G.R. No. 121510 November 23, 1995
FABIANA C. VDA. DE SALAZAR, petitioner, vs. COURT OF APPEALS, PRIMITIVO NEPOMUCENO and EMERENCIANA NEPOMUCENO, respondents.

FACTS

Private respondents filed separate complaints for ejectment against petitioner’s husband, Benjamin Salazar, in 1970. After protracted proceedings, the trial court rendered a joint decision in favor of the private respondents in 1993. Benjamin Salazar had died in 1991, before this decision was rendered. An appeal was initially interposed in the name of the deceased husband and was dismissed by the Court of Appeals. Subsequently, petitioner filed a petition for annulment of judgment before the Court of Appeals, arguing that the trial court’s failure to effect a formal substitution of heirs after her husband’s death deprived the court of jurisdiction over her and the other heirs, violating their right to due process.
The Court of Appeals denied the petition for annulment. It found that while the general rule requires substitution of heirs upon a party’s death, formal substitution was not necessary under the circumstances. The appellate court noted that the heirs, including petitioner, had voluntarily appeared, participated in the case, and presented evidence in defense of the deceased. Petitioner’s motion for reconsideration was denied, prompting this petition to the Supreme Court.

ISSUE

Whether the trial court’s failure to effect a formal substitution of heirs before rendering judgment, following the defendant’s death, renders the judgment null and void for lack of jurisdiction.

RULING

The Supreme Court dismissed the petition, ruling that the judgment was valid. The requirement for substitution of heirs is rooted in due process, ensuring that the real parties in interest are notified and given an opportunity to be heard. Non-compliance is typically a jurisdictional defect that voids a judgment. However, the Court held that formal substitution is not an absolute requirement when its substantive purpose—to afford the heirs their day in court—has been satisfied.
In this case, the heirs, including petitioner, had voluntarily participated in the proceedings, presented evidence, and defended the interests of the deceased. By doing so, they effectively submitted to the court’s jurisdiction and were accorded due process. The failure to formally amend the caption of the case was a procedural lapse that did not prejudice their rights. Consequently, petitioner was estopped from challenging the judgment based on a lack of formal substitution, as she had actively litigated the case. The decision remained binding and enforceable against her as a successor-in-interest.
