Leon Oracion v. Pacita Juanillo

Summary

This three-cornered property dispute involved a donation made in 1923 by Cecilio Juanillo to Francisco Principe, which was later revoked by operation of law when Juanillo's legitimate daughter Pacita was born in 1934. Leon Oracion obtained a judgment against Juanillo and purchased the property at execution sale, but the Supreme Court held this sale was ineffective since the property belonged to Principe, who was not a party to the original judgment. The Court ruled that while the donation was revoked and the property should revert to Pacita Juanillo as heir, Oracion retained his right to collect the underlying debt of P300 as a lien against the property. The case demonstrates the application of Civil Code provisions on donation revocation due to supervening legitimate children and the legal principle that execution cannot affect property belonging to non-parties to the judgment.
