Effective Date Disputes

How effective dates are assigned

Effective dates are governed primarily by 38 CFR § 3.400. The general rule is straightforward: the effective date is the later of (1) the date entitlement arose, or (2) the date the VA received the claim. There are important exceptions that often allow for earlier dates and significant back pay.

Common ways to get an earlier effective date

• Claim filed within one year of separation — effective date is the day after separation from service.
• Intent to file (VA Form 21-0966) — preserves the effective date for up to one year while you gather evidence.
• Look-back rule for increases — up to one year prior to filing if medical evidence shows the worsening occurred earlier.
• Liberalizing law or regulation — when a new law (like the PACT Act) creates entitlement, the effective date can be tied to the law's effective date.
• Continuous appeals — keeping the original claim alive through HLR, Supplemental Claim, or Board appeal preserves the original effective date.
• Clear and Unmistakable Error (CUE) — a successful CUE motion can set the effective date to the date of the original (erroneous) decision.

Clear and Unmistakable Error (CUE)

CUE is a high-bar legal challenge to a final VA decision. It requires showing that the correct facts, as they were known at the time, were not before the adjudicator, OR that the law in effect at that time was incorrectly applied — and that the error was outcome-determinative.

CUE is not a second chance to re-argue the evidence. Disagreement with how evidence was weighed is not CUE. CUE motions can be filed at any time, even decades after the original decision, and a successful CUE motion typically results in a substantial retroactive award.

How effective dates are disputed

1. Identify the decision that assigned the effective date you believe is wrong.
2. Determine your theory — earlier informal claim, intent to file, look-back rule, CUE, or continuity of appeals.
3. If within one year of the decision, file an HLR or Supplemental Claim challenging the effective date.
4. If the decision is final and outside the one-year window, consider a CUE motion.
5. Gather documentary proof of earlier filing dates, prior correspondence, or the regulation/law in effect at the relevant time.

Where these claims break down

• ×Assuming the assigned effective date is correct without checking for earlier informal claims in the C-file.
• ×Confusing CUE with general disagreement — CUE has a strict legal standard.
• ×Letting decisions become final without preserving the effective date through timely appeals.
• ×Forgetting to claim back pay tied to a liberalizing law (PACT Act, Nehmer cases for Agent Orange).
• ×Not requesting a copy of the C-file before arguing about earlier filings.
