It is also possible to sue for divorce without the other party's ID card and marriage certificate. As long as you can provide the ID number of the other party, your own ID card, marriage certificate, household register, etc., you can file a divorce lawsuit. The ID card of the other party who is suing for divorce is not necessary, but the identity information of the other party is required.
