Article 1779

Except as provided in Article 1780 and 17.81, the risk passes to the buyer when he takes over the things or, if he does not do so in due time, from the time when the things are placed at his disposal and he commits a breach of contract by failing to take delivery.

However, if the buyer is bound to take over the things at a place other than a place of business of the seller or, in the absence thereof, the place where the seller is domiciled, the risk passes when delivery is due and the buyer is aware of the fact that the things are placed at his disposal at that place.

If the contract relates to things not then identified, the things are considered not to be placed at the disposal of the buyer until they are clearly identified to the contract.
