Case Xiao Zhang and Xiao Yang were introduced to each other, fell in love at first sight, and registered for marriage a month later. Shortly after the marriage, Xiao Yang found that her husband, Xiao Zhang, suffered from serious mental illness and took a variety of drugs every day. Fearing that he was hurt, Xiao Yang applied to the court to revoke his marriage on the grounds that Xiao Zhang had not informed him of his illness before marriage. Can the marriage between Xiao Zhang and Xiao Yang be annulled? It can be explained by cases. Article 1053 of the Civil Code stipulates that if one party suffers from a serious disease, it shall truthfully inform the other party before marriage registration; If he fails to tell the truth, the other party may apply to the people's court for dissolution of the marriage. A request for dissolution of a marriage shall be made within one year from the date on which the person knew or should have known the cause for dissolution. (Liu Xinshe)
