Did you receive a Board's decision that you disagree with?
yes I want to appeal
Okay, you can appeal to the U.S. Court of Appeals for Veterans Claims. You can hire an attorney to represent you, or you can represent yourself.
Do I appeal it all or do I have to state what parts I want to appeal?
You can include all or just some of the issues VA has decided . You will need to list the issue you disagree with and the VA decision date for each
I believe I missed the deadline in submitting my appeal due to VA's mistake. What evidence do I need to back up my claim?
To prove a CUE error, you must show the correct facts and be able to prove that the VA incorrectly applied the law at that time.
Can the VA help me to gather all the right evidence?
Yes, they are required to help you if you need it on your claim.
Do they have to help with me a supplemental claim too?
