You have a very tough situation. It is not clear HOW your sister has control, so it is tough to know where to start. If your parents changed their estate plan to provide solely for your sister, and if they had the capacity to do so, then there is little you can do. It is possible that there were reasons for this, which you would know, but did not share. It is also possible that your sister totally took advantage of the situation and is now making bad decisions. What is clear is that you cannot handle this on your own. Your options are limited, and if your sister does not agree with you and cooperate, which sounds unlikely, the only real choice you have is to try to go to court. It may be that your sister has full control and there is nothing you can do. It may be that your sister has control of the assets, but the court could decide to give you guardianship/conservatorship over your mother. You need a lawyer to assist you with this, both in terms of investigating what has been done, as well as to determine how best to attack it, if that can be done. Unfortunately, it is likely this would be a contested matter and your sister will make it very expensive for you.
