VA Buddy Letter: Proving A Service Connection (2026)

What Is a VA Buddy Letter?

A VA buddy letter is a certified declaration from a lay witness about their observations. This is called a “buddy” letter because the witness usually testifies about the incident that caused your injury or condition. The term “lay witness” simply means that the witness writes about their observations rather than giving their opinions.

How Buddy Letters Strengthen a Claim

Disability claims must include evidence connecting your condition to your military service. The nature of the proof varies for different VA service connection types. However, direct, presumptive and aggravation service connections may require some proof that your military activities produced your injury or illness.

You can use other evidence, such as your declaration or your service records. However, your declaration might be viewed skeptically, and your service records likely lack the details needed by the VA.

Who Can Write a Buddy Letter?

Any person who witnessed the incident can write a buddy letter. Keep in mind that “witnessed” includes anyone who saw, heard or even smelled anything relevant to your VA claims.

You can also submit a buddy letter from anyone who saw or heard anything after the incident, if it is relevant to your claim. For example, a witness could describe seeing you unconscious after an accident to support your brain injury claim, even if they did not see the actual incident.

Note that the witness does not have to be a service member. Doctors, paramedics or anyone else outside the service can be a witness. If the witness is a service member, they can be a stranger or a friend.

What to Include in Your Statement

The statement should include the witness’s recollection of their observations. It should also explain how the witness was able to observe the incident or its aftermath. For example, the witness could state that they were behind your vehicle when they saw it run off the road and crash.

How to Structure the Letter

Your witness should use the VA’s Form 21-10210 for the statement. Your own personal statement, by contrast, goes on VA Form 21-4138. The narrative portion of the form can be written in any way. However, readability is important, so the language should be clear and use minimal military slang, abbreviations and acronyms that might confuse the reader.

Common Mistakes to Avoid

Here are some common pitfalls in VA buddy letters to watch for:

• Including something the witness could not have observed
• Contradicting the claimant’s statement, service records or medical records
• Providing false statements

Stated differently, your witness can avoid harming your claim by sticking to the facts and telling the truth.

How to Submit Your Buddy Letter

You can submit a lay witness statement online at the VA’s website or by mailing it to the VA’s Evidence Intake Center.

A clear and detailed buddy letter can go a long way in helping support your VA claim.
