Tax Delinquency and Public Auction: When a Tax Sale of Land Is Invalid

The Supreme Court has long protected property owners from defective tax sales. In Requiron v. Sinaban (G.R. No. 138280, March 10, 2003), the Court nullified a tax delinquency auction sale because the supposed buyer failed to prove that the sale even took place. The case is a reminder that a tax sale is a strict proceeding — and the buyer, not the government, carries the burden of proving its regularity.

The Dispute Over Lot No. 915

Lot No. 915 in Sagay, Negros Occidental was originally co-owned by several members of the Javello family. Over time, the heirs sold their shares to Teofilo Asuelo through a series of deeds. The other heirs disputed these sales, claiming the documents were forged or executed by an illiterate seller, and filed a case to recover the property.

While that case was pending, the property's real property taxes went unpaid. The municipal treasurer scheduled a public auction for December 14, 1973. Before the auction, one of the defendants made a partial payment of the tax delinquency to the provincial treasurer, who sent a radio message suspending the sale.

Despite this, Leon Requiron claimed he paid the delinquent taxes on December 12, 1973 — two days before the scheduled auction — and that he was the winning bidder when no one else appeared on auction day. He later obtained a document called a "Certificate of Repurchase of Real Property After Sale" and, eventually, a title over the property.

The Issue

The sole issue before the Supreme Court was whether the public auction sale of Lot No. 915 was valid.

The Ruling: No Proof, No Valid Sale

The Supreme Court denied Requiron's petition and affirmed the Court of Appeals' decision nullifying the auction sale. The Court held that Requiron failed to prove the regularity of the proceedings leading to the sale.

The Court stressed that the presumption of regularity in the performance of official duties does not apply to administrative proceedings that result in the deprivation of a citizen's property. The burden was on Requiron to prove that the auction was validly conducted.

Under Commonwealth Act No. 470, the "Assessment Law" applicable at the time, a valid tax sale requires certain documents: a Report of Sale made within five days after the sale, a Certificate of Sale given to the purchaser, and, if no redemption occurs within one year, a Final Bill of Sale conveying title to the purchaser.

Requiron presented none of these. He offered only the testimony of the municipal treasurer and a "Certificate of Repurchase After Sale" — a document that actually contradicted his claim.

Key Flaws in the Buyer's Claim

The Court identified several fatal problems with Requiron's position:

• Payment before the auction was not a valid bid. A bid must be made during the auction period. Before the scheduled sale, the property was not yet for sale, and the owner still had the right to pay the taxes and stop the auction.
• Partial payment suspends the auction. Under Section 36 of Commonwealth Act No. 470, a taxpayer may stay the sale by paying the taxes and penalties due. The defendants' partial payment, accepted by the provincial treasurer, was substantial compliance — regardless of whether the municipal treasurer received the suspension message.
• The Certificate of Repurchase contradicted his claim. This document stated that the province of Negros Occidental bought the property at the auction and that Requiron repurchased it in behalf of Catalino Javello — not that Requiron was the winning bidder. The document also contained internal inconsistencies, such as stating that payment was made before the auction even occurred.
• He admitted buying the property from the heirs. Requiron himself admitted he purchased the property from the heirs of Catalino Javello in April 1974, which the Court found illogical if he had already bought it at auction.

The Underlying Ownership Dispute

The Court also upheld the Court of Appeals' finding that the defendants were the lawful owners of the property. Their claim was supported by notarized deeds of sale, while the plaintiffs' claim of a verbal lease was supported only by testimony. The alleged forgery of the deeds was disproved by dactyloscopic reports and the testimony of the notary public, who explained the discrepancies as clerical errors.

Practical Takeaways

• A tax sale is a strict proceeding. The buyer must prove every step — the notice, the auction, the award, and the issuance of the required certificates. The presumption of regularity does not apply when the result is the loss of one's property.
• Payment before the auction is not a bid. To participate in a tax auction, tender your bid during the scheduled auction period. Paying the delinquent taxes beforehand simply stops the sale.
• Partial payment can suspend the auction. Even a partial payment of the tax delinquency, accepted by the treasurer, may be substantial compliance with the law and should halt the sale.
• Know the required documents. A valid tax sale under Commonwealth Act No. 470 requires a Report of Sale, a Certificate of Sale, and, after the redemption period, a Final Bill of Sale. A "Certificate of Repurchase" is not the same as a Certificate of Sale — it is given to the taxpayer who redeems the property, not to the winning bidder.
• If you buy property from an owner, don't also claim to have bought it at auction. Inconsistent claims will undermine your case and cast doubt on your evidence.
