Getting a denial from the Board of Veterans’ Appeals can feel like the end of the road. In many cases, it is not. A Board decision is often the point where a veterans benefits case moves from the VA system into a separate federal court process. That transition can feel technical, fast-moving, and easy to misunderstand, especially when the clock starts running immediately.
In general terms, one of the most important deadlines in veterans law is the 120-day period to appeal a final Board decision to the U.S. Court of Appeals for Veterans Claims, often called the CAVC. Congress set that deadline in 38 U.S.C. § 7266, which states that a person adversely affected by a final Board decision files a notice of appeal with the Court within 120 days after the date notice of the decision is issued.
In this post you’ll learn how the 120-day appeal window works, what gets filed first, where the appeal goes, what the Court actually reviews, and where veterans often lose time without realizing it. If you want a broader overview before diving into the deadline itself, it may help to start with this more general explanation of what the CAVC appeal process looks like from the Board forward.

The CAVC reviews final decisions of the Board of Veterans’ Appeals, not ordinary VA regional office decisions. The Board is the part of VA that issues the final agency decision on an appeal, and the Court is not part of VA. The Court’s own guidance for unrepresented appellants explains that it reviews what the Board did in the case and does not take new evidence or hold trials, which is a very different role from VA adjudication at earlier stages of a claim. See the Court’s instructions for unrepresented appellants and its Rules of Practice and Procedure.
That distinction matters because many veterans receive multiple VA letters over time. Some are development letters. Some are rating decisions. Some are remands. Some are Board decisions that grant part of a claim and deny part of it. The right to appeal to the CAVC generally attaches to the final Board decision, or the denied part of that decision.
A few practical questions often help here:
If the paperwork is confusing, that is often the point where attorney review becomes especially valuable. A CAVC appeal is heavily deadline-driven, and a lawyer with documented experience in veterans appeals may be able to identify whether the Court has jurisdiction and which issues are actually preserved.
The basic rule sounds simple: 120 days from the date notice of the Board decision is issued. That language comes directly from 38 U.S.C. § 7266.
In plain terms, many veterans calculate from the day they opened the envelope. That is often not how the statute is written. The safer starting point is usually the date shown on the Board decision itself, because the statute measures from when notice of the decision is issued, not from when it is actually read. The Court’s forms and filing instructions are built around that timing framework as well. See the Court’s forms and fees page.
For example, if a Board decision is dated April 15, 2026, the 120-day count typically runs from that date, not from the day the letter arrives in the mailbox. That can make a real difference when a veteran receives the decision several days later.
This is also where delay becomes risky. A veteran may spend weeks deciding whether to file a supplemental claim, seek reconsideration at the Board, or appeal to the Court. Those choices can interact in complicated ways depending on the procedural posture. An attorney may help sort out which path preserves the broadest range of options without accidentally consuming the Court deadline.
