When a writ of attachment is issued against the property of the defendant, the defendant may at any time traverse the plaintiff's affidavit upon which the attachment was obtained, stating that the affidavit is untrue or legally insufficient. Upon filing of the traverse, the court shall issue a show cause order to the plaintiff requiring him to appear at a specified time, which shall not be more than ten days from the filing of the traverse, to prove the grounds for the issuance of the attachment. If the plaintiff shall fail to carry the burden of proof, the order authorizing the attachment shall be revoked.
