My mother was placed into assisted living three months ago. My sister and I decided to start cleaning out three levels of a large house. My sister started claiming the property that was very expensive, antiques and collectibles. When the day was over I listed what she wanted compared to about a half a box of things that I had requested. I realized it was unbalanced and unfair. Aside from specifics bequeathed to us, all was to be shared. My sister threw a fit! She said mom knew that she always wanted those. There were three large boxes of expensive hand-painted Christmas ornaments and she was not willing to give up even one of them. It was insanity! Mother was very generous with her in the will. When I calmly explained that mom wanted things to be split she started yelling at me and saying that if I live in the house I'm living basically for free. She deserves what she wants. I only offered to live in the house because I didn't want it to sit empty. I can see what things are going to be like when Mom passes and I am the executor of the will. I don't want to be executor because my sister is manipulative and has always thrown big fat fits and gotten very mean if she did not get what she wanted, therefore she always got what she wanted. How do I change the executor? Mom has Alzheimer's and is incompetent to do this. My sister and I have dual power of attorney.
