Article 1534

An unpaid seller having the right of lien or having stopped the goods in transitu, may rescind the transfer of title and resume the ownership in the goods, where he expressly reserved the right to do so in case the buyer should make default, or where the buyer has been in default in the payment of the price for an unreasonable time. The seller shall not thereafter be liable to the buyer upon the contract of sale, but may recover from the buyer damages for any loss occasioned by the breach of the contract.

The transfer of title shall not be held to have been rescinded by an unpaid seller until he has manifested by notice to the buyer or by some other overt act an intention to rescind. It is not necessary that such overt act should be communicated to the buyer, but the giving or failure to give notice to the buyer of the intention to rescind shall be relevant in any issue involving the question whether the buyer had been in default for an unreasonable time before the right of rescission was asserted.
