[Direct answer]In the Beijing area, the earlier the better. Generally, the period from after being criminally detained to before the procuratorate concludes the review of the arrest is considered the golden period. In general criminal cases, the maximum detention period is 30 days. After the investigative organ submits the application for approval of arrest, the procuratorate has a period of seven days to review the arrest. Together, the maximum period is 37 days, which is known in the industry as the "golden 37 days". During this period, the investigative organ has not yet reached a fixed conclusion, and evidence is still being collected. It is the best time for lawyers to meet with clients, verify the case facts, and submit opinions on bail or refusal to approve the arrest. If the arrest has already been approved, it is still possible to apply for a review of the necessity of detention in accordance with Article 95 of the Criminal Procedure Law of the People's Republic of China (amended in 2018), but the difficulty will obviously increase. Therefore, no matter which stage the case is in, family members should hire lawyers to get involved as soon as possible and seize every available opportunity to fight for the best possible outcome.

I. Problem Background and Typical Scenarios

After a family member is detained criminally, the most pressing concern for the family is often whether they can "get the person out" as soon as possible. However, the timeline of criminal cases is not intuitive for ordinary families: the number of days of detention, when to report the arrest, and what can be done before the approval of the arrest all require professional judgment. In practice, some families wait and see in the early stages of detention and miss the best opportunity to submit a bail application to the investigative organ; others wait until the decision on the approval of the arrest is made before urgently seeking a lawyer, at which point it becomes much more difficult to apply for a change in coercive measures. When handling such cases in the Beijing area, the judgment of the investigative organ on the facts of the case, the roles involved, and the social danger will gradually solidify as the investigation progresses, and it will become increasingly difficult to change it later, so the value of the time window is extremely high.

II. Key points of dispute

Firstly, how to calculate the duration of detention, extension of detention, application for review of arrest, and the period for review of arrest. Secondly, the differences in the subjects, methods, and effects of applying for bail at different stages. Thirdly, the best time to submit opinions against approval of arrest before approval of arrest. Fourthly, the applicable conditions and difficulties of reviewing the necessity of detention after approval of arrest. Fifthly, the impact of the progress of evidence collection, compensation and understanding, and plea bargaining on the choice of time.

III. Professional analysis by Henglue Lawyers

Henglue Law Firm once represented a case of operating a gambling casino and seeking bail pending trial. The client, W*, was involved in live-streaming on an overseas online gambling platform as a chat host. The live-streaming interface was embedded with gambling advertisements and recharge entry points, and was identified by the investigating authorities as an accomplice and included in the illegal income. On December 20, 2025, W* was detained criminally. The client's family immediately appointed Attorney Zhu Guiying from our firm as the defense attorney during the critical period. The attorney promptly met with W*, seized key points such as W*'s low status as an accomplice, truthful confession, illness requiring continuous treatment, and being a first-time or occasional offender with low social danger, and built the argument around Article 67 of the Criminal Procedure Law of the People's Republic of China. The attorney promptly submitted a bail application to the investigating authorities and maintained active communication with them. On January 19, 2026, W* was granted bail according to law and regained freedom. The case took about one month from detention to bail, which was at a critical juncture between reporting for arrest and reviewing the arrest. Imagine if the client's family had hesitated and waited until after the approval of the arrest to apply for bail, they would not only have faced higher evidentiary standards but also endured longer detention. It can be seen that seizing the critical period and intervening as early as possible is an important factor in achieving ideal results in bail applications. This case was handled by Beijing Henglue Law Firm.Zhu GuiyingThe attorney (practice certificate number: 11101202011246828, subject to the certificate issued by the judicial administrative organ) acts as the agent.

The specific application shall be subject to the currently effective laws, regulations, and judicial rulings.

5. Henglu Law Firm's Reminder

Firstly, the best time to apply for bail is to intervene as soon as possible after detention, rather than waiting until after the approval of arrest to find a solution. Secondly, the "golden 37 days" is just a general guideline. In individual cases, the detention period may be longer due to factors such as extended detention or re-investigation, and the actual detention period should be calculated accordingly. Thirdly, the focus of work at different stages is different. In the investigation stage, the emphasis is on eliminating social dangers; in the review of arrest stage, the emphasis is on proving that the suspect does not constitute a crime or that the circumstances are minor. Fourthly, it's never too late to hire a lawyer at any time. After the approval of arrest, it's still possible to strive for a change through the review of the necessity of detention.

VI. Frequently Asked Questions

Q1: When is the best time to apply for bail pending trial?

The earlier the better after being criminally detained, especially during the window period before the investigative organ submits the application for approval of arrest. At this time, the evidence of the case has not been fixed, and the investigative organ is still evaluating it. The lawyer will meet with the client to verify the case and submit a bail application or an opinion against the approval of arrest. The chances of these being accepted are relatively higher.

Q2: What is "Golden 37 Days"?

The maximum duration of criminal detention is 30 days, plus the seven-day period for the procuratorate to review and approve the arrest, making a total of 37 days. This period is usually regarded as a critical period for fighting against the approval of arrest and obtaining bail pending trial. However, due to factors such as the extension of detention, the actual duration may be longer in individual cases.

Q3: Can bail be granted after the approval of the arrest warrant?

It's possible to strive for it. According to Article 95 of the Criminal Procedure Law of the People's Republic of China (amended in 2018), after a criminal suspect or defendant is arrested, the People's Procuratorate shall still review the necessity of detention. If it is not necessary to continue detention, it shall recommend the release of the person or the change of the compulsory measures.

Q4: Is it useful for family members to apply for bail on their own?

It's useful but the effect is limited. The parties involved and their legal representatives or close relatives have the right to apply for bail pending trial, but family members usually don't understand the case and the evidence in the case, making it difficult to argue each point around the social danger. Hiring a lawyer to meet, verify, and organize professional opinions is usually more conducive to grasping the timing and key points.

Q5: How much do I need to pay for bail pending trial?

For bail pending trial, the guarantor's guarantee or the bail bond may be adopted. The amount of the bail bond shall be determined by the deciding organ according to the nature of the case, the circumstances, the severity of the possible sentence and the economic conditions of the parties concerned, etc. The starting point is generally 1,000 yuan, and the specific amount shall be subject to the requirements of the deciding organ.
