Statement in Support of Claim
You need to add information, clarify, or respond to a VA letter - and no other specific form fits.
- Who fills it
- veteran
- Journey phase
- Evidence & Statements
- Estimated time
- 20-60 minutes depending on what you're writing.
- When to file
- Anytime during a claim. Many veterans file 21-4138 alongside the initial 21-526EZ to provide a longer narrative explaining service connection.

- ▸Your VA File Number / claim number (from any VA correspondence)
- ▸The specific question or topic you need to address

Section I - Veteran Identification
Blocks 1-5Veteran name, SSN, VA file number, addressPII
Match exactly to your 21-526EZ. Include the VA File Number from any VA letter you have received about this claim - that's how VA cross-files this statement to the right jacket.
(use same details as 21-526EZ; add VA File Number from prior correspondence)
Common mistakes
- ×Omitting the VA File Number - statement gets indexed under your SSN but may not auto-attach to the active claim.
Section II - Statement
Block 8Your statement
Write in your own words. Use clear, factual language. Stick to one topic per statement - if you need to address multiple unrelated issues, file a separate 21-4138 for each. The narrative can be as long as you need; attach extra sheets if the form's space runs out.
e.g., I am writing to clarify the onset date of my lumbar degenerative disc disease. My back pain began in approximately June 2008 during a deployment to Iraq, after I sustained a fall during a foot patrol when carrying 80 lbs of gear...
Common mistakes
- ×Mixing multiple unrelated topics in one statement - file one 21-4138 per topic so VA can route each to the right reviewer.
- ×Editorializing about the VA, the rater, or "the system" - sticks to facts; opinions don't move ratings.
- ×Vague timing ("a long time ago") - give month/year even if approximate.
- ×Restating evidence already in the file - add NEW facts or clarification, don't duplicate.
- ×Forgetting to label attached evidence ("see attached letter from Dr. Smith dated 1/15/2026") so the reviewer can cross-reference.

Section II - Statement (continued)
Block 8 (continued)List of attached documentsRepeatable
Numbered list of every document attached to this statement. Each attachment should be clearly labeled at the top with: your name, SSN, claim number, "Attachment N to VA Form 21-4138 dated MM/DD/YYYY".
e.g., Attachment 1: Letter from Dr. Jane Smith, MD dated 01/15/2026 (3 pages) Attachment 2: Photographs of injury site, undated (2 pages) Attachment 3: Buddy statement from SGT Williams (VA Form 21-10210) (2 pages)
Common mistakes
- ×Submitting attachments without labeling - they get separated from the statement and lost in the file.
- ×Submitting originals instead of copies - VA will not return them.
Section III - Signature
Block 9Signature, date, and certificationPII
Sign and date. By signing, you certify that the statements are true to the best of your knowledge. Knowingly false statements are a federal crime; uncertain memory phrased as such ("approximately", "to the best of my recollection") is fine.
(signature/date when filing)
Common mistakes
- ×Forgetting to date - VA will return for completion.
- ×Signing without reading what you wrote - proof, then sign.
