VCAA and Development Letters — What VA Must Tell You and How to Respond

When VA receives your claim, the law requires it to tell you what evidence the claim needs and who is going to get it. That letter is often called a VCAA letter or a duty-to-notify letter (VA.gov calls it "section 5103 notice"), and later requests for records or statements are often called development letters. This guide covers what the notice must say, when none is owed, the other notices VA must send during and after a claim, and how to answer a letter.

The rules below come from 38 U.S.C. 5103, 5103A and 5104 (U.S. Code, 2024 edition, on govinfo) and 38 CFR 3.103, 3.109 and 3.159 as published on eCFR (current through October 26, 2026), and from VA's "evidence needed" page on VA.gov, all read on October 28, 2026.

Where the duty comes from

Section 5103 of title 38 was added in 2000 by Pub. L. 106-475, the Veterans Claims Assistance Act of 2000 (VCAA). Section 5103 is the duty to notify. Section 5103A is a separate duty, the duty to assist. VA's regulation for both is 38 CFR 3.159.

What the notice must say (38 CFR 3.159(b)(1))

When VA receives a complete or substantially complete initial or supplemental claim, it will notify you of:

- any information and medical or lay evidence that is necessary to substantiate the claim - which of that information and evidence, if any, you are to provide - which of it, if any, VA will attempt to get on your behalf

Section 5103(a)(1) says VA provides the notice to you and your representative, if any, "by the most effective means available, including electronic communication or notification in writing." Section 3.159(f) adds your fiduciary, if you have one.

The notice also starts two clocks. Information and evidence you are told to provide must be provided within one year of the date of the notice, and if you have not responded within 30 days, VA may decide the claim on what is in the file. Time limits for submitting evidence explains how the two work together.

What the notice looks like in practice

VA.gov says it is required by law to tell you what evidence you need to provide, and that its evidence page is a summary of those requirements, called "section 5103 notice"; the official requirements are in VA Form 21-526EZ. For an original claim tied to active-duty service, VA.gov lists evidence that you have a current physical or mental disability, that an event, injury or disease happened during your service, and that there is a link between the two. It lists different evidence for increased, secondary and supplemental claims.

So a notice tells you what VA still needs, and that is where to put your effort. If the missing piece is the link to service, a medical opinion addressing that link is the kind of evidence that speaks to it; see nexus letters.

When no notice is owed

Section 3.159(b)(3) says no 5103 notice is owed:

- for a supplemental claim received within one year of the date VA issued notice of a prior decision - for a request for higher-level review - for a Notice of Disagreement to the Board - when, as a matter of law, the benefit claimed cannot be established

The statute adds that no notice is required where VA can award the maximum benefit based on the evidence of record (5103(b)(5)), and that a new notice is not required for a claim filed while an earlier one is pending if the earlier notice already covers it and was sent within one year (5103(b)(4)).

Other notices VA must send

The decision notice must identify the issues decided, summarize the evidence considered and the laws and regulations that apply, list any favorable findings, identify for a denial the elements that were not met, identify where applicable the criteria for service connection or the next higher level of compensation, explain how to get the evidence used, and summarize your review options (3.103(f)(1)–(8); 38 U.S.C. 5104(b)). How to read a VA decision walks through a decision letter, and rating reductions and your protections covers proposed reductions.

How to answer a development letter

- **Find the specific request.** Each item names something VA is missing. Answer every item, not just the first. - **Give records VA can find.** For each provider, 3.159(c) asks you to identify who holds the records, the approximate dates, and the condition treated. Use full names and addresses on VA Forms 21-4142 and 21-4142a; vague entries can slow the request. - **Say so if you can't get something.** Tell VA in writing what you could not get and why, and offer what else you have. Because VA's notice about records it couldn't get says you are ultimately responsible for the evidence, sending records yourself is often the most direct route. - **Make statements specific.** A personal or buddy statement is most useful when it is concrete and in order: what happened in service, when symptoms started, how they have changed, and how they affect work and daily life. - **Watch the dates.** VA may decide after 30 days without a response, and the one-year period runs from the date of the notice. If you need more time, ask before the deadline; 38 CFR 3.109(b) lets VA extend time limits for good cause shown. - **Keep proof.** Keep copies and confirmations of everything you upload or mail. - **Involve your representative.** VA sends these notices to your representative too (3.159(f)), and a VSO or other accredited representative can help you answer them.

If VA skipped a notice it owed

If you think VA did not send a notice it owed you, or left out what the claim needed, you can raise that in a decision review. The duty to assist guide covers how higher-level reviewers and the Board handle errors in VA's development of a claim.

Frequently Asked Questions

What is a VCAA letter?

It is the notice VA sends under 38 U.S.C. 5103 and 38 CFR 3.159(b)(1) after it receives a complete or substantially complete initial or supplemental claim. It tells you what information and evidence the claim needs, which part you are to provide, and which part VA will try to get for you.

How long do I have to respond?

Information and evidence VA tells you to provide must be provided within one year of the date of the notice. If you have not responded within 30 days, VA may decide the claim on the evidence in the file. If it does and you send the requested evidence within the year, 3.159(b)(1) says VA must readjudicate, and 3.159(b)(4) says evidence sent after a decision goes in through a review option such as a supplemental claim.

Does VA send a 5103 notice for a supplemental claim?

Not if VA receives it within one year of the date VA issued notice of the prior decision. Section 3.159(b)(3) says no notice is owed then, or for a higher-level review request or a Notice of Disagreement to the Board.

What must my decision letter include?

Under 38 CFR 3.103(f): the issues decided, a summary of the evidence considered, a summary of the applicable laws and regulations, any favorable findings, for a denial the elements not met, where applicable the criteria for service connection or the next higher level, how to get the evidence used, and a summary of your review options.

What if VA says it could not get my records?

Section 3.159(e) says the notice must identify the records, explain what VA did to get them, describe what VA will do next, including deciding on the evidence of record unless you send them, and tell you that you are ultimately responsible for providing the evidence. If you can get the records yourself, send them.
