I think endings are the hardest things to do - epecially for us in the west, who invest in staying young and avoiding the gracefulness of old age. All of our cultural drivers seem to be around maintaining things around us and within us and trying not to think about the time-limited nature of everything. Consequently we become obsessed with trying to control things, sometimes to the effect that we don't enjoy what we have.
I think the families that have most problems with money and things following a death are the families that are most interested in things, rather than relationships. People invest huge amounts of time ingratiating themselves with older members to try and "get" things from them after their death. The aquisition is the important things rather than the person.
A previous partner had parents like this and it made me feel disgusted to see how they treated his grandfather - I thank god I didn't marry into that family!
