Can the court transfer the money from the frozen account without his signature?
 If the person subjected to execution fails to perform the judgment and order of the court, the court may forcibly allocate his bank deposit according to law. The transfer of bank deposits is a power conferred by law on the people's court and may be enforced without the consent of the depositor. Article 242 of the Civil Procedure Law If the person subjected to execution fails to perform the obligations specified in the legal document in accordance with 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. The property inquired, distrained, frozen, allocated and liquidated by the people's court shall not exceed the scope of the obligations that the person subjected to execution should perform. When the people's court decides to distrain, freeze, allocate or change the value of property, it shall make a ruling and issue a notice of assistance in execution, which must be handled by the relevant units. This is the relevant law about your problem.
