Heirs of the Late Spouses Victor L. Montevilla v. Spouses Leo A. Vallena

Summary

The Supreme Court resolved an unlawful detainer dispute over a 40-square meter unregistered lot in Masbate. The Montevilla heirs claimed ownership through inheritance from Victor Montevilla, who allegedly gave tolerance to spouses Vallena to use the lot for their patis business with light materials only. When the Vallenas built a concrete structure, the heirs demanded vacation. The Vallenas claimed they owned the lot through purchase by Jose Vallena from Victor, but could only present photocopies of sale documents. The Supreme Court applied the best evidence rule and found the photocopies insufficient, lacking certainty of object required for valid contracts. The Court held that the Vallenas' judicial admission of Victor's original ownership established the Montevillas' prior possession. Based on preponderance of evidence including multiple affidavits, tax documents, and boundary owners' testimonies, the Court ruled the occupation was by mere tolerance and reinstated the lower courts' decision ordering vacation and rental payments.
