Quantum Meruit: When a Contractor Can Recover Payment Without a Formal Contract

In the construction industry, the absence of a formal written contract often raises a critical question: can a contractor still get paid for work already done? The Supreme Court addressed this in F.F. Mañacop Construction Co., Inc. v. Court of Appeals and Manila International Airport Authority (G.R. No. 122196, January 15, 1997), clarifying when the equitable principle of quantum meruit applies — even against a government agency.

The Facts of the Case

In September 1985, F.F. Mañacop Construction began building a perimeter fence along the Manila International Airport (MIA) road for a quoted price of P307,440.00. The project was urgent: the fence was meant to prevent squatters from entering the airport area.

The contractor proceeded with construction even though the Notice to Proceed had not yet been signed by the general manager. It had only been initialed by the Assistant Project Manager. After the February 1986 revolution, however, a new general manager stopped the construction. By that time, 95% of the fence was finished, worth P282,068.00 as computed by the contractor.

The contractor made repeated demands for payment over two years, but the airport authority ignored them. The contractor then went to court.

The Issue

The case presented two main questions: First, could the contractor recover payment without a formal written contract? Second, should the determination of the amount due be referred to the Commission on Audit (COA) instead of the courts?

The Ruling: Quantum Meruit Applies

The Supreme Court ruled in favor of the contractor, applying the principle of quantum meruit. This Latin term means "as much as he reasonably deserves." It allows a party to recover the reasonable value of services rendered, regardless of whether there was an agreement on the price.

The Court found that a quasi-contractual relationship existed between the contractor and the airport authority. The contractor had rendered services that benefited the government agency, and it would be unjust to deny payment.

When Can a Contractor Recover Without a Formal Contract?

The Court identified several factors that justified recovery on a quantum meruit basis:

• No fraud or illegality: The quasi-contract was neither fraudulent nor mala in se (wrong in itself).
• Funds were appropriated: The project was covered by a specific appropriation of P313,325.28.
• Implied obligation to pay: As in private contracts, the facts showed the government had an implied obligation to pay.
• Within legal powers: The property or benefit was not ultra vires — it could be the proper subject of an express contract.
• Public necessity: The case fell within exceptions to mandatory public bidding, where urgency or time is of the essence.
• Substantial compliance: The contractor completed 95% of the work in good faith, with no intentional departure from specifications.
• Equity supports the claim: The airport authority was reaping benefits from the fence the contractor built.
• No collusion: There was no proof of fraud or collusion among the parties.

Courts, Not COA, Determine Quantum Meruit Claims

The airport authority argued that the amount due should be determined by the COA, citing previous cases. The Supreme Court disagreed. It explained that quantum meruit claims are unliquidated — they require the application of judgment and discretion, not simple arithmetic. These are justiciable questions ripe for judicial determination.

The Court noted that in the cases cited by the airport authority, the exact amount was not at issue. Here, the trial court had already made a factual finding on the reasonable amount due and had scrutinized the evidence. Courts, being courts of both law and equity, are not powerless to determine such factual matters.

Practical Takeaways

• Document everything: Even without a formal contract, keep records of plans, photographs, material certifications, and correspondence showing the work performed.
• Good faith matters: Courts are more likely to award quantum meruit recovery when the contractor acted in good faith and substantially complied with the project specifications.
• Urgency can justify proceeding: When time is of the essence or public necessity requires immediate action, proceeding without a signed contract may still allow recovery.
• Government agencies can be held liable: The government can be bound by implied obligations to pay for benefits it receives, provided there is no fraud or collusion.
• Courts can determine the amount: A quantum meruit claim does not automatically have to be referred to the COA; courts can decide the reasonable value of services rendered.
