Louisiana Civil Code Tit. VII, Art. 2511. Partial eviction, rights of buyer

When the buyer is evicted from only a part of the thing sold, he may obtain rescission of the sale if he would not have bought the thing without that part. If the sale is not rescinded, the buyer is entitled to a diminution of the price in the proportion that the value of the part lost bears to the value of the whole at the time of the sale.
