Lay evidence

Lay evidence is testimony from people who are not medical professionals: written statements from the veteran, family members, friends, coworkers, or people they served with. In a VA disability claim it usually takes the form of a statement describing what the writer personally observed, from symptoms and flare-ups to changes in someone after service.

Lay evidence is competent to describe what an ordinary person can observe: pain behavior, limping, sleep problems, memory lapses, the tasks someone can no longer do. Establishing a diagnosis requires clinical qualifications, so lay statements work alongside the medical record rather than substituting for it.

The VA accepts lay statements on VA Form 21-10210 or in other written form, and it considers them with the rest of the file. Their weight rises when they are first-hand, specific, and consistent with what the clinical record shows.
