The painful admin after someone dies

Someone has died and now there is a pile of accounts to close, which is the last thing you want to deal with. Give it the organisation, the deceased's name, the account number and your relationship, and it writes a respectful, minimal letter notifying them of the death and asking them to close the account, with a list of the documents to enclose.
