A pledge, if productive, i.e. (a usufructory mortgage), shall never be lost to the debtor (nádhissopakárassídet), nor shall any interest on the debt be charged; but if unproductive (i.e., hypothecation), it may be lost, and interest on the debt shall accumulate. The pledgee who does not re-convey the pledge when the debtor is ready for it shall be fined 12 panas.
