CC 2781 - Sale and rent distinguished.
Art. 2781. Sale and rent distinguished.
A contract of sale, in which it is stipulated that the price shall be paid at a future time, but that it bears interest from the day of sale, is not a contract of rent.
On the contrary, a contract made bearing the name of a sale in which the seller does not stipulate the payment of the price, but at a capital bearing interest forever, is a contract of rent.
