Recently I got a question whether Korean court permits international divorce when both parties are foreign nationals. The questioner was in a situation that she lived in Korea but the spouse did not. Here is a short and general answer:
In principle, Korean court permits international divorce case only when the defendant has a residence in Korea. The court, however, in a rare case permits the case if (i) the plaintiff fails to locate the defendant or (ii) the defendant who has no residence in Korea answers the lawsuit filed in Korean court.

This is quite natural that if both the parties are from different countries, Any particular 3 rd resident country can,t do justice. because Law of every country is different.
