I'm a bit upset with my dad over his recent change of giving medical POA and durable POA to my step-sister instead of me as his only child. They have put together a joint will instead of separating anything out for me if he were to die first. He says it's written up such that if he dies before her that everything will go to her and then upon her death the estate will be divided up between myself, my step sister, who has been made the executor of the estate, and my step brother. This leaves the possibility, I think, of my step mother writing me out of her will once my dad dies. He will not talk about this over the phone. All he says is that my step-sister is totally in charge now. I don't really trust her anymore than I do my stepsister for they are both opportunistic, dominating personalities and my step mother has been jealous of me my entire life. Any ideas about what I can other than just mentally cut my losses before they happen and move on with my life.
