If the answer of the garnishee be not excepted to, or denied within three (3) days after its filing, unless the court, or judge in vacation, for good cause shown, gives longer time, it shall be taken to be true and sufficient, and if in such case any indebtedness or liability is admitted, judgment shall be rendered accordingly, and the garnishee shall be allowed a reasonable sum out of the funds or property confessed in his hands for his trouble and expense in answering. If all liability is denied, and the denial is uncontroverted, the garnishee shall be discharged at the cost of the judgment creditor. In contested cases the costs shall be adjudged as in ordinary cases between judgment creditor and judgment debtor.
