What is the legal concept of "lesion" in a sale?

The legal concept of "lesion" in Louisiana law refers to a situation where a party to a sale or contract experiences significant detriment due to the undervaluation of the item being sold. Specifically, it occurs when one party sells property for much less than its actual value, generally defined as being more than one-half of the true value of the property. In such cases, Louisiana law allows the aggrieved party to seek rescission of the sale, as they have been essentially misled or taken advantage of in the transaction.

This legal principle aims to protect parties from entering into contracts that are grossly unfair due to substantial undervaluation of the subject matter at hand. It reflects the underlying principle of equity in contractual dealings, ensuring that transactions are conducted fairly and justly.

The other choices do not encapsulate the essence of "lesion." The notion of improper transfer of ownership, excessive contractual obligations, or a partial refusal of sale does not adequately define the concept or the specific legal recourse available under Louisiana law regarding sales involving significant undervaluation.
