Privity of Contract in the Philippines: Why Third Parties Are Not Bound by Your Agreement

Privity of contract is a foundational principle in Philippine civil law: a contract generally binds only the parties who entered into it. If you are not a signatory to an agreement, you typically cannot enforce it—and you cannot be bound by it. This principle has significant consequences in commercial transactions, particularly when banks are involved.

The Supreme Court's decision in Villalon v. Court of Appeals illustrates how this doctrine protects financial institutions from obligations arising from private agreements they were never part of. The case remains a valuable guide for anyone dealing with assignments, letters of credit, and third-party rights.

The Legal Foundation: Article 1311 of the Civil Code

The doctrine of privity of contract is rooted in Article 1311 of the Civil Code of the Philippines, which provides that contracts take effect only between the parties, their assigns, and heirs. The article also recognizes an exception: a stipulation in favor of a third person, known as stipulation pour autrui.

For this exception to apply, three conditions must be met:

• The contracting parties must have clearly and deliberately conferred a benefit upon a third person—a mere incidental benefit is not enough.
• The third party must communicate acceptance to the obligor before the stipulation is revoked.
• The benefit must be intentional, not merely a by-product of the contract.

This framework protects the autonomy of contracting parties. It ensures that individuals and entities are not inadvertently bound by agreements they did not consent to, while still allowing parties to extend benefits to third persons when they clearly intend to do so.

The Villalon Case: A Partnership, a Letter of Credit, and Two Assignments

The facts of Villalon illustrate how privity operates in practice.

Andres Villalon entered into a partnership with Benjamin Gogo Jr. to export wood products. Villalon invested P207,500 as the capitalist partner, while Gogo contributed his existing export business, Greenleaf Export, as the industrial partner. To secure Villalon's investment, Gogo executed a Deed of Assignment of Proceeds assigning to Villalon the proceeds of Letter of Credit No. 25-35298/84, valued at $46,500.

Unknown to Villalon, Gogo later obtained two Packing Credit Lines from the Insular Bank of Asia and America (IBAA), now Philippine Commercial International Bank (PCIB), totaling P100,000. Gogo used the same letter of credit as collateral and executed a separate Deed of Assignment in favor of the bank.

When IBAA negotiated portions of the LC and released the proceeds to Gogo—after deducting loan repayments—Villalon sued the bank. He argued that IBAA should have honored his prior assignment and paid him instead.

The Courts' Ruling: No Duty Without Privity

The Regional Trial Court dismissed Villalon's complaint against IBAA, finding no evidence that the bank was notified of the assignment to Villalon before granting Gogo's loans. The Court of Appeals affirmed, emphasizing that IBAA was not a party to the assignment between Villalon and Gogo.

The Supreme Court upheld these rulings. The Court emphasized that IBAA, being a stranger to the agreement between Villalon and Gogo, could not be bound by it. Since the bank was not notified of the first assignment, it was justified in dealing with Gogo—the beneficiary of the letter of credit—as the party entitled to the proceeds.

The case underscores a critical point: a bank's obligations are defined by its direct agreements and documented instructions, not by private arrangements between its clients.

Practical Implications for Businesses and Individuals

The Villalon case offers several lessons for anyone involved in contracts, assignments, or financial transactions:

Privity of contract matters. Do not assume that a contract will bind parties who are not signatories. Banks and other institutions act based on their direct agreements with their clients.

Notification is key. To bind a third party, provide formal, documented notice. Alleged initials on a document, without proper authentication, are insufficient proof of notification.

Conduct due diligence. Before entering partnerships or investments, understand your partner's existing financial arrangements, especially regarding assets used as collateral.

Use direct agreements. If you intend to create rights for a third party, make them a party to the contract or use a separate agreement they acknowledge and accept.

Document everything. Maintain clear, verifiable records of all agreements, notifications, and acknowledgments. Ambiguity weakens your legal position.

Practical Takeaways

• A contract binds only its parties and their assigns or heirs—unless a clear stipulation pour autrui exists.
• Banks are not automatically bound by private agreements between clients, even if those agreements involve the same subject matter.
• Formal, documented notification to a third party is essential to create enforceable rights against them.
• A Deed of Assignment involving bank transactions should be formally provided to the bank, with acknowledgment obtained.
• When in doubt, bring the third party into the agreement or secure their written acceptance.
