Hello, according to the situation you described, first go to the neighborhood committee to apply for mediation, see if you can get the marriage certificate back and if there is still room for the marriage to turn around. After mediation fails, you can file a civil lawsuit to the court for divorce. Use legal weapons to protect your rights and interests. Remember not to use the method of delaying divorce. After two years, the method of automatic divorce does not register divorce, It is legally bound by the marriage law, unless you can guarantee that people will not harass you in the past two years, and your life will always continue. If you have a lover in the past two years, the other party has exact evidence that you committed the crime of cohabitation or bigamy, and later divorce proceedings will become a stain.
