G.R. No. L-61647 October 12, 1984
Republic of the Philippines (Director of Lands), petitioner, vs. The Hon. Court of Appeals, Benjamin Tancinco, Azucena Tancinco Reyes, Marina Tancinco Imperial and Mario C. Tancinco, respondents.

FACTS

The private respondents, registered owners of a fishpond in Meycauayan, Bulacan, filed an application for registration of three adjacent lots, later withdrawing one. They claimed these lots, Lots 1 and 2 of Plan Psu-131892, were accretions formed by the gradual deposit of silt from the adjoining Meycauayan and Bocaue rivers to their titled property. The Court of First Instance of Bulacan granted the application, finding the lots to be natural accretions. This decision was affirmed in toto by the Court of Appeals.
The Republic, through the Director of Lands, opposed the registration, contending the lots were not true accretions. The petitioner argued that the alleged alluvial deposits were man-made, resulting from the private respondents’ act of unlawfully transferring their dikes further into the riverbed around 1951, thereby reclaiming land from the public domain.

ISSUE

Whether or not Lots 1 and 2 are accretions to the private respondents’ titled land, registrable in their names.

RULING

No. The Supreme Court reversed the decisions of the lower courts, holding the lots were not accretions but portions of the riverbed reclaimed through human intervention. The legal logic centers on the requirements for accretion under Article 457 of the Civil Code. Accretion must be the gradual and imperceptible deposit of soil by the river’s natural action, compensating the riparian owner for the perils of erosion and floods inherent in riverside property.
The Court found the private respondents’ evidence insufficient to prove natural and imperceptible formation. Critical facts undermined the claim: the lots were not included in the 1940 survey of the adjacent property nor in the municipal cadastral survey from 1958-1960, and were only declared for taxation in 1972. This timeline contradicted testimony that the deposits existed as early as 1939. The evidence instead showed the deposits formed only after the dikes were moved in 1951. Since the increase in land was caused by deliberate reclamation works, not the river’s natural flow, it cannot be considered accretion. Consequently, the lands remain part of the public domain, inalienable and not subject to registration. The Court ordered the private respondents to return the property to the river by moving their dikes back to the original location.
