I don't know the Washington state laws in the future, but now in the State of Pennsylvania, Notaries Public have to keep a contemporaneous record book of all uses of their seal. In most cases, wills have to be witnessed, but I don't know if Notarization is required.
Maybe the fake will is holographic, entirely in the Dr.'s handwriting, but how was it possible to have time to get it to India without giving the Dr. a chance to have a more recent will written? The Indians' lawyer was entirely unprepared with any details.
