Mortgage Validity and Foreclosure: Protecting Property Rights Under Philippine Law

The Supreme Court’s 2009 decision in National Investment and Development Corporation v. Spouses Bautista (G.R. No. 150388) clarifies important rules on mortgage validity, extrajudicial foreclosure, and the right of redemption. The case arose from a decades-long property dispute involving several lots in Quezon City, and its rulings continue to guide how courts treat mortgages made by non-owners, the timing of redemption, and the binding effect of earlier judgments.

The Facts of the Case

Spouses Francisco and Basilisa Bautista owned a 6,368-square-meter lot in Quezon City. In 1963, they sold an 822-square-meter portion of it to Araceli Del Rosario. However, the title issued in Del Rosario’s name covered the entire lot, not just the portion she bought. A new title was later issued in the names of both the spouses and Del Rosario.

Del Rosario then mortgaged the entire lot to the Philippine Commercial and Industrial Bank (PCIB) to secure a loan. When she defaulted, PCIB foreclosed and bought the property at auction, then assigned its rights to the National Investment and Development Corporation (NIDC).

Meanwhile, the Bautistas sued to rescind the sale to Del Rosario. The court granted rescission but ruled that the Bautistas took the property subject to PCIB’s mortgage, which was made in good faith. That decision became final.

Years later, the Bautistas obtained a loan from Banco Filipino and mortgaged the same lot—including the portion they claimed they never intended to encumber—as security. When they defaulted, Banco Filipino foreclosed and bought the property. NIDC then paid Banco Filipino to acquire the property, believing it was exercising its right of redemption.

The Bautistas sued to recover a 5,546-square-meter portion of the lot, arguing that Del Rosario had no right to mortgage it and that NIDC’s acquisition was invalid.

The Issue

The central question was whether NIDC validly acquired the disputed portion of the lot. This required the Court to determine whether Del Rosario could mortgage property she did not own, whether the earlier judgments barred the Bautistas from raising this issue, and whether NIDC’s payment to Banco Filipino was a valid redemption.

The Ruling

The Supreme Court ruled in favor of NIDC, reversing the Court of Appeals.

First, the Court applied the doctrine of res judicata (bar by prior judgment). The earlier cases had already settled that PCIB was a mortgagee in good faith and that its assignment of rights to NIDC was valid. The Bautistas could not relitigate these matters.

Second, the Court clarified that Del Rosario could not validly mortgage the 5,546-square-meter portion because she was not its owner. Under Article 2085 of the Civil Code, a mortgagor must be the absolute owner of the property; otherwise, the mortgage is void. However, the Court found that the Bautistas themselves later mortgaged the entire lot to Banco Filipino, and the evidence showed they intended to include it as security.

Third, the Court addressed the redemption issue. Under Section 6 of Republic Act No. 3135, as amended, the debtor has one year from the registration of the certificate of sale to redeem foreclosed property. Here, the certificate was registered on 27 October 1971, so the redemption period ended on 26 October 1972. NIDC’s payment on 27 October 1972 came one day too late. By then, Banco Filipino had become the absolute owner and could sell the property to NIDC as an ordinary sale.

Practical Takeaways

• A mortgage over property the mortgagor does not own is void. Before accepting a mortgage, lenders should verify ownership through the certificate of title.
• Prior judgments bind the parties. Issues already decided in a final judgment cannot be raised again in a later case between the same parties.
• The redemption period is strictly counted. Under RA 3135, the one-year period runs from registration of the certificate of sale, and missing the deadline by even one day extinguishes the right to redeem.
• After the redemption period lapses, the foreclosure buyer becomes the absolute owner. The property may then be sold freely, and the transaction is treated as an ordinary sale.
• Documentation matters. A party claiming a property was included in a mortgage by mistake should object promptly; silence and subsequent offers to repurchase can be treated as evidence of intent.
