Father (79) step mom (80) disagree about estate planning. He wanted 1/4 to go to each child. Step mother has a son, my father had three kids (one died) so two are left. I plan to help my Dad find an attorney and gather his information, but I am concerned that we will find my step mom unwilling to sign even if we abide by the law (50/50) split of assets.
What can be done if she refuses to sign? Even if it's fair? Thank you
