This is very interesting to me! I have been collecting information and helping my mother, and it now sounds like she may want to submit 21-534EZ.
She already receives a Navy Pension (which I believe is the "SBP annuity" - it's based on my father's navy service in WWII, she continues to get a smaller portion of his benefit after he died in 2005) in addition to SS pension. This is her only income; she has less than 80K in assets, and she has "permanent need to regular aid and attendance" (we have form 21-2680 completed/signed by her physician).
She has already submitted (just a few weeks ago) form 21-4138 statement in support of claim, as an "informal claim" (citing 38 CR 3.155 Informal claims as recommended elsewhere on this site) to get the ball rolling.
Is collective wisdom here that we should now submit 21-534EZ? Or is it too late for that, now that she already submitted the informal claim? She has received the return receipt from mailing that form, but not yet a formal letter acknowledging receipt.
The 21-534EZ instructions say that you may file an informal claim to get started, but it should say
"I intend to apply for compensation/pension benefits under the FDC Program.... etc".
The informal claim we submitted for her didn't use this wording.
Thanks so much for all of your help!!
