Novation Requires Unequivocal Terms: Asian Construction vs Mero Structures

Asian Construction and Development Corporation v. Mero Structures, Inc. (G.R. No. 221147, September 29, 2021) is a useful reminder for businesses about the strict requirements for novation — the substitution of an obligation with a new one. The Supreme Court ruled that a simple exchange of letters allowing a supplier to collect payment directly from a project owner did not extinguish the contractor's obligation to pay. For novation to occur, the intent must be clear and unequivocal.

The Dispute

In 1998, First Centennial Clark Corporation (FCCC) engaged Asian Construction and Development Corporation (Asiakonstrukt) to build structures for the Philippine Centennial Exposition. Asiakonstrukt then contracted MERO Structures, Inc. to supply a spaceframe for a Philippine flag structure for US$570,000.00.

MERO delivered the materials, but Asiakonstrukt did not pay. In October 1999, MERO wrote to Asiakonstrukt requesting permission to collect payment directly from FCCC. Asiakonstrukt replied in November 1999 that it had no objection to this arrangement.

When payment still did not come, MERO sued Asiakonstrukt and FCCC. Asiakonstrukt argued that the 1999 letters constituted novation — that MERO had effectively substituted Asiakonstrukt as the party entitled to collect from FCCC, thereby extinguishing Asiakonstrukt's own obligation to MERO.

The Issue

Did the exchange of letters between MERO and Asiakonstrukt create a new contract that novated (extinguished) Asiakonstrukt's obligation to pay MERO?

The Ruling

The Supreme Court held that no novation occurred. Asiakonstrukt remained obligated to pay MERO the US$570,000.00 plus interest.

The Court explained that under Article 1292 of the Civil Code, for an obligation to be extinguished by a new one, it must be declared in "unequivocal terms," or the old and new obligations must be incompatible on every point. Neither was present here.

First, nothing in the letters stated that Asiakonstrukt's obligation to pay MERO was being extinguished. Second, the letters did not say MERO was being subrogated to Asiakonstrukt's rights against FCCC. At most, Asiakonstrukt merely allowed MERO to try collecting from FCCC directly — an alternative mode of payment, not a substitution of debtor.

The Court also stressed that FCCC, the third party, never consented to any substitution. Under Article 1293 of the Civil Code, substituting a new debtor requires the creditor's consent — and here, FCCC was not even a party to the letters.

The Takeaway on Novation

The Court reiterated the four requisites for novation from Garcia v. Llamas (462 Phil. 779 [2003]): (1) a previous valid obligation; (2) agreement to a new contract; (3) extinguishment of the old contract; and (4) a valid new contract.

Crucially, novation is never presumed. A party claiming that an obligation has been novated bears the burden of proving it with clear evidence.

Practical Takeaways

• Novation must be explicit. If parties intend to substitute a debtor or creditor, the agreement should state in clear terms that the original obligation is extinguished and replaced.
• Mere permission is not novation. Allowing a creditor to seek payment from a third party does not release the original debtor from liability.
• Third-party consent is essential. A valid substitution of debtor requires the consent of the creditor — and, in cases of delegation, the new debtor as well.
• Document carefully. When restructuring payment arrangements, use a formal agreement that specifies whether the original obligation survives. Vague letters can create disputes.
• Risk allocation matters. A contractor who subcontracts work assumes the risk of the project owner's nonpayment unless the contract clearly conditions payment on receipt from the owner.
