Part of why it took me so long to go NC with my parents was because of the inheritance issue. That immediately sounds awful, I get that, but try to understand; material objects were long a primary source of my mother's control over me, and she spent a great deal of time and effort instilling and reinforcing those values in me. What's that one saying? It's easy for your parents to push your buttons - they put them there.
My mother showed her approval with baubles and gifts, and she often showed her ire by smashing my belongings or threatening to. She bought me things I didn't ask for and didn't want or even like, had never expressed any interest in in any capacity whatsoever, and turned a hateful gaze on me for not being excited enough when she pulled them out of the bag. When she was happy with me, she was generous. When she was devaluing me, I went without. I learned to associate love with materials and gifts. When I grew older, she would give gifts to my friends and tell me about them later and ask if I was jealous, growing obviously disappointed or even hostile if I didn't act appropriately mournful to have missed out. I don't think it could be considered surprising that I ended up stuck at the door of going NC, dreading the thought of her inevitably getting in one last jab when she finally does kick it - "look, I may be dead, but just so you really get the message: this is how I feel about you."
There's a very real chance she will send all her belongings off to the trash heap and the money off to support some cause she doesn't care about simply because it's contrary to my personal views and values. I sincerely hope so, anyway. I don't really want any reminders; her gifts always had too many strings anyway.
