It is messy and expensive if someone dies without having a will. The lawyers get the bulk of it.
Try talking about it to your dad, even if you broach it in a roundabout way first.
My parents are the opposite. Not only do they both have wills but they have planned their funerals and mum and I are going to design their service sheets too. She is currently picking the pictures she wants shown on a slide show during the service, plus working out which ones she would like on the service sheet. They have also asked who wants what and all 4 of us know what mementos in particular are wanted by which sibling.
Of course, I do not see why any child expects to get anything from their parents' when they die. It is not a right.
My kids have been warned we are spending all our cash and they can fight each other over the assets (if we haven't sold them all off as well) :thup:
