Legal analysis: 1. The bank freezing system will automatically unfreeze after half a year. Generally, if the case is not closed, the court will "continue to freeze" the relevant documents.

After 2.6 months, the bank system will automatically unfreeze, and if there are no relevant documents, the bank will not freeze again.

3. The court will continue to freeze those documents that will definitely "not close the case". If the case is closed within 6 months, the court will go to the bank to unfreeze it with a "notice of unfreezing". According to the regulations, the parties concerned should be informed. The second freeze depends on the progress of the case, and the longest time for the banking system is 6 months.

Legal basis: Article 143 of the Criminal Procedure Law of People's Republic of China (PRC), if it is found that the seized or detained property, documents, mails, telegrams or frozen deposits, remittances, bonds, stocks, fund shares and other property are really irrelevant to the case, the seizure, seizure and freezing shall be lifted within three days and returned.
