My father has been legally separated from my mother for about 15 years. She receives a portion of his USAF retirement and SS checks every month per court order. Dad also receives a monthly VA disability check.
Our first attempt at doing the A&A application resulted in a denial.

The forms didn't provide any space for handling this type of situation. My mother also receives her own small SS and has an IRA. No other assets for either.
Is A&A even possible in this situation?
