Evidence FAQ
What evidence do I need for a VA disability claim?
Every VA disability claim requires three elements under 38 CFR § 3.303: (1) a current diagnosis from a licensed provider, (2) evidence of an in-service event, injury, or disease, and (3) a medical nexus opinion linking the current condition to service. Without all three, your claim will likely be denied.
What is a nexus letter and do I need one?
A nexus letter is a medical opinion stating your condition is "at least as likely as not" (50% or greater probability) related to service. It is one of the most important pieces of evidence for your claim. While the VA can obtain an opinion during your C&P exam, a private nexus letter from your treating provider often provides stronger, more detailed support.
Who can write a buddy or lay statement?
Anyone who witnessed your symptoms or limitations can write a lay statement: fellow service members, family members, coworkers, friends, or supervisors. Use VA Form 21-10210. The statement should describe specific observations—what they saw, when, and how it affected you. Their relationship to you and how they know this information should be clear.
What is a DBQ and how do I get one?
A Disability Benefits Questionnaire (DBQ) is a standardized form the VA uses to evaluate conditions. Most DBQs are now "restricted" and must be completed by VA examiners during your C&P exam. However, some conditions have public DBQs that any licensed provider can complete. Check the VA DBQ library for current availability.
Can I submit evidence after I file my claim?
Yes, you can submit additional evidence anytime before the VA makes a decision. However, submitting evidence early is better—it prevents delays and ensures the C&P examiner reviews everything. If you receive an evidence request (VA Form 21-4138), respond quickly to avoid delays.
What happens if I miss my C&P exam?
Missing your Compensation & Pension exam without good cause typically results in claim denial. If you cannot attend, contact the VA immediately to reschedule. If you miss it, submit a statement explaining why and request a new exam. Valid reasons include illness, family emergency, or not receiving notification.
