A seller recently received $40,000 for a house worth $100,000. He would have 1 year to claim:

The correct answer is related to the concept of “Lesion Beyond Moiety.” In the context of real estate transactions in Louisiana, lesion beyond moiety refers to a situation where a seller sells property for significantly less than its fair market value, which in Louisiana Law allows the seller to have a right to seek recourse.

In this instance, the seller sold a house worth $100,000 for only $40,000. This significant undervaluation provides grounds for the seller to invoke lesion beyond moiety. Under Louisiana Civil Code, when a sale price is less than half of the value of the property, the seller has the ability to reclaim the property within a year because the sale is considered to have resulted in undue advantage to the buyer at the seller's expense.

This right allows the seller a period of one year to bring an action to reclaim property sold under such conditions. Thus, the seller in this scenario has one year to claim the property back, making lesion beyond moiety the appropriate legal principle in this case.
