Explanation of Article 255
This article addresses the statement of "proof of fulfillment," which is: proving that the debtor has fulfilled their obligation. The article stipulates that proof of fulfillment can be established by "all means of proof," meaning that fulfillment can be proven by any of the legally prescribed methods of proof, such as writing, testimony, presumptions, acknowledgment, oath, and the like.
It is worth noting that proof of fulfillment must be "correct," meaning that there should be no doubt or hesitation in its indication of fulfillment. For example, fulfillment cannot be proven by the testimony of a single person, a weak presumption, or an unclear acknowledgment.
This article is considered one of the most important articles related to proving fulfillment, as it clarifies how to prove fulfillment and enumerates its methods.
