What it is
VA Form 21-4138 is the Statement in Support of Claim. It is a blank statement form the VA accepts as written evidence in any pending claim. You use it for your own narrative; a separate witness uses it (or VA Form 21-10210) to write a buddy statement on your behalf.
When you use it
File a 4138 when you need to explain something a checkbox form cannot capture: how a stressor unfolded, when symptoms first appeared, how a condition limits work or sleep, or why you are late returning evidence. Buddies, spouses, fellow service members, and supervisors use it to corroborate what they personally saw or heard.
What to gather before you fill it out
Your file number or SSN, the specific claim or condition the statement supports, dates and locations, names of units or providers, and any documents the statement refers to. For lay statements from others, the writer's full name, relationship to you, and signature.
How to submit
Upload through VA.gov, mail to the Evidence Intake Center in Janesville, WI, fax to the number listed on the form, or hand it to an accredited representative. Keep a copy.
Common pitfalls
- Writing opinions a layperson cannot give (medical diagnoses, nexus opinions). Fix: stick to what you saw, felt, or did. Per 38 CFR 3.159(a)(2), lay evidence is competent only for facts a non-expert can observe.
- Vague timelines. Fix: anchor every event to a month and year and a location.
- For PTSD stressors, omitting corroborating details. Under 38 CFR 3.304(f), combat and fear-of-hostile-activity stressors can be established by your testimony alone if it is consistent with the circumstances of service.
