For a foreigner, an argument that turns physical can quickly become a criminal matter in Korea. What surprises many people is that the single factor most likely to decide the outcome is not the police report or the evidence, but whether you reach a settlement (합의, hapui) with the other person.
Simple assault is not prosecutable against the victim's wishes
Under the Criminal Act (형법, Hyeongbeop), simple assault (폭행, pokhaeng) is classified as a "반의사불벌죄" (banuisabulbeoljoe), meaning an offense that cannot be prosecuted if the victim expresses a wish not to be punished. In practice this means that if you settle with the victim and they withdraw their complaint, the prosecutor must drop the case. This is why settlement is so powerful: it does not merely soften the sentence, it can stop the prosecution entirely. For a foreigner worried about a criminal record affecting future visas, that distinction is enormous.
Injury is treated more seriously
The picture changes if the contact caused a physical injury. Injury (상해, sanghae) is a heavier charge and is not a banuisabulbeoljoe. Here, a settlement does not force the prosecutor to drop the case. It remains very important, because it is the strongest mitigating factor and often leads to a suspended indictment (기소유예, gisoyuye) or a lighter sentence, but the prosecutor retains discretion to proceed. The difference between a bruise classified as assault and one documented as injury can therefore change your entire exposure, which is why a medical certificate (진단서, jindanseo) the other side obtains matters so much.
Why timing matters
Settlement is most effective when it happens early, before charges are finalized.
- If you settle and the victim withdraws the complaint before the prosecutor decides, a simple assault case is dismissed outright.
- If you settle after indictment, the court still weighs it heavily in sentencing, but the case continues.
- If you wait until after a conviction, settlement has far less effect.
Because the early window is so valuable, every day counts once an incident is reported.
Common mistakes foreigners make
Two errors recur. The first is contacting the victim directly to apologize, which can be misread as pressure or even a separate offense. The second is signing a settlement document you do not fully understand, which may waive rights or admit facts you did not intend. A settlement agreement (합의서, hapuiseo) should be precise about exactly what it covers and what the victim is agreeing to.
Get advice before you act
These cases move fast, and the right step in the first days often decides everything. A licensed Korean attorney, Sangbin Min of Daejin Law Firm, handles assault and injury matters for foreign residents and can negotiate the settlement on your behalf, so you never have to approach the other party directly. If you have been accused, a short consultation early on is the most useful move you can make.
