Article 1819

A party who is bound to preserve the things in accordance with Article 1816 or 1817 may sell them by any appropriate means if there has been an unreasonable delay by the other party in taking possession of the things or in taking them back or in paying the price or the cost of preservation, provided that reasonable notice of the intention to sell has been given to the other party.

If the things are subject to rapid deterioration or their preservation would involve unreasonable expense, a party who is bound to preserve the things in accordance with Article 1816 or 1817 must take reasonable measures to sell them. To the extent possible he must give notice to the other party of his intention to sell.

A party selling the things has the right to retain out of the proceeds of sale an amount equal to the reasonable expenses of preserving the things and of selling them. He must account to the other party for the balance.
