Legal analysis: generally 6 months, the longest delay is 3 months. If the bank account frozen by the court has fulfilled its corresponding obligations, it can be unfrozen, and the plaintiff and the court can be urged to unfreeze as soon as possible, otherwise it will be unfrozen naturally when the freezing time expires.

Legal basis: Provisions of the Supreme People's Court on Auction and Sale of Property in Civil Execution by People's Courts Article 29 The time limit for people's courts to freeze bank deposits and other funds of the person subjected to execution shall not exceed six months, the time limit for sealing up or distraining movable property shall not exceed one year, and the time limit for sealing up immovable property and freezing other property rights shall not exceed two years. Except as otherwise provided by laws and judicial interpretations. If the person subjected to execution applies for an extension of the time limit, the people's court shall go through the formalities of sealing up, distraining and freezing before the expiration of the time limit for sealing up, distraining and freezing, and the extension period shall not exceed half of the time limit specified in the preceding paragraph.
