I have been the sole care provider for my father for 20 plus years. Several years ago he made a will and decided that he wanted to leave me the property that he and I reside on. Now he is more ill and my siblings come and go as they please but do not take care of him. They do not take him to doctor's appointments etc. I am his sole caretaker, now they want him to change his will because he's getting more ill, and they want the land to to be divided 4 ways. Can I fight them and am I entitled to the property that was left to me in the will?
