Disowning Family Members

^^^^^^^^This, my sister did not speak to my father for 30 years, and he never knew his grandchildren, but when he died, she wasted no time looking for her share of his estate. Granted, he was an abusive alcoholic and we all had a strained relationship with him, but at least my one brother and I made an effort. The other 2 only cared about the money. My asshole brother has also been extremely disrespectful to my wife, which she does not deserve, and I will NOT tolerate.
The only way that you can keep her from getting a dime would be if everything was put pod and tod to you and your brother. I can understand why you feel like you do and I don't blame you
