how long do i have to file a notice of disagreement?
After your veteransâ disability claim has been denied by your regional VA office, you may: 1  File a Notice of Disagreement within one year of the date of the letter notifying you of the decision on your initial claim. This appeal goes to your regional office and asks that office to reconsider your claim. Once you file the Notice of Disagreement, the VA will reply with a Statement of the Case.
