If the person subjected to execution fails to perform the obligations specified in the legal document according to the execution notice, the people's court has the right to inquire the relevant units about the person subjected to execution's deposits, bonds, stocks, fund units and other property. The people's court shall have the power to distrain, freeze, transfer and change the property of the person subjected to execution according to different circumstances.

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. In the practice of execution, withholding and withdrawing the income of the person applying for execution is an execution measure frequently used by the people's court. Detention and withdrawal are two closely related enforcement measures. Detention is a temporary measure, which is to temporarily withhold the income of the person applying for enforcement, stay in the original unit, and prohibit its use and transfer, so as to urge him to perform his obligations within a limited period of time. If it still fails to perform beyond the time limit, the income can be withdrawn and delivered to the applicant for execution.
