[How to divorce in Korea] International Marriage Fraud: Why Annulment, Not Just Divorce, May Be the Right Legal Response

  After entering into an international marriage, some individuals find themselves facing situations very different from what they had expected. In cases where international marriage fraud is suspected, it is important to look beyond simple conflicts or personality differences and consider whether the relationship itself may have been fundamentally flawed from the beginning.   In actual consultations, many people who initially seek to file for divorce from a foreign spouse only come to recognize the possibility of marriage fraud over time.   If patterns such as sudden loss of contact, repeated financial demands, or a complete breakdown of the relationship after the spouse achieves their residency goals are observed, the situation may go beyond a typical divorce involving a foreign spouse and instead warrant consideration of an annulment.   Because the outcome can vary depending on how the case is framed from the outset, obtaining an early assessment from a lawyer experienced in international divorce is critically important.

1. Key criteria for identifying international marriage fraud: the original intent matters most

  When determining whether an international marriage constitutes fraud, the most important factor is the sincerity of intent at the time of the marriage.   Simply having problems arise after the marriage does not automatically mean it will be recognized as marriage fraud. Courts focus not on what happens after the marriage, but on the intent at the time the marriage was formed.   For example:
  • leaving immediately after the marriage without living together
  • making repeated financial demands
  • cutting off contact after securing residency status
If these patterns appear repeatedly, the likelihood of international marriage fraud increases.   In such cases, approaching the matter as a standard divorce involving a foreign spouse may be disadvantageous. Depending on the circumstances, pursuing an annulment may be a more appropriate legal option.   Therefore, it is important at an early stage to assess the nature of the case with the help of a lawyer experienced in international divorce.    

2. Divorce vs. annulment in international marriages—the choice can change the outcome

  Many people do not clearly understand the difference between a divorce involving a foreign spouse and an annulment.   If international marriage fraud can be established, pursuing an annulment rather than a standard divorce may lead to a more favorable outcome.   In addition, if the case is handled as a typical divorce involving a foreign spouse, issues such as property division and alimony follow the same structure as ordinary divorce cases. However, in annulment cases, the focus shifts to restitution of unjust enrichment or claims for damages.   Understanding this distinction is crucial, and making the right judgment is an area where the role of a lawyer experienced in international divorce is particularly important.    

3. When service by public notice is necessary: cases involving loss of contact

  One of the most common issues in international marriages is loss of contact.   When a spouse returns overseas and can no longer be reached, it can become difficult to proceed with a standard divorce involving a foreign spouse. In such cases, a legal procedure known as service by public notice is often used.   Service by public notice allows the court to complete the service of legal documents through a formal process when it is not possible to deliver them directly to the other party.   In situations involving suspected international marriage fraud, it is common for the other party to intentionally cut off contact, which is why this procedure is frequently utilized.   Even in this process, a strategic decision must be made—whether to proceed as a standard divorce involving a foreign spouse or to pursue an annulment instead.   For this reason, having a well-planned legal approach with the guidance of a lawyer experienced in international divorce is especially important when proceeding with service by public notice.    

4. What matters most in proving a case for annulment

  An annulment cannot be granted based on simple claims alone.   In particular, to prove international marriage fraud, objective evidence is essential.   Key supporting materials may include:
  • immigration and travel records
  • records of financial transfers
  • messages and communication history
  • evidence of actual cohabitation (or lack thereof)
  • promises made before and after the marriage
  These materials should not simply be listed, but rather organized in a structured way according to a clear timeline.   Unlike a standard divorce involving a foreign spouse, the burden of proof in an annulment case is significantly higher, requiring a more strategic approach.   Ultimately, in international marriage fraud cases, the outcome can vary greatly depending on how the evidence is organized and presented.    

5. Whether to end with divorce or pursue a strategic legal approach requires careful judgment

  Many people want to resolve their situation quickly through a standard divorce involving a foreign spouse.   However, if international marriage fraud is suspected, simply ending the matter through divorce may actually be disadvantageous.   In particular, it is important to consider an annulment in the following situations:
  • when there has been financial damage
  • when there are suspicions that the marriage was for immigration purposes
  • when there are repeated signs of deception
  It is also crucial to determine the right approach—whether to proceed alongside service by public notice or to move directly toward an annulment.   Because divorce involving a foreign spouse, international divorce litigation, and annulment all lead to different legal outcomes, making a strategic decision is essential.   Ultimately, the key issue lies in how the suspected international marriage fraud is legally structured and presented.   International marriage fraud is not simply a marital dispute—it fundamentally changes the legal framework of the case.   Whether to resolve the matter through a standard divorce, pursue a divorce lawsuit, or proceed with an annulment can lead to completely different results.   In particular, if contact with the other party has been lost, service by public notice must be utilized, while also examining the possibility of proving marriage fraud.   All of these processes are not separate, but interconnected. Therefore, setting the right direction from the very beginning is critically important.       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   How to find a divorce lawyer?
