Art. 3170. Pledgee's right to enforce payment of credit pledged; imputation of proceeds.
If the credit which has been given in pledge becomes due before it is redeemed by the person pawning it, the creditor, by virtue of the transfer which has been made to him, shall be justified in receiving the amount, and in taking measures to recover it. When received, he must apply it to the payment of the debt due to himself, and restore the surplus, should there be any, to the person from whom he held it in pledge.
