An interesting topic, but - on this subject matter - might I take this opportunity to suggest, or to recommend, to everyone (especially those who may have assets) that they take the time and trouble to prepare (and have witnessed by a lawyer) a will, even if it is only two lines in length.
You will save your relatives/family/friends - those to whom you wish to leave assets - a lot of grief, both metaphorically and literally, (especially when they will probably not need further complications on your death) if you do so.
Relatives of my mother, two of her siblings, both unmarried, - well, one a widow without children, the other a clergyman - both educated, intelligent, well-read and widely travelled people, died intestate. Candidly, it left a bit of a mess, (not that anything was contested), one that took years to fully clear up.
