Ask a witness for one bounded account of what they personally observed. Tell them what issue you are trying to document, then leave the wording and conclusion to them.
The best witness is not always the person closest to you. It is the person who knows the fact the statement needs to establish.
Match the witness to the evidence gap
Use this worksheet:
| Fact to document | Possible witness | Why they know it |
|---|---|---|
| Event during service | Person present at the event | Saw the event or immediate response |
| Change after service | Spouse, relative, or longtime friend | Knew the before-and-after routine |
| Work impact | Coworker or supervisor | Observed tasks, breaks, attendance, or accommodation |
| Nighttime symptoms | Household member | Personally observed sleep behavior |
| Frequency of assistance | Caregiver or family member | Provided the help described |
One witness does not need to cover the entire claim. If you are unsure whether a fact belongs in your own statement or in a witness's, see lay statement vs. buddy statement.
A request script
I am preparing a VA claim about my right knee. You saw me at work during the period when it began limiting my walking and lifting. Would you be willing to write a short statement about what you personally observed, including when you noticed it and one specific example? Please use your own words and leave out anything you do not remember. You do not need to give a medical opinion.
The request identifies the subject, explains why that witness was asked, and sets an honest boundary.
Give prompts, not answers
Useful prompts include:
- How do you know me, and during what period?
- What did you personally see or hear?
- When did you first notice it?
- How often did you observe it?
- What is one event you remember clearly?
- What changed compared with earlier?
- What details are you unsure about?
Do not send a fully written statement and ask the witness to sign it. You can check identity details and point out an unclear date, but the account should remain theirs.
Let the witness decline or narrow the request
Some people will not remember enough. Others may be comfortable describing one event but not a private medical topic. A narrow truthful statement is more useful than a broad statement written out of obligation.
Follow up once, with a clear deadline
Explain when you hope to have the statement and why. A short reminder is reasonable. Repeated pressure can damage the independence of the response.
When the statement arrives, ask the witness to review the final copy, correct any errors, and follow the current signature and submission instructions. VA provides Form 21-10210 and an online statement option. Returning a response to you is not the same as filing it with VA.
Keep observation and medical judgment separate
VA says anyone can provide lay evidence and does not need special training. That does not make every person qualified to diagnose a condition or explain its medical cause. Read VA evidence requirements and 38 C.F.R. § 3.159.
Use a builder or invitation according to the task
On Claim Raven's Buddy Letters page, a witness can use the public builder to draft and download a plain letter without an account. A signed-in veteran can create an invitation, choose a Claim Workspace, track waiting and returned requests, and send a reminder. Invitation management is included with Standard and Plus. The witness does not need a Claim Raven account to respond.
Claim Raven does not file the returned statement with VA. Review, signature, and submission remain separate steps.
For content ideas, use VA buddy letter examples. For the official form, use the 21-10210 completion guide.
