Referral and File Review

The file referred by the police is assigned to a prosecutor of the Public Prosecution Office (formerly the Prosecutors' Office), who reviews whether the charges are proven, the legal reasoning and the lawfulness of the evidence. Serious crimes are investigated and referred by the Serious Crimes Investigation Agency.

Next: Request for Supplementary Investigation

Explanation

A prosecutor (part of the Public Prosecution Office from October 2026 (2026.10)) receives the case sent by the police and reads the file. The prosecutor examines whether the evidence is sufficient and whether the law was applied correctly. The result of this review decides whether there will be a supplementary investigation and the direction of the disposition.

Time required
Check the timing of the disposition with the prosecutor's office in charge. If there is a supplementary investigation, that period is added (a police supplementary investigation is in principle 1 month, extendable within 1 month)
Cost
The law does not set any separate fee for being questioned at the Public Prosecution Office stage. If a summary order becomes final, you must pay the fine, and hiring a defense lawyer costs a retainer fee

Procedure guide

Read from start to finish in order. Red text marks deadlines set by law.

  1. 1

    The file sent by the police (referral) is assigned to a prosecutor of the Public Prosecution Office (formerly the Prosecutors' Office), who reviews whether the charges are proven, whether the law is correctly applied and whether the evidence is lawful. Right after the referral, find out which prosecutor's office is in charge and submit settlement and remorse materials and a written opinion. These materials should be submitted before the prosecutor makes a disposition.

  2. 2

    If the evidence is insufficient, the prosecutor asks the police for a supplementary investigation (investigating the missing parts further) (Criminal Procedure Act §197-2), and the police investigate further and send the results. In this process the suspect may be questioned again, so it is good to review the statements made earlier.

    Current step
  3. 3

    From October 2026 (2026.10), the prosecutor does not interrogate the suspect directly. Instead, if needed, the prosecutor confirms the facts by hearing the opinions of the suspect and persons concerned or receiving written opinions (Criminal Procedure Act §245-13). A defense lawyer can be present when the suspect's opinion is heard, and statements made in this process are not used as evidence at trial. Even so, they are taken into account in deciding the disposition, so organize what you want to say in advance.

  4. 4

    The prosecutor decides on one of the following: formal indictment (filing an indictment), a request for a summary order (a request to try the case on the documents alone, only for a fine, minor fine or confiscation, §448), or non-indictment (§246 · §247). Non-indictment is divided into no suspicion, suspension of indictment (there is suspicion but the case is not sent to trial), no right to prosecute and so on. What you must do next and the deadlines differ depending on the disposition.

  5. 5

    If a summary order is requested, the court orders a fine, minor fine or confiscation on the documents alone, without a public trial (a trial held in the courtroom) (§448 · §449). A certified copy of the summary order is sent to the defendant by registered mail. The deadline for requesting a formal trial starts from this day, so be sure to write down the date you received the registered mail.

  6. 6

    If you find the summary order hard to accept, request a formal trial within 7 days from the day you are notified (§453). If the defendant requests it, a heavier type of punishment than in the summary order is not imposed (§457-2), but the amount of the fine may increase, and in that case the court states the reasons for sentencing in the judgment (§457-2(2)). Even a summary order for a fine stays as a criminal record once final, so decide carefully within the deadline whether to accept it.

  7. 7

    The prosecutor tells the suspect the result of the disposition (§258(2) for non-indictment; Investigation Rules §53 for other decisions). If it is non-indictment, the case is over, and you apply for the return of seized items (환부). If it is a summary order, decide within 7 days from the day you receive the certified copy whether to request a formal trial. If it is a formal indictment, you receive a copy of the indictment and the case moves on to the criminal trial procedure, where you submit a written opinion within 7 days (§266-2).

Deadlines to keep from now

  • 7 daysStep 6 Request for a Formal Trial

Preparation and checks

  • To submit materials on time, check the prosecutor's office in charge and the case number right after the referral.
  • Before the prosecutor makes a disposition, submit a settlement agreement, damage-restoration and remorse materials, and the defense lawyer's written opinion.
  • So that your statements do not conflict, go with your defense lawyer when you attend questioning in a supplementary investigation or a hearing of opinion by the prosecutor.
  • Write down the date you received the certified copy of the summary order by registered mail, since it is the basis for counting the deadline.
  • Once the deadline passes, it becomes final, so decide within 7 days whether to request a formal trial.
  • Keep the notice of disposition, and if it is a formal indictment, prepare the written opinion to be submitted within 7 days after receiving the indictment.

When you need a lawyer

You need a lawyer's help in cases like these: after referral you need to submit a settlement agreement or written opinion before the prosecutor makes a disposition, or you have received a summary order and need to decide whether to request a formal trial.

In particular, if the deadline for requesting a formal trial passes, the fine becomes final as it is. So you need to get help within the 7-day deadline.

Current position (2/7)

Step 2 · Request for Supplementary Investigation

What to do now

If the prosecutor finds the evidence lacking, the case is sent back to the police with 'investigate further'. This is called a request for supplementary investigation (asking the police to investigate further).

At this point, you may be called in and questioned again. The police must in principle finish the supplementary investigation within 1 month, and this period may be extended within 1 month.

When you are questioned again, prepare so that you do not contradict your earlier statements.

  • So that your statements do not conflict, go with your defense lawyer when you attend questioning in a supplementary investigation or a hearing of opinion by the prosecutor.

What comes next

Step 3 · Prosecutor's Confirmation of Facts

From October 2026 (2026.10), the prosecutor does not interrogate the suspect directly. Instead, if needed, the prosecutor calls you in to hear your opinion or receives a written opinion to confirm the facts.

You can be accompanied by a lawyer, and statements made here are not used as evidence at trial. Even so, they are taken into account in deciding the disposition, so organize what you will say in advance.
