Philippine Contract Law: When Written Agreements Prevail Over Verbal Claims

In the Philippines, disputes often arise when one party claims that a written contract does not reflect what the parties truly agreed upon. The Supreme Court case of Gold Loop Properties, Inc. v. Court of Appeals and Philippine International Trading Corporation (G.R. No. 127367, May 3, 1999) provides a clear and instructive answer: when the terms of a written agreement are clear and unambiguous, courts will uphold them over self-serving claims of a different, unwritten understanding. This case is a cornerstone for anyone who signs a contract, highlighting the binding nature of written stipulations.

The Facts: From Barter to a Credit Sale

The dispute began with two business transactions between Gold Loop Properties, Inc. (GLP) and the Philippine International Trading Corporation (PITC). In the first, GLP exchanged ten condominium units for cement in a straightforward barter or "swap." The controversy, however, centered on a second transaction involving additional cement.

GLP offered to buy more cement, and in April 1991, the parties signed a Memorandum of Agreement (MOA). This MOA was detailed, stipulating that GLP would purchase the cement on credit for P2,250,000.00. To secure payment, GLP issued a post-dated check, a promissory note, and a real estate mortgage. The MOA also contained a key provision (Section 2.5) allowing GLP to offer a condominium unit as payment instead of cash, but only if the offer was made within three months and if PITC accepted it.

When the check matured, it bounced due to insufficient funds. GLP failed to pay, leading PITC to file a collection case.

The Issue: Was It a Swap or a Sale?

GLP argued that the real agreement was still a "swap." They claimed the MOA was merely a formality to satisfy government audit requirements and that the true intent was to exchange another condominium unit for the cement. They pointed to the earlier barter transaction and to a letter where PITC seemed amenable to the idea of a swap.

The central issue was whether the written MOA, which clearly outlined a sale on credit, could be overturned by GLP's verbal claims and testimony about a different, unwritten agreement to barter.

The Ruling: The Written Contract Governs

The Supreme Court denied GLP's petition and affirmed the decisions of the lower courts. The Court ruled that the MOA was the final and binding contract between the parties. It found the terms of the MOA to be clear and unambiguous, explicitly describing a sale on credit, not a barter.

The Court emphasized that the "swapping" provision in the MOA was only an option for GLP to offer a unit, which PITC was not obligated to accept. Since PITC did not accept the offer, GLP's obligation to pay in cash remained. The Court also rejected GLP's attempt to introduce testimony to contradict the written terms, invoking the parol evidence rule. This rule, found in the Rules of Court, generally prohibits a party from presenting extrinsic evidence to vary, contradict, or add to the terms of a written agreement that is clear on its face.

The Parol Evidence Rule in Practice

The Court's decision reinforces a fundamental principle in Philippine contract law: a written agreement is the best evidence of the parties' intent. Allowing parties to later claim a different verbal understanding would make written contracts unstable and unreliable. The Court noted that while a prior letter mentioned a "swap," the final MOA was executed after that letter and contained the definitive terms. The final written contract superseded any preliminary discussions or drafts.

Practical Takeaways

• Read Before You Sign: Every word in a contract matters. The MOA's clear language describing a "sale on credit" was decisive. GLP's failure to fully appreciate the implications of the "option" clause was fatal to its case.
• Get It in Writing: If an agreement is important, it must be in writing. Verbal promises or preliminary letters, like the March 25, 1991 letter, are generally not binding if they are contradicted by a later, more formal written contract.
• "May" Means Optional: In contract interpretation, the word "may" is generally permissive, not mandatory. GLP had the option to offer a condominium, but PITC was not obligated to accept it.
• Extrinsic Evidence Has Limits: The parol evidence rule prevents a party from using testimony to change the clear terms of a written contract. This rule protects the stability and integrity of written agreements.
• Personal Liability is Real: Signing a contract in a personal capacity, as the corporate officers did in the promissory note, can create personal, solidary liability, making them jointly responsible for the corporate debt.
