I prefer the truth and clean way of having an annulment. I can be sure, no husband will be "ressurected" and claim me back.
Sometimes ex husbands do the hiding VOLUNTARILY due to their mistress .or he is abroad, with fake identities.
Despite all the waiting of Uri, its serves best. Sally is free to remarry for the rest of her life with out another "goonie husband " to blackmail her in the future if she choose that law of presumptive death.
That law for me is: Silly.
