Maximo Jagualing v. Court of Appeals (Fifteenth Division)

Summary

This case involves a dispute over ownership of a 16,452 square meter island in the non-navigable Tagoloan River in Misamis Oriental. Private respondents claimed inheritance from their father while petitioners asserted adverse possession rights after 15 years of actual occupation. The RTC initially dismissed the complaint, finding the island was public domain. However, the Court of Appeals reversed, applying Civil Code provisions on accretion and riparian rights. The Supreme Court affirmed, holding that under Articles 463 and 465 of the Civil Code, islands formed by alluvial deposits in non-navigable rivers belong to the owners of the nearest margins. The Court ruled that petitioners could only acquire ownership through 30-year adverse possession as bad faith possessors, but had only possessed for 15 years. This decision clarifies the preferential rights of riparian owners over accretions and establishes important precedent on island formation and ownership in non-navigable rivers.
