote down, symptoms between treatment visits, or how the condition affects daily life and work (VA.gov, evidence needed).
How do I write a VA buddy statement?
Start with who you are and how you know the veteran, including when and where. Then describe what you personally saw or heard, with dates or the nearest month and year, how often it happens, how long it lasts, and what the veteran can no longer do because of it. Leave out diagnoses and opinions about the cause. End by certifying that the statement is true and correct to the best of your knowledge and belief, then sign and date it. VA Form 21-10210 has a place for each of these, and written testimony offered to establish service connection must be certified or made under oath (38 CFR § 3.200(b); VA Form 21-10210).
Where can I find a buddy letter template and lay statement example?
The fill-in template on this page follows VA Form 21-10210, and the worked example shows how a statement is weighed. A short example: I shared a room with John Doe at Fort Example from June 2010 to May 2011. Most nights I heard him snore loudly, and several times a week I saw him stop breathing and wake up gasping. Every name, place, and date there is invented. Replace the brackets in the template only with things the writer actually saw.
Should I use Form 21-10210 or 21-4138 for a statement in support of claim?
Either works, and so does plain paper: VA accepts lay evidence on a blank page, on VA Form 21-10210 (Lay/Witness Statement, also called a buddy statement), or on VA Form 21-4138 (Statement in Support of Claim). VA describes the 21-10210 as its form for a formal statement supporting a claim, and the 21-4138 as its form for sharing more information when another form or process asks for it, including details about claimed disabilities that do not fit on the claim form (VA.gov, Form 21-4138). A first-person example: Since 2019 my right knee gives way two or three times a month, usually on stairs, and I stopped jogging in 2020. For writing your own, see the personal statement guide.
