Article 1788

The buyer may require performance by the seller of his obligations unless the buyer has resorted to a remedy which is inconsistent with this requirement.

If the things do not conform with the contract, the buyer may require delivery of substitute things only if the lack of conformity constitutes a fundamental breach of contract and a request for substitute things is made either in conjunction with notice given under Article 1758 or within a reasonable time thereafter.

If the things do not conform with the contract, the buyer may require the seller to remedy the lack of conformity by repair, unless this is unreasonable having regard to all the circumstances. A request for repair must be made either in conjunction with notice given under Article 1758 or within a reasonable time thereafter.
