I have recently bought a book called ‘When I’m Gone’. Do not give this one as a present though!
It contains questions about your life and you can leave letters in it for loved ones to let them know your thoughts on them. Also where your Will is and details of bank accounts, insurances, financial information, final wishes re burial/cremation etc and loads more which will be helpful to your family & friends and executors of your Will. You can see why you wouldn’t want to give it as a present but it had so many questions in there that I had not thought of. You would have to tell someone where it was but you can keep updating it. Sorry not so happy a thought but may prove useful to someone getting their papers in order and as my husband has dementia he has done one too which he can refer back to.
