VA Form 21-4138, Statement in Support of Claim, is where you add your own written account to a VA benefits claim. To fill it out, complete the identification fields at the top, write your statement in the Remarks section using specific dates, symptoms, and functional limits, then sign and date under penalty of perjury. You can download the PDF free from VA.gov and submit it online, by mail, or in person at a regional office.
One boundary before you start: this form is for your own words about your own claim. If a spouse, fellow service member, coworker, or anyone else wants to submit a statement supporting you, they use VA Form 21-10210, Lay/Witness Statement — sometimes called a buddy statement — and each witness needs a separate copy of that form.
When You’d Submit One
Common reasons to file a 21-4138 include explaining how a disability started or worsened during service, describing symptoms your medical records don’t fully capture, responding to a VA request for more information, or adding context to a supplemental claim. It also supports a request for an increased disability rating by documenting how your condition has gotten worse since your last evaluation.
Section I: Identification Information
The July 2024 version of the form opens with eight identification fields:
- Field 1: your full legal name (first, middle initial, last).
- Field 2: your Social Security number.
- Field 3: your VA file number, if you have one. Leave blank if you don’t.
- Field 4: your date of birth.
- Field 5: your service number, if applicable.
- Field 6: your telephone number with area code.
- Field 7: your email address (optional).
- Field 8: your complete mailing address.
Fields 2 and 3 do the routing work. The VA matches your statement to your electronic claims folder using your Social Security number and VA file number. If either is missing or wrong, the document can sit unassigned instead of reaching the reviewer handling your claim.
Section II: Writing Your Statement
Section II is labeled “Remarks” and gives you roughly half a page of open space. If you need more room, continue on plain paper, put your name and Social Security number at the top of every additional page, number the pages, and note the total so nothing gets separated during processing.
What you write matters more than how much you write. The VA defines competent lay evidence as anything “provided by a person who has knowledge of facts or circumstances and conveys matters that can be observed and described by a lay person.”1eCFR. 38 CFR 3.159 – Department of Veterans Affairs Assistance in Developing Claims You don’t need medical expertise to describe your own symptoms — what you felt, when it started, what makes it worse, and how it limits what you can do.
A vague statement like “my back hurts and it’s hard to work” gives a reviewer almost nothing. A useful statement pins down dates, frequency, duration, and concrete examples of activities you can’t do or can only do with difficulty.
Describe Functional Limits in Concrete Terms
VA disability ratings are based on how much a condition reduces your ability to function in daily life and employment.2eCFR. 38 CFR 4.10 – Functional Impairment Write to that standard. For a knee injury, explain that you can walk about two blocks before the pain stops you, that you can’t kneel or squat, and that stairs need a handrail. For a mental health condition, describe how it affects your sleep, concentration, relationships, or ability to hold a job.
The regulation notes that someone may be “too disabled to engage in employment although he or she is up and about and fairly comfortable at home or upon limited activity.”2eCFR. 38 CFR 4.10 – Functional Impairment If your condition looks manageable during a short medical appointment but falls apart over a full workday, this is where you explain the gap.
Document Flare-Ups
Flare-ups are hard for medical exams to catch because they often aren’t happening during your appointment. Include how often flare-ups occur, how long each episode lasts, what triggers them, and what you cannot do during one. If a flare-up means you miss work, cancel plans, or spend hours lying down, say so. Mention any medications or devices you use during episodes, such as a brace, heating pad, cane, or specific prescription. Keeping a simple log of dates and symptoms before you write makes this section easier and more credible.
Connect the Condition to Service
For an initial claim, the VA needs a link between your current disability and something that happened in service. Identify the in-service event, injury, or exposure as specifically as you can — unit, location, approximate date, what happened. Then describe when symptoms first appeared and how they have progressed. A chronological account helps the Rating Veterans Service Representative follow the timeline from service to the present.
Section III: Signature and Date
Field 9 is your signature and Field 10 is the date you signed. That signature carries real legal weight. The form warns: “The law provides severe penalties which include fine or imprisonment, or both, for the willful submission of any statement or evidence of a material fact, knowing it to be false.”3Department of Veterans Affairs. VA Form 21-4138, Statement in Support of Claim Under federal law, unsworn written declarations to government agencies carry the same weight as sworn statements when signed under penalty of perjury.4Office of the Law Revision Counsel. 28 U.S. Code 1746 – Unsworn Declarations Under Penalty of Perjury Everything in Section II needs to be true and accurate to the best of your knowledge.
If you submit through VA.gov, your typed name works as a valid electronic signature.
How to Submit the Completed Form
You have three ways to get the form to the VA.
Online Through VA.gov
If your claim is already in the system, upload the completed PDF using the claim status tool on VA.gov. For other documents, the VA directs you to the QuickSubmit tool through AccessVA.5Veterans Affairs. Upload Evidence to Support Your Disability Claim Online submission gives you the fastest confirmation of receipt.
By Mail
Mail the completed form to:
Department of Veterans Affairs
Claims Intake Center
PO Box 4444
Janesville, WI 53547-44446Veterans Affairs. How to File a VA Disability Claim
Use certified mail with a return receipt. The VA generally uses the date it receives evidence as the starting point for processing, so proof of the delivery date can matter.
In Person
Hand-deliver the form to your local VA Regional Office. Ask staff to date-stamp your copy as proof of when you turned it in.
Watch the Timing
You can keep uploading supporting documents for up to one year from the date the VA receives your claim. But if you don’t provide any evidence or respond to VA requests within 30 days, the VA may decide your claim early based on what it already has.5Veterans Affairs. Upload Evidence to Support Your Disability Claim Getting your statement in promptly avoids an unfavorable early decision.
How the VA Weighs Your Statement
Once received, the form is scanned into your electronic claims folder. A Rating Veterans Service Representative reviews your lay evidence alongside your medical records, service records, and any other documentation in the file, using the rating schedule in 38 CFR Part 4.7eCFR. 38 CFR Part 4 – Schedule for Rating Disabilities
Lay evidence is evaluated on competency and credibility. Competency asks whether you’re in a position to observe and describe what you’re claiming, and you’re always competent to describe your own pain, symptoms, and limitations. Credibility is about whether the reviewer finds your account believable and consistent with the rest of the evidence.1eCFR. 38 CFR 3.159 – Department of Veterans Affairs Assistance in Developing Claims A statement that lines up with your treatment records and service history carries more weight than one that contradicts them.
Under 38 U.S.C. 5107(b), when the positive and negative evidence on any issue is roughly equal, the VA must resolve the tie in your favor.8Office of the Law Revision Counsel. 38 USC 5107 – Claimant Responsibility; Benefit of the Doubt A credible lay statement can be the piece of evidence that tips that balance, especially in claims where medical records are thin.
