If a writ of attachment is issued, the court may issue an order directing the defendant to transfer to the levying officer possession of property or documentary evidence of title to property sought to be attached. The order shall be personally served on the defendant and contain a notice that failure to comply with the order may subject the defendant to arrest and punishment for contempt of court. The order shall be served at the time of levy or, in the case of documentary evidence of title, may be served after levy on the property or debt. The order is not issued in lieu of a writ, but in addition thereto. (CCP 482.080) The levying officer must have a writ in his possession before taking custody of the property.
