According to Article 242nd of the Civil Procedure Law:

1. If the person subjected to execution fails to perform the obligations specified in the legal documents according to the notice of execution, the people's court has the right to inquire about the deposits, bonds, stocks, fund shares and other properties of the person subjected to execution from the relevant units. The people's court has the right to seal up, freeze, transfer or change the property of the person subjected to execution according to different circumstances. The property inquired, sealed up, frozen, transferred or changed in price by the people's court shall not exceed the scope of obligations that the person subjected to execution shall perform.

2. When the people's court decides to seal up, freeze, transfer or sell off property, it shall make a written ruling and issue a notice of assistance in execution, and the relevant units must handle it.

The operating companies of Alipay and WeChat undoubtedly belong to the "related units" stipulated by law. As the custodian of the property of the person subjected to execution, the court must cooperate with the court's law enforcement actions such as inquiry, freezing and deduction when it needs to go through legal procedures for handling a case.

Alipay account belongs to the scope of "other property rights" enforced by the court, and the court has the right to seal up, freeze or deduct Alipay account under the name of the person subjected to execution. In response to the question of how to deduct the money from Alipay account, Alipay said that because its current operating system cannot directly deduct the money into the court account, it can only adopt an alternative method.

For example, the case applicant can open his own account on the Alipay platform, and Alipay will transfer the corresponding funds in the account of the executed person to the applicant's Alipay account according to the requirements of the court's notice of assistance in execution, and then the applicant will withdraw the money and collect it. After the collection is successful, the applicant formally issues a receipt to the court, and finally achieves the same effect as the general bank account deduction.
