My Uncle passed away several years ago. I was the only relative that lived near by, that had any type of relationship with him, and I took him to all of his Dr.s appt.s, etc.... He assumed that I would inherit anything that was left after his passing. I didn't ask for anything, but he told me that I could have what I wanted. He never put any of it in writing. After his death, all of the sudden I had cousins I didn't even know existed! I received 1/5 of what he intended. I wouldn't have minded, if that had been his wish. But it was not.
After that, my last remaining parent had a short but sweet will made up for about $75. I was the caretaker, so that was taken into consideration. I was made Power Of Attorney and anything that was to be mine, or my siblings, was put in writing then and there. There was also some exclusions. The comment was made that they were loved and thought of, but due to a lack of personal contact, they would not be receiving an inheritance from the estate.
It left no arguments or hard feelings.
