Mortgagor Ownership and Estoppel: When a Real Estate Mortgage Stays Valid

The Supreme Court’s 2012 decision in Philippine National Bank v. Spouses Reblando (G.R. No. 194014) clarifies two important points for anyone dealing with real estate mortgages: a mortgagor who benefits from a loan cannot later attack the mortgage’s validity, and courts will look at the totality of evidence—not just one document—to determine ownership of mortgaged property.

The case involved a loan of PhP 150,000 obtained by the spouses Reblando from PNB in January 1992, secured by a real estate mortgage over two parcels of land in General Santos City. One lot was covered by a Transfer Certificate of Title; the other, Lot No. 10, was covered only by a Tax Declaration in Alejandro Reblando’s name. The mortgage contract included a supplemental page describing Lot No. 10.

Over the years, the loan was increased twice through amendments to the mortgage, eventually reaching PhP 312,000. When the spouses defaulted, PNB foreclosed and bought both lots at the auction sale. After the redemption period lapsed and PNB consolidated ownership, the spouses sued to nullify the mortgage over Lot No. 10, claiming they were not its owners when the mortgage was constituted.

The Issue

The core question was whether the mortgage over Lot No. 10 was valid, given the requirement under Article 2085 of the Civil Code that a mortgagor must be the absolute owner of the mortgaged property.

The Ruling

The Supreme Court reversed the lower courts and upheld the mortgage. It made three key findings.

First, both lots were mortgaged simultaneously on January 28, 1992. The spouses had attached only part of the mortgage contract to their complaint, omitting the supplemental page that described Lot No. 10. The Court noted that an annotation on the contract itself referred to an “additional collateral at the supplemental page,” and a tax declaration annotation dated the day after the mortgage confirmed that Lot No. 10 was mortgaged to PNB. Being a notarized public document, the mortgage enjoyed the presumption of regularity.

Second, Alejandro Reblando was the declared owner of Lot No. 10 at the time of the mortgage. The Tax Declaration in his name was issued in September 1990, about two years before the mortgage. He was also in actual possession of the property, with his residence built on it. The Court held that tax declarations and receipts, coupled with actual possession, are prima facie proof of ownership.

The spouses relied on a Contract to Sell they signed with the Bliss Development Corporation in 1995 for “Unit No. 10.” But the Court found this document covered a dwelling unit, not the land itself. It had nothing to do with the mortgage and could not prove the government owned Lot No. 10.

Third, the spouses were estopped from denying the mortgage’s validity. Under Section 2(a), Rule 131 of the Rules of Court, a party who deliberately leads another to believe something true cannot later falsify it. The spouses took the loan, defaulted, let the property be foreclosed, and only then attacked the mortgage. The Court warned against the practice of obtaining loans, defaulting, and then contesting the mortgage to avoid payment.

Practical Takeaways

• A mortgagor who benefits from a loan is generally estopped from later claiming the mortgage is void, absent proof of fraud or coercion by the bank.
• Tax declarations, coupled with actual possession, can serve as prima facie evidence of ownership sufficient to support a valid mortgage.
• A notarized mortgage contract enjoys the presumption of regularity; a party challenging it needs clear and convincing evidence.
• Omitting material pages of a contract or submitting unrelated evidence to mislead courts can seriously damage a party’s credibility.
• When reviewing a mortgage, examine the entire contract—including supplemental pages and annotations—to determine what property was actually covered.
