My grandpa died and my gram is his life insurance beneficiary. She is on Medicare and they pay for her nursing home living (she has dementia). They currently take all of her SS etc except $50 a month. Can her POA (my sister) deposit the life insurance check into an account on Gram's behalf? All other bills are paid and Gram is not on the account so it won't impact Medicare eligibility. The money will be used to purchase a headstone as well as Gram's future funeral expenses.
