Relevant laws
Criminal Procedure Act (형사소송법) Article 200-2(5) and Article 200-4 (Deadline for Requesting a Warrant After Arrest)
To detain an arrested suspect, a detention warrant must be requested within 48 hours of the arrest. If it is not requested within that time, the suspect must be released immediately. The same applies to emergency arrests (긴급체포).
Criminal Procedure Act Articles 70 and 201 (Grounds for Detention)
A person can be detained when there is good reason to suspect they committed a crime and they have no fixed residence, or there is a risk they will destroy evidence or flee. The judge also considers the seriousness of the crime, the risk of reoffending, and any risk of harm to the victim or key witnesses.
Criminal Procedure Act Article 201-2 (Request for a Detention Warrant and Examination of the Suspect)
When a detention warrant is requested for an arrested suspect, the judge must examine the suspect by the day after the request, unless there are special circumstances. Defense counsel may attend the hearing and state their opinion.
Criminal Procedure Act Articles 215 and 219 (Search and Seizure)
Judicial police officers may search and seize only items that can be considered related to the case, under a warrant issued by a judge at the prosecutor's request. The warrant must be shown to the person subject to it (Article 118), and a list of seized items must be prepared and handed over (Article 129).
Statutes are summarized. The official Korean text is available at the Korea Law Information Center (law.go.kr).

Materials to gather within 48 hours
An arrested person is held in a cell and cannot get documents or meet people on their own. In the end, the family has to gather the materials for the pre-detention hearing from outside. In a visit, defense counsel hears how the arrest happened and what was said during questioning, and tells the family what to bring and by when.
What the judge looks at is whether the person has a fixed residence, whether there is a risk of destroying evidence, and whether there is a risk of flight. So the materials are chosen to address these three points. Materials that directly rebut each ground are better than a large volume.
- Residence: resident registration record (주민등록등본), lease agreement, family members living together
- Risk of flight: certificate of employment or business registration certificate, family relationship certificate, circumstances of dependent family
- Risk of destroying evidence: list of materials already submitted, record of complying with summonses
- Compensation for harm: settlement agreement, repayment records, documents on a court deposit
- Petitions: from family, coworkers and longtime neighbors
The pre-detention hearing does not decide guilt or innocence
At the hearing, the judge calls the suspect in and asks questions directly. Even if the charge is supported to some degree, the warrant can be rejected if the grounds for detention are not established. So we write the written opinion separating the parts that dispute the charge from the parts that dispute the need for detention.
The suspect's answers at the hearing are recorded and later read during the investigation and trial. Out of a sense of injustice, people often explain the case at length and end up contradicting what they said during questioning. In a visit before the hearing, we go over what questions may come up and how far to answer.
There are still ways to challenge detention after a warrant is issued
Not only the arrested or detained suspect, but also defense counsel, the spouse, parents, grandparents, children or grandchildren, siblings, family members, people living with the suspect and the employer can petition the court for a review of the legality of arrest or detention (체포·구속적부심사). The court examines the suspect within 48 hours of receiving the petition and may order release on the condition of posting a bond (Criminal Procedure Act Article 214-2).
After indictment, you apply for bail (보석). The court must grant bail unless, for example, the crime carries a maximum penalty of more than 10 years, the person is a repeat or habitual offender, or there is a clear risk of destroying evidence or flight (Criminal Procedure Act Article 95). If further questioning is scheduled during detention, we attend that questioning too.
What to check during a search and seizure
You cannot stop a search carried out under a warrant. Physically blocking it or hiding materials creates new problems of obstruction of official duties or destruction of evidence. Instead, ask to see the warrant, check the scope of places and items, and object on the spot to any search beyond that scope so it is recorded.
A request to hand over items not listed in the warrant is a request for voluntary submission (임의제출). Items you hand over voluntarily can be seized without a warrant (Criminal Procedure Act Article 218), so decide what to hand over in consultation with your lawyer. When the search ends, get the list of seized items and check that nothing is missing from it.
- The suspect, the charge, the place to be searched and the items to be seized as stated in the warrant
- Whether permission for nighttime execution is stated (Criminal Procedure Act Article 125)
- Whether you received the list of seized items, and whether it matches what was actually taken
- Separately write down any objections you made at the scene and when you made them
Seizure of phones and computers, and digital forensics
As a rule, for data storage media, investigators must define the scope of the necessary information and take it by printing or copying it, and may seize the device itself only when that is difficult (Criminal Procedure Act Article 106(3) and Article 219). If the whole device was taken, we take part in the later selection process to make sure information unrelated to the case is not passed on as evidence.
You can ask for the return of items that no longer need to be held, even before indictment. If the investigators refuse, you can ask the court for a decision ordering return or provisional return (Criminal Procedure Act Article 218-2). If the device is essential for your work, we ask for it to be returned first after a copy has been secured.

Frequently asked questions
If the detention warrant is rejected, is the case over?
No. Rejecting a warrant only means detention was not found necessary, and the investigation continues without detention. A warrant can be requested again for the same facts (Criminal Procedure Act Article 201(5)), so prepare for later appearances and statements as carefully as at the start.
If I am detained, will I be held until the trial ends?
During the investigation, the rule is 10 days with the police and 10 days with the prosecutor, which can be extended once by up to 10 days with a judge's permission. After indictment, the court's detention period is counted separately. In the meantime, you can still seek release through a review of the legality of detention or bail.
Can I refuse a search and seizure?
You cannot refuse a search carried out under a warrant, and physically blocking it can raise obstruction of official duties. However, you have no duty to comply with a search beyond the warrant's scope or a request to hand over items not listed in it. Objections you raise at the scene can later serve as grounds for challenging the admissibility of evidence.
When can I get my seized phone back?
Once the necessary information has been copied through forensics, there is often no longer a need to keep the phone. You can then ask for return or provisional return, and if the investigators refuse, you can ask the court for a decision (Criminal Procedure Act Article 218-2).
Can I see my arrested family member right away?
Family visits are sometimes not possible right away, depending on the holding cell's hours and the state of the investigation. Defense counsel, or someone intending to become defense counsel, can meet a detained suspect (Criminal Procedure Act Article 34), so it is quicker to check the situation through a lawyer first.
