I moved to my mother's town in 1998 to help her and my father. I continued to help her checking on her every day until her death this year. In 2005 she changed her life insurance policy beneficiary from all 4 children to myself. My brother is the executor of the will mom wrote in the late 1980's. He claims I must split the life insurance check with the other children equally because the will states all assets and personal items to be divided equally. He is threatening me with hiring a lawyer to get the money.
