Felicito Tan v. Hon. Intermediate Appellate Court (Third Civil Cases Division)

Summary

This case involves a property dispute over inherited land among the Martos siblings and Philippine National Bank. The siblings claimed fraud in loan documents that used their inherited property as collateral. The trial court and appellate court initially ruled for the siblings, finding the documents fraudulent. However, the Supreme Court reversed, finding that the loan documents were validly executed based on credible testimony from government officials and the notary public. The Court held that the presumption of regularity in official duties was not overcome by the siblings' self-serving denials. Importantly, the Court distinguished Victoria Martos' position, ruling she could not be bound by the mortgage since she had no knowledge of it and received no benefit. The decision demonstrates the importance of due execution of documents and the protection of innocent co-owners in property transactions.
