G.R. No. 154486; December 1, 2010
FEDERICO JARANTILLA, JR., Petitioner, vs. ANTONIETA JARANTILLA, BUENAVENTURA REMOTIGUE, substituted by CYNTHIA REMOTIGUE, DOROTEO JARANTILLA and TOMAS JARANTILLA, Respondents.

FACTS

The case originated from an amended complaint filed by respondent Antonieta Jarantilla against her relatives, including petitioner Federico Jarantilla, Jr., for accounting, partition, and delivery of her alleged 8% share in a co-ownership or partnership. Antonieta claimed that in 1946, she and other heirs of the Jarantilla spouses entered into an agreement to engage in business using inherited property and her subsequent annual investments. She asserted co-ownership over several real properties registered in the defendants’ names, contending these were purchased using partnership profits. During the RTC trial, petitioner, initially a defendant, entered into a compromise agreement with Antonieta, joining her claim and asserting his own 6% share in the alleged partnership.
The RTC ruled in favor of Antonieta and, by extension, Federico Jr., ordering the delivery of their respective shares in the subject properties. The Court of Appeals reversed this decision, finding no evidence of an overarching partnership or co-ownership encompassing all the disputed assets. The CA limited Antonieta’s interest to the specific businesses and share percentages acknowledged in a 1957 “Acknowledgement of Participating Capital” document. Petitioner elevated the case to the Supreme Court.

ISSUE

The core issue is whether the Supreme Court should uphold the Court of Appeals’ ruling that no universal partnership or co-ownership existed over all assets claimed, thereby limiting the petitioner’s and respondent Antonieta’s interests to specific, formally acknowledged business ventures.

RULING

The Supreme Court denied the petition and affirmed the Decision of the Court of Appeals. The legal logic rests on the distinction between a partnership and a co-ownership, and the requisite proof for each. The Court found that the elements of a partnership—the existence of a valid contract, mutual contributions to a common fund, and an intention to divide profits—were not conclusively established to create a single, overarching partnership covering all the diverse business ventures and real properties involved from 1946 onward. The 1957 “Acknowledgement of Participating Capital” was a key document that recognized interests in only three specified businesses, not a universal partnership.
Furthermore, the Court ruled that co-ownership under Article 484 of the Civil Code requires proof of common ownership of a specific property. Mere suspicion or allegation that properties were acquired using funds from a business arrangement is insufficient to establish co-ownership, especially when titles are registered in individual names. The respondents’ possession of certificates of title created a strong presumption of exclusive ownership. The petitioner and Antonieta failed to present clear and convincing evidence to overthrow this presumption and prove that the disputed real properties were assets of a universal partnership or co-ownership. Their interests were correctly limited by the appellate court to the specific capital participations formally acknowledged in the 1957 document and corporate shares they actually held.
