Both men and women who want to get married should apply for marriage registration in person at the marriage registration office. Those who meet the requirements shall be registered and issued a marriage certificate. Marriage registration is the establishment of marriage relationship, so a marriage certificate is enough.

Legal basis: Article 1049 of the Civil Code of People's Republic of China (PRC) requires married men and women to apply for marriage registration in person at the marriage registration office.
