My mother passed away about 8 years ago. I am the son of her first marriage. Subsequently she had three other children from her second marriage.

All four of us are alive. There is property and other assets that were left when my mother and her husbancd passed away. My sister advised me that I was not included in my mother's will but that my mother specifically instructed her to take care of me upon her death. My question is: Do I have any rights to my mother's share of her estate even though I was not included in her will. At least my sister and one of the brothers do want me to participate in my mother's share of the estate.
