If you have lost contact with your foreign spouse, divorce by agreement is no longer a realistic option. When the other party does not cooperate or cannot receive necessary documents, you must first determine whether you can proceed with a foreign spouse divorce lawsuit in Korea.
At this stage, it is not just about filing a complaint. You must first review three key issues to ensure that the case can officially move forward:
- ① Whether the case can be handled by a Korean court,
- ② Which country’s law should apply,
- ③ Whether there is a viable method to serve documents to the other party.
If all contact with your spouse is completely cut off, you may need to use a procedure called public service of process. However, this process has strict requirements and involves legal review, making it difficult to handle alone.
If you wish to formally resolve your marital relationship, it is safest to consult with an international divorce attorney at this stage and establish a clear strategy moving forward.

1. Three things to check before filing a divorce lawsuit against a foreign spouse
A divorce lawsuit involving a foreign spouse cannot begin based on emotion alone. To formally proceed, you must first confirm three essential conditions: the applicable law, the method of proceeding, and the possibility of serving documents to the other party.
01: Determining which country’s law applies: Choice of Applicable Law
Under Korea’s Private International Law:
- ① If both spouses share the same nationality, the law of that country applies.
- ② If they have different nationalities, the law of the country where they lived together applies.
- ③ Otherwise, the law of the country most closely connected to the marriage applies.
If one spouse resides in Korea, it is highly likely that Korean law will apply.
02: Whether an agreed divorce is possible or a court trial is necessary
When preparing to dissolve the marriage with a foreign spouse, you must first check if an agreement-based divorce is possible.
If the spouse cannot be contacted or does not agree to the divorce, an agreed divorce is impossible, and you must proceed through a court divorce (litigation).
03: Whether the lawsuit documents can be delivered: Service of Process Review
If the spouse is living abroad, you must assess how documents can be served locally and whether they can realistically be received.
If the address is uncertain or mail cannot be delivered, the court may allow public service of process, a special alternative procedure.
However, if you fail to provide sufficient information or evidence during this stage, the case may be delayed or even halted.
2. When is public service of process necessary for divorcing a spouse you cannot contact?
If you are considering filing a divorce lawsuit against a foreign spouse but have completely lost contact after they left the country, the first thing to check is whether there is any way to serve legal documents to them. If even their address cannot be verified, you cannot begin the process through ordinary international mail.
In such situations, the court may consider an exceptional procedure called public service of process (공시송달), which legally recognizes the documents as delivered even without actual receipt.
Public service of process is used when the other party’s whereabouts are unknown. The court posts the notice on its bulletin board (or designated platform) for a set period, and this is treated as valid service.
However, this process is not automatic or merely formal. You must provide evidence showing that you genuinely attempted to locate the other party, such as:
- Records of attempts to verify the spouse’s last known address or residence
- Proof of attempted mail delivery and returned mail
- Online search results, inquiries with administrative agencies, etc.
If the submitted materials are insufficient or lack credibility, the request for public service of process can be denied, and the case may be delayed or suspended.
Therefore, if public service of process is necessary, it is crucial to work with an international divorce attorney from the beginning to ensure proper preparation and avoid setbacks.
3. Four reasons expert assistance is essential in foreign spouse divorce cases
A divorce lawsuit involving a foreign spouse is not a simple process.
As mentioned several times, you must first confirm:
- Whether a Korean court has jurisdiction over the case,
- Which country’s law will apply,
- Whether it is possible to serve legal documents to the other party.
Only after these conditions are met can the lawsuit be formally filed. Because there are many elements to review even before starting, the assistance of an international divorce attorney is essential from the beginning.
Here’s why expert support is crucial in a foreign spouse divorce lawsuit:
① Jurisdiction, applicable law, and service requirements determine whether the lawsuit is even possible
You must first verify whether the Korean court can handle the case, whether Korean law can be applied, and whether the complaint can be delivered to the spouse. Without meeting these requirements, the procedure cannot move forward.
② Public service of process is one of the most exceptional procedures, and evidence is key
Simple statements are not enough. You must clearly prove actual attempts to confirm the spouse’s address and document the steps taken. If the evidence is insufficient or too superficial, the court may refuse to recognize the inability to serve, causing the entire case to halt.
③ Each stage requires specific documents prepared in a precise, standardized format
If you make mistakes in preparing the public service request, organizing supporting documents, or submitting materials in the proper order, the documents may be rejected or the case may be interrupted. Attempting this without practical experience is risky.
④ Beyond ending the relationship, the lawsuit must also address property division, child custody, and alimony
If the spouse is overseas, strategic planning is needed to decide how to include each claim in the lawsuit. This is another area that is extremely difficult for an individual without specialized experience to manage.
4. In a foreign spouse divorce lawsuit, every step of the procedure shapes the outcome
As emphasized repeatedly, international divorce is decided by procedure, not emotion.
In particular, when dealing with a foreign spouse with whom contact has been completely lost, the case can only proceed if the following are confirmed in advance:
- Whether the Korean court has jurisdiction,
- Which country’s law applies,
- Whether public service of process is legally possible.
If even one of these requirements is not met, the lawsuit may become invalid or be suspended altogether.
An international divorce attorney provides strategic support from the initial preparation to the final steps, and—together with immigration specialists—can also review the foreign spouse’s residence status after the divorce case.
Even if the situation arises from marital conflict, a foreign spouse divorce lawsuit must be approached cautiously and systematically, step by step.
If you want to proceed without missing any procedural requirements, the safest approach is to seek the assistance of an international divorce specialist from the very beginning.
