Failure to Provide Pre-Sale Information Voids Land Sale Contract

A contract for the sale of land, stipulated as being "made and concluded" on a specific date, was challenged on the basis that the required pre-sale information notice, mandated by law, had not been provided to the purchaser prior to that signing, rendering the agreement null and void. The court found that the formal contractual commitment, evidenced by the parties having signed the document on the stated date, constituted the definitive sales agreement; therefore, if the preparatory administrative information disclosure obligation was not fulfilled before that moment of commitment, the requisite legal condition for the validity of the sale was absent, leading to the annulment of the decision that had upheld the contract's validity.
