In France, it is legal to marry a dead person!
Posthumous marriage is a marriage in which one of the participating members is deceased. It is legal in France and similar forms are practiced in Sudan and China. Since World War I, France has had hundreds of requests each year, of which many have been accepted.During World War I, a few women were married by use of proxy to soldiers that had died weeks earlier. This practice came to be called posthumous marriage. Posthumous marriage for civilians originated in the 1950s, when a dam broke and killed 400 people in Fréjus, France, including a man named André Capra, who was engaged to Iréne Jodart. Jodart pleaded with French President Charles De Gaulle to let her go along with her marriage plans even though her fiancé had died. She had support from the media and within months was allowed to marry her fiancé. It is likely that posthumous marriage was made as an extension to France’s Proxy Marriage
