Legal basis: Article 243rd of the Civil Procedure Law stipulates that the people's court has the right to detain and withdraw the income of the person subjected to execution according to the notice of execution if he fails to perform the obligations specified in the legal documents. However, the necessary living expenses of the person subjected to execution and his dependents shall be retained. When withholding or withdrawing income, the people's court shall make a ruling and issue a notice of assistance in execution, which must be handled by the unit to which the person subjected to execution belongs, banks, credit cooperatives and other units with savings business.
