I want to make it as easy as possible for those left behind - especially my children.
First of all, do you have a Will? Does your Executor have a copy or know where to easily find it?
I have a letter attached to mine with my wishes for my burial. There was an AMA from a funeral director recently which was beautifully enlightening.
Is your Emergency Contact details up to date at your DC's school / your place of work?
I also have in the folder with my Will a copy of my Life Assurance Policy. I've not written down any passwords but have a note of my bank account details, premium bond numbers, online ISA account numbers, NI number, old pension pots etc. The issue is updating it if you change suppliers.
Who would look after your DC if, for example, you needed to be in hospital for a month following an accident. Do they know about any allergies/ medicine, favourite food, favourite bedtime story/bunny etc?
Does your friend have a copy of your house key, or know where one is hidden, so they can collect clothes etc for you / your DC? Write down where the water stopcock is and any alarm code.
If you keep cash or valuables in the house, allude to where. Try and prevent someone throwing away a manky vase that is actually a valuable antique.
Last thing is a list of people, maybe your Christmas card list, that you would want to be contacted to be told you were hospitalised / had died. Would you prefer a note to be sent or a Facebook announcement?
If you have time, poleroid photo your favourite jewellery / sentimental items and write on the back why they are special for you. It's this kind of personal information that's lost when you die. Maybe also favourite recipes or a note of your favourite films and books.
Once all that is done, sit back and enjoy a long and healthy life!
