My grandfathers will(2006)(he is still alive) gave my sister and I equal share. She moved to Fl to be near him and since then the will has changed to she gets 1.8M and I get 400,000 as she convinced him I need nothing and she is destitute with a child and has a worthless husband. Not true of course. Since she has lived there for the past 1 1/2 years I can hardly get him to talk to me. He showed me paperwork where she had written down everything she wanted on the will. I ask him if he thought that was fair and he said he would put me on a 500,000cd, which he did as I went to the bank with him but as soon as I left he took me back off. I don't understand as he invites me down to visit and offers to pay my way. I have never done anything to him or her. Do I have a right to contest.
