Claiming Self-Defense, but Facing an Assault Charge? | Criminal Risk Guide ①

Self-defense is strictly interpreted in South Korea. Even a minor push can lead to an assault charge. If deemed as "excessive force," it results in a criminal record that can jeopardize your visa and residency status. Early legal intervention is critical for foreigners.
Claiming Self-Defense, but Facing an Assault Charge? | Criminal Risk Guide ①

SugarSquare Law & Advisors’ Insight 💁

"The legal threshold for self-defense in South Korea is much higher than most people realize."

Imagine someone approaches you aggressively, and you instinctively push them away to create distance. You believe you were simply protecting yourself, but then you are informed that you are being investigated for assault.

"Wait, wasn't that self-defense?" This is a point of major confusion for many foreign residents in Korea. While the law defines self-defense as an act to prevent an "unjust infringement," the courts interpret this very narrowly. Without a precise legal strategy, what you intended as protection can leave a permanent mark on your criminal record.

Key Takeaways: Self-Defense in South Korea

  • Strict Legal Recognition: Subjective fear or the feeling that "they were about to hit me" is rarely enough to justify physical contact.

  • The Risk of Excessive Force: If your reaction is deemed disproportionate, you will likely be charged with assault or bodily injury.

  • Impact on Residency: Even a minor fine constitutes a criminal record, which can lead to the denial of visa extensions or permanent residency.

  • Evidence is Everything: Outcomes are often determined in the early stages through consistent statements and objective evidence like CCTV.


1. How Does the Law Define Self-Defense?

Under Article 21 of the Korean Criminal Act, self-defense must be an act intended to prevent a "present, unjust infringement." While the definition seems straightforward, the court applies three rigorous criteria:

  • Was the threat real and immediate?

  • Was the act performed solely for defense?

  • Was the degree of defense reasonable and proportionate?

The most contentious issue is "proportionality." If you push someone because they raised their hand or stepped into your personal space during an argument, the court often classifies this as a preemptive attack rather than a defense. Conversely, if you retaliate more forcefully than the initial attacker, it is ruled as excessive force. In Korea, the law prioritizes objective urgency over your subjective feelings of threat.


2. What Are the Consequences of "Excessive Defense"?

If self-defense is not recognized, you may face charges of assault. In Korea, assault can be established even without physical injury; simply applying physical force—such as pushing or grabbing someone’s collar—is sufficient. If the other party submits a medical certificate for injuries, the legal stakes rise significantly.

For first-time offenders, cases often end in a fine, but this is still a criminal conviction. This record can have a ripple effect on:

  • Employment at public or international institutions

  • Professional licensing and certifications

  • Future visa applications for other countries

  • Maintenance of your stay in South Korea

For foreigners, even a criminal fine may trigger an immigration review. This mandatory review by the Immigration Office can result in deportation orders or the denial of future visa changes.


3. Early Intervention: The Deciding Factor

In self-defense cases, how the facts are organized at the beginning is everything. Investigators reach a conclusion by analyzing several key factors:

  • CCTV and dashcam footage

  • Witness testimonies

  • Police reports filed immediately after the incident

  • The severity of injuries on both sides

  • Consistency of the initial statement

During questioning, saying "I thought they were going to hit me" may be misinterpreted as an admission of a preemptive act. However, demonstrating that an attack had already commenced can shift the legal evaluation toward legitimate defense. Self-defense is not a matter of emotion; it is about meeting specific legal requirements.


4. Essential Tips to Remember During a Conflict

Even if the incident seemed minor, even if it felt like a "mutual scuffle," or even if everyone was under the influence—staying cautious until the case is officially resolved is vital.

In Korea, the safest response is to disengage and document rather than physically react. If you sense a conflict brewing:

  • Call 112 immediately.

  • Leave the area to de-escalate and organize your thoughts.

  • Secure nearby CCTV footage or record the situation if possible.

  • Avoid further confrontation at all costs.

Crucially: Do not sign any settlements or official documents from the police or immigration authorities without legal counsel. Always consult with experts who understand the nuances of Korean law.

FAQ |

Q: Can it be self-defense if I wasn't hit first?

A: It is difficult to prove self-defense during mere verbal arguments. A physical infringement must be objectively imminent or ongoing for the law to apply.

Q: If I only pay a fine, does it mean I don’t have a criminal record?

A: No.  A fine constitutes a criminal conviction and will remain on your record. For foreigners, this record is a major negative factor during visa and residency reviews.
