I know when my wife's uncle died, he had 3 children from 3 separate marriages. his current wife (along with their daughter) got to stay in the house for however long she wanted, only had to give up half if she sold. she did eventually sale, but one of his sons refused to sign off because he hated her and refused to even talk to her. I never asked what happened to that portion of the money. not sure if it's sitting in limbo the last few years or if she got it because he refused to accept it. now, it wasn't a ton of money, the profit from the house was probably under 100k.
