When demand is made of the garnishee upon the execution, in any of the cases mentioned in sections 52-389, 52-390 and 52-391, within the periods therein specified, the garnishee may pay the debt, or deliver the legacy or distributive share, so attached, to the officer making the demand, to be applied on such execution; and if, at the time of such payment or delivery, the garnishee would have been required by law to make such payment or delivery to the defendant, if there had been no attachment, or would have been justified in so doing, he shall be credited for such payment or delivery to the officer, in his administration account.
