My Mom lives with my sister a mental case worker and she receives 2000 a mo. but does not cook feeds my mother fast food and wastes money. No cooking is involved,enless my mother does it. my mother pays for all expenses, and their is very little food in the house, my mother is 91 and cannot look after herself and does not want to go to a nursing home. she gets around well. her memory is excellent. and my mother stated today when I went to take her to the doctor for bronchitis that my sister was cutting back on food because she wants to go see her son and grandkids in Utah. between their two incomes it come to 5200 a month. is that income from my mother to my sister taxable? im at a loss for a lack of personal care that my sister gives my mother. ive brought this up but she now refuses to let me see my mother, or check on her well being.
