You could also use a simple one-time-pad here to split the password. Generate two alphabetic passwords, one for your attorney and one for a trusted friend. Actual password is these mixed with alphabetic rotation character-by-character (anyone ought to be able to figure out how to do this given a short guide). Simple, and provably useless to an adversary unless they have both passwords (aside from knowing password length/format with one).
