G.R. No. 76148 December 20, 1989
ELISEO CARO, CARLOS CARO, BENITO CARO, CARMEN CARO BATAYOLA AND LORENZO CARO, petitioners, vs. HON. COURT OF APPEALS, SERAFIN V. RONZALES, JOSE RONZALES, JR. AND GEMME RONZALES, respondents.

FACTS

The petitioners, heirs of Epifanio Caro, sought the cancellation of Original Certificate of Title No. 0-6836 issued to the private respondents (the Ronzaleses) and the reconveyance of a 260-square-meter parcel of land. They claimed this lot was included in a larger tract purchased by Epifanio from Simeon Gallego in 1948. Epifanio later acquired two adjacent parcels, and in 1963, all three were consolidated and surveyed as Lot No. 54. During subsequent cadastral proceedings, Epifanio filed an answer for Lot No. 54. The disputed portion was separately surveyed as Lot No. 55. The private respondents, through their mother Purificacion Ronzales, filed the sole answer for Lot No. 55, leading to the issuance of an OCT in their names in 1970. Epifanio Caro filed a complaint for reconveyance based on fraud in 1975, alleging the Ronzaleses knowingly included his land in their claim.

ISSUE

The core issues were whether the action for reconveyance had prescribed; whether fraud attended the issuance of the respondents’ title; and whether the petitioner’s predecessor-in-interest was in estoppel.

RULING

The Supreme Court affirmed the appellate court’s decision dismissing the complaint, primarily on the grounds of estoppel and absence of fraud, but modified the ruling by rejecting prescription as a ground. The Court found no conclusive evidence of fraud. The respondents and their predecessors had openly occupied the disputed lot long before the registration, constructing a house and declaring it for tax purposes in the name of Pascuala Lacson. Epifanio Caro was aware of this occupation and the separate identity of Lot No. 55, yet he took no action to oppose the respondents’ cadastral answer or assert his claim during the registration proceedings. His negligence and inaction—failing to verify survey plans due to his lack of formal education and relying solely on his own knowledge—constituted estoppel by laches. By sleeping on his rights, he was now barred from challenging a title issued under a Torrens system proceeding where he had the opportunity to be heard. The Court emphasized that an action for reconveyance based on an implied trust prescribes in ten years, and since the title was issued in 1970 and the suit filed in 1975, prescription did not apply. However, the petitioner’s estoppel, not prescription, was fatal to his case.
