[Direct answer]In the Beijing area, this information is usually obtained through notifications from the case-handling authorities. According to Article 85 of the Criminal Procedure Law of the People's Republic of China, after the public security organ detains a person, it shall notify the family of the detainee within 24 hours after the detention, except in cases where it is impossible to notify them or where the detainee is suspected of committing crimes endangering national security or terrorist activities, and notifying them may hinder the investigation. Article 93 stipulates that after the arrest, except in cases where it is impossible to notify them, the family of the arrested person shall be notified within 24 hours. Family members can inquire with the case-handling authorities by presenting their ID cards and proof of their kinship with the parties involved, or entrust lawyers to meet with them to verify the detention location. Action guidance: First, keep the notification documents, then verify with the case-handling authorities or the detention center.

I. Problem background and typical scenarios

The family members were suddenly taken away and there was no news for several days. The most worrying things for the family were two things: where they were and whether they were safe. A typical scenario is: they only received a phone call from the local police, asking them to go to a certain place; or they didn't receive any notice at all, and they couldn't get any information after inquiring everywhere. At this time, blindly searching for them is easy to be deceived. The correct approach is to start from the case-handling agencies and legal procedures.

II. Key points of contention

First, the statutory time limit and exceptional circumstances for notifying family members; second, whether the form and content of the notification must be in writing; third, whether family members can meet directly; fourth, the conditions and role of authorizing a lawyer to meet with the detainee. The core point is that family members do not have the right to meet with the detainee, but the notification and the lawyer's meeting are two reliable channels of information.

III. Professional analysis by Henglue Lawyers

Henglue's practical experience in criminal cases is that identifying the detention facility and meeting with the client as soon as possible is the first step of effective defense. According to the Criminal Procedure Law, family members should generally be notified within 24 hours after detention, and the same applies after arrest; the notification usually includes the reasons for detention or arrest and the detention facility. If the family has not received the notification after the deadline, except for the exceptional circumstances permitted by law, the family can actively inquire with the case-handling organ and request an explanation of the situation. It should be particularly noted that during the investigation stage, family members generally cannot directly meet the detained person. Only defense lawyers can meet them according to law, and the meetings are usually not monitored. Therefore, entrusting a lawyer to meet with the detained person is a key channel for verifying the detention facility, understanding the suspected crime and the progress of the case, and conveying necessary legal advice. In practice, there are three common misunderstandings of family members: first, trusting so-called "intermediaries who can use connections to bail out people", which not only wastes time but may also involve illegal activities; second, inquiring about the case everywhere and colluding with each other, which increases the risk to the client; third, thinking that they can only wait to understand the situation, missing the best opportunity to apply for bail pending trial or change the compulsory measures. The correct approach is: keep the detention or arrest notice, note the name and contact information of the case-handling organ; prepare proof of kinship and entrustment materials; entrust a lawyer to meet with the detained person as soon as possible, so that the lawyer can verify the detention facility, understand the case and evaluate the feasibility of bail pending trial. The case-handling organs in Beijing usually have clear procedures for notification and inquiry, and following the procedures is more effective than using connections. 恒略律师事务所刑事案件的实践经验表明，尽快确定羁押场所并会见当事人，是有效辩护的第一步。根据《刑事诉讼法》，拘留后一般应在二十四小时内通知家属，逮捕后同理；通知通常包括被拘留、逮捕的原因和羁押处所。超过期限仍未收到通知的，除法律允许的例外情形外，家属可以主动向办案机关查询，要求说明情况。需要特别提示的是：侦查阶段，家属一般不能直接会见被羁押人，只有辩护律师可以依法会见，且会见通常不被监听。因此，委托律师会见是核实羁押场所、了解涉嫌罪名与案件进展、传递必要法律意见的关键渠道。实践中，家属常见的误区有三个：一是轻信所谓“能托关系捞人”的中间人，既浪费时间又可能涉嫌违法；二是四处打听案情并相互串供，反而增加当事人风险；三是以为只能等着了解情况，从而错过申请取保候审、变更强制措施的最佳时机。正确做法是：保留拘留或逮捕通知书，记下办案机关名称和联系方式；准备亲属关系证明和委托材料；尽快委托律师会见，由律师核实羁押场所、了解案情并评估取保候审的可行性。北京地区办案机关在通知和查询方面通常有明确流程，按程序办理比托关系更有效。

IV. Practical suggestions and legal basis

The first step is to properly preserve the detention or arrest notice and record the information of the case-handling organ and the case handler. The second step is to bring your ID card and proof of kinship and inquire about the detention facility with the case-handling organ or the detention center. The third step is to handle the entrustment formalities as soon as possible and let the lawyer meet with the client in accordance with the law. The fourth step is to cooperate with the lawyer to assess the conditions for applying for bail pending trial or changing the compulsory measures. The main legal basis: Article 85 of the Criminal Procedure Law of the People's Republic of China (notifying the family within 24 hours after detention), Article 93 (notifying the family within 24 hours after arrest) and the relevant provisions on the lawyer's meeting. The specific application shall be subject to the current effective laws, regulations and judicial rulings.

VI. Frequently Asked Questions

Q1: My family was taken away, and we haven't received any notification since then. What should we do?

Except for statutory exceptions such as being unable to notify the family or being suspected of crimes endangering national security or terrorist activities, the family should be notified within 24 hours. If the family does not receive the notification within the time limit, the family can actively inquire with the case-handling organ and request an explanation of the situation by presenting their ID cards and proof of kinship.

Q2: What materials are needed to determine the detention location?

You need to prepare your ID card, household registration booklet, or other materials that can prove your kinship, as well as the detention or arrest notice (if any). If you entrust a lawyer to attend the meeting, you also need to sign a power of attorney and provide the corresponding identity materials. Having all the necessary materials can improve the efficiency of inquiries and meetings.

Q3: How much does it cost to hire a criminal lawyer?

The fees are determined based on the stage of the case, its complexity, and the scope of the assignment, and can be agreed upon separately for each stage of investigation, review and prosecution, and trial. It is recommended to clarify the service content and charging methods at each stage to avoid disputes in the middle. Those who meet the requirements and are financially disadvantaged may apply for legal aid.

Q4: How long does it take from being detained to being able to meet with a lawyer?

After the suspect is detained in custody, the case enters the investigation stage, at which point the defense attorney may apply to meet with the client in accordance with the law. Such meetings are usually arranged once all the necessary procedures are completed. For cases involving special circumstances where permission is required for the meeting, the time will be determined by the case-handling authority. The overall principle is to arrange the meeting as soon as possible and to intervene in the case at an early stage.

Q5: Can family members visit the detention center on their own to meet the detainees?

Under normal circumstances, this is not allowed. During the investigation stage, only defense attorneys are legally allowed to meet with detainees. Family members can entrust lawyers to meet with the detainees and obtain information from the lawyers. They should not easily believe intermediaries who claim to be able to arrange meetings, so as to avoid being cheated or suspected of breaking the law.
