Criminal Trial Procedure in Korea : What Happens After Indictment?

by | 2026. 03. 27 | Criminal Law

Detailed guide to the criminal trial procedure in Korea, covering indictment, the first trial date, and the 7-day appeal window.

One of the first questions people ask after being charged in a criminal case is simple: what happens next? In Korea, once the prosecutor files an indictment, the case moves from the investigation stage to the trial stage. At that point, the criminal trial procedure in Korea begins, and the court starts the process of reviewing the evidence, hearing the parties’ arguments, and determining whether the defendant is guilty and, if so, what sentence should be imposed. If you are looking for a criminal lawyer in Korea, understanding this process is often the first step toward building an effective defense strategy.

Korean criminal procedure is generally structured as a three-instance system. In practical terms, the first and second instances focus heavily on factual disputes, while the final instance primarily reviews legal issues. Because of that, the first trial is often the most important stage for building the factual defense in a criminal case.

 

Investigation and Trial Are Different Stages

The investigation stage is where the police and prosecutors examine the alleged offense and collect evidence. The trial stage is different. At trial, the court evaluates the prosecution’s evidence, hears the parties’ positions, and decides whether the defendant is guilty and, if so, what sentence should be imposed. This distinction matters because defense strategy often changes significantly once a case moves from investigation to trial.

At Kang & Shin Law Firm, we regularly advise foreign clients on how criminal investigations and trial proceedings differ under Korean law.

 

First-Instance Criminal Trials in Korea Usually Turn on One Key Issue

In many first-instance criminal cases, the overall path of the trial depends on whether the defendant admits the charges or contests them. If the defendant admits the alleged facts, the evidentiary phase may be shorter and the case may conclude more quickly. If the defendant disputes part or all of the charges, the court may need to hear witnesses, review contested documentary evidence, and address additional legal and factual issues. As a result, contested cases often take longer than straightforward admission cases.

 

Step-by-Step: How a First-Instance Criminal Trial Proceeds

1. Indictment and Service of the Charging Document

Once the prosecutor files the indictment, the case is assigned to a court and the defendant is served with a copy of the charging document. From that point, the defendant and defense counsel must review the charges carefully and decide what will be admitted and what will be contested.

2. Appointment of Counsel and Review of the Record

One of the most important early steps is reviewing the prosecution’s record. The issue is not only what the prosecution alleges, but how the prosecution intends to prove it. In some cases, court-appointed counsel may be available, depending on the defendant’s circumstances and the nature of the charges.

3. The First Trial Date

Trial proceedings typically begin with the presiding judge informing the defendant of the right to remain silent and confirming the defendant’s identity. The prosecutor then states the substance of the charges, and the defense responds to the allegations. The court also organizes the issues in dispute and the evidentiary matters to be addressed.

4. Examination of Evidence and Witness Testimony

If the defendant contests the charges or objects to evidence, the case usually moves into a fuller evidentiary phase. Witnesses may include the complainant, eyewitnesses, investigators, or individuals connected to documents submitted in evidence. In practice, the defense’s role at this stage is often to test credibility, expose inconsistencies, challenge reliability, and identify gaps between testimony and objective evidence.

5. Closing Stage and the Defendant’s Final Statement

After the evidentiary stage is complete, the case moves toward conclusion. The prosecutor states the requested sentence, defense counsel presents the closing argument, and the defendant is given an opportunity to make a final statement.

6. Judgment and the Possibility of Immediate Detention

Following the conclusion of the closing arguments and final statements, the court will formally close the proceedings and schedule a date for the judgment. On this day, the presiding judge will announce the verdict, determining the defendant’s guilt or innocence. If a conviction is issued, the specific sentence will also be pronounced at this time, concluding the first-instance trial phase.

7. Appeal Deadline

If a party wishes to challenge the first-instance judgment, timing is critical. Under Korean criminal procedure, the appeal period is seven days, and the notice of appeal must be submitted to the original trial court.

 

What Matters Most in a First-Instance Criminal Trial

In practice, three issues often matter most in a first-instance criminal case. First, the defendant must decide carefully whether to admit or contest the alleged facts. Second, the defense must review the prosecution’s evidence closely and determine what should be challenged. Third, witness examination and overall courtroom strategy must be prepared thoroughly, because the first-instance trial often shapes the direction of the entire case.

 

Final Thoughts

A first-instance criminal trial in Korea is not simply a matter of appearing in court a few times. The outcome can be shaped by how the defense responds to the indictment, what evidence is contested, how witnesses are examined, and how the defense presents its position at each stage. In contested cases especially, careful preparation from the beginning can make a significant difference.
