Unsigned Stipulations in Mortgages: Philippine Supreme Court Upholds Consent as Key

The Supreme Court's 2006 decision in Pilipinas Bank v. Glee Chemical Laboratories, Inc. (G.R. No. 148320) reaffirms a fundamental principle in Philippine contract law: a contract binds only those who gave their consent. When a bank inserts a third-party liability clause into a mortgage after the borrower has already signed, without the borrower's knowledge or approval, that stipulation is null and void. The case serves as a cautionary tale for both lenders and borrowers about the importance of reading documents carefully and the legal consequences of altering contracts after execution.

The Facts of the Case

Glee Chemical Laboratories, Inc. applied for a loan of P800,000.00 from Pilipinas Bank, secured by a real estate mortgage over its property in San Juan, Metro Manila. The mortgage, dated March 5, 1982, stated the loan was for "additional working capital for the purchase of fertilizers."

The dispute arose when the bank never delivered the loan proceeds to Glee Chemical. Instead, the bank applied the amount to settle a debt owed by a certain Rustica Tan. The bank claimed this was proper because the mortgage contained a "third-party liability" stipulation making the property security for Rustica Tan's obligations.

Glee Chemical's president, Cheng Yong, testified that when he signed the pre-printed mortgage form, the blank spaces were empty. The name "Rustica Tan" and the "Third-Party Liability" clause were typed in only after he affixed his signature. The bank's own witness, a loans clerk, admitted he typed the stipulation on March 4, 1982, a day before presenting the document for signature—but also admitted that when the document was notarized, Cheng Yong and the witness were not present before the notary public.

The Issue

The central question was whether the stipulation pour autri—a stipulation in favor of a third person—was validly inserted into the mortgage with the mortgagor's consent. Under Philippine law, a stipulation pour autri requires that it be the purpose and intent of the contracting parties to benefit the third person. As the Court cited in Bank of the Philippine Islands v. V. Concepcion e Hijos, Inc. (53 Phil. 806, 817 [1928]), it is not enough that the third person may be incidentally benefited.

The Ruling

The Supreme Court denied the bank's petition, affirming the decisions of both the trial court and the Court of Appeals. The Court held that the unconsented insertion of the third-party liability clause effectively changed the nature of the instrument. Without Glee Chemical's consent to this alteration, the stipulation was null and void ab initio.

The Court applied the well-settled rule that factual findings of the trial court, especially when affirmed by the Court of Appeals, are final and conclusive unless they fall under recognized exceptions. None of those exceptions applied here. The trial court, which had the best opportunity to observe the witnesses' demeanor, found Cheng Yong's testimony more credible than the bank clerk's.

Significantly, the Court noted that the notarization of the document did not save the bank's position. The presumption that official duty has been regularly performed is rebuttable under Section 3, Rule 131 of the Revised Rules of Court. The bank's own witness destroyed this presumption by admitting that Cheng Yong and his witness never appeared before the notary public. The notary's acknowledgment was therefore a false statement, rendering the notarization useless.

Practical Takeaways

• Consent is the foundation of every contract. A stipulation inserted after signing, without the mortgagor's knowledge, is void. Always read the final version of any document before signing, and ensure no blanks are left unfilled.

• Notarization is not conclusive proof of validity. A notarized document carries a presumption of regularity, but that presumption can be overcome by evidence that the parties did not actually appear before the notary.

• Banks must ensure borrowers consent to third-party liability clauses. A stipulation pour autri is valid only if the contracting parties intended to benefit the third person. Lenders cannot simply insert such clauses after execution and expect them to be enforced.

• Witnesses matter. The credibility of witnesses, as assessed by the trial court, is given great weight on appeal. Parties should present clear, consistent testimony to support their version of events.

• For borrowers facing foreclosure on unauthorized terms: The remedy is to challenge the validity of the mortgage in court and seek injunctive relief to stop the foreclosure sale while the case is pending.
