Legal analysis: If the case is not closed, the court will continue to freeze it according to relevant documents. After freezing for 6 months, if the relevant documents are not restricted, the bank will not continue to freeze. If the case has been closed within 6 months, the court will take the notice of unfreezing to the bank for unfreezing. If the frozen property has been auctioned or mortgaged, the effectiveness of sealing up and freezing will disappear.

Legal basis: Article 144 of the Criminal Procedure Law of People's Republic of China (PRC).

The relevant units and individuals shall cooperate. If a criminal suspect's deposits, remittances, bonds, stocks, fund shares and other properties have been frozen, they may not be frozen again.

Article 145 If the seized or detained property, documents, mails, telegrams or frozen deposits, remittances, bonds, stocks, fund shares and other properties are found to be really irrelevant to the case, the seizure, seizure and freezing shall be lifted within three days and returned.
