Yes, a family member was cut out of their parents will, because he stood up to them, we did too, but it doesn’t matter now because the family member died last year and the ‘inheritance’ is going to be used for Nursing Home fees.
But DH goes to see his mother out of duty, not affection and always said that he would split his share with his DB, as I said it is a moot point now.
Not all sons and daughter who dislike their parents refuse to see them, sometimes they just see them less frequently, but once the trust and love is gone it’s gone, you can only take so much.
