Disowning Family Members

I don't think that hatred can be justified, even as bad as my first wife did me I don't hate her, I guess I just don't believe in hate
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.
