I was told that a Trust had to be a maximumm of FOUR people.
My ex-hubbie was also told this when he wanted to set up a Trust in his will for our five children.
Several years ago, when I got rid of my home office, afind threw out the filing cabinets as they were ugly. I purchased a tall slim, very sturdy Ikea drawer unit. five shallow drawers and four deeper ones. THIS is now my filing cabinet. So all paperwork is easy to see and to find. One of these files is the deeds t my flat plus all infrmation that the Solicitor may requre when it is being sold. A further file in one of the drawers contains my will (my AC all have a copy of this), plus birth, deed poll, marriage, divorce etc certificates. A book kept near to my laptop (An A-Z directory) contains all my passwords etc. My children all know and understand the code I use for my credit card numbers, etc.
I agree that we really should try to make it as easy as possible for our AC, when we die. No matter how old we will be when that happens, it will be a difficult time for our children, and at least we should do whatever we can to make it as simple as possble
