ON BUYING AND SELLING.

I.

Buying and selling is a named contract, of good faith, in which things are exchanged for a price through consent: so that the seller is obligated to hand over the thing, and either to transfer its ownership or to guarantee against evictio legal recovery of the item by a third party: conversely, the buyer is obligated to give the price to the seller.

II.

However, not everyone can engage in buying and selling. For although this contract can exist even between husband and wife, it is null between father and son, tutor and ward, curator and adult, and certain other persons.

III.

There is no buying and selling of things that are exempted from human commerce.

IV.

Those things which we can own or possess are for the most part rightly sold: whether they are corporeal or incorporeal, whether they are movable or immovable.
