Errors in the "buddy letter"

Question:

Greetings, Quick question, are you able to edit/revise/ write a supplemental buddy letter, once it has been submitted for appeal? The letter that was submitted, while nearly everything was right, had the dates written in the incorrect place. Are we able to change that or notify the VA? Or does it not really matter?

Jim's Reply:

Does it matter that dates are wrong in evidence you've submitted? Of course it matters. You're supposed to submit factual data, not near guesses. Yes, I'd say you should write a letter to file stating exactly what the problem is and then submit that and hope someone pays attention.
