Written Stipulation Is Key: Enforceability of Loan Interest Agreements in the Philippines

The Supreme Court's ruling in Federal Builders, Inc. v. Foundation Specialists, Inc. (G.R. No. 194507, September 8, 2014) provides crucial guidance on when the 12% legal interest rate applies in the Philippines. The case clarifies the distinction between obligations involving loans or forbearance of money—which may carry 12% interest—and ordinary service contracts, which are subject to only 6%. For businesses and individuals entering into agreements, this distinction underscores the critical importance of written stipulations on interest.

The Facts of the Case

In August 1990, Federal Builders, Inc. (FBI) engaged Foundation Specialists, Inc. (FSI) as subcontractor for the construction of a diaphragm wall, capping beam, and guide walls for the Trafalgar Plaza in Makati City. The contract price was P7,400,000.00, with FBI obligated to make progress payments every fifteen days.

FSI completed 97% of the contracted works but FBI refused to pay Billings No. 3 and 4, amounting to over P1.6 million. FBI claimed FSI's work was defective and that it had to spend over P8.5 million on remedial works. FSI sued for collection, and both the Regional Trial Court and Court of Appeals ruled in FSI's favor, awarding the unpaid billings plus 12% interest from August 30, 1991.

The Issue Before the Supreme Court

The central legal question was whether the 12% interest rate imposed by the lower courts was correct. FBI argued that since the agreement contained no stipulation on interest and was not a loan or forbearance of money, the 12% rate should not apply.

The Supreme Court's Ruling

The Court affirmed FBI's liability for the unpaid billings but modified the interest rate from 12% to 6% per annum. The Court explained that the 12% rate applies only to obligations involving loans or forbearance of money. A "forbearance" refers to a contractual obligation where a lender or creditor refrains from requiring repayment of a loan or debt during a given period.

The construction agreement between FBI and FSI was not a loan or forbearance of money—it was a contract for services. The Court noted that FSI performed construction work, not an acquiescence to the temporary use of money. Since the contract had no written stipulation on interest, the applicable rate was 6% per annum under Article 2209 of the Civil Code.

The Role of Written Stipulations

The Court reiterated that when an obligation involves a loan or forbearance of money, the interest due should be that stipulated in writing. In the absence of a written stipulation, the rate is 12% per annum from default. However, for non-loan obligations like construction contracts, the rate is 6% per annum.

The Court also clarified the effect of Bangko Sentral ng Pilipinas Monetary Board Circular No. 799, which reduced the legal interest rate to 6% for loans effective July 1, 2013. This new rate applies prospectively, not retroactively.

Practical Takeaways

• Put interest terms in writing. If parties intend to charge interest on unpaid amounts, the rate must be expressly stipulated in the contract. Oral agreements on interest are difficult to enforce.
• Know the distinction. A contract for services, such as construction, is not a loan or forbearance of money. The default interest rate for breach of such contracts is 6%, not 12%.
• Demand matters. Interest begins to run from the date of judicial or extrajudicial demand when the obligation is breached and the amount is established with reasonable certainty.
• Check the applicable rate. For obligations involving loans, the rate is 12% per annum if no rate was stipulated and the obligation arose before July 1, 2013. After that date, the rate is 6%.
• Document everything. In construction disputes, courts rely heavily on documentary evidence. Proper documentation of billings, demands, and communications can significantly affect the outcome.
