Rio de Janeiro state Judge Benedicto Abicair says that Marcelo de Azevedo Fernandes must pay for "moral and material" damages to Cristiane Costa de Andrade. The ruling was posted Friday on the court's website.
The couple was to have been married in September of 2007, but Fernandes called it off.
The judge says that Andrade's "suffering, anguish and humiliation cannot be ignored."
The fine is supposed to pay for the jilted woman's wedding costs and visits to a psychologist.
