A strong buddy letter for a VA disability claim is a signed, dated, firsthand account of what you have personally seen the veteran experience, written in specific and honest detail rather than general praise or sympathy. You can write it as a plain letter or on VA Form 21-10210 (the Lay/Witness Statement). Either format works, as long as it identifies the veteran, describes what you have observed, and carries your signature.
What the Letter Has to Contain
Start with identifying information at the top: the veteran’s full name and VA file number if you know it, then your own full name, your relationship to the veteran, your phone number, and your email address.1Department of Veterans Affairs. VA Form 21-10210 – Lay/Witness Statement Including the file number is what gets your letter matched to the right claim.
The body of the letter is what matters. VA Form 21-10210 instructs the writer to “describe what you yourself know or have observed about the facts or circumstances relevant to this claim.”1Department of Veterans Affairs. VA Form 21-10210 – Lay/Witness Statement That is the entire assignment. Everything strong about a buddy letter comes from taking that instruction literally.
Cover four things:
- Dates or timeframes. When did you first notice the condition or the symptoms? How long have you been observing them? “Since approximately March 2019” is far more useful than “for a long time.”
- Specific behaviors and limitations. Write what you have actually watched happen. “He cannot bend down to tie his shoes without grabbing the counter” is evidence. “He has trouble with daily tasks” is not.
- Changes over time. If the condition has worsened, describe what the veteran could do before and what they struggle with now. The contrast itself is powerful.
- Impact on work and relationships. Missed work, a job lost, withdrawing from family, no longer socializing. Concrete examples.
If you are corroborating something that happened during service rather than describing current symptoms, narrow your account to what you personally witnessed: where you were, what the circumstances were, and what you saw at the time or immediately afterward. Federal regulations recognize this kind of firsthand account as competent lay evidence, and adjudicators are directed to consider it alongside medical records.2eCFR. Title 38 CFR Section 3.303
Mistakes That Get a Letter Discounted
The most common weakness is vagueness. “He is in a lot of pain” or “her condition is really bad” gives a reviewer nothing to work with. Adjudicators are reading through stacks of claims and need specific, observable details that separate this veteran’s situation from a generic description of suffering.
The second is trying to play doctor. A buddy letter is lay evidence. The moment you write “I believe he has a 70% disability” or “her PTSD is clearly caused by the incident on deployment,” you have stepped outside what a non-expert can observe and given the adjudicator a reason to set the whole letter aside. Describe what you see. Leave the diagnosis and the causation to the medical professionals.
Exaggeration backfires. If you claim the veteran “cannot walk at all” but the medical file shows they walked into the C&P exam, the letter loses credibility on everything else. Measured, accurate descriptions are more persuasive than dramatic ones. Saying the veteran struggles to walk more than a block, or needs a cane on bad days, holds up.
Finally, skip the character reference. “He is a great person and deserves this benefit” is not relevant to what the VA is deciding. The claim turns on whether the condition is service-connected and how severe it is, not whether the veteran is likable.
Format, Signature, and Notarization
Type the letter if you can. Handwritten letters are accepted, but hard-to-read handwriting can cause your observations to be missed entirely. Use plain, direct sentences. The reader is a government employee processing a workload of claims.
The letter has to be signed and dated. That is a requirement, not a formality. VA Form 21-10210 includes a certification statement: “I certify that I have completed this statement and that its information is true and correct to the best of my knowledge and belief.”1Department of Veterans Affairs. VA Form 21-10210 – Lay/Witness Statement If you write a standalone letter instead of using the form, include a similar closing statement above your signature.
Notarization is not required. Some veterans and representatives prefer it for the added formality, but a notarized letter and an unnotarized one carry the same legal standing as lay evidence.
Who Can Write One
Anyone with direct, personal knowledge of the veteran’s condition or service can write a buddy letter. The VA specifically points to fellow service members who witnessed an event, injury, or the onset of symptoms; family and close friends who have observed daily life over time; clergy the veteran has confided in; and law enforcement officers who have interacted with the veteran in situations tied to the condition.3Veterans Affairs. Upload Evidence to Support Your Disability Claim Employers and coworkers who have seen the veteran struggle at work can write one too.
No medical training or legal background is required. Your credibility comes from what you have personally observed. A spouse describing years of watching a back injury worsen is providing exactly the kind of evidence the medical file usually cannot.
How and When to Submit It
Once the letter is written and signed, the veteran can upload it through VA.gov using the claim status tool. The VA also directs users to the QuickSubmit tool through AccessVA for other document types.3Veterans Affairs. Upload Evidence to Support Your Disability Claim Mail is another option:

Dropping it off in person at a VA regional office also works. Whichever method you use, make sure the veteran’s full name and VA file number are on the document so it reaches the right file.
Timing matters more than most people realize. You have up to one year from the date the VA receives the claim to submit supporting evidence, but if the VA does not receive information it needs within 30 days, it can go ahead and decide the claim on what is already in the file.3Veterans Affairs. Upload Evidence to Support Your Disability Claim The letter can still be submitted after an early decision, within that one-year window, but the strongest move is to send it in with the initial claim so a reviewer sees it before deciding anything.
