Buenaventura v. Uy

Summary

This Supreme Court case clarified the distinction between forcible entry and unlawful detainer actions while addressing procedural requirements under Rule 70. Buenaventura leased property to the Uy spouses who occupied excess area beyond the leased premises. When demanded to vacate the excess portion, tenants refused, prompting an ejectment suit. The Court of First Instance dismissed the case citing jurisdictional defects due to unverified complaint and alleged late filing. The Supreme Court reversed, holding this was unlawful detainer (not forcible entry) since possession was initially lawful but became unlawful upon refusal to vacate. Importantly, the Court ruled that verification requirements are formal, not jurisdictional, and defects can be corrected without affecting the court's jurisdiction. The decision reinforced that municipal courts retain jurisdiction over properly filed ejectment cases even with procedural defects that can be cured through amendment.
