In the Philippines, property owners bear the responsibility of formally registering their ownership and declaring their property for tax purposes. This Supreme Court decision underscores that local government units can rely on official records when sending notices of tax sales. It reinforces the principle that unregistered property transfers do not bind the government, upholding the validity of tax sales when notice is properly given to the registered owner on record.

Unregistered Interests and Tax Sales: Whose Responsibility Is It to Declare Property?

The case of Spouses Hu Chuan Hai and Leoncia Lim Hu v. Spouses Renato Unico and Maria Aurora J. Unico revolves around a dispute over a property sold at a tax auction. The Unico spouses purchased a property in Fairview Park Village, Quezon City, but failed to register the sale or declare it for tax purposes. Consequently, due to their tax delinquency, the property was sold at public auction to the Hu spouses. The Unicos then filed a complaint to annul the sale, arguing they didn’t receive notice. The Supreme Court ultimately sided with the Hu spouses, reinforcing the importance of registering property and declaring it for tax purposes, as the government is entitled to rely on official records.

The core legal question addressed was whether the tax sale was valid given that the notice was sent to the registered owners (the De los Santos spouses) and not the actual occupants (the Unico spouses) who had failed to register their interest. The Court emphasized the principle of res judicata, noting that the earlier decision granting the consolidation of ownership to the Hu spouses in a land registration case should have barred the Unicos’ subsequent action to annul the tax sale. Building on this, the Court delved into the obligations of property owners concerning real property taxes. Section 6 of Presidential Decree (PD) 464, which was then in effect, mandated that property owners declare the true value of their property for tax purposes. While the Local Government Code has since superseded this provision, the underlying principle remains: property owners must ensure their ownership is properly recorded and declared.

In reaching its decision, the Supreme Court referenced the case of Talusan v. Tayag, highlighting that a decision in a land registration case precludes a subsequent action for annulment of auction sale. This demonstrates the importance of resolving property disputes in a timely manner through the proper legal channels. With regard to the tax sale, the Court noted the local treasurer can rely on the Registry of Deeds to determine the rightful taxpayer. The Court underscored the importance of official records in determining who should receive notice of a tax sale, stating:

“Thus, in identifying the real delinquent taxpayer, a local treasurer cannot rely solely on the tax declaration but must verify with the Register of Deeds who the registered owner of the particular property is.”

In this case, because the Unico spouses failed to register their ownership or declare the property in their names, the City Treasurer was justified in sending the notice to the De los Santos spouses, who remained the registered owners. The Court effectively held that the consequences of failing to register a property transfer fall on the buyer, not on the government. This ruling serves as a stern reminder that failure to comply with registration requirements can have serious repercussions, including the loss of property through a valid tax sale.

Furthermore, the decision reinforces the principle that due process in tax sales requires reasonable efforts to notify the registered owner. While actual notice to all interested parties is ideal, it is not always required. What is essential is that the government follows established procedures and relies on official records to identify and notify the appropriate parties. The Court’s ruling aligns with the broader policy goal of ensuring efficient tax collection and upholding the integrity of the Torrens system of land registration.

This case shows the practical implications of neglecting to register property transfers. The Unico spouses’ failure to comply with legal requirements ultimately led to the loss of their property. This case also clarifies the responsibilities of local government units in conducting tax sales. The treasurer is obligated to notify only the registered owner according to the Registry of Deeds, not unregistered buyers or occupants. Ultimately, this ruling encourages diligence among property buyers and streamlines the process of tax collection.
