Foreign Spouse Missing or Fraud Marriage? Here’s the Procedure You Must Check First

  Even if you married for love, being left alone in the end can make anyone feel completely lost.   Marriage to a foreign spouse does not always lead to happiness.   Differences in lifestyle, values, or sense of responsibility can cause the relationship to break down in a short period of time.   The real problem arises when, in a divorce involving a foreign spouse, the other party has unilaterally left the country or cut off contact. In such cases, not only is reaching an agreement nearly impossible, but there are situations where the court proceedings themselves cannot even begin.   If you have no way of knowing your spouse’s whereabouts, you may proceed with the lawsuit through public notification (공시송달), but the requirements and procedures are so strict that it is very difficult to handle alone.   On top of this, cases of fraudulent marriage, where a foreign spouse disappears after registering the marriage solely to obtain a visa, continue to increase. Depending on the circumstances, you may need to consider annulment of the marriage, rather than divorce.   In such a complex situation, if you wish to legally bring your marriage to an end, it is best to carefully review which procedure applies to you now together with a legal representative.

1. A Case of Completing Divorce Through Public Notification When the Foreign Spouse Was Unreachable

  The client, a Korean man in his early 40s, married a Mongolian national about six years ago and built a family together in Korea. They had a child and lived as a family, but one day the spouse left for Mongolia, saying she was visiting her hometown—and never returned.   As the visa expiration date approached and all attempts to contact her failed, the client was forced to continue raising the child alone.   Under these circumstances, pursuing an amicable divorce on his own was no longer realistic.   Even while preparing for litigation, he could not identify the spouse’s whereabouts, making it impossible to serve the divorce petition.   Ultimately, with the assistance of a legal representative, he applied to the court for public notification service (공시송달).   Using immigration records, text messages, emails, and other materials, the attorney proved that locating the spouse was impossible.   The court accepted this evidence and approved the request for public notification.   The case proceeded as scheduled, and the court granted the divorce while also awarding the client sole custody of the child.   As a result, the client was able to legally finalize the end of the marriage.    

2. Why Legal Representation Is Essential in Divorce Cases Involving Foreign Spouses

  As seen in the earlier case, preparing for a divorce involving a foreign spouse requires much more than simply identifying the grounds for divorce.   If your spouse is a foreign national, you must first determine whether the divorce lawsuit can be filed at all, and then examine which country’s law applies—Korean law or the spouse’s home country law.   Under Korea’s Private International Law, if the center of the marital life was in Korea, the divorce case can be heard in a Korean court, and Korean civil law will apply.   However, in real cases, there are additional issues to consider:
  • Whether the spouse’s current residence can be identified
  • Whether foreign law might apply due to specific circumstances
  • If there are children, how their nationality and living environment affect custody decisions
  Beyond custody, practical issues such as property division, compensation for emotional damages, and other financial matters often become intertwined.   Setting a clear legal strategy from the very beginning can prevent unnecessary loss of time and cost.   To avoid prolonged procedures or unexpected complications, it is safest to work with a legal representative early on and establish a complete overview of the case from the start.    

3. If Your Spouse Cannot Be Reached, You Can Proceed Through Public Notification

  Even if you wish to file for divorce from a foreign spouse, an amicable divorce is no longer possible if the other party is overseas and completely unreachable.   In such cases, you must switch to a court-based procedure. However, if you do not know the spouse’s address, it becomes impossible to serve the petition, and the lawsuit may come to a halt.   The solution available in this situation is public notification service (공시송달).   Public notification is a legal procedure in which documents are posted in an official manner and are deemed served by law, even without direct delivery.   However, the court will only accept this method if the following requirements are met:
  • The spouse’s residence or whereabouts cannot be clearly identified, and
  • Despite attempts through various means, actual service is realistically impossible, and
  • You can prove that you gathered objective and sufficient evidence to locate the spouse, and that these steps were carried out lawfully.
  Once these conditions are satisfied, the case can proceed normally, and the divorce process can continue to completion, even if the spouse’s whereabouts remain unknown.    

4. If You Suspect a Fraudulent Marriage, You Should Consider Annulment Rather Than Divorce

  If you are considering a divorce from a foreign spouse, it is important to determine whether the issue is simply marital conflict or whether the marriage itself was never valid from the beginning.   If the spouse disappeared shortly after the marriage registration and never fulfilled any marital duties or responsibilities, it may be viewed as a situation where there was no genuine intent to marry.   In particular, if the spouse registered the marriage solely for the purpose of obtaining legal stay in Korea and never began an actual married life, this may constitute a fraudulent marriage.   In such cases, the appropriate action is not a standard divorce but a marriage annulment lawsuit, a legal process to confirm that the marriage never truly existed.   However, the burden of proving the lack of marital intent lies with the petitioner.   Therefore, you must collect sufficient evidence such as immigration records, social media conversations, and statements from family members or acquaintances that support the circumstances.   Because the procedure is complex and the legal standards are strict, it is advantageous to seek professional legal assistance early on and take a strategic approach from the start.    

5. Divorce with a Foreign Spouse Can Be Risky to Handle Alone

  If your relationship with a foreign spouse has effectively come to an end, you should not delay any further—you need to review the appropriate legal procedures for your current situation.   The first step is determining whether the matter can be resolved through a straightforward divorce filing, or whether it involves a fraudulent marriage, where there was no genuine intent to marry from the start.   If the spouse is overseas or unreachable, you must also consider additional procedures such as public notification service (공시송달).   In such complex situations, setting the right direction from the beginning is crucial.   A Korean Bar Association–certified family law specialist with real experience handling fraudulent marriage cases, marriage annulment lawsuits, and public notification proceedings can provide the most appropriate strategy for your situation.   Divorce involving a foreign spouse cannot be resolved simply by expressing a desire to separate.   Because you must evaluate the validity of the marriage, select the correct litigation method, and prepare supporting evidence all at once, it is far safer to seek professional guidance rather than attempting to navigate this alone.     Multilingual consultation available in English and Chinese.   Professional interpreters assist from the first consultation to the conclusion of the case.   Offices in Seoul, Daejeon, Busan, Daegu, and Gwangju   Don’t face the legal system alone.
