If the will, whether or not it says "draft" in it, was properly signed and witnessed, then it is valid and enforceable. If it was not properly signd and witnessed--which in your state (and every other state with which I am familiar, for that matter) that means you have to sign it in front of two witnesses, who then each sign in front of each other--then it is not valid or enforceable.If a will is valid, it can only be revised or amended in the same way it was created in the first place: by adding a page (a codicil or amendment) which is signed and executed like a will. Simply initialling a change is in no way legally binding.
