Sps. Esmeraldo D. Vallido v. Sps. Elmer Pono

Summary

This Supreme Court case involved a double sale of an 18,214 square meter portion of land originally owned by Martino Dandan. In 1960, Martino sold the portion to Purificacion Cerna who later sold it to Marianito Pono in 1973, but neither sale was registered. In 1990, Martino sold the entire property to his grandson Esmeraldo Vallido, who eventually registered the sale in 1999. The RTC initially favored the Vallidos as good faith purchasers and registrants, but the CA reversed, finding they were not in good faith since the respondents were in actual possession. The Supreme Court affirmed the CA, ruling that as heir of the original vendor, Esmeraldo had constructive knowledge of prior dispositions and failed to exercise due diligence by not investigating the actual possessors of the property. The Court emphasized that several warning signs should have prompted inquiry, including the vendor's lack of possession and the presence of permanent improvements. The decision reinforced the principle that good faith requires actual diligence in property transactions.
