La. Civ. Code art. 2532
A buyer who obtains rescission because of a redhibitory defect is bound to return the thing to the seller, for which purpose he must take care of the thing as a prudent administrator, but is not bound to deliver it back until all his claims, or judgments, arising from the defect are satisfied.
If the redhibitory defect has caused the destruction of the thing the loss is borne by the seller, and the buyer may bring his action even after the destruction has occurred.
If the thing is destroyed by a fortuitous event before the buyer gives the seller notice of the existence of a redhibitory defect that would have given rise to a rescission of the sale, the loss is borne by the buyer.
After such notice is given, the loss is borne by the seller, except to the extent the buyer has insured that loss. A seller who returns the price, or a part thereof, is subrogated to the buyer's right against third persons who may be liable for the destruction of the thing.
