"dispose of your assets"? What do you mean? Where I live, there are pretty straightforward rules for inheritance. Even if I don't make a will, my assets won't be disposed of but will go to my relatives in a very specific priority order. I'm not debating whether people should make a will if they want their assets to be distributed in a specific way, in which case they definitely should. But if there is no will, there are still clear rules for which relative gets what. Are there any places where this is not the case?
