Evidence & Records
Gathering the Right Evidence
The three-legged stool: current diagnosis, in-service event, and medical nexus
Evidence is not about volume — it is about hitting the three elements the VA must find. A thousand pages that miss the nexus lose to three pages that nail it.
The Three Elements — Miss One and You Lose
Every direct service-connection claim needs three things: (1) a current, diagnosed disability, (2) evidence of an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two. These are not guidelines — they are legal requirements. Miss any one and the claim fails, no matter how sympathetic the story or how obvious the connection seems.
Secondary claims replace the in-service event with an already service-connected condition, and the nexus must link the new condition to the primary. Presumptive claims replace the nexus with a statutory presumption. But the structure is always: condition + link + trigger.
Types of Evidence and What They Prove
Service Treatment Records (STRs)
Your in-service medical records documenting injuries, treatments, complaints, and diagnoses during active duty. These are the strongest evidence of an in-service event. If they are missing, the VA has a heightened duty to assist under O'Hare v. Derwinski.
Service Personnel Records
Your 201 file, deployment orders, MOS assignment, duty stations, awards, and disciplinary records. Used to corroborate locations, dates, and duties relevant to the claimed exposure or event.
VA and Private Medical Records
Current treatment records that establish a diagnosed disability and document ongoing severity. The VA is required to obtain VA records and, with your authorization, identified private records under §3.159(c).
Nexus Letter
A written medical opinion from a qualified provider stating that your condition is "at least as likely as not" related to service (or to a service-connected condition). The "at least as likely as not" standard maps directly to the VA's benefit-of-the-doubt rule (§3.102). A strong nexus letter explains the reasoning, cites the medical literature, and addresses contrary evidence.
Lay Statements
Under §3.159(a)(2), you are competent to describe what you experienced and observed: pain, limitation, onset of symptoms, and functional impact. Buddy statements from fellow service members and family are equally valid lay evidence.
Diagnostic and Clinical Evidence
Lab results, imaging studies (MRI, X-ray, CT), psychological testing (PCL-5 scores), and pulmonary function tests. Objective clinical evidence is often the hardest for the VA to discount.
Quality Over Quantity
The VA is not persuaded by the size of a file. It is persuaded by evidence that satisfies each legal element. A 2,000-page records dump that does not contain a nexus opinion loses to a 10-page submission with a current diagnosis, a clear in-service event, and a well-reasoned nexus letter.
Our forensic review identifies which element your claim is missing and gets the specific evidence that fills the gap — nothing more, nothing less.
The Duty to Assist — And Its Limits
Under §3.159(c), the VA has a legal obligation to help you gather evidence: obtaining service records, VA treatment records, and scheduling exams. But this duty has limits. The VA will not search for records you have not identified. It will not write your personal statement. And if you fail to cooperate, the duty can be suspended entirely.
Think of the duty to assist as a matching obligation: you identify and authorize, the VA obtains. The more precise your identification, the more the VA is required to do.
The Advocate's Take
Do not bury the rater. Give them the three things they are required to find, and make each one impossible to ignore. Volume impresses no one — precision wins claims.
Building a Gathering the Right Evidence Claim That Wins
Every claim stands on three legs. Knock one out and the claim falls over, no matter how bad your symptoms are. Before you file, look at your file and find all three.
A current diagnosis
A doctor has to say you have it, now, in writing. Not "reports symptoms of" — a diagnosis. Without this leg, nothing else in the file matters.
A link to your service
An event, an injury, an exposure, or an already service-connected condition. Service records, unit records, buddy statements, and your own account all count as evidence.
A nexus that ties the two together
A medical opinion stating it is at least as likely as not that your service caused or aggravated the condition. That phrase is a legal standard: 50 percent or better. It is the leg most denials break.
Document the problem before you file
• Keep a dated symptom log for at least 30 days. Frequency, severity, and what it stopped you from doing.
• Get statements from people who see it — a spouse, a coworker, a battle buddy. Lay evidence is legal evidence.
• Pull your private treatment records. The VA only has to help; it does not have to go find everything.
• Write down what you have stopped doing. Lost work, lost sleep, lost activities. That is what impairment looks like on paper.
Your Rights in This Process
It costs nothing to file
Filing a VA claim is free. Accredited representatives may only charge for work on an appeal after an initial decision, and those fees are capped by 38 CFR §14.636.
The VA has a Duty to Assist you
Under 38 CFR §3.159 the VA must help you get the evidence it needs, and it must tell you what is missing before it denies you for missing it.
You can ask for a different examiner
You may request a trauma-informed clinician, or a clinician of a specific gender, for a C&P examination. Ask before the exam is scheduled.
You can claim every condition you have
There is no limit and no penalty. Primary conditions, secondary conditions, and conditions made worse by service all get filed.
You can appeal and be re-evaluated
A denial is not the end. You may submit new evidence, request a higher-level review, appeal to the Board, and ask for re-evaluation when your condition worsens.
You must be considered for TDIU
If your service-connected conditions keep you from holding substantially gainful employment, you may be paid at the 100 percent rate without a 100 percent rating.
When You Are Ready to File
Talk to an accredited representative before you file. It costs nothing to ask, and the order you file in changes what the VA is allowed to award you. Albert L. Thombs Jr. is VA-Accredited Claims Agent #45147.
The application itself
This is the form that opens a disability compensation claim. List every condition you are claiming, and name the secondary conditions explicitly.

Lay or buddy statement
The official form for your own statement and for statements from people who witnessed the event or the change in you.
