No-one can avoid death or taxes but Ken Dodd at least managed to minimize the latter in his final days. The key of course was marrying his long-time partner and instantly getting the benefit of total exemption from inheritance tax as a result of the spouse exemption. He would of course have had to make a will immediately after the marriage, or may be just before but in contemplation of the marriage, because otherwise Ken’s late entry into matrimony would have cancelled any previous wills, even if they were in favour of the partner.
Are there any morals to be drawn? Probably not, but clearly the desire to save tax often wins over the reluctance to get married.
