VA clear and unmistakable error: what CUE is and how to file
A CUE request reaches back into a decision that became final years or decades ago and, if it succeeds, pays from the date the original decision should have used. The standard is very high, and the regulations close off several common lines of argument.
Clear and unmistakable error, or CUE, is an error of fact or law in a final VA decision that leaves no room for reasonable disagreement that the outcome would have been manifestly different without it. It is judged on the record and the law as they stood when the decision was made, and it can be raised at any time. How you raise it depends on who made the decision: a request about a regional office decision goes to VA, and a motion about a Board decision goes to the Board (38 CFR § 3.105(a); § 20.1403; § 20.1404).
A regional office decision becomes final once the time to ask for a review or appeal it to the Board runs out, generally one year from the decision notice. A Board decision is final on the date stamped on it. After that, a new or supplemental claim usually pays only from when it is filed.
Clear and unmistakable error is one exception. Under 38 CFR § 3.105(a), final decisions are accepted as correct with respect to the evidentiary record and the law that existed at the time, in the absence of clear and unmistakable error. Where such error is shown, the prior decision is reversed or amended, and it is treated as though the correct decision had been made at the time. Under § 3.400(k), the effective date becomes the date benefits would have been payable had the corrected decision been made back then. Another exception: if VA later receives relevant official service records that existed but were not in the file when it first decided the claim, it reconsiders the claim, and an award based on them can reach back to the original claim date or the date entitlement arose, whichever is later (§ 3.156(c)).
There is no time limit on raising CUE. A decision from 1974 can be challenged today.
The standard, and why it is so hard
CUE is not "the VA got it wrong." It is closer to "no reasonable adjudicator applying the law to that record could have reached that conclusion." Three things must all be true:
- Either the correct facts as they were known were not before the adjudicator, or the law in force at the time was incorrectly applied.
- The error is undebatable. Not merely arguable, not a matter on which reasonable people could differ. If two adjudicators could legitimately have reached different conclusions, it is not CUE.
- The error manifestly changed the outcome. A mistake that would not have altered the result, even if plainly a mistake, does not qualify.
The review is confined to the record and the law as they existed at the time of that decision. You cannot use evidence that did not exist then, and you cannot use a later change in the law or a later court interpretation.
Disagreement with how evidence was weighed. Arguing the rater should have believed your doctor over the examiner is a weighing disagreement, and weighing disagreements can never be CUE, by definition. New evidence. Anything that was not in the record at the time is outside the scope, with narrow exceptions that differ by decision-maker. For regional office decisions made on or after July 21, 1992, VA's General Counsel has held that failing to consider records already in VA's possession can be CUE if it affected the outcome; for older regional office decisions, it cannot. For Board decisions on legacy appeals issued on or after that date, the record includes relevant documents VA held up to 90 days before the file went to the Board, if they could reasonably be expected to be part of it. Failure to assist. A breach of the duty to assist is not CUE, because the argument is that the record should have been better, not that the decision was wrong on the record that existed.
Errors that may qualify
Errors that are mechanical, legal, and provable from the face of the file. Each one still has to have manifestly changed the outcome:
- A regulation applied incorrectly. The rating criteria in force at the time plainly required 30% on the findings recorded, and 10% was assigned.
- A regulation ignored altogether. The bilateral factor was never applied where two paired limbs were rated.
- Arithmetic. Combined rating tables misapplied, producing a total the table does not support.
- An effective date contrary to the regulation. A claim filed within a year of separation, with the date set at the filing date instead of the day after separation.
- Evidence in the record that was overlooked. Not evidence that was weighed and rejected, which is a weighing question, but evidence that plainly was never considered at all.
- A statutory entitlement never adjudicated. SMC-K entitlement obvious on the recorded findings and never addressed. See Special Monthly Compensation.
The pattern is that a successful CUE points at something on the page and says: this rule existed, these facts were recorded, and the two do not match. It does not say: I should have won.
A rating decision dated October 14, 2003 rated a veteran's ankles at 20% each and hypertension at 10%, and combined them to 40%. It was never appealed and became final.
A 2026 CUE request would test it on its own record:
- The law then. 38 CFR § 4.26, in its July 1, 2003 edition, required that when a partial disability results from disease or injury of both legs, the two ratings are combined, 10% of that value is added (not combined), and the result is treated as one disability before anything else is combined. § 4.25 then rounded the final value to the nearest 10, with 5 rounding up.
- The facts then. The code sheet itself lists both ankle ratings. The two 20s combine to 36, and 10% of 36 is 3.6, giving 39.6, carried as 40. The 40 and the 10 combine to 46, which converts to 50%. Without the bilateral factor, 20, 20 and 10 combine to 42, which converts to the 40% assigned. Nothing has to be weighed.
- The outcome. 50% instead of 40%, a manifestly different result shown on the face of the decision. Had the left ankle been rated 10%, the omission would not qualify: 20, 10 and 10 reach 40% with or without the factor.
If the error is found, § 3.400(k) pays from the date benefits would have been payable had the corrected decision been made in October 2003. Arguing that a private doctor deserved more weight would be a weighing disagreement, not CUE (§ 20.1403(d)(3), which § 3.105(a)(1)(vi) applies to regional office decisions).
Use the ordinary lanes if you still can
If the decision is less than one year old, do not file CUE. It is not even available yet: § 3.105(a)(1) reaches only final decisions, and a regional office decision is not final while its one-year review window is open. You have far better options, all of which use a lower standard:
| Situation | Use |
|---|---|
| Decision under a year old, the rules were misapplied to the existing record | Higher-Level Review (VA Form 20-0996) |
| Decision under a year old, you have new evidence | Supplemental Claim (VA Form 20-0995) |
| Any age, you have new and relevant evidence | Supplemental Claim |
| Final decision, no new evidence, an undebatable legal error on the old record | CUE |
A Supplemental Claim can be filed at any time, not just within a year, so a final decision is not a dead end even without CUE. The difference is the effective date: a Supplemental Claim generally pays from the date you file it, while a successful CUE reaches back to the date the original decision should have used. That gap is the entire reason to attempt CUE.
How to raise it
There is no dedicated CUE form for a regional office decision: VA's procedures manual says no specific claim form is required, as long as the request is in writing and signed by the claimant or a representative. A signed letter meets that, and so does a general statement form such as VA Form 21-4138, Statement in Support of Claim. A CUE challenge to a Board decision is different and goes to the Board itself as a motion, filed at Board of Veterans' Appeals, P.O. Box 27063, Washington, DC 20038 (38 CFR § 20.1404(c)). So does a regional office decision that the Board later decided on appeal on the same issue: § 3.105(a)(1)(v) takes it out of the regional office's reach, and the challenge has to be aimed at the Board decision. The same rule stops the regional office from revising an issue that a court decided on appeal.
Whatever the route, the request must be in writing, signed by the claimant or a representative, carry the claimant's name and VA file number, and be specific. A general assertion that a past decision was wrong is not a valid CUE request: VA takes no action on it until the specific error is identified, and a vague motion to the Board is dismissed without prejudice to refiling. The lasting damage comes from a denial on the merits. Once VA finally denies CUE on a given basis, that basis cannot be raised again, and once a Board ruling on a CUE motion becomes final, that Board decision on that issue is closed to CUE for good. State:
- The exact decision, by date, and the specific issue if it decided more than one.
- The exact error, identified precisely.
- The law or regulation as it read at that time, cited.
- The evidence that was in the file then, cited to the record.
- Why the outcome would manifestly have been different.
The C-file holds the rating worksheet, the examiner's report, and the prior decision, which is the record the review is confined to. It is not a filing requirement, but citing that record is hard without it.
A realistic expectation
The regulation itself (§ 3.105(a)(1)(i)) calls CUE "a very specific and rare kind of error," and that is by design rather than by accident: the standard exists to protect the finality of decisions, not to provide a second appeal. Filing one on a weighing disagreement cannot succeed, because the regulations exclude weighing disagreements from CUE (§ 20.1403(d)(3), which § 3.105(a)(1)(vi) applies to regional office decisions).
But where a genuine mechanical error sits in an old decision, and particularly where an effective date is provably contrary to the regulation, CUE is one of the few routes back to the earlier date. Read the decision, read the regulation as it stood, and see whether the two actually match. If they plainly do not, it may be worth pursuing, ideally with an accredited representative.
CUE questions
What is clear and unmistakable error in a VA decision?
Clear and unmistakable error, or CUE, is a very specific and rare kind of error of fact or law in a final VA decision. Either the correct facts as they were known at the time were not before VA, or the law in force at the time was applied incorrectly, and the error has to compel the conclusion, one reasonable minds could not differ on, that the result would have been manifestly different without it. Review uses the record and the law that existed when the decision was made. A decision revised for CUE takes effect as if the corrected decision had been made on the original date (38 CFR § 3.105(a); § 20.1403).
What errors may qualify as CUE?
Errors that can be shown from the old record and the law at the time may qualify, but only if they manifestly changed the outcome: a rating rule in force at the time applied incorrectly to the recorded findings, a required rule such as the bilateral factor left out, combined-rating arithmetic done wrong, or an effective date set contrary to the regulation. Some arguments never qualify: a disagreement about how the evidence was weighed, VA's failure to fulfill its duty to assist, a new diagnosis that corrects an earlier one, and a later change in how a law or regulation is interpreted (38 CFR § 20.1403(d) and (e); § 3.105(a)(1)(iv)).
How do I file a CUE request about a regional office decision?
Send VA a written request signed by you or your authorized representative. No specific form is required. It must include the claimant's name, the VA file number, and the date of the decision, and name the specific issue if the decision covered more than one. It must state clearly and specifically the error of fact or law, the legal or factual basis for it, and why the result would have been manifestly different without it; a general claim that VA failed to follow the rules is not enough. A regional office cannot revise an issue that the Board or a court has since decided on appeal. If the Board decided it, the CUE challenge goes against the Board decision instead. If a court decided it, CUE is not available against either decision on that issue (38 CFR § 3.105(a)(1)(v) and (vii); 38 CFR § 20.1400(b); M21-1 X.ii.5.A.2.a).
How do I file a CUE motion about a Board decision?
File a written motion, signed by you or your representative, with the Board of Veterans' Appeals, P.O. Box 27063, Washington, DC 20038. It must include the veteran's name, the VA file number, and the date of the Board decision, name the specific issue if the decision covered more than one, and set out the specific error, its legal or factual basis, and why the result would have been manifestly different. A motion that does not meet these requirements is dismissed without prejudice to refiling. Issues a court has decided are not open to a Board CUE motion, and once the Board finally decides a CUE motion on an issue, that issue in that Board decision cannot be challenged for CUE again (38 CFR §§ 20.1400, 20.1404, 20.1409(c)).
Is there a deadline to raise CUE?
No. A request about a regional office decision can be made at any time after the decision is final, and a motion about a Board decision may be filed at any time. The deadlines that matter are the ordinary review deadlines. A regional office decision becomes final only once the time for a review option or a Board appeal has run out, generally one year from the decision notice, and CUE is not available before then. A Board decision is final on the date stamped on it unless reconsideration is ordered (38 CFR §§ 3.105(a)(1), 3.160(d), 3.2500(a), 20.1100, 20.1404(c)).

A CUE claim turns on the regulation text as it read when the old decision was made, and a badly framed attempt, once finally denied, can close off a good argument permanently.
