My dad is a korean war veteran, and has past away over 20 years ago. My mom had since remarried and divorced years later. Is my mom entitled?

to VA benefits under my father for housing. She is currently living with my niece and pays 1100 rent, and collects SS$1450, and dips into her meager savings of $20K every money. to pay bills, insurance, car payment. The rate she is going she will be out of money by next year.
