Can a Subcontractor Sue the Project Owner Directly? CIAC Jurisdiction Explained

Subcontractors can claim unpaid amounts from project owners under Article 1729, but the dispute must go through CIAC arbitration, not regular courts.


Subcontractors who are unpaid for their work often wonder whether they can sue the project owner directly, even without a direct contract. Philippine law gives them a right to claim payment from the owner under Article 1729 of the Civil Code. However, the Supreme Court recently clarified that this right must be enforced through construction arbitration, not before regular courts.

In Grandspan Development Corporation v. Franklin Baker, Inc. and Advance Engineering Corporation (G.R. No. 251463, August 2, 2023), the Court ruled on how Article 1729 interacts with the jurisdiction of the Construction Industry Arbitration Commission (CIAC).

The Case

Franklin Baker, Inc. (FBI) hired Advance Engineering Corporation (AEC) as contractor to build a coconut processing plant. AEC then subcontracted part of the work to Grandspan Development Corporation. When AEC failed to pay Grandspan in full, Grandspan sued both AEC and FBI before the Regional Trial Court.

Grandspan impleaded FBI under Article 1729 of the Civil Code, which states that those who furnish labor or materials for a piece of work undertaken by a contractor have an action against the owner up to the amount owing from the owner to the contractor at the time the claim is made.

Both contracts contained arbitration clauses. The trial court dismissed the case, ruling that the disputes should be referred to arbitration. The Court of Appeals affirmed, and the Supreme Court agreed.

The Key Rulings

Article 1729 creates a real right against the owner. The Court explained that this provision creates a "constructive vinculum" or contractual privity between the owner and those who furnish labor or materials. This is an exception to the general rule that contracts only bind the parties to them. The owner's liability is solidary with the contractor, and the owner's only defense is to prove full payment to the contractor.

The burden of proving payment falls on the owner. The Court rejected the argument that the subcontractor must first prove the owner still owes the contractor. Instead, the owner must assert and prove that it has already paid the contractor in full. This protects subcontractors who have no access to the details of the owner-contractor arrangement.

Article 1729 was not repealed by Executive Order No. 1008. The Court found that the law creating the CIAC did not expressly repeal Article 1729. The two provisions can exist in harmony: Article 1729 gives the substantive right to claim, while E.O. No. 1008 determines where the claim must be heard.

The claim must be filed with the CIAC, not regular courts. Because the subcontractor's claim arises from a construction contract containing an arbitration clause, the dispute falls under the CIAC's original and exclusive jurisdiction. The Court noted that a subcontractor is effectively an assignee of the construction contract, and Section 35 of the Alternative Dispute Resolution Act of 2004 (R.A. No. 9285) expressly covers disputes among project owners, contractors, and subcontractors.

Practical Takeaways

  • A subcontractor can claim unpaid amounts directly from the project owner, even without a direct contract with the owner.
  • The owner cannot simply deny liability; it must prove that it has already paid the contractor in full.
  • These claims must be brought before the CIAC, not regular courts, if the contracts contain arbitration clauses.
  • Even if the subcontractor has no privity with the owner, the CIAC can hear the claim against both the contractor and the owner in one proceeding.
  • Subcontractors should check their subcontract agreements for arbitration clauses and be prepared to arbitrate before the CIAC.
