Transfer of Ownership Validity Against Third-Party Creditors Without Public Registration

A seller, who was also the proprietor of a property, transferred ownership to a purchaser under a private agreement, but failed to file the necessary public deed of sale with the competent authority, leading to a dispute when a creditor of the seller sought to seize the property under a prior judgment that remained valid against the seller because the transfer was not properly recorded. The court upheld the seizure, reasoning that while a private agreement transfers ownership between the contracting parties, registration with the competent authority is required to render that transfer opposable to third parties, such as creditors, ensuring that in the absence of proper publicity, the property remained legally available for execution by pre-existing claims against the former owner.
