G.R. No. 160347 ; November 29, 2006
Arcadio and Maria Luisa Carandang, Petitioners, vs. Heirs of Quirino A. de Guzman, namely: Milagros de Guzman, Victor de Guzman, Reynaldo de Guzman, Cynthia G. Ragasa and Quirino de Guzman, Jr., Respondents.

FACTS

Petitioners Arcadio and Maria Luisa Carandang and respondent Quirino de Guzman were stockholders and officers of Mabuhay Broadcasting System (MBS). The Carandangs subscribed to capital stock increases of MBS in 1983 and 1989. De Guzman claimed he advanced the total sum of ₱336,375 to pay for these subscriptions on behalf of the Carandangs. He sent a demand letter for repayment on March 31, 1992. The Carandangs refused, contending that a pre-incorporation agreement existed whereby de Guzman promised to pay for Arcadio’s subscriptions in consideration for his technical expertise and equipment, thus negating any loan.
De Guzman filed a collection suit on June 5, 1992. During the pendency of the case, de Guzman passed away. The Regional Trial Court (RTC) subsequently rendered a decision in favor of de Guzman, ordering the Carandangs to jointly and severally pay the amount. The Carandangs appealed, arguing the RTC decision was void as it was rendered after de Guzman’s death without a formal substitution of his heirs, and that no valid loan was proven.

ISSUE

The core issues were: (1) whether the RTC decision is void for failure to formally substitute the deceased plaintiff’s heirs; and (2) whether a loan obligation existed for which the Carandangs are liable.

RULING

The Supreme Court denied the petition and affirmed the lower courts’ decisions. On the procedural issue, the Court held that while de Guzman died before the RTC decision, his heirs were already named as respondents in the appeal and actively participated in the litigation. Formal substitution, while mandatory, is not jurisdictional when the heirs voluntarily appear, participate in the case, and present their claims without objection. Their active involvement cured any procedural defect, and they were considered properly substituted.
On the substantive issue, the Court found that a loan was duly established. The Carandangs failed to present the alleged pre-incorporation agreement. In contrast, de Guzman’s evidence, including the demand letter and testimony, proved the advance of money for the stock subscriptions with an expectation of repayment. The transaction constituted a loan under Article 1933 of the Civil Code. The Carandangs’ receipt and benefit from the funds obligated them to reimburse de Guzman. Their liability was correctly adjudged as joint and solidary, as the obligation was contracted by the spouses during their marriage, presumed to be for the benefit of the conjugal partnership.
