If a VA decision became final years ago, but something about it still feels plainly wrong, you may have heard about a CUE motion and wondered whether it could reopen the issue. That reaction is common. Clear and unmistakable error — usually shortened to CUE — is one of the most misunderstood concepts in veterans law.
It can be powerful, but it is also narrow. A successful CUE claim can lead to revision of an old final decision as if VA had gotten it right the first time, which is why veterans and surviving family members often look at CUE when retroactive benefits may be significant. Under 38 C.F.R. § 3.105 and 38 U.S.C. § 7111, VA and the Board of Veterans’ Appeals both have mechanisms for revising certain final decisions based on clear and unmistakable error.
In this post you’ll learn what a CUE motion is, how it differs from a normal appeal, what kinds of mistakes may qualify, what usually does not qualify, and why many veterans find it helpful to have a lawyer evaluate the record before filing. If you want a broader overview of how old VA rulings can sometimes be revised, this guide on fixing an old VA decision based on an obvious legal error gives useful background.

A CUE motion is a request to revise a final VA decision because the decision contained an error of fact or law that was not debatable and that would have changed the outcome. The governing regulation for many agency decisions says prior final decisions are accepted as correct unless the evidence establishes clear and unmistakable error, and if CUE is found, the decision is reversed or amended under 38 C.F.R. § 3.105(a). For Board decisions, Congress created a separate process in 38 U.S.C. § 7111, with implementing rules in 38 C.F.R. §§ 20.1400–20.1411.
In simple terms, CUE is not about whether VA could have decided differently. It is about whether the earlier decision was undebatably wrong based on the record and the law that existed at the time. The Board’s CUE regulation says clear and unmistakable error is “a very specific and rare kind of error,” and that the result must have been “manifestly different” but for the error under 38 C.F.R. § 20.1403.
That is why people often describe CUE as an exception to finality. Once a decision becomes final, ordinary disagreement usually is not enough. CUE is one of the limited ways final decisions can still be revised.
The biggest reason is often retroactive benefits. If a final decision is revised for CUE, the corrected decision generally has the same effect as if it had been made on the date of the original decision. That principle appears in both the Board statute, 38 U.S.C. § 7111(b), and the Board regulation, 38 C.F.R. § 20.1406.
That can matter when the disputed issue goes back many years. For example, some CUE allegations involve:
A veteran may also look at CUE when the usual review lanes are no longer available because the decision became final long ago. VA’s current decision review system includes options like Higher-Level Review and Board Appeal for newer decisions, but those are different from a CUE theory aimed at an older final ruling, as VA explains in its decision review FAQs and Higher-Level Review page.
This is where many people get tripped up.
