BG5150, I would add that of course the disclaimer is the responsibility of the person who is doing the disclaimer and his/her counsel. A lot of widows and widowers don't, of course, usually have counsel, but a business owner who is dealing with the estate of his or her spouse likely does, so if it were me I would make sure that that counsel drafts the appropriate document(s) and takes responsibility for requirements' being met and advising on what the outcome of the disclaimer will be.
