How do criminal lawyers apply for bail pending trial for criminal suspects in the investigation stage?

Lawyers should pay attention to the following points when applying for bail for criminal suspects: guarantees should be provided by close relatives or friends of criminal suspects, not by lawyers or law firms. Although lawyers can provide legal services for criminal suspects in the investigation stage and apply to the relevant authorities for bail pending trial, they mainly explain the reasons, necessity and urgency of bail pending trial, which is the basis for the case-handling organs to approve bail pending trial; However, things such as providing guarantees are not the legal scope of work of lawyers, and lawyers can only be entrusted to participate in litigation, which does not guarantee that criminal suspects will not be socially dangerous or participate in litigation in time. So lawyers should not provide guarantees for criminal suspects. However, when applying for bail pending trial, lawyers must clearly write down the guarantor's name, contact telephone number, residence and relationship with the criminal suspect, so that the investigation organ can contact and handle relevant procedures.
