Unregistered Real Estate Mortgages: Valid Between Parties Despite Formal Defects

The Supreme Court recently clarified a crucial point in Philippine property law: a real estate mortgage (REM) that is defective in form—such as improper notarization or failure to comply with registration formalities—remains valid and binding between the parties who signed it. In Coca-Cola Bottlers Phils., Inc. v. Spouses Efren and Lolita Soriano (G.R. No. 211232, April 11, 2018), the Court reversed lower court decisions and upheld the validity of a mortgage despite significant procedural defects, providing important guidance for lenders, borrowers, and property owners.

The Facts of the Case

The respondents, spouses Efren and Lolita Soriano, were distributors of Coca-Cola products in Tuguegarao City. In 1999, Coca-Cola, through its general manager Reynaldo Cipriano, required security for the continuation of their business. The Sorianos surrendered two certificates of title over their property and signed a document, allegedly assured that it was "a mere formality" and would never be notarized.

When the Sorianos later decided to stop selling Coca-Cola products and demanded the return of their titles, they discovered that their land had been mortgaged to Coca-Cola and had already been foreclosed. They filed a complaint to annul the foreclosure sale, claiming they never signed a mortgage document, were never notified of the foreclosure, and had no outstanding debts with the company.

The Regional Trial Court nullified the mortgage and foreclosure, and the Court of Appeals affirmed, ruling that the REM deed failed to comply substantially with the required form. The CA noted that the Sorianos never acknowledged the deed before the notary, only one witness signed instead of the required two, and the notarization was done by a Clerk of Court who lacked authority.

The Issue

The central question before the Supreme Court was whether a real estate mortgage remains valid between the parties when the deed was: (1) admittedly signed by the mortgagors, but in a place other than stated in the document, and (2) notarized without authority and without compliance with the prescribed form under Section 112 of Presidential Decree No. 1529.

The Ruling: Registration Is Not Essential to Validity

The Supreme Court granted the petition and ruled in favor of Coca-Cola, holding that the mortgage was valid between the parties. The Court emphasized that registration of a REM deed is not essential to its validity.

The Court cited Article 2125 of the Civil Code, which provides that "in addition to the requisites stated in Article 2085, it is indispensable, in order that a mortgage may be validly constituted, that the document in which it appears be recorded in the Registry of Property. If the instrument is not recorded, the mortgage is nevertheless binding between the parties."

The Court also relied on earlier jurisprudence, including Paradigm Development Corporation of the Philippines v. Bank of the Philippine Islands (G.R. No. 191174, June 7, 2017) and Mobil Oil Philippines, Inc. v. Diocares (140 Phil. 171 [1969]), which established that even without registration, a mortgage binds the parties who executed it.

Defective Notarization: Effect on the Document

The Court acknowledged that the notarization in this case was defective—the Clerk of Court of the RTC of Ilagan was not authorized to notarize private documents unrelated to his official functions. However, the Court clarified that defective notarization merely strips the document of its public character and reduces it to a private document.

Under Article 1358 of the Civil Code, while contracts transmitting or extinguishing real rights over immovable property should be in a public document, the failure to observe this form does not render the transaction invalid. The requirement is only for convenience, not essential for validity or enforceability.

When a document's notarization is defective, the evidentiary standard shifts. Instead of the clear and convincing evidence standard attached to duly-notarized documents, the document is tested by preponderance of evidence under Section 20, Rule 132 of the Rules of Court, which requires proof of due execution and authenticity.

The Issue of Fraud

The Sorianos argued that they were induced to sign through fraud—they were told the document would not be notarized. The Court rejected this argument, noting that the respondents admitted signing the REM deed and surrendering their titles. Their claim of fraud was a bare allegation unsupported by preponderance of evidence.

Drawing from PDCP v. BPI and Ocampo v. Land Bank, the Court held that even if the mortgagee reneged on a promise not to register the mortgage, this amounts at most to dolo incidente (incidental fraud), which does not avoid a contract. The admission of signing the deed, coupled with surrendering the titles, proved no fraud existed in the execution of the contract.

Practical Takeaways

• Registration is for third-party protection, not validity. An unregistered real estate mortgage is fully valid and binding between the parties who executed it. Registration primarily protects the mortgagee's rights against third persons claiming an interest in the property.

• Defective notarization does not void the mortgage. A mortgage deed with defective notarization is reduced to a private document but remains enforceable between the parties. The burden shifts to proving due execution through preponderance of evidence.

• Admissions are powerful evidence. If a party admits signing a mortgage document, they cannot later claim the document is void simply because of formal defects. Claims of fraud must be supported by clear evidence.

• Be careful with "mere formality" assurances. Signing a document and surrendering titles can bind a property owner, even if they were assured the document would not be notarized or registered. Always read and understand documents before signing.

• Foreclosure validity follows the mortgage. If the mortgage is valid, the foreclosure sale conducted pursuant to it is also valid, provided the statutory notice requirements under Act No. 3135 are satisfied.
