I still need to find out about legacy claim or appeal. I see what you mean. What do I do in order to obtain a statement of the case?
You must file a Notice of Disagreement VA Form 21-0958 within 1 year of the date on your decision.
Thanks, I'll do that. What does "duty to assist" entail, by the way?
VA's Duty to Assist requires VA to assist you in getting evidence, such as medical records, that is needed to support your case. VA's Duty to Assist applies during your initial claim and if you file a Supplemental Claim.
