[Direct answer]In the Beijing area, this is usually determined through detention notices and consultation with lawyers. According to the Criminal Procedure Law of the People's Republic of China (amended in 2018), after the public security organ detains a person, unless it is impossible to notify the family or the case involves crimes endangering national security or terrorist activities that may hinder the investigation, the public security organ shall notify the detainee's family within 24 hours after the detention; the detainee shall be immediately detained in a detention center and shall not be detained for more than 24 hours. After receiving the detention notice, the family can use it to understand the case-handling organ and the detention place; if they have not received it or the information is unclear, they can have their entrusted defense lawyers inquire about the situation from the case-handling organ and arrange a meeting with the detainee according to law. The notification methods and time limits for different cases shall be handled in accordance with the law, and the family may also inquire about the situation from the case-handling organ in accordance with the regulations.

1. Problem background and typical scenarios

After family members are taken away, the most urgent concern for their relatives is to find out where they are detained and what charges they are suspected of. Typical situations include: not receiving detention notices in a timely manner and suspecting that they have been taken away by case-handling authorities from other regions; incomplete information on the notice or delays in mailing it; and delayed notification due to the special nature of the case. Criminal cases in the Beijing area are handled by the corresponding case-handling authorities, and the detention facilities are relatively fixed. It is feasible to inquire about this through legal channels.

II. Key points of dispute

First, how should we understand the time limit and exceptional circumstances for notifying family members after detention? Second, what legal channels can family members use to inquire about the detainee's whereabouts if they haven't received the notice? Third, what is the role of a lawyer in the process of inquiry and visitation? Fourth, does the delay in notification or failure to notify affect the handling of the case? Fifth, can family members exchange information with the detainee, and what are the boundaries of such communication?

III. Professional analysis by Henglue Lawyers

Here's the translation of the Chinese (Simplified) sentence into English, with a detailed explanation: \nHenglue Law Firm offers four practical tips for criminal defense. First, the notice is a crucial clue: The detention notice typically specifies the case-handling authority, the suspected crime, and the detention facility. Family members should keep it safely and provide it to the lawyer as soon as possible; if it's delivered by mail, they should check for receipt. Second, lawyers can conduct more efficient inquiries: Defense lawyers appointed by the client can legally inquire about the suspected crime and related circumstances from the case-handling authority, and visit the detention center with their practice certificates, firm certificates, and power of attorney or legal aid letters to confirm the detention facility and the physical condition of the detainees. Third, attention to details: In some cases, notifying family members may hinder the investigation, which is an exception permitted by law. Family members should not inquire through unofficial channels to avoid being deceived or causing risks. Fourth, information transmission must comply with regulations: Family members' concerns and necessary living information can be conveyed by lawyers according to the law, but they must not transmit content that might affect the investigation or collude to obstruct evidence collection. Fifth, timeliness is crucial: The earlier the detention location and suspected crime are confirmed, the better it is for lawyers to arrange meetings, evaluate coercive measures, and put forward opinions, thereby gaining time for subsequent defense. Overall, family members should rely on the information provided upon detention and lawyers' legal inquiries to proceed rationally, rather than seeking help through unofficial channels.

VI. Frequently Asked Questions

Q1: How long after criminal detention will the family be notified?

According to the Criminal Procedure Law, after the public security organ detains a person, except for the circumstances where it is impossible to notify the family or where the notification might hinder the investigation of crimes involving national security or terrorist activities, the public security organ shall notify the family of the detained person within 24 hours after the detention. The specific method and time of notification shall be subject to the case-handling organ's legal announcement.

Q2: What should I do if I haven't received a detention notice?

You can actively inquire with the possible case-handling authorities in accordance with the regulations, or entrust a defense lawyer to obtain information from the case-handling authorities and arrange a meeting with them in accordance with the law. If it is indeed a situation where the law stipulates that notification may be temporarily postponed, the notification time will be correspondingly delayed. Family members should keep the communication channels open and pay attention to notifications by mail and phone.

Q3: How can a lawyer find out where the detainee is being held?

Defence lawyers, with their lawyer's practice certificates, certificates from law firms, and power of attorney or legal aid letters, can legally inquire about the suspected charges and case details from the case-handling authorities, and visit the detention centers to meet with the detained criminal suspects. Through the information provided by the case-handling authorities and the arrangements for the meetings, they can usually confirm the detention facilities.

Q4: Can family members send things to people who are detained?

It can be handled in accordance with the regulations. Family members can consult the detention center about the methods of depositing daily necessities and funds. Generally, they need to provide identity proof and abide by the management regulations of the detention center. Communication regarding case information and case content should be conducted through lawyers in accordance with the law, to avoid transmitting information that may affect the investigation.

Q5: Does notifying the family mean that the case is not serious?

Not necessarily. Notifying the family is a legal procedural requirement, and there is no necessary correlation with the severity of the case. The nature of the case needs to be judged based on the suspected crime, the evidence situation, and the handling decision of the case-handling organ. The specific information should be subject to the legal documents and the notifications from the case-handling organ.
