The moment you receive a call from the police station or a summons for prosecution investigation, your first priority must be calmness and systematic action. Initial response in criminal cases refers to a series of actions and procedures undertaken immediately after facing accusations to minimize legal disadvantages and secure a favorable position. This article summarizes the overall principles of initial response in criminal cases in Part 1 comprehensive guide. Here, we organize actual items that must be checked in checklist format, divided by stage: before, during, and after. Focused on preventing omissions and action-oriented lists, this is structured to help you verify "what you must not miss" at each stage.

Most people don't know when they'll face criminal accusations until it happens. However, the moment you receive a call saying "the police are calling," if you're unprepared, a single word can significantly alter the investigation outcome. Therefore, below is a checklist of items you should know in advance and prepare for in case of emergency.

•☐ Pre-register 3+ contact numbers for defense attorneys — Save contact information for criminal defense lawyers or specialized law firms like Roel Law Firm in advance. This allows you to receive immediate consultation in emergency situations. Finding an attorney after receiving a police summons creates time pressure.

•☐ Prepare ID, family register copy, and bank account statement copies — Police investigations frequently require identity verification and basic document submission. Pre-organizing these allows you to respond quickly without panic.

•☐ Organize case-related evidence materials (messages, receipts, contracts, etc.) in a separate folder — Prepare materials so you can find necessary documents at a glance when consulting with your attorney later. For DUI suspicion, driving records are important; for fraud accusations, transaction records are critical.

•☐ Study basic concepts of police and prosecution procedures at least once — Understanding the meaning of terms frequently used in criminal procedures such as "summons," "suspect," "settlement," and "leniency" in advance creates psychological stability during investigation.

•☐ Prepare a statement to pre-notify your workplace, school, and acquaintances — Criminal cases spread quickly once publicized. If necessary, explain the situation in advance only to trustworthy people, and develop a public notification strategy through consultation with your attorney.

Key Point: Pre-registering attorney contact information and organizing basic evidence before police contact determines the success or failure of initial response.

When the police call saying "Please come for investigation at 2 PM on XX date," the most important things are the promptness of hiring a defense attorney and organizing basic case information. Since this timeframe is extremely tight, proceed with the following items sequentially in checklist form.

•☐ Immediately call or text a criminal defense attorney and confirm initial consultation availability — Completing the first consultation with your attorney within 24 hours of receiving a summons is ideal. In the case of Roel Law Firm (Seocho-gu, Seoul), dedicated criminal attorneys are on standby, so you can request emergency consultation.

•☐ Organize basic case information (accusation contents, case circumstances, related parties' names) one sentence each — You must clearly explain "what happened" when consulting with your attorney. For DUI suspicion, organize the date, time, and location; for fraud accusations, organize the transaction history with the victim chronologically.

•☐ Register the investigation location, date, and time in your smartphone calendar and share with your attorney — You must meet with your attorney right before the investigation to receive final advice. Make the schedule clear and notify your attorney in advance so they can attend. The attorney's role is to protect the suspect's rights during the investigation.

•☐ Save all related evidence materials (messages, call records, receipts, contracts, photos) as screenshots or files — The original device may be seized by police, so pre-backing up is essential. Your attorney will also need these materials during consultation.

•☐ Inform only your family, spouse, or one trustworthy person about the situation, keeping it confidential from others — Criminal cases can have adverse effects on later settlements and leniency if publicized at the early stage. If necessary, receive your attorney's advice before deciding on notification timing and content.

•☐ Create a list of items to bring on investigation day (ID, bank account statement, certificate of personal seal impression, attorney authorization form) and do final confirmation the night before — During police investigations, you may be asked to submit documents necessary for creating criminal complaint forms along with identity verification.

Key Point: Completing initial consultation with a criminal defense attorney within 24 hours of police contact and organizing evidence and schedule determines the investigation outcome.

The moment you enter the police investigation room, you are no longer a "civilian." You become a suspect, and all your answers to police questions are recorded in the investigation record. If your attorney is present at this stage, follow the attorney's instructions and check the following items in real time.

•☐ Listen to your attorney's advice first and never answer without consultation — Answering police questions spontaneously makes it difficult to retract later and becomes recorded evidence for use in court. If your attorney recommends exercising "the right to remain silent," clearly state "I will receive my attorney's advice."

•☐ After the investigation record is completed, thoroughly read the entire content once with your attorney before signing, and verify there are no errors, omissions, or distortions — The investigation record is an official legal document, so you must reconfirm the contents before signing. Request immediate corrections from police for any incorrect parts.

•☐ If asked to undergo physical examination (breathalyzer, DNA collection, etc.) during investigation, first confirm your attorney's consent — You can refuse unreasonable examination methods or clearly illegal procedures. Since your attorney is present, immediately seek their advice.

•☐ After investigation concludes, have a separate 30+ minute consultation with your attorney to review future procedures, settlement strategy, and anticipated punishment — The investigation ending doesn't mean the case is over. Review with your attorney whether prosecution is likely, the possibility of release without detention, and future settlement strategy.

Key Point: During police investigation, always prioritize your attorney's advice, and recheck the entire investigation record contents before signing, minimizing legal disadvantages.

Do not be relieved once police investigation ends. Police will transfer investigation results to prosecution, and most criminal cases undergo stricter reinvestigation at the prosecution stage. Therefore, you must check the following within 3-7 days after police investigation.

•☐ Request "police investigation record copy" or "investigation records" together with your attorney and understand in advance how police recorded it — By checking the police investigation record before prosecution investigation, you can prepare consistent answers for the prosecution. Roel Law Firm's criminal defense team establishes legal strategy at this stage.

•☐ Review together with your attorney "victim settlement" or "settlement amount size" and other highly preferred methods at the prosecution stage, and determine if settlement is possible — If settlement wasn't reached at the police stage, attempting settlement within 2 weeks after prosecution transfer is highly favorable for punishment reduction.

Key Point: During the maximum one-week period after police investigation and before prosecution transfer, you must review the police investigation record with your attorney and revise settlement strategy to be advantageous at the prosecution stage.

When you receive notice to "appear at the prosecution office," more cautious and systematic preparation is needed than police investigation. Prosecution has the authority to decide "whether to indict," meaning whether to forward to court trial or not. Check the following items.

•☐ Pre-review "police investigation record" + "anticipated prosecution questions" list with your attorney and prepare "consistent answer script" — Prosecution investigation is deeper and examines legal grounds more rigorously than police. Together with your attorney, practice how to deliver your position as favorably as possible without giving answers different from police.

•☐ If you've pre-prepared "victim settlement agreement" or "settlement payment proof," organize files, copies, and receipts to present during prosecution investigation — Evidence that settlement has been reached has the greatest impact on prosecution's "punishment recommendation" or "prosecution deferral" decision.

•☐ Have 30+ minute final consultation with your attorney 1-2 days before prosecution investigation to organize forbidden expressions, trap questions to avoid, and 3 key points to emphasize first — Prosecution often asks "Is this correct?" while distorting the police record contents. Your attorney's advance guidance is very important.

Key Point: Prosecution investigation is more critical than police investigation, and thoroughly reviewing police records with your attorney and preparing settlement evidence determines whether prosecution will proceed.

After prosecution investigation concludes, you'll receive "indictment" or "non-indictment" decision notice 2-4 weeks later. This stage is the final crossroad of the criminal case. If you receive a non-indictment decision, the case ends, but if indicted, it proceeds to court trial.

•☐ Upon receiving indictment notice, immediately contact your attorney and reserve a second strategy meeting to discuss "appeal/re-appeal" or "court trial preparation" — Don't despair if indicted. Specialized law firms like Roel Law Firm in Seocho-gu, Seoul, led by lead attorneys (Lee Tae-ho, Choi Chang-moo, Jang Young-don, Kwon Sang-jin, Kim Hyun-woo) deploy even stronger strategies at the court trial stage after prosecution indictment. If you receive a non-indictment decision, review the reasons with your attorney and preserve evidence materials to avoid reinvestigation on the same accusation.

Key Point: Prosecution indictment or non-indictment decision is the final crossroad of the criminal case, and if indicted, immediately establish court trial preparation strategy with your attorney.

Q1. What if police want to conduct investigation without an attorney present?

A: Never proceed with investigation without your attorney present. Suspects have the fundamental human right of "right to select attorney." Even if police say "attorneys obstruct investigations," this is an unreasonable demand that violates your legal rights. If this situation occurs, immediately contact your attorney to demand their attendance or request postponement. Roel Law Firm's criminal defense team immediately points out such improper investigation procedures and protects suspect rights.

Q2. What if police pressure you saying "if you don't settle, we'll prosecute strictly"?

A: This is clear improper pressure. Immediately report to your attorney or the police department's human rights protection officer. Your statements and settlement decision are completely separate issues, and police connecting them to apply pressure is a human rights violation. If your attorney is present, they can request that this situation be recorded in the investigation record.

Q3. If investigated for DUI, can you refuse breathalyzer or blood tests?

A: DUI prosecution relies significantly on objective test results (breathalyzer value, blood alcohol content). Refusing the test itself can result in additional prosecution for "refusal of testing." Therefore, rather than refusing the test itself, the strategy is to verify with your attorney whether the test method is appropriate (e.g., whether the measurement device is accurate, whether measurement timing is correct). If you dispute test results, you can request separate retesting during court trial.

Q4. If investigated for fraud, must you submit all messages, call records, and transaction receipts with the transaction counterparty?

A: Submit evidence materials only with your attorney's consent. Even if police say "you must provide all evidence to cooperate with the investigation," you have no obligation to voluntarily submit evidence unfavorable to you. Your attorney will review evidence materials and determine "whether submission is advantageous." If police attempt to forcibly secure evidence through search and seizure, your attorney can object to the search warrant's appropriateness in court.

Whether you receive a call from the police station, a prosecution investigation summons, or notification that you've been reported for fraud, assault, or DUI — all these moments are "critical turning points that can change your life." Criminal case initial response is not simply "responding well to police investigation," but rather systematic legal strategy that penetrates all stages from pre-investigation through investigation, prosecution transfer, to court trial.

The 17 check items organized in this article are compressed into action-oriented checklists to clarify "what you must not miss" at each stage. From preparation before police contact to prosecution indictment/non-indictment decision stage, each stage has priority and time limits.

Whether DUI suspicion, fraud accusations, assault case involvement, or any criminal case, your response in the first week greatly determines future punishment levels. Particularly, the timing and strategy of attorney selection and judgment on settlement decision must occur during the "golden period (7-14 days)" from immediately after police investigation to before prosecution transfer.

Roel Law Firm in Seocho-gu, Seoul, centered on lead attorneys Lee Tae-ho, Choi Chang-moo, Jang Young-don, Kwon Sang-jin, and Kim Hyun-woo, provides stage-by-stage professional consultation and legal strategy from criminal case initial response through court trial.
