Describe what you actually saw

A fifteen-minute appointment and a test result miss a great deal. A personal or witness statement can fill that in — not with medical conclusions, but with observation.

VA Form 21-10210, Lay/Witness Statement, is the official form. It can be used to support your own claim or another veteran's, and people often call it a buddy statement.

What makes one useful

Who observed what, when, how often, and what changed. Specific beats emphatic.

A veteran might describe when a symptom started, what an episode is like, how often it happens, and what it stops them doing. Someone else — a partner, a colleague, a person who served with you — describes what they personally saw, how they were in a position to see it, and how that changed over time.

Approximate dates are fine when you say they are approximate. "Sometime in the winter of 2011, I think around January" is honest and usable. An invented precise date is neither.

What weakens one

• Borrowing a diagnosis. A witness describing a medical condition they are not qualified to identify undercuts the parts they are qualified to describe.
• Matching someone else's wording. Several statements that read alike look coordinated rather than corroborating.
• Flattening the variation. If some days are manageable and others are not, say so. A claim that every day is the worst day is easy to disbelieve, and the real pattern is usually more persuasive anyway.
• Writing to a threshold. Aiming at a percentage you have read about produces evidence shaped like a rating criterion rather than like a life.

Two rules that protect what you write

Both come from the Federal Circuit, and both are worth knowing because a decision that ignores them is a decision with a legal error in it.

Silence in the medical record is not a reason to disbelieve you. Buchanan v. Nicholson holds that the Board "cannot determine that lay evidence lacks credibility merely because it is unaccompanied by contemporaneous medical evidence." It can weigh that absence; it cannot make it the answer.

You can be competent to say more than you think. Jandreau v. Nicholson sets out three situations where what a layperson says establishes a diagnosis — where the condition is one a layperson can identify, where you are reporting what a doctor told you at the time, or where symptoms you describe support a later diagnosis by a professional. The third is the one most often overlooked, and it is the one that makes the statement above worth writing.

Neither case makes a statement binding. Both stop it from being set aside for the wrong reason.

Afterwards

Keep a copy and proof of submission, and check it was associated with the right issue. See how records differ — a document in a clinic file is not necessarily in the claim file.
