Annulment of Property Sale Due to Fraudulent Undervaluation

A litigant sought to annul a property sale claiming the contract was void because the property was sold at a price significantly below its market value, alleging an act of fraud that prejudiced their rights, but the court of first instance rejected the claim because the price reduction, while substantial, did not inherently invalidate the transfer given that the sale was made for a fixed price without any stated condition of market value equivalence. The higher court quashed this decision, reasoning that in the context of a sale between individuals without the specific protection afforded to minors or incapacitated persons, a grossly inadequate price, when proven to be the result of fraud intended to cause prejudice, constitutes a sufficient ground for annulment because it vitiates the consent of the prejudiced party.
