Heirs of Spouses Joaquin Manguardia v. Heirs of Simplicio Valles

Summary

This case involves a property dispute over Lot 835 in Ivisan, Capiz, originally owned by siblings Marta and Simplicio Valles. The heirs of Marta and Simplicio challenged the validity of a 1968 deed of sale and all subsequent transfers, claiming the original deed was forged since both alleged vendors had died decades earlier (Marta in 1943, Simplicio in 1957). The property had been subdivided and sold through various transactions among close family members, ultimately reaching the Manguardia and Araza families. The Supreme Court affirmed the lower courts' findings that the original deed was void ab initio due to forgery, and that subsequent purchasers were not buyers in good faith given the close family relationships and suspicious circumstances surrounding the transactions. The Court rejected defenses of prescription, laches, and estoppel, emphasizing that registered land cannot be acquired through adverse possession and that equitable doctrines cannot perpetuate fraud. The decision reinforced the principle that the burden of proving good faith purchaser status lies on those asserting such standing.
