I think it is not just a death folder but more an "End of Life" folder because death can be slow.
Both my parents had Dementia so we had to take care of everything. Luckily we had arranged LPAs but we needed access to finances at the point where they were no longer able to do it for themselves
Care wishes are important. Are you happy to be placed in a home or do you want care at home?
On death, plan your funeral as much as possible before.
The number for the undertaker
Number for the registrar
Where the service is to be held
Cremation or burial or direct cremation
What do you want done with your ashes
Music if you are having any
Who is to be invited or are
Even, if you feel you can have an idea of what you want to wear.
What insurance policy is to be used to pay for the funeral
All of these decisions can be so heartbreaking I think the easier you can make it for those who take it on the better.
Even putting instructions on what to do can help because when someone gets sick and then passes it can be such a massive learning curve at the most stressful time.
Probate can be a minefield. This is a useful link to put in or print off because it is a quick guide on what to do and in what order. I was talking about this the other day. It would be helpful if we had all the details pulled together for probate before we died so the executor of our wills could copy, and paste it into the documents.

This is a great idea though because I know too many people who are having a very stressful time managing the administrations of parents who are coming to the end of their lives and do not have anything organised.
