The will is the main dispositive document that you draft up in order to tell the world this is how I would like my assets to be distributed on my passing. My probate assets. A codicil is simply an amendment to that will. In this day and age, we don’t use codicils quite as often, why, because we have word processors that allow us to just redraft the will completely without very much difficulty. There was a time when codicils made a lot more sense than they do now in that you didn’t want to have to redraft an entire will just to make a small change. But now that redrafting is rather quick and easy.
