I've just been into my 'Documents folder', looking for a copy of my own will in order that I could modify it in response to your question. To my amazement (because I'd completely forgotten that I'd created it), I found a file there, dated 18 January this year, called 'DraftWillForCaran.doc'. So it seems that I must have answered this question before!
Go here, and click the 'Download' button, to access the file and then open it in Word (or whichever other word processing software you use):

[Note to others: There's nothing at all confidential about that file; it's simply a generic draft document. If you'd like to take a look at it as well, please feel free to download it].
