If a spouse returns to their home country shortly after marriage and all contact is lost, is it still possible to proceed with an international divorce lawsuit? Recently, cases involving marital breakdown and loss of contact after international marriage have been occurring steadily. In particular, when the other party’s address is unknown and communication is impossible, many cases remain unresolved for long periods simply because people are unsure how to begin the legal process. International divorce litigation is not merely about ending a relationship. It is a procedure that requires careful consideration of jurisdiction, methods of service, and the structure of legal proof. Today, we will explain the service by public notice system, which plays a key role in international divorce cases, and examine real case examples of successful outcomes. Through this, we will outline how situations involving a spouse who cannot be contacted can be addressed in a structured way.

1. If a spouse returns overseas and contact is lost, is it still possible to file an international divorce lawsuit?

An international divorce lawsuit can still be filed even if the other spouse does not reside in Korea. However, if it is not possible to serve the complaint through the usual method of document delivery, the court requires the use of service by public notice, following procedures determined by the court.

CHECK POINT
Long-term residence overseas
When it is difficult to verify the spouse’s address
Complete loss of contact
When communication through phone, messaging apps, or acquaintances is no longer possible
Unknown whereabouts
When actual residence cannot be confirmed beyond immigration records
Possible solution
Proceeding with the case through service by public notice

An important point here is that a lawsuit does not become impossible simply because the other party cannot be contacted. However, it is necessary to demonstrate that sufficient efforts were made to locate the spouse. If this preparation is not properly completed, the court procedure may be delayed.

i
Procedural preparation is important in international divorce litigation.
The inability to contact the spouse does not itself prevent a divorce lawsuit, but objective evidence of efforts to locate the spouse may affect the progress of the procedure.

2. What is service by public notice in international divorce litigation?

Service by Public Notice (공시송달) is a method of service exceptionally recognized by the court when the other party’s address cannot be identified. In litigation, the procedure can proceed only after the complaint has been delivered to the opposing party. However, if contact has been lost after the person returned overseas, ordinary service becomes impossible. In such cases, the system used is service by public notice.

This is a procedure in which the court acknowledges the effect of service after posting the notice for a certain period of time. It is frequently used in lawsuits involving lost contact or unknown whereabouts of the opposing party.

PROCESS
Preparations Before Proceeding
1.
Conduct an immigration and departure record inquiry
2.
Provide proof of efforts made to locate the individual
3.
Secure records of returned mail
4.
Apply to the court for service by public notice

An important point is that service by public notice is not automatically approved. The key issue is whether sufficient efforts were made to locate the opposing party and whether those efforts can be proven with objective evidence. Therefore, it is not simply a matter of filing an application; it is a procedural strategy that requires proof and supporting evidence with a divorce lawyer in Korea.

The court recognized the spouse’s fault in the breakdown of the marriage and accepted the procedural legitimacy of the case. This matter demonstrates that service by public notice can serve as a practical legal solution in litigation when the opposing party’s whereabouts are unknown. This is not merely a matter of ending a relationship. If fault can be clearly established, a claim for alimony (compensation for damages) is possible.

CHECK POINT
Unilateral return to the home country
Immediately after marriage
Long-term loss of contact
Continued inability to communicate with the spouse
Complete cessation of marital cohabitation
Failure to maintain a marital relationship
Emotional and psychological harm
Damage suffered due to the breakdown of the marriage

In this case, these factors were considered collectively, and 10 million KRW in compensation was awarded. This process is not simply about dissolving a relationship, but about clearly establishing the responsibility of the at-fault spouse and restoring the injured party’s economic rights as well.

4. What is the most important factor when preparing for an international divorce lawsuit?

The most important factors are securing objective evidence and understanding the procedure. In international marriage litigation, the structure of proof is more important than mere allegations. Courts generally examine three key elements:

CHECK POINT
The cause of the marital breakdown
The responsibility of the opposing party
The procedural legality of the case

If even one of these elements is insufficient, the case may be delayed. In particular, when service by public notice is required, the outcome is often determined during the preparation stage.

PROCESS
Preparation Items
Immigration records
Confirmation of the date of departure/return
Communication records
Call logs, text messages, messenger records
Returned mail records
Proof of unsuccessful service
Background of the marriage
Clarification of responsibility for the marital breakdown

Service by public notice is not automatically granted. It must be demonstrated that sufficient efforts were made to locate the opposing party. If this is lacking, the litigation may become prolonged. This is not a matter of emotion, but rather a matter of evidence and legal procedure. Especially when service by public notice is required, it is crucial to establish the correct evidentiary and procedural structure with a divorce lawyer in Korea from the very beginning.

5. How is international divorce litigation different from an ordinary legal divorce process?

We have accumulated numerous successful cases involving service by public notice in situations where a spouse has lost contact. What is more important than simply asking whether a divorce is possible is how the case is prepared and structured.
