We had a friend of my MIL who made a will and left a copy with a local solicitor leaving everything to my MIL or my husband as he had fallen out with his family years ago. When my MIL died suddenly of cancer, although my DH tried to be helpful to her friend, he was somewhat of a recluse and so, struggling with his own grief, DH backed off. One day, within a year of his Mum's death, he suddenly noticed the house was for sale so I went to the Estate Agent to ask which home the gentleman was in. That was when we found he had apparently died intestate, The Crown's Solicitor had put it on the Intestacy List and one these Heir Hunters had tracked down his supposed list. Nobody had contacted the solicitors in our small town and it turned one of them had the will. I was staggered to find that it is not incumbent on the authorities to check more thoroughly. Even the neighbours they'd checked with had explained they were new to the area but the rest of the street were long standing residents who knew each other well. Had they asked at any other house, they would have found that the Gentleman definitely had a will and would have known the solicitor too. Instead, they had heirs who weren't really heirs so felt they'd been fleeced and the real heir who knew that there were 'treasures' that were definitely missing by the time he knew about it. I think you should be required to register a will at a central place in order for it to be valid and have to go through a process to ensure you remove it if you change your mind.
