Sex crime cases in Korea: the process for foreign nationals

This guide sets out how a sex crime case actually moves through the Korean system, from the first complaint to the orders that can follow a conviction, and what the outcome tends to turn on. It is written for foreign nationals who are in one of these cases now, on either side of it. Where a specific question has its own answer, it is linked rather than repeated.

1. How the case moves, stage by stage

The complaint and the first interview

Most cases begin with a complaint made at a police station. The person complained against is usually contacted some weeks later and asked to attend for questioning. That first interview is not a formality and it is not a chance to explain things informally. What is said there is recorded, it forms the spine of the file that the prosecutor later reads, and it is very difficult to walk back.

Two practical points matter more than people expect. An interpreter is available and should be used even by someone with reasonable Korean, because the vocabulary in these interviews is technical. And a lawyer can attend from the first interview, before any charge exists.

From police to prosecutor

When the police finish, the file goes to the prosecutor with the police view of it attached. The investigation stage is therefore where most of the case is decided, even though nothing has formally happened yet. By the time a decision to charge is made, the material the decision rests on is already fixed.

The prosecutor decision

The prosecutor can charge, decline to charge, or charge but suspend the indictment. A decision not to charge is a real outcome in these cases rather than a theoretical one, and it is the outcome most defence work aims at, because it ends the matter without a conviction and without the orders that follow one.

Trial, sentence, and what comes after the sentence

If the case is charged, the sentence is only part of what is decided. A conviction for a sexual offence can carry registration and reporting duties and a restriction on working in certain places. Those consequences often matter more to a foreign national than the sentence itself, because they run for years and they reach employment and residence.

Where a foreign national case runs differently

Three things change. The first is time: an investigation that a Korean national can simply wait out may collide with a visa expiry, a contract end date or a planned departure. The second is movement, because a person under investigation for a serious offence can find that leaving the country is restricted while the case runs. The third is consequence, because a conviction that a Korean national experiences as a sentence can, for a foreign national, also reach the right to stay.

None of that changes the criminal analysis. It changes what counts as a good outcome, and it usually means immigration has to be thought about from the first week rather than after the verdict.

2. What the outcome actually turns on

A settlement does not withdraw the case

This is the single most common misunderstanding. The provision that once made these offences prosecutable only on complaint was deleted in 2013. Since then, a settlement with the complainant does not end the case. It remains highly relevant, because it goes to sentence and to the prosecutor decision, but the state can and does proceed without the complainant.

The weight given to the complainant account

These cases frequently have no witness and no physical evidence. Korean courts can and do convict on a complainant account alone where they find it credible and consistent. That is why the defence work is rarely about denial in the abstract and almost always about the specific inconsistencies, timings and messages that bear on credibility.

Contact with the complainant

Direct contact after a complaint is the fastest way to make a manageable case unmanageable. It is read as pressure even when it is meant as an apology, and it can generate a second offence on top of the first. Contact about settlement goes through a lawyer.

Deleted messages

Deleting a conversation rarely removes it, because the other side of it still exists, and the deletion itself becomes a fact in the case. The instinct to clean up a phone has damaged more cases than the contents of the phone.

The deposit, and what it is for

Where a settlement cannot be reached, a deposit with the court is the route by which a defendant can still show that compensation was attempted. It is not a substitute for a settlement and courts do not treat it as one, but it is taken into account.

3. The provisions this rests on

Registration and the duty to submit personal information sit in the Act on Special Cases Concerning the Punishment of Sexual Crimes. The restriction on employment in certain institutions sits in the Act on the Protection of Children and Youth against Sexual Abuse. The rule that a complaint can be withdrawn only up to a point sits in the Criminal Procedure Act, and the provision that once made these offences prosecutable only on complaint was deleted from the Criminal Act.

Act on Special Cases Concerning the Punishment of Sexual Crimes, Articles 42 and 43, Act No. 21066, in force from 1 October 2025; Act on the Protection of Children and Youth against Sexual Abuse, Article 56, Act No. 21108, in force from 12 May 2026; Criminal Procedure Act, Article 232, Act No. 21241, in force from 1 July 2026; Criminal Act, Article 306 deleted by Act No. 11574, in force from 19 June 2013. Current Criminal Act: Act No. 21450, in force from 13 September 2026.

4. What the courts have actually done

Three first instance and appellate decisions in our case bank turn on how compensation is treated at sentencing. In 2024GoDan2469 and on appeal in 2024No1446 and 2024No4514, the question was what weight a deposit carries when the complainant has refused to settle. The pattern across them is consistent with what is described above: the deposit is counted, but it does not do the work that an accepted settlement does.

These are lower court decisions. They show how the question is being handled rather than settling it, and a different bench on different facts can weigh it differently.

Frequently asked questions

The complainant says they will withdraw. Is it over?

No. Withdrawal matters and it is worth having, but since the complaint requirement was removed in 2013 the prosecutor is not bound by it. Treat a withdrawal as strong mitigation, not as an ending.

Can I be convicted if it is only their word against mine?

Yes. Korean courts assess whether the account is credible and consistent rather than counting witnesses. That is why the detail of what was said when, and what the surrounding messages show, carries so much weight.

Should I apologise?

Not directly, and not by message. An apology sent straight to a complainant after a complaint is routinely read as an attempt to influence them, and it can create a fresh problem. Anything of that kind goes through a lawyer.

Will my employer or my embassy be told?

Not automatically as a matter of course, but several separate routes exist by which an employer can learn of a case, and they differ depending on the stage and the outcome. That question is answered in detail separately.

I am the complainant. Do I have to go through this alone?

No. A complainant can be represented, and representation changes what the file looks like by the time the prosecutor reads it, particularly where language is a barrier and where the evidence is digital.

Can the case end without a trial?

Yes, and that is the outcome most of the work aims at. The prosecutor can decline to charge or suspend the indictment, and both of those end the matter without a conviction.
