Necrogamy or posthumous marriage is a marriage of two parties where one is deceased at the time of matrimony.
Most cases of necrogamy occur in France and China, as far as I know.

I don't see the use. It's allowed in France law but under extreme cases, the President has to actually give his consent for such an act to occur and the marriage has barely any effect except for the widow to carry her deceed "husband"'s last name.1
