Lesion Law and Legal Definition

Lesion refers to an injury or wound. It refers to an area of wounded tissue. In civil law, lesion refers to loss from another’s failure to perform contract. It is the injury suffered by one who did not receive the equivalent value of what was bargained for. The concept of lesion maybe detriment to one of the parties to a contract which results from an imbalance or disparity between the performances performed on two sides. The burden of proving lesion is on the party asserting it, and that party must establish it by strong and convincing proof. Speculative values are not to be considered in resolving the question of whether or not lesion exists.[Whittington v. Whittington, 229 So. 2d 193 (La.App. 2 Cir. 1969)].
