Surety Bonds and Legal Interest: When Default Makes a Surety Pay More Than the Bond

The Supreme Court has long held that a surety's liability is generally limited to the amount stated in the bond. But what happens when the surety refuses to pay upon demand? In Commonwealth Insurance Corporation v. Court of Appeals and Rizal Commercial Banking Corporation (G.R. No. 130886, January 29, 2004), the Court clarified that a defaulting surety may be held liable for legal interest that exceeds the bond's face value.

The Facts of the Case

In 1984, Rizal Commercial Banking Corporation (RCBC) granted export loan lines to two sister corporations: Jigs Manufacturing Corporation (JIGS) and Elba Industries, Inc. (ELBA). JIGS received P2,500,000.00 while ELBA received P1,000,000.00, with additional amounts drawn from case-to-case arrangements and trust receipts.

Commonwealth Insurance Company (CIC) issued surety bonds securing these obligations. The bonds totaled P2,894,128.00 for JIGS and P1,570,000.00 for ELBA—a combined face value of P4,464,128.00.

When JIGS and ELBA defaulted, RCBC made written demands on CIC in October and December 1984. CIC made partial payments totaling P2,000,000.00 from February 1985 to February 1988, but a substantial balance remained unpaid. After a final demand in July 1988 went unheeded, RCBC filed a complaint for sum of money in September 1988.

The Issue

The sole question before the Supreme Court was whether CIC should be held liable to pay legal interest over and above its principal obligation under the surety bonds.

CIC argued that its liability could never exceed the bond amounts, citing the express stipulation in the bonds and the statutory rule limiting a surety's liability to the amount of the bond.

The Ruling

The Supreme Court denied CIC's petition and affirmed the Court of Appeals' decision. The Court distinguished between two types of liability:

Liability under the contract. As a surety, CIC could not be made to pay more than the amount stated in the bonds. This principle remains intact.

Liability under the law. Once CIC defaulted on its obligation upon valid demand, it incurred mora solvendi (delay in payment) under Article 1169 of the Civil Code. This delay triggered liability for damages and interest under Article 1170—a liability that arises not from the suretyship contract but from law.

The Court cited settled jurisprudence, including Tagawa v. Aldanese (1922), Plaridel Surety & Insurance Co. v. P.L. Galang Machinery Co. (1957), and Republic v. Court of Appeals (2001), all sustaining the principle that a surety who fails to pay upon demand can be held liable for interest even if the total exceeds the principal obligation.

The Rate of Interest

Applying the guidelines from Eastern Shipping Lines, Inc. v. Court of Appeals (1994), the Court held that since the obligation involved a loan or forbearance of money with no stipulated interest rate, the applicable rate was 12% per annum from the date of extrajudicial demand.

The Court rejected CIC's argument that its delay was not unreasonable because of ongoing settlement negotiations. The Court noted that CIC admitted owing the principal amount but still failed to pay the remaining balance of P2,464,128.00. Disagreements over interest did not excuse non-payment of the principal.

Interest ran from the extrajudicial demands: October 30, 1984 for the JIGS account and December 17, 1984 for the ELBA account—not from the filing of the complaint in 1988.

Practical Takeaways

• A surety's liability is not capped at the bond amount once it defaults. The cap applies only to the contractual obligation; interest from delay is a separate legal liability.
• Extrajudicial demand triggers the running of interest. Under Article 1169 of the Civil Code, delay begins from the time the obligee makes a judicial or extrajudicial demand.
• The applicable rate for loan or forbearance of money is 12% per annum when no rate was stipulated, computed from default.
• Ongoing negotiations do not excuse non-payment. A surety that admits owing the principal should pay it even while disputing interest charges.
• The Insurance Code contains provisions on unreasonable denial or withholding of insurance claims, but the specific section number could not be verified in available sources.
