In form 21-527EZ Section II question #16A asks "Did you receive any type of separation/severance retired pay?" I am doing this form for my grandfather, a WWII Veteran, who was in the Navy until September of 1960. He receives monthly retirement pay from Defense Department. Is that what they are referring to in this question? In Section I, question #5 asks, "Have you ever filed a claim with VA?" He tried to get an eye procedure paid for many years ago, but is that they type of thing they are asking about here, or are they just referring to an application for ongoing aid like this A&A? Section IX asks for "Other Income Expected". Is their social security income supposed to go there, and, if so, is it net or gross? What is the Fully Developed Claim Certificate and do where do I find the claim number that they are asking for? On form 21-0845 question 3 asks for "Address of Beneficiary/Claimant". Whose address should that be? My Grandpa or me? (He is going to foster care so I will be getting his mail, but he will live somewhere else). Question #4 asks for a VA File Number; where do I get that? And,finally, does the DD214 need to be certified by a notary? Thank you for your help.
