Your claim needs more than the claim form gives you room for. Your spouse watched your knees go downhill for ten years. A guy from your unit was there the day it happened. Somebody tells you “just write a 4138.” Somebody else says “get a buddy statement.” Those are two different forms. VA Form 21-4138 is your own statement. VA Form 21-10210 is the lay or witness statement, the one a buddy, spouse, or coworker fills out.
What it actually is
VA Form 21-4138 is the Statement in Support of Claim. The PDF on VA’s site is the July 2024 revision, which replaced the June 2021 version. VA.gov says to use it to share more information as instructed by another VA form or process. The examples VA gives are pretty specific:
- More detail about your family situation or finances for pension, Dependency and Indemnity Compensation, or accrued benefits.
- Telling VA about a reimbursement you got after you already sent in a medical expense report.
- More detail about claimed disabilities or other issues that won’t fit on the original claim form.
The layout is simple. Section I is you: name, SSN, VA file number if you have one, date of birth, service number if it applies, phone, and mailing address. Section II is two pages of blank remarks under one line: “The following statement is made in connection with a claim for benefits in the case of the above-named veteran/beneficiary.” Section III is the signature. Item 9 is the veteran or beneficiary signature, and it’s required. Item 10 is the date.
Notice what’s missing. There is no witness section on the 4138. No witness name, no relationship box, no witness contact info. It’s built for the veteran or beneficiary to explain their own case.
VA Form 21-10210 is the Lay/Witness Statement. VA.gov’s words: use it to submit a formal statement to support your VA claim, or the claim of another Veteran or eligible family member, and “people also sometimes call this statement a buddy statement.” The PDF posted now is also a July 2024 revision.
The 10210 is built around a witness:
- Section I is the veteran.
- Section II is the claimant, and you only fill it in if the claimant is not the veteran, like a surviving spouse.
- Section III, Item 17 is the statement itself. The instruction printed right on the form: “Describe what you yourself know or have observed about the facts or circumstances relevant to this claim before VA.” The form also tells you to name the claimed issue you’re addressing.
- Section IV is witness contact info: name (Item 18), relationship (Item 19: served with the veteran, family or friend, coworker or supervisor, or other), phone, and email.
- Section V is the certification and signature, Item 22A, with the date in 22B.
One more rule on the form: if you have more than one witness, or you want to add another statement of your own, each statement gets its own 21-10210.
Both forms mail to the same place: Department of Veterans Affairs, Evidence Intake Center, P.O. Box 4444, Janesville, WI 53547-4444. Both can be filed online. Both print a penalty warning about fines or prison for knowingly false statements of material fact. So write what’s true and stop there.
Which one to use
Ask one question: who is talking?
If it’s you explaining your own situation, because another form or a VA letter told you to add information, or because your details won’t fit on the claim form, that’s the 4138.
If it’s someone else telling VA what they saw, that’s the 10210. Your spouse, your old squad leader, the coworker who covered your shifts when your back went out. One person per form. The witness writes it and the witness signs it.
You can also use the 10210 for your own statement. Its instructions cover a statement “as a veteran/claimant or someone writing on your behalf.” But the 4138 is still the paper VA names when a form or process asks you for more information.
VA’s Evidence needed for your disability claim page backs all of this up. Lay evidence is written testimony by you or someone who knows about your condition or related events. Anyone can give it. They don’t need special training or education. VA reviews it along with your other evidence. And VA lists three ways to send it: a statement on a blank piece of paper, a 21-10210, or a 21-4138.
So the blank-paper letter isn’t wrong. The forms just put your identifying info, the claimed issue, and the signature where VA expects to find them.
Do this today
- Figure out who’s talking. You explaining your own case: 21-4138. Somebody else telling what they saw: 21-10210, one per person.
- Name the claimed issue at the top of the statement. “Right knee.” “Tinnitus.” “PTSD.” Don’t make the rater guess which claim it’s for.
- Have witnesses write only what they saw or know firsthand. Where they were, about when, what they saw happen, what they’ve noticed since. Dates and places beat adjectives.
- Check the relationship box. On the 10210, Item 19 tells VA how the witness knows you: served with you, family or friend, coworker or supervisor, or other.
- Sign and date it. Item 9 and 10 on the 4138. Item 22A and 22B on the 10210. An unsigned statement is just a letter.
- File online when you can. Use submit a 21-4138 online or submit a 21-10210 online. Screenshot the confirmation.
- If you mail it: Evidence Intake Center, P.O. Box 4444, Janesville, WI 53547-4444. Keep a copy of every page. Certified mail with return receipt is how you prove VA got it.
- If the proof is doctor records instead of a statement, that’s a different form. See 21-4142 vs 21-4142a. The rest of the official list lives on Veteran Resources.
What people get wrong
“A 4138 is a buddy statement.” It’s not. The 4138 has no witness section. VA itself calls the 10210 the buddy statement.
“I’ll write my buddy’s statement and have him sign it.” Item 17 says to describe what you yourself know or observed. The witness writes the witness statement. Your words with his signature help nobody and the penalty warning applies to whoever signs.
“Three buddies can share one 10210.” The form says each witness uses a separate 21-10210. Three people, three forms.
“My wife can’t write one because she’s family.” Item 19 has a box for family or friend. VA’s evidence page says anyone who knows about your condition or related events can provide lay evidence.
“A witness needs medical training for VA to care.” VA says the person doesn’t need any specific training or education. They’re telling VA what they saw, not diagnosing you.
“Longer is better.” The form asks for what the person knows or observed about facts relevant to the claim. A tight page with dates, places, and what changed beats five pages of how great a guy you are.
“I have to mail these.” Both forms have an online option on VA.gov. Mail still works. Online gets you a confirmation screen.
“Forms beat a plain letter every time.” VA lists a statement on a blank piece of paper as one of the three accepted ways to send lay evidence. The forms are tidier, but a signed, specific letter still counts.
Two forms, two jobs. The 4138 is you adding to your own claim. The 10210 is a witness on the record, one per person, signed by the person who saw it. This isn’t legal advice, and a free accredited VSO can look over your statements before you send them. Questions go to Ask VA or 800-827-1000 (TTY 711).
