Sale – Perfection of the contract of sale
Art. 2456. Transfer of ownership. Ownership is transferred between the parties as soon as there is agreement on the thing and the price is fixed, even though the thing sold is not yet delivered nor the price paid.
Art. 2601. Additional terms in acceptance of offer to sell a movable. An expression of acceptance of an offer to sell a movable thing suffices to form a contract of sale if there is agreement on the thing and the price, even though the acceptance contains terms additional to, or different from, the terms of the offer, unless acceptance is made conditional on the offeror’s acceptance of the additional or different terms. Where the acceptance is not so conditioned, the additional or different terms are regarded as proposals for modification and must be accepted by the offeror in order to become a part of the contract. Between merchants, however, additional terms become part of the contract unless they alter the offer materially, or the offer expressly limits the acceptance to the terms of the offer, or the offeree is notified of the offeror’s objection to the additional terms within a reasonable time, in all of which cases the additional terms do not become a part of the contract. Additional terms alter the offer materially when their nature is such that it must be presumed that the offeror would not have contracted on those terms.
