What Happens in the First 48 Hours After Arrest in Korea?

Key Summary

Korean law requires investigators to seek a detention warrant within 48 hours of an arrest or release the suspect. Here is what happens procedurally in that window, including the rights a foreign national has during it.

The first two days after an arrest in Korea are governed by specific procedural deadlines, not open-ended discretion. Knowing what is supposed to happen in that window, and what rights apply during it, matters most in the moment it is hardest to think clearly.

Korean police can arrest a suspect with a court-issued arrest warrant (체포영장), through an emergency arrest (긴급체포) when there is urgency and a flight or evidence-destruction risk, or in the act of an offense (flagrante delicto). Which type applies affects some procedural details, but the core timeline that follows is largely the same.

Under Articles 200-2 and 200-4 of the Criminal Procedure Act, once a person is arrested, investigators must either request a detention warrant (구속영장) from a court within 48 hours or release the person. This is not a suggestion; it is a hard deadline built into the statute. If the 48 hours pass without a request being filed, continued detention on that basis is not lawful, and release should follow.

If investigators do seek a detention warrant, the suspect appears before a judge for a warrant review hearing, generally referred to as 영장실질심사. This is where the judge decides whether continued detention is warranted, considering factors such as flight risk, risk of evidence destruction, and the severity of the alleged offense. Defense counsel can attend this hearing and argue against detention on the specific facts of the case.

From arrest onward, a suspect has the right to remain silent, the right to have a defense attorney present during questioning, and the right to have family or another person notified of the arrest. A foreign national additionally has the right to request that their consulate or embassy be notified, under Article 36 of the Vienna Convention on Consular Relations. If the suspect cannot communicate effectively in Korean, an interpreter should be provided for questioning — this is not optional and should be requested explicitly if it is not offered.

Defense counsel can be appointed before indictment by submitting a written power of attorney (변호인선임서) to the investigating agency, under Articles 30 and 32 of the Criminal Procedure Act. Once appointed, counsel can attend police questioning, review the direction of the investigation, and represent the suspect at the warrant hearing. This is also the point at which a Provisional Retainer (가선임) arranged before entering Korea becomes directly useful: if the retainer already has a case identified, the power of attorney can be filed with the relevant agency immediately rather than being arranged from scratch after arrest.

Family members are often the first point of contact when someone is arrested in Korea, especially at Incheon Airport. Our companion article, What Should Your Family Do if You Are Arrested at Incheon Airport?, covers what to do in practical terms during exactly this 48-hour period.

The type of arrest can affect how quickly things move. An arrest with a warrant (체포영장) means a judge has already reviewed the request before the arrest happens, whereas an emergency arrest (긴급체포) is made first, without a prior warrant, based on the officer's assessment of urgency, and is subject to review afterward. Practically, both still feed into the same 48-hour framework for seeking a detention warrant, but the paperwork and justification an officer must be prepared to show can differ, and a defense lawyer will look closely at whether an emergency arrest was actually justified under the circumstances, since an improperly conducted emergency arrest can itself become a point raised at the warrant hearing.

If a detention warrant is issued, detention can continue while the investigation proceeds toward a decision on indictment, subject to further review by the court. If a warrant is not sought, or is denied, release does not necessarily mean the file is closed; it means the investigation continues without the person being held in custody for the time being. Either way, the procedural stage after these first 48 hours is different from the initial arrest itself, with its own timelines and its own decisions to be made with counsel.

This is a general sequence under Korean criminal procedure, including the revised Criminal Procedure Act effective October 2, 2026. Not every case follows this exact sequence, and nothing here promises release at any stage.

• On arrival: a wanted registration (지명수배) with an arrest warrant can be flagged at passport control; a notification-only registration (지명통보) usually means being told to report to the investigating station instead.
• At the time of arrest: police must state the gist of the alleged offense, the reason for arrest, and your right to appoint a lawyer, and give you a chance to respond (CPA art. 200-5).
• Without delay, and no later than 24 hours: police must notify your lawyer or a person you designate, in writing (CPA arts. 200-6, 87; Criminal Procedure Rules art. 51); foreign nationals can ask that their embassy or consulate be informed (Vienna Convention on Consular Relations, art. 36).
• Same day: you are usually transferred to the police station handling the case, where questioning (피의자신문) is conducted, with your lawyer able to attend (CPA arts. 241, 243-2).
• Within 48 hours of arrest: unless a detention warrant (구속영장) is requested — police apply, and a prosecutor at the Public Prosecution Service (공소청) files the request with the court — you must be released (CPA art. 200-2(5)).
• Usually by the next day after the request: a judge holds the detention hearing (영장실질심사) without delay (CPA art. 201-2(1)); if you have no lawyer, the court appoints one (art. 201-2(8)).
• If detention is ordered: up to about 30 days before indictment — police up to 10 days, then the prosecutor up to 10 days, extendable once by up to 10 days with court permission (CPA arts. 202, 203, 205).

If there is a real possibility of being detained on arrival, having a lawyer already in place before you land removes the need to find one for the first time inside a 48-hour deadline. A Provisional Retainer (가선임) registers your travel details in advance and can carry through into Emergency Criminal Representation if detention actually happens. See our Pre-Entry Risk Review page.
