The custody institutions involved in criminal procedure have four modes: “department
custody mode”, “centralized custody within the department mode”, “centralized custody across
departments mode”, “the combination between centralized custody across departments and the third-
party escrow mode”. The department custody mode has many circulation links, large custody risks and
many custody subjects. The centralized custody within the department mode only exists in the public
security organs, procuratorates and courts, and its scope of application is limited. The centralized
custody across departments mode establishes centralized management center across departments,
but it could not effectively take care of special properties and documents. In order to separate the case
handling department from the custody department and the case handling personnel from the custody
personnel, and to ensure the value and value appreciation of involved properties, China should adhere
to the mode of the combination between centralized custody across departments and the third-party
escrow, and set up cross-department centralized custody institutions, which are supplemented by the
joint custody of third-party escrow institutions.
