Chapter III: Things that can be sold.

Anything in commerce may be sold where particular laws have not prohibited its alienation.

The sale of someone else’s thing is void: it may give rise to damages where the buyer was unaware that the thing belonged to someone else.

If at the time of the sale the thing sold had perished in its entirety, the sale would be void. If only part of the thing has perished, it is at the option of the purchaser to abandon the sale, or to demand the part retained, having the price determined by the breakdown.
