My sister-in-law passed away 3 years ago. My brother is dying from leukemia. He is getting very weak, but was able to tell us what he wants done with things after he passes. Problem is, he has no will and he never changed his wife from beng his beneficary. He has my mother and 4 living siblings, a step son and granddaughter by his step son. Can you tell me what steps we need to take after he passes and what will happen to his money and estate? Thank You.
