Christel Demichel, who wore black, was married Tuesday under a little-used law in the presence of friends and relatives at city hall in the southern city of Nice, local officials said. It would have been her husband Eric's 30th birthday.
"Eric and I promised when he was alive that we would get married," she told French television. "Even though he is dead, I respect the values I shared with him, especially as his death was not his fault."
Eric Demichel, a policeman, was killed in a hit-and-run car accident in September 2002. Christel, who was pregnant at the time, lost her baby in the same accident.
"I lived a beautiful love story and this wedding testifies to it," Demichel said.
Posthumous marriage is allowed in France under a law introduced by former President Charles de Gaulle.
