1. Interest Stipulation Rule
Under Article 1956 of the Civil Code, no interest shall be due unless it has been expressly stipulated in writing. An oral agreement or a unilateral demand by the creditor for interest upon late payment is legally void. Furthermore, under Article 1169, legal delay (mora) arises only from the moment the creditor judicially or extrajudicially demands fulfillment. Without a prior written demand or express written stipulation, an obligor who pays after the due date is not in legal delay and is under no civil obligation to pay interest.
2. Solutio Indebiti Principle
Under Article 2154 of the Civil Code, solutio indebiti occurs when something is received when there is no right to demand it, and it was unduly delivered through mistake. In such cases, the recipient comes under a quasi-contractual obligation to return the money or property received. Paying interest that was neither agreed upon in writing nor legally due constitutes an undue payment by mistake. Such payment cannot be considered a voluntary performance of a natural obligation because natural obligations presuppose a moral duty, which does not exist for un-stipulated interest.
3. Civil Versus Natural
Under Article 1423 of the Civil Code, obligations are classified into civil and natural obligations. Civil obligations give a right of action in a court of justice to compel their performance or enforcement, as they arise directly from law, contracts, quasi-contracts, acts punishable by law, and quasi-delicts. In contrast, natural obligations are not based on positive law but on equity and natural law. They do not grant a right of action to enforce performance, but after voluntary fulfillment by the obligor, they authorize the retention of what has been delivered.
