The vendor in good faith shall be responsible for the existence and legality of the credit at the time of the sale, unless it should have been sold as doubtful; but not for the solvency of the debtor, unless it has been so expressly stipulated or unless the insolvency was prior to the sale and of common knowledge.
Even in these cases he shall only be liable for the price received and for the expenses specified in No. 1 of article 1616.
The vendor in bad faith shall always be answerable for the payment of all expenses, and for damages. (1529)
