The date garnishee's answer is received by the court clerk shall be noted on the docket book in the proper manner, whether or not the answer discloses any property subject to garnishment. If the garnishee fails to appear or answer, a conditional judgment may be entered against the garnishee for the plaintiff's debt, upon which a notice shall issue to the garnishee returnable at such time as the court may require, to show cause why judgment final should not be rendered against the garnishee. On failure of the garnishee to appear and show cause, the conditional judgment shall be made final, and execution awarded for the plaintiff's entire debt and costs.
