Having just gone through this with my FiL dying suddenly and unexpectedly, I had no idea of the range and scope of things that had to be addressed. Even things like MiL’s car had been bought in his name – ownership has to be formally transferred before she could sell it. Also insurance documents in his name (house, car etc) are not valid until transferred to her. There was a lot more to do besides the obvious stuff like banking, credit cards, pensions, shares etc, and all of this required locating the correct documents before working through the processes. Wife and I both have wills but it made us think about the need to have all papers properly organised and accessible for whoever is going to have to sort it all out one day
