Buddy Letter for a VA Disability Claim: What to Include (2026)

What Is a Buddy Letter?

A buddy letter - formally known as a "Statement in Support of Claim from a Person with Direct Knowledge" - is a written, signed statement from someone who personally observed events, injuries, or symptoms relevant to a veteran's VA disability claim. Under 38 CFR 3.159(a)(2), lay evidence is defined as evidence that does not require specialized medical knowledge and is "provided by a person who has no specialized education, training, or experience." In plain terms: the people who were there when something happened can tell the VA what they saw.

Buddy letters are most often submitted on VA Form 21-10210, which the VA released in 2020 to replace the older 21-4138 for lay/witness statements. The form includes a certification block - signing it attests, under penalty of perjury, that the statement is true and accurate. That certification is what gives the statement evidentiary weight.

Why Buddy Letters Matter in VA Claims

Military service does not always produce a perfect paper trail. Troops routinely tough out injuries, skip sick call to avoid impacting their unit, or have their encounters documented only in a unit logbook that never makes it into the service treatment record. Decades after separation, a veteran may file a claim for a condition with little or no formal record of the triggering event. Buddy letters fill that gap.

The legal foundation for buddy letters was clarified by the Federal Circuit in Buchanan v. Nicholson, 451 F.3d 1331 (Fed. Cir. 2006). The court held that the VA may not reject competent lay testimony simply because it is not corroborated by contemporaneous medical records. A later case, Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007), confirmed that lay witnesses are generally competent to describe symptoms and events they personally observed, even if they are not competent to offer medical diagnoses.

In practical terms, buddy letters can help establish:

• In-service events or stressors that were not formally reported
• Onset of symptoms during service or shortly after separation
• Continuity of symptoms from service to the present day
• Functional impact of a condition on daily life, relationships, or work
• Corroboration of a veteran's own statements

Who Can Write a Buddy Letter

Anyone with personal, firsthand knowledge of relevant facts can submit a buddy letter. Common sources include:

• Fellow service members who witnessed an injury, event, or stressor during service
• Commanders, NCOs, or unit leaders who can speak to duty assignments, exposures, or incidents
• Spouses and partners who observed symptoms, mood changes, or functional decline over time
• Parents, siblings, and adult children who noticed a change after the veteran's service
• Friends and roommates present at or after key events
• Coworkers or supervisors who saw the impact on work performance
• Clergy, counselors, or community members with observed interactions

There is no requirement that the author hold a particular rank, role, or credential. What matters is whether they personally observed the facts they are describing. A statement that says "I heard from someone else that..." is hearsay and carries much less weight.

What to Include in a Buddy Letter

A strong buddy letter is specific, firsthand, and focused on facts the writer personally observed. The best structure typically includes:

Identification and Relationship

Begin with the writer's full name, address, and phone number. Identify the relationship to the veteran - "I served with SSgt. Smith in 2nd Platoon, Alpha Company, from 2008 to 2010" or "I am SSgt. Smith's wife and have known him since 2005."

Basis for Knowledge

Explain how the writer knows what they are about to describe. Did they witness the event directly? Serve in the same unit? Share a barracks? Observe symptoms over the years after service? Establishing the basis for knowledge is what makes the statement "competent" lay evidence.

Specific Facts Observed

Describe the events or symptoms with as much specificity as memory allows - approximate dates, locations, and what was directly observed. Good examples:

• "On or about March 2009, during a convoy near Baghdad, an IED detonated roughly 15 meters from our vehicle. I was in the lead Humvee and saw SSgt. Smith's vehicle rock violently. When we linked up afterward, he was complaining of ringing in his ears and headaches."
• "Since returning from deployment in 2010, I have watched my husband struggle with sleep. He wakes multiple times per night, paces the house, and avoids crowded stores. Before deployment, he slept soundly and enjoyed family outings."

Concrete, observable detail is what distinguishes a persuasive buddy letter from a generic statement. Vague language like "he always had issues" carries far less weight than a described incident or behavior.

Timeline and Continuity

Where relevant, describe when symptoms began and how they have persisted or worsened. Continuity-of-symptoms evidence is especially useful for chronic conditions that developed during service but were not formally documented until years later.

Certification and Signature

VA Form 21-10210 includes the required certification language ("I certify and declare under penalty of perjury..."). The writer signs and dates the statement. No notary is required.

Common Mistakes to Avoid

Even well-intentioned buddy letters can lose value if they fall into common traps:

• Offering medical diagnoses - stick to observable symptoms and events; leave diagnosis to clinicians
• Relying on hearsay - if the writer did not personally observe it, it should generally not be in the statement
• Generic, non-specific language - "he had a hard time" is far weaker than a described incident
• Arguing the law - buddy letters are factual, not legal briefs; the writer should not argue which regulations apply
• Embellishing or exaggerating - credibility is the most important attribute of a lay statement
• Omitting the basis for knowledge - always explain how the writer came to observe the facts
• Forgetting the certification and signature - an unsigned statement is not evidence

Using VA Form 21-10210

VA Form 21-10210, "Lay/Witness Statement," is the current standard form for buddy letters. The form includes fields for:

• The claimant (veteran) identification - name, SSN or file number, date of birth
• The witness identification - name, address, email, phone
• The relationship between the witness and the claimant
• The written statement itself (with space to attach additional pages as needed)
• The certification, signature, and date

The form is available on VA.gov and can be completed digitally or printed and completed by hand. Longer statements should be continued on plain paper attached to the form, with each attached page signed and dated.

Situations Where Buddy Letters Help Most

Buddy letters are most impactful when they address gaps in the documentary record or supply context the VA cannot otherwise obtain. Particularly high-value scenarios include:

PTSD and Stressor Verification

For non-combat-related PTSD stressors, the VA often requires corroboration. Fellow service members who witnessed the stressor event - a training accident, a sexual assault aftermath, exposure to casualties, a mass-casualty response - can provide the corroboration required under 38 CFR 3.304(f).

Military Sexual Trauma (MST)

Because MST is frequently underreported at the time, buddy letters from anyone who observed behavioral changes, disclosures, or medical visits after the event can help establish the occurrence under the flexible evidentiary rules in 38 CFR 3.304(f)(5).

Undocumented In-Service Injuries

Veterans who toughed out orthopedic injuries or minor TBIs without reporting them may have no entry in the service treatment record. A unit member who saw the fall, the blast, or the vehicle accident can fill that gap.

Exposure-Based Claims

For burn pit, asbestos, herbicide, or contaminated water exposure claims, unit members can confirm the nature and duration of exposure, the location of the hazard, and the veteran's proximity.

Continuity of Symptoms

For chronic conditions like back pain, tinnitus, migraines, or sleep disturbances, statements from family members describing how symptoms have persisted since separation can be decisive.

How to Submit a Buddy Letter

Completed buddy letters can be submitted to the VA several ways:

• Uploaded through VA.gov as an attachment to a pending claim
• Mailed to the Department of Veterans Affairs Claims Intake Center in Janesville, Wisconsin
• Faxed to the VA's designated claims fax number
• Submitted through a VSO or accredited representative who will file it with the claim

Buddy letters can be submitted with an initial claim, alongside a supplemental claim under VA Form 20-0995, or at any other stage of the claims process while the record is open. For Board appeals under the Evidence Submission docket, new lay evidence can be added within the 90-day window after the VA Form 10182 is filed.
