G.R. No. 74679 -80 January 20, 1989
ROSITA DE ASIS, petitioner, vs. THE HONORABLE INTERMEDIATE APPELLATE COURT and CLEMENTE M. SORIANO, respondents.

FACTS

Rosita De Asis purchased a parcel of land in 1969, secured a new Transfer Certificate of Title (TCT No. 146547) in her name, built a house thereon in 1970, and resided there. She paid real estate taxes from 1969 to 1974, with receipts issued in the name of the previous owner, Ernesto Aragon, as she had not immediately updated the tax declaration. In 1977, De Asis filed a sworn statement with the City Assessor, as required by law, declaring herself the owner of the land and the house, providing her address at Mendoza Street. Despite this, the City Treasurer’s records still listed Aragon as the owner. For non-payment of taxes from 1975 to 1979, the City Treasurer initiated auction proceedings. All notices of delinquency and sale were sent exclusively to Aragon at his address, not to De Asis at her known Mendoza Street address. The property was sold at auction to Clemente Soriano in 1980. Only after the sale did Soriano discover the title was in De Asis’s name and informed the Treasurer, who then attempted to send notices to Aragon care of De Asis’s old title address, which were returned unclaimed.

ISSUE

Whether the tax auction sale was valid despite the lack of proper notice to the actual owner and registered titleholder, Rosita De Asis.

RULING

The Supreme Court ruled the auction sale was null and void. The legal logic centers on the mandatory requirement of notice under tax delinquency proceedings. For such a sale to be valid, it must comply strictly with statutory requirements for notifying the delinquent taxpayer. The Court found that the City Treasurer’s office possessed sufficient information identifying De Asis as the actual owner since at least 1977, from her sworn statement and the notice of delinquency sent to her correct address in March 1980. Despite this, all critical notices of the impending sale were sent only to the previous owner, Aragon. This constituted a fatal defect, as it deprived the true property owner of the opportunity to contest the delinquency or redeem the property. The subsequent attempts to notify Aragon care of De Asis’s outdated address did not cure this fundamental flaw. The Court emphasized that the government’s failure to update its records and notify the actual owner based on information it already possessed was gross inefficiency that impaired De Asis’s substantial rights. Consequently, the entire proceeding was void. The Court reversed the appellate decision, reinstated the trial court’s judgment annulling the sale, and ordered the bid amount deposited by De Asis to be awarded to Soriano.
