Disowning Family Members

It's not about hatred. It's about respecting the wishes of others.
That's why you make out a will and spell out how things are distributed.
I always say those that love you will accept what you left them. they may not understand why you did it the way you did, and left someone more then you, butthey will still love you. If you left someone who only cared about how much they could get. Never cared about you and never will.
An irrevocably trust is a good way to go.
^^^^^^^^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.
