Slightly morbid but what information do I need to have available in case of my death?

[Hermanfromguesswho]

I am a single parent and I have been thinking recently about having any relevant information all together and with a trusted friend in case anything were to happen to me.
Things like life insurance policy details, car/home insurance, savings, mortgage etc. I was thinking my passwords may be useful too such as email, phone, online banking etc.
Has anyone done this? Is there a list of things to include? Would you put in details of bills and services I use/have on direct debit?

i have done this in light of a terminal diagnosis i have no relatives so absolutely everything will be done by solicitors. Does worry me a bit that no one I actually trust will be dealing with it, but having seen the stress a friend was under dealing with someones estate I couldnt put it on them.
All my bills etc are on line so I suppose my password will be needed, hadnt thought about that. Its remembering to update as things change that is the problem.

I don't have paper copies as nearly everything is electronic apart from my Will. Make sure you have a password-protected folder (mine is in my email account) which contains links and useful information for whoever will be dealing with your affairs. Update it regularly particularly for any investments. My daughter has my email password and I'm comfortable that everything she will need is easily accessible.

I had an ectopic and in the words of the surgeon I got lucky. So whilst recovering I had a good think and it dawned on me that h knows nothing about the domestic / financial side. So I wrote a letter and gave it to my sister. I trust her not to open and keep safe. I update as and when. It lists accounts and savings as well as bills and how often they need to be paid. School details and sen details too for the eldest. I must admit I hadn’t thought of recipes. Oh and I should include a note of my two treasured processions which are not worth money just sentimental so my boys understand.
Ps it’s not morbid it’s being practical. When my grandfather died everyone was wondering whether he wanted burial or cremation- there was relief all round when i spotted a note in his will with his wishes.
