<prompt> Human: So here is the situation. My father has set aside money for me to inherit when he passes. From what he has told me, he has worked with his lawyer to guarantee that i would inherit and choose what happens to it from there. Here is the rub:He is married to a woman that he has been separated with for over 10 years. They still vacation together and have a loose affiliation even outside of that with family members and what not. They still maintain their marriage and do some tax type items together etc.The concern i have is even though he has designated it to come to me, and even though she swears that she would never challenge my claim, i am worried that when the time comes she may change her tune. He is in poor health lifetime smoker and drinker, etc. I dont think we are anywhere close to the day, but it makes for really awkward talks. He maintains she couldnt touch it even if she wanted to. I have read in multiple places that regardless of who he designates she can still make a play for it. What do i need to do to make sure i am protected in this scenario. I know that once he is gone she will change her tune and do everything in her power to try and obtain this money. Honestly i have no problem seeing she gets a share, but i feel like due to my fathers wishes that should be up to me to decide and not the court.Thanks in advance. Edit: Just to be clear, i am not concerned with him changing his mind at all. It is purely up to him, however my concern is that from what i have been told his wishes have no bearing. He can leave everything to me and as his wife she can just take it anyway.  <response>: I just dont agree with people that you should just sit on your hands and let whatever happen. If putting some minimal amount of effort into this returns you thousands of dollars in the future then you should do it. If your fathers wish is to leave everything to you then you should do everything you can to make sure he and you dont get robbed of that by some asshole.
